The shield in the centre shows cotton, wheat, tea and jute. These are the main crops of Pakistan and signify the strong agricultural based economy. Paki-stan, a country with a major textile industry, has in recent years developed into one of the most signifi -cant markets for Rieter Spun Yarn Systems. To emphasize the importance of the textile industry, here are some facts:

The textile industry contributes over 10% to the GNP of the countryThe exports amount to approx. 8,3 billion US$ p.a.40% of the working population are employed in the textile industryPakistan is the fourth largest cotton producer in the worldPakistan has approx. 456 spinning mills with a ca-pacity of more than 10 million spindles and more than 146 600 rotors. (Source APTMA)

These few facts show that the textile industry is one of the most important pillars of Pakistan’s economy.Cotton with approx. 74% is still the raw material with the greatest importance. However, chemical fi -bres and in particular Polyester are increasingly gain-ing in signifi cance. The Pakistani textile industry continues, as also was the case in the past, to make great eff orts in the fi elds of quality, productivity and service to be counted among the best worldwide. To demonstrate the industry’s unbroken belief in the future, the following three spinning mills are pre-sented as reference plants: Saif Textile Mills installed their new plant in late 2003, while the others com-menced production recently. The company portraits show that they clearly want to penetrate the qualita-tively higher-class market segment.

TRENDS & MARKETS

PAKISTAN, AN IMPORTANT MARKET FOR RIETER

Alongside these three companies, Rieter is proud to be “the preferred system supplier” chosen by many Pakistani customers, whether as supplier of individ-ual machines, sub-systems such as blowroom and carding, combing systems or complete plants, as in the case of the following three companies. SAIF TEXTILE MILLS LTD (STM). The Saif Group is owned by the Saifullah family with location in the North West Frontier Province of Pakistan, near the border with Afghanistan. The fi rst business estab-lished by the family was a thermal power plant in 1927. Subsequently, the family branched out into food processing in 1940 and then into textiles with Kohat Textile Mills Ltd in 1969 and Frontier Textile Mills Ltd in 1974. Since then the group has diversifi ed into power gen-eration, energy exploration, telecommunications, in-formation technology and real estate development. Saif Textile Mills Ltd. located in the Gadoon – Ama-zi Industrial Estate, 100 kilometres north west of Is-lamabad commenced production in 1992. Over the years, STM has consistently upgraded the machinery as well as expanded the capacity and prod uct range with the result that today it is a lead-ing player in the compact yarn segment in Pakistan, having successfully installed a complete Rieter spin-ning mill (Unit 3) with 19 K 44 compact spinning machines. Today Saif Textile Mills Ltd operates with a total in-stalled capacity of 89 000 spindles. STM has an annual turnover of more than Rs 4 bil-lion, and exports have grown from a base 0 to Rs 800 million p.a. in the last two years. STM is ISO 9002 and SUPIMA® certifi ed while ISO 14001, SA 8000 and GIZA® certifi cations are in process. The CEO of STM, Mr. Osman Saifullah Khan is a for-mer Central Vice Chairman of APTMA. In addition, he has also served as Chairman APTMA NWFP Zone.

All the compact yarn is for shirting exported main-ly to Europe. It is sold under the Saif brand directly to weavers, but also to manufacturers in Europe who have outsourced their spinning to us. Unit 3 was installed in two phases, with 8 K 44 compact spinning machines in the fi rst phase and 11 machines in the second phase. Osman Saifullah Khan’s philosophy has always been to exploit the unique characteristics of the K 44 machine by focusing on the unrivalled quality yarn it produces.

STATEMENTS BY OSMAN SAIFULLAH KHAN, CEO OF SAIF TEXTILE MILLS LTD. “The decision to choose Rieter was based on three essential parameters: Firstly, the excellent quality of the machines, second-ly the consistency of quality, fi nally, the fact that the market we focus on can only be properly served with Rieter COM4 K 44 yarn.” Unit 3 produces currently 100% combed cotton yarn in a count range from Ne 40 to Ne 140. Approx-imately 250 to 300 tons of Giza cotton is used per month with a production capacity on the K 44 of around 4,5 tons per day at an average yarn count of Ne 55.

A total of 19 152 spindles for producing COM4 yarns are installed at Saif Textile Mills.Saif Mills is a pioneer producer of COM4 yarns in Pakistan. The world’s best weavers of shirting fabrics use fi ne yarns from Saif Mills. That’s the reward for taking a courageous innovation lead.

5 Rieter . LINK 48 . 2/2006

He adds; “Some spinning mills focus on productivi-ty advantages and raw material upgradation possi-bilities provided by this machine, which essentially means using cheaper raw material, running at a high-er speed and ending up with a lower cost level.” He prefers the STM approach of producing the highest quality yarn, which is only possible on this kind of machine. Osman Saifullah Khan stated that they are very well established as one of the leading fi ne count spinners in Pakistan for conventional ring yarn. But they are also very well aware of the requirement for the shirt-ing market, which is a completely diff erent league, as the appearance of the yarn as well as the strength has to be much better and on top of that the hairi-ness is a critical issue. This is really where they are focussed. As far as shirting is concerned, they are the producer who can compete with anyone, any mill, anywhere in the world and this they are doing.

DEWAN FAROOQUE SPINNING MILLS LIMITED (DFSML). Dewan Mushtaq Group is one of Pakistan’s biggest private industrial conglomerates with an an-nual turn over of $417 million and assets of $480 million. The group is a major local producer manu-facturing a full range of textiles including cotton and man-made fi bers. DMG provides direct employment to over 12 000 people. The history of DMG goes back to the year 1916, when a small cottage industry was set up to manu-facture garments. The fourth generation of the Dewan family is now aggressively expanding and di-versifying in the fi elds of acrylic fi ber, automobiles and motorcycles, sugar, cement and trading. DMG instituted Dewan Farooque Spinning Mills Limited in January 2004 to gain a leadership position in the quality yarn market. DFSML has an installed capacity of 28 800 spindles, capable of producing quality yarns from medium to fi ne count yarns. 14 400 spindles are G 33 conventional ring spin-ning machines and the rest of the capacity are K 44 compact spinning machines. This state-of-the-art spinning unit from Rieter is currently producing ap-prox. 3,4 million kg of yarn p.a. The product range includes 100% cotton based combed yarn from Ne 30s - Ne 80s and combed com-pact yarns from Ne 40s - Ne 120s.

The reason as to why we acquired this state-of-the-art production technology from Rieter is because Rieter have a spinning integrated installation system from a single source thus enabling them to provide fl exible systems tailored to the requirements of yarn quality and customized automation options available from the start to the end of the spinning process.” For example, the SPIDERweb. SPIDERweb is the most advanced mill monitoring system, which gives a detailed view of the mill manufacturing process. All necessary information is available at a glance. Data transparency and optimized information fl ow give faster reaction time, which is imperative for any mill to run smoothly. Baqi Dewan also added: “We have taken this de-cision after an extensive evaluation of other com-pact yarn spinning machines by diff erent suppliers. We have conducted extensive tests and surveys of all yarn attributes like (strength, elongation, hairiness, etc.). Rieter K 44 yarn parameters are very suitable for our requirements. With K 44 machines, we can meet specifi c quality and price ratio demanded by our quality conscious customers.”

DFSML ensures that all relevant certifi cations like ISO 9000, ISO 14000, SA 8000, OEKO TEX etc. are obtained.

STATEMENTS BY BAQI DEWAN. “We have a long his-tory in textiles and we excel in spinning. Presently, we are using 100% cotton and also blended fi bers for the production of high quality export oriented yarn.” “We have set up our mills in Punjab, an area with more weavers active in the air-jet weaving sector. As you may already know, the air-jet looms require better quality yarn. The strength of compact yarn is higher than normal yarn and compact spun yarn has a better abrasion resistance. The fabric produced is better in terms of strength, elongation, low hairiness, low twist, low abrasion and improved uni formity.” “As for the question of why Rieter, I would like to emphasize the fact that we prefer to buy the com-plete plant from one supplier, and Rieter has a com-plete solution for all our needs. Furthermore, Rieter has a well-proven technology and they are very much focused on bringing out new innovations in their re-spective fi eld.”

DIN GROUP OF COMPANIES. Din Group is primarily engaged in leather and textiles. S.M. Muneer, former President of the Federation of Pakistan Chambers of Commerce and Industry, heads the group. The group has shown consistent growth over dec-ades with a turnover of over Rs 4 billion and they employ more than 3 500 people in the leather, chemi-cals and textile division.

DIN TEXTILE MILLS LIMITED. Founded in 1987 with only 18 years of experience it has emerged as one of the leaders in value added yarn production in Pakistan. Din Textile has three units, with 61 728 spindles totally and more than 2 400 employees. The fi rst two units manufacture and export 100% cotton yarn, mélange yarn, cone dyed yarn, slub yarn and elastic core yarn. Din Textile has started production of 100% com-pact yarn at its latest unit with 24 192 spindles on Rieter K 44 compact spinning machines.

CERTIFICATION. Din Textile is an ISO 9002 and ISO 14001 certifi ed company. They are committed to take all necessary measures to minimize adverse en-vironmental impact of their production and prevent pollution through proper environmental manage-ment.

COMPANY VISION. The vision of Din Textile is to pro-duce yarns of the fi nest quality for their customers who own global brands. The strict quality policy is maintained through quality objectives based on cre-ativity, skill development and continuous improve-ment.

STATEMENTS BY S.M. NAVEED, DIRECTOR, DIN TEX-TILE MILLS LTD. Why did you decide to go for compact yarn production?“The local as well as the international demand for yarn and fabric has increased by approximately 10 to 15% p.a. In view of this anticipated growth, Din Textiles set up their third unit to produce compact yarn. Believing in doing something unique which gives us an edge over our competitor, compact yarn was our natural option.”

What future do you see for compact yarn in Pakistan? “I see a very bright future for compact yarn in Pa-kistan. Not only reduction in hairiness but also other characteristics of compact yarn make it very attrac-tive. When we use compact yarn, which is higher in strength by 20 to 25% than normal yarn, it signifi -cantly improves the effi ciency of the looms. It can be safely said that the market share of com-pact yarn will continue to increase every year.”

What made you decide in favour of Rieter COM4 spinning? “Our reasons for choosing Rieter’s compact spin-ning system are very clear. Their technology is a prov-en technology. Rieter is defi nitely more expensive than other suppliers of compact systems. However, the cost of maintenance of Rieter’s machines is so low that the signifi cant savings in maintenance more than off set the higher initial investment. After much deliberation we decided to go for Rieter and it was a decision we don’t regret.”

The processing of Lyocell microfibers throughout the spinning process was studied using different spinning processes in the context of cooperation between Lenzing and Rieter.

TECHNOLOGY

TENCEL® MICROFIBERS – PROPERTIES AND PROCESSING

In the context of cooperation with Lenzing, the pro-cessability of Micro Lyocell fi bers with the Tencel® trademark using Rieter spinning machines was stud-ied from fi ber to yarn in a count range from 10 to 30 tex (Ne 60-20) and continued through to woven and knitted fabrics. The aspects of interest include the performance limits of the microfi bers on cards of conventional design and on the C 60 card with its unique working width of 1,5 meters. Raw material selection was based on the estab-lished fi nding that Lyocell microfi bers set very high standards for the spinning process.

ENVIRONMENTALLY COMPATIBLE PRODUCTION OF LYOCELL. Lyocell is the generic term for fi bers manu-factured from cellulose using a direct solvent proc-ess. The initial raw material is wood. Tencel® is pro-duced using this production process. This solvent spinning process is an environmentally friendly fur-ther development of cellulosic fi ber technology. The special feature of this process is the almost total re-circulation of the solvent. 99,5% of the solvent is recovered, and the very small emissions remaining are degraded in specially adapted biological clarifi -cation plants. Depending on the manufacturer, Lyocell raw mate-rial has been off ered on the market in the past under the Lyocell and Tencel trademarks. Lenzing acquired the Tencel Group in May 2004. Since March 2005 Lyocell fi ber from both manufacturing sites in Eng-land and Austria has been marketed under the uni-form Tencel® trademark.

Fig. 1 Tencel® fi bers are used in a wide variety of applications, such as sports, clothing and bed linen.

SUMMARY OF THE STUDY‘S OBJECTIVES. The study was intended primarily to obtain information on the following aspects of processing Tencel microfi bers:

the performance limits of the C 60 card, also in comparison to conventional cards compactability with COM4 compact spinning tech-nology using the K 44 compact spinning machine the yarn count that can be achieved using rotor technology with the high productivity of the R 40 rotor spinning machine

THE C 60 CARD. In the fi ne thin and thick places the C 60 card system displays the same yarn values as the C 51 with an 80% increase in output. At the same card output of 35 kg/h the IPI values on the C 60 system are approx. 20% lower. The carding forces are therefore directly related to carding quality, es-pecially when using man-made microfi bers. The C 60 carding system off ers considerable advantages in terms of productivity and quality, especially with man-made fi bers, where carding forces are general-ly high.

SPECIFIC PROPERTIES OF TENCEL®. Generally speak-ing, cellulosic fi bers display very good moisture absorbency, better than that of cotton, and they dye readily, are antistatic, have a soft handle, are pleasant to the skin and easy-care. Compared with other cellulosic fi bers, such as viscose and Modal, Tencel® features higher wet strength (cf. Table).

ADVANTAGES OF MICROFIBERS. Microfi bers enable fi ner or stronger yarns to be produced. Knitted and woven fabrics manufactured from them have a silky appearance and drape. They have a pleasant feel, and the luster of the fabric and its moisture transport are improved. The larger the fi ber surface, the more effi cient the moisture transport. When microfi bers with a count of 0,9 dtex are used, moisture transport with the same yarn count can be increased by about 50%. By comparison, the fi bers usually have a count of 1,3-1,5 dtex.

DIVERSE FIELDS OF APPLICATION. Tencel® is to be found in a very wide range of applications; in sports-wear and leisurewear Tencel® absorbs more wa-ter vapor than cotton and thus ensures optimum moisture transport. In shirts and blouses the fi ber guarantees an ideal fi t and dimensional stability as well as outstanding wearability. In bed linen an ide-al sleeping climate is created – cool in summer and comfortably warm in winter. Demand for Tencel® will increase as more fi elds of application in woven and knitted goods are added in future. Tencel® fi ber is labeled with the Lyocell raw materi-al name in textile items.

ROTOR SPINNING. The Lyocell microfi bers we stud-ied displayed excellent running properties on the R 40 rotor spinning machine. A 10 tex yarn was spun with a twist factor of αm 100 at the high rotor speed of 130 000 rpm. Despite the low number of 110 fi -bers in the cross-section for rotor spinning, high pro-ductivity was achieved with very good running pro-perties. This productivity advantage is the result of the mod-ern OE rotor spinning technology of the R 40. The unique SPEEDpass, for example, has proved to be of great advantage when processing these microfi bers.

SOUTH PACIFIC VISCOSE SPINNING CENTER. The re-sults briefl y described above are the outcome of co-operation between Rieter and the Lenzing Group. One aspect of this cooperative venture is the instal-lation of a state-of-the-art fi ber process unit (test spinning mill) in Purwakarta, Indonesia. This in-stallation consists of a B 34 S bale opener, a C 60 card, SB-D 15 and RSB-D 35 drawframes, an R 40 rotor spinning machine and a G 33 ring spinning ma-chine. The objective is to encourage improvements and innovations in the processing of viscose using the short staple fi ber process and to improve quality through tests and selective fi ne tuning. Everyone gains from this cooperative venture. Cus-tomers benefi t because the fi bers are adapted per-fectly to the requirements of the diff erent spinning processes, processing know-how is available in the form of recommendations and the machines can be adapted to the raw material if necessary.

More information on Tencel at: www.lenzing.com

Especially when processing microfi bers, where card-ing output to date has been limited to a maximum of approx. 35 kg/h, the new C 60 carding system can raise the limits for increased production. Output of up to 63 kg/h amounts to an 80% increase in perfor-mance. This considerably increases the attractions of processing microfi bers and sets new standards in card output.

COMPACT SPINNING. Micro Lyocell is notably suc-cessful in compacting up to a yarn count fi ner than 30 tex. Hairiness was reduced very substantially in com-parison with conventional ring spinning technology with a very fi ne yarn of approx. 10 tex. At the same time tenacity increased by up to 3,5 cN/tex.

TOP QUALITY DUE TO INDEPENDENT AUTOLEVELING SYSTEM. The RSB-D 40 single-head autoleveler draw-frame (cover illustration) stands out for its high autoleveling and thus sliver quality. This is also guar anteed by the independent operation of the au-toleveling system. By contrast, a double-head auto-leveler drawframe has the disadvantage - by virtue of its design - that the drives of both autoleveling systems are connected via a common drawframe sys-tem delivery roller. The two autoleveling systems therefore infl uence each other and this results in low-er sliver quality.

Rieter was the first manufacturer to introduce the concept of single-head autoleveler drawframes some 25 years ago. This concept offers quality and opera-ting advantages and has since continued its victorious progress even in traditional double-head markets such as Asia.

TECHNOLOGY

ADVANTAGES OF SINGLE-HEAD OVER DOUBLE-HEAD AUTO-LEVELER DRAWFRAMES

A crucial factor in sliver quality is accurate coordi-nation of mechanical systems, drive, electronics and software. Our experienced, interdisciplinary product development team therefore coordinated these com-ponents precisely. Double-head drawframes with au-toleveling components from diff erent manufacturers therefore do not produce even remotely comparable autoleveling results. The signifi cantly better sliver regularity and coil-ing free of sliver breaks on the RSB-D 40 result in higher productivity on roving frames, spinning ma-chines and winders as well as higher roving and yarn quality.

CONSISTENT QUALITY DUE TO FEWER AUTOLEVEL-ING SYSTEMS. Especially when several autoleveler drawframes are feeding one blend, accurate adjust-ment of the required sliver count on each individu-al drawframe is of crucial importance. Any incor-rect setting of the required sliver weight, caused for example by errors in determining the weight in the laboratory, directly increases variances in yarn count throughout the blend. In mill operations this is frequently a reason for fl uctuations in yarn count (Fig. 1). Due to the high productivity per head of the RSB-D 40, the number of leveling adjustments is much smaller than on double-head drawframes run-ning slowly and with lower effi ciency. Consequent-ly, the danger of personnel-induced fl uctuations in sliver count and thus yarn count is reduced with the RSB-D 40.

PRODUCTIVITY DUE TO HIGH DELIVERY SPEED AND EFFICIENCY. The productivity of the RSB-D 40 sin-gle-head drawframe compared with a double-head drawframe is incorrectly rated when the calcula-tion is simply based on speeds quoted in sales lit-erature and the number of heads. In the case of the RSB-D 40, delivery speeds of 850 m/min are already standard in mill operations when processing carded cotton in ring spinning applications. In a European rotor spinning mill the RSB-D 40 has been operating continuously for more than a year at delivery speeds between 1 000 m/min and 1 100 m/min, producing an Ne 20 cotton yarn.

drafting system head comes to a standstill on the RSB-D 40 – instead of two heads in the case of the double-head drawframe. This advantage increases with rising delivery speed. In addition, the robust rotary can changer, the empty can magazine with up to 8 reserve cans, trouble-free operation and long cleaning intervals in the drafting system zone result in high effi ciency on the RSB-D 40. Productivity is therefore also more independent of operators‘ infl u-ence.

SIMPLICITY DUE TO GOOD ACCESSIBILITY. Accessi-bility is considerably better on the Rieter single-head drawframe than on any double-head drawframe, i.e. operating, adjusting and maintenance work can be performed more easily and therefore faster. This simplicity also motivates personnel to carry out op-timization and maintenance operations willingly – quality and machine availability are assured.

FEWER TRANSPORT MOVEMENTS AND SLIVER PIE-CINGS DUE TO LARGE CAN FORMATS. The use of feed cans with a diameter of 1 000 mm in a short, 2-row creel only makes sense on single-head drawframes in terms of the accessibility of the slivers and thus pro-ductive working methods. The SB-D 40 (without autoleveling) enables 1 000 mm delivery cans to be fi lled. Double-head drawframes of Asian design can only fi ll cans up to 400, 500 or 600 mm. This amounts to as many as 200 000 fewer can transport movements and sliver piecings a year per Rieter drawframe and thus cor-responding benefi ts in terms of operator eff ort and quality (Fig. 3). One of our customers in Asia has re-duced clearer cuts on the winder by 10% by using the larger can formats.

In addition to the delivery speeds of the RSB-D 40 in mill operations, production effi ciency is 10% to 20% higher than that of double-head drawframes with autoleveling: at each sliver breaks in a feed can, can change at the infeed or delivery end, ma chine malfunction or maintenance operation, only one

The prerequisite for producing quality yarns is a high-quality spinning line. The preparatory stage, i.e. the roving frame, is very important here. Conti-nuous further development and improvement result-ed in the replacement of the well-known F 11 / F 33 roving frame models by the F 15 / F 35 successor models last year. For users, new advantages that are

The new F 15 and F 35 roving frame models offer great er flexibility and improved economy. High quality at the preparatory stage is maintained.

PRODUCT NEWS

CONTINUITY IN ROVING MANUFACTURE

refl ected primarily in high fl exibility and increased productivity are added to the already familiar and proven features. FOUR MODELS OFFER INDIVIDUALITY. Instead of the two existing models, a choice can now be made be-tween four diff erent models. Basically, the choice is between the F 15 manual roving frame and the ful-ly automated F 35 roving frame. Both models are additionally off ered with gauges of 110 mm and 130 mm. The advantage of the smaller gauge of 110 mm is that it can off er up to 160 spinning positions. Max-imum bobbin size in this case is 6 inches. With a gauge of 130 mm up to 144 spinning positions can be used, and 6 and 7-inch bobbins can be produced. These options enable an individual response to be made to customers‘ requirements.

USER-FRIENDLY DESIGN. Accessibility and thus op-eration of the spindles has been improved consid-erably. This is evident both from the new design and from the ergonomic structural concept of the ma chine. The redesign of the F 35 doff er model has enabled the front of the machine to be made more open. Only two supports are now needed here along the whole machine length.

OPTIMIZED DRIVE SYSTEM. The redesigned drive system enables customers to benefi t from reduced maintenance eff ort and signifi cantly lower noise levels. The familiar and proven multi-motor drive sys-tem has been further optimized. The diff erential gear used to date is no longer necessary. Both the spindles and the fl yers are now driven directly via a servo motor.

EASIER HANDLING. The new machine concept sim-plifi es machine operation and setting. Important pa-rameters can be adjusted at the control panel. The machines are equipped with touchscreens. The new control system enables 20 diff erent settings to be stored; these are available at any time. Especial-ly in the case of frequent batch changes, this is very effi cient, makes a major contribution to quality con-sistency and considerably simplifi es the operator‘s work.

It is advisable to equip the roving frame with the ROJ individual roving monitor (option), especially for man-made fi bers, blends, dark raw material and long machines. Customers benefi t from numerous advantages – no false stoppages; individual, auto-matic monitoring and detection of roving ends down; prevention of lap formation; statistical analysis for systematic improvement of running properties. This results in a substantial improvement in roving frame economy.

OPTIMIZED ENERGY CONSUMPTION. The new roving frame models are equipped with increased in stalled power due to the redesigned drive system and the longer machines. Suffi cient power is thus guaran-teed, even for very long machines. Energy consump-tion is unchanged compared with the predecessor model.

ADVANTAGES OF A SYSTEMS SUPPLIER. Especial-ly in the case of the F 35 automated roving frame, customers benefi t from the fact that Rieter is a sys-tems supplier. SERVOtrail – the Rieter transport sys-tem for roving frame bobbins – is ideally coordinated with the machines and can be confi gured with total fl exibility.

POSITIVE RESPONSE. More than 80 F 15 / F 35 ro-ving frames have been sold since the model replace-ment in 2005. The high level of demand is a positive signal for the new roving frame models.

PROVEN ROVING QUALITY. High quality standards are maintained with the new roving frame models. The pneumatically loaded drafting system is an im-portant technological component. Constant pressure ensures maximum roving uniformity over the entire length of the machine. The guide arms are centrally balanced, and the pressure is infi nitely adjustable. The standard version of the machine is equipped with a 3-over-3-cylinder drafting system. A 4-over-4-cylinder drafting system can also be supplied as an option. As was the case on the predecessor model, the new F 15 / F 35 generation of roving frames can be equipped with the proven ROJ roving autolevelling system. Roving tension is monitored and kept constant by means of two sensors and a microprocessor. This en-sures high yarn uniformity and prevents incorrect drafts.

HIGHLY ECONOMICAL. In addition to output as such, doffi ng time is also known to have a major impact on roving frame productivity. On the fully automated F 35 roving frame the doff -ing process is twice as fast as on most other roving frame models available on the market. Separate actuation of the bobbin rail and the doff er bar are the basis for this very short doffi ng time. Both elements are controlled by frequency converters and can thus be moved synchronously and independently of each other. The doffi ng process is shortened consid-erably and doffi ng times of less than 2 minutes are reality. Machine length is of no consequence for this. Machine effi ciency is thus considerably increased.

YARN INNOVATIONS WITH CORE YARN TECHNOLOGY

THE SPOERRY SPINNING MILL IN FLUMS, SWITZ-ERLAND. The Spoerry spinning mill in Flums has al-ways been one of the world‘s most progressive and innovative spinning mills. With its outstanding pro-duction know-how and the corresponding machines and equipment, Spoerry repeatedly attains, rein-forces and extends its market leadership with out-standing products. Spoerry Sensual is one of the products manufac-tured on Rieter ring spinning machines equipped with the Rieter core yarn device for fi ne-count yarns with an elastic fi lament core.

COMPACT CORE YARN APPLICATIONS. The COM4 spinning process and the specially developed core yarn system enable various fi laments to be position-ed accurately in the center of the strand of compact-ed fi bers. The fi bers are then spun carefully around the core. In production operations a distinction is made bet-ween yarn counts of Nm 85-135, which are spun with a 22 dtex fi lament core, and especially fi ne yarns of Nm 135-250 with a fi lament of 15 dtex and fi ner. These superfi ne yarns are unique in terms of fi ne-ness, elasticity and yarn structure. Their reduced hairiness guarantees especially high wearing com-fort. Superfi ne textiles made from SPOERRY SENSUAL are so soft that they feel like a second skin. They are particularly suitable for manufacturing tights, body-suits and exclusive lingerie. In addition to classical cotton, high-quality material such as cashmere, baby alpaca and silk can also be used here. Yarns from the SPOERRY SENSUAL family, pro-duced on Rieter COM4 spinning machines addition-ally equipped with the Rieter core yarn device can thus be used everywhere: from superfi ne fabrics for elastic blouses to shirts and high-quality bed linen.

Fig. 1 The superfi ne textiles hug the body like a second skin and guarantee high wearing comfort.

THE LAUFFENMÜHLE SPINNING MILL IN WALDSHUT. This is one of the most innovative fabric manufactur-ers in Europe, supplying a wide range of products. It is also a leading manufacturer of workwear. It is no longer possible to imagine the world of fash-ion without elastic yarns and the elastic fabrics pro-duced from them. Due to their high level of wearing comfort it is not surprising that demand for elastic fabrics in workwear is also increasing continuously.

NEW, INNOVATIVE PRODUCTS STRENGTHEN THE COMPANY‘S MARKET POSITION. An elastic yarn with the product name EVOLUTION is being manufac-tured on a G 33 ring spinning machine that has been retrofi tted with the Rieter Core Yarn System. This core-spun yarn is produced using the novel DOW XLA fi lament fi ber, which is especially suitable for manu-facturing elastic, yet hard-wearing workwear fabric. The new fi ber made from Lastol is polyolefi n-based and extremely heat- and chemical-resistant. The transparent fi bers are completely integrated in the yarn, absorb little moisture, are UV-resistant and provide permanent elasticity, even after repeated in-dustrial washing.

TEST PASSED. The above examples clearly demon-strate how exceptional market positions can be at-tained with the customer‘s technological know-how and appropriate technical equipment from the ma-chinery manufacturer. Rieter customers also benefi t from a high level of product know-how in the core-spun yarn sector with the Rieter Core Yarn System as an option for new ComforSpin and classical ring spinning machines, and also as a retrofi t for Rieter G 5/1 to G 33 ring spinning machines. In conjunction with off erings ranging from product defi nition through service and thanks to technolog-ical experience, customers obtain added value for their investment.

ROTOR SPINNING TRENDS. It is generally accepted that rotor-spun yarns are diff erent from ring-spun yarns. In terms of applications the prevailing ap-proach has been to utilize rotor technology for mass production, mainly in the denim sector. However, in addition to the widely accepted advantages in proc-essing rotor-spun yarns, extensive progress has also been made in improving the quality and properties of rotor-spun yarns. These can multiply the proven benefi ts in productivity by extending the applica-tions of rotor spinning into other areas.

Technological innovations in rotor spinning enable spinning mills to use rotor spinning machines for a wider range of applications and exploit productivity benefits.

EXTENDING THE SCOPE OF ROTOR SPINNING

THE SEMI-AUTOMATIC BT 923 FROM RIETER WITH THE NEW C 120 SPIN BOX OFFERS WIDER SCOPE. The benefi ts are extremely important, especially for Asian markets, where semi-automatic machines in particular fi nd their place and where several trends are in progress:

a shift from domestic markets to exportsand consequently also processing new materials on semi-automatic rotor spinning machines and fi nally new applications including, for exam-ple, knitting yarns.

The previous generation of Rieter semi-automatic machines was famous for processing cotton fi bers and blends with diff erent kinds of waste, such as comber noils, fl at strips or regenerated fi bers. In view of this lower-value raw material, the yarns pro-duced on BT machines achieve very good quality re-sults and innovative customers manage to be very competitive. The new C 120 spin box maintains this know-how and in addition improves the quality of the yarns produced by means of new concepts and parts. The C 120 trash removal concept optimizes the opening zone and impurity discharge channels in such a way that maximum benefi ts are derived from the raw material. The waste content includes trash, short fi bers, naps and neps. The system guarantees maximum utilization of the material because the max imum number of impurities are eliminated, but not at the expense of good quality fi bers. Example: with cotton, 4,2 MIC, Ne 10, sliver trash 0,25%, spun at 100 000 rpm, waste eliminated from the yarn is 0,45% and contains hard particles, short fi bers, dust and neps. In the case of very clean raw materials and fi ner yarns of Ne 20-40, where the focus is on maximum cleanliness, the C 120 spin box eliminates the neces-sary hard particles and short fi bers. Example: with cotton, 3,57 MIC, Ne 30, sliver trash 0,10%, spun at 100 000 rpm, 0,20% waste is re-moved. Due to the machine concept we can operate these applications at speeds up to 110 000 rpm and up to 200 m/min delivery speed, and still maintain high effi ciency in trash removal, which results in im-proved CV values and fewer yarn imperfections.

ton weaving yarns to knitting yarns mainly involves changing the exit tube assembly, optionally also the rotor type with optimized groove. The switch from cotton to 100% viscose, acrylic, PES blends or other blends with man-made fi bers only requires changes to the opening roller. For 100% PES there is also a special nozzle. In general a variety of components are available for yarn features to meet customers‘ special needs.

Production fl exibility is further increased by the ability to produce completely diff erent materials on the machine at the same time. Independent machine drives, two conveyor belts and diff erent settings en-able very small batches to be produced quickly and economically. Batch changes or maintenance can be performed on one half of a machine while spinning continues on the other half, thus optimizing both operation and productivity.

CHANGES IN THE VALUE CHAIN. Today‘s textile val-ue chain is no longer production-driven, but rather consumption-driven, so that spinning and weaving mills are no longer leaders in trends and goods sup-ply. The total time to market has also become consid-erably shorter. The fl exibility of the BT 923 enables spinning mills to respond quickly to changes in demand.

FLEXIBILITY OF THE C 120 SPIN BOX. In addition to cotton yarns, their blends and regenerated fi bers, the C 120 spin box has also extended the typical appli-cation range to include knitting yarns, 100% rayon, PES and their blends. The most frequent spin box specifi cation for 80 000 - 110 000 rpm covers the majority of appli-cations. Special yarn features require minimal parts changes, and these are performed without tools or complicated assembly work. The switch from the cot-

COMFORO® – ACCESS TO A WIDE RANGE OF APPLI-CATIONS. In today‘s textile markets it comes down to securing positions that are increasingly distinc-tive from those of competitors. This calls for special-ist expertise over and above that in the spinning mill from fi ber to yarn. Rieter has established partnerships with leading, innovative fi ber manufacturers, downstream proces-sors and dyeing and fi nishing specialists. ComfoRo® makes this know-how on OE rotor-spun yarn accessi-ble to Rieter customers. In cooperation with its part-ners, who operate worldwide, numerous inquiries from customers on this subject have already been comprehensively answered. Furthermore, interest in improved and new end products has also been aroused.

ComfoRo® makes the advantages of R 40 OE rotor-spun yarn accessible for downstream processes and the end products.

COMFORO® – KNOW-HOW FOR OE ROTOR-SPUN YARN

COMFORO® KNOW-HOW FOR PRODUCT DEVELOP-MENT. For the advantages of the R 40 and OE rotor-spun yarn to be exploited in the spinning mill, the operators of downstream process stages must also be aware of these advantages. It is important to note in this context that OE rotor-spun yarns are basically diff erent in nature from ring-spun yarns. The familiar wrapper fi bers infl uence the surface structure as well as the high pilling resistance. It is therefore worthwhile, when using OE rotor-spun yarn, to re-optimize each of the process stages. The relevant know-how is provided in conjunction with the partners in the context of ComfoRo®. High-quality end products enjoying excellent acceptance in the marketplace are created in this way.

ADVANTAGES OF COMFORO® OE ROTOR-SPUN YARNS PRODUCED ON THE R 40. With AEROpiecing technol-ogy, Rieter off er a unique opportunity to produce yarns without disturbing piecings on the R 40. The high spinning stability and an innovative selection of spinning media enable adapted yarn structures to be produced with soft twist or high tenacity and defi ned hairiness. The productivity potential of the R 40 is enormous, with up to 400 spinning positions, deliv ery speeds of up to 350 m/min and rotor speeds of up to 160 000 rpm. Together with the minimized energy consumption it ensures the lowest possible costs at this process stage.

The ComfoRo® logo signals the additional benefi ts that Rieter customers can enjoy.

The manufacture of high-quality products from rotor-spun yarn can be further optimi-zed with the R 40 and ComfoRo®.

20 Rieter . LINK 48 . 2/2006

SUCCESSFUL EXAMPLES OF COMFORO® ARE TOWE-LING AND T-SHIRTS. The advantages of ComfoRo® can be demonstrated impressively in these two clas-sical application segments for OE rotor-spun yarn. Ne 17 weaving yarns are manufactured at up to 200 m/min for the ground warp of cotton terry tow-els. Ne 12 weft yarns permit a delivery speed of 210 m/min with a 33 mm rotor diameter. Softer twisted yarns are then produced with a special rotor groove for the pile warp. With an optimum structure of the woven fabric, the structure of the OE rotor-spun yarn ensures a high-quality, uniform surface in the fi n -ish ed product. Our partners in downstream opera-tions have the relevant know-how. OE rotor-spun yarns are also demonstrating their advantages worldwide in single jersey knitted fab-rics, such as classical T-shirts. The very good uni-formity of the OE rotor-spun yarns means that in particular the thick places in the knits are substan-tially reduced compared to ring-spun yarns. The sig-nifi cant economic advantages result from the high production speed of the spinning process, the use of inexpensive raw materials and the reduced ma-chine downtimes in downstream processing. The R 40 spins a typical Ne 28 cotton knitting yarn at up to 180 m/min, and an end product of good quality is also obtained with a medium-quality cotton. One of our ComfoRo® partners has utilized new products for fi nishing the knitted fabric, with outstanding re-sults. These fi ndings are available to our customers via ComfoRo®.

THE SYSTEM IS THE KEY TO SUCCESS. As a sys-tems supplier, Rieter has technological and eco-nomic know-how covering the entire process. With ComfoRo®, Rieter off ers its customers more than yarn. Cooperation with specialists throughout the textile chain is the key to success.

QUALITY FROM THE YARN TO THE END PRODUCT. Yarns produced on the R 40 are very much in de-mand on the market. Their problem-free take-off behavior in weaving and knitting is well known. The simple design and precise operation of the R 40 wind-ing unit with the latest drive technology has proved its qualities for outstanding package build-up. The electronically controlled yarn traverse gear facili-tates rapid changeover from soft dyeing packages to dense weaving packages. Package width can be ide-ally adapted to yarn count. The cross over angle can be adjusted in 1° steps. Maximum package weights of up to 6 kg are possible with a package diameter of up to 350 mm. These properties, plus the precisely adjustable yarn take-off length and the absence of faults, also enable downtimes to be minimized in downstream processing. These advantages of the R 40 are gaining an extensive foothold for all kinds of knitted fabrics, denim and especially also for spinning viscose.

A new, innovative wax ring signals when exactly the right time has come to replace it. This saves costs and ensures uninterrupted application of wax.

GUEST

THE WAX RINGTHAT CUTS COSTS

soon, wax is wasted. On the other hand, if the ring is replaced too late, this can result in uneven applica-tion of wax to the yarn and thus to an uneven coeffi -cient of friction of the yarn, or even yarn without any application of wax, which will inevitably cause proc-essing problems in knitting operations. But when is the right time to replace the ring? The ideal residual height of the wax ring is 6 mm. How-ever, this is diffi cult to estimate visually on the ma-chine, especially if an employee has to supervise and operate several machines. Reseda Binder has adopted an innovative approach to this problem: intelligent signaling is innovatively and simply integrated in the wax ring. Five holes are cast in the underside of the ring. The holes are arranged in such a way that at least one hole is always in the visible zone of the Rieter waxing system.

The latest innovation by the Reseda Binder company is a wax ring with Waste Watcher®. Reseda Binder has patented this invention worldwide and is thus the only manufacturer that can supply „intelligent“ wax rings.

DECIDING ON THE RIGHT MOMENT IS IMPORTANT AND DIFFICULT. The problems are well known: it is a matter of replacing the wax ring at the right time. Since the wax rings in the waxing systems on the ma-chines are partly concealed, they cannot be clear-ly seen by personnel. It is therefore diffi cult to see how high, i.e. thick, the wax ring still is and whether it needs to be replaced. If the ring is replaced too

Fig. 1 The new wax ring with a height of 45 mm displays no holes and can remain in use. If the wax is worn down to the ideal residual height, 5 holes are visible. This is the ideal time to replace it.

Machine effi ciency is also improved by utilizing the maximum wax running time. The thickness of the ring can be checked without having to provoke a thread breakage. Unnecessary opening of the waxing system is avoid-ed, and its durability is prolonged.

MILL OPERATIONS ILLUSTRATE THE MAJOR ADVAN-TAGES. Fig. 2 shows the annual wax consumption of two customers, with and without Waste Watcher®: both spinning mills were able to reduce their annu-al consumption of wax by 30-40%. This shows that switching to Reseda Binder‘s new, innovative Waste Watcher® wax rings pays off for every spinning mill. The calculation is simple.

No holes are therefore visible in a new wax ring. How ever, when the ring has been worn down to 6 mm, fi ve holes become visible – a clear sign for operating personnel that the wax ring now needs to be replaced (Fig. 1).

THE ADVANTAGES OF THIS APPROACH ARE OBVI-OUS. The Waste Watcher® will be of advantage to every spinning mill: every single wax ring can be used to its minimum thickness. The rings will now be replaced at the ideal time, rather than too early. This enables spinning mills to reduce wax consumption considerably and cut costs. At the same time they can be sure that uniform wax-ing takes place throughout the running period, and uneven waxing - or even no waxing - is avoided. This prevents complaints from customers.

ERBEL & RIETER – A STRONG TEAM IN TURKEY

THE ERBEL SUCCESS STORY. Haluk Erbel began to work as an agent for Rieter Machine Works Ltd. as long ago as 1974. In 1983 he established a two-man company under his own management. He had al ready recognized at that time that an agent has to off er more than just machines, and he added after-sales service facilities to his company‘s off ering. ERBEL now provides the Turkish textile industry with sales, spare parts and service off erings from bases in Istanbul and Adana. These are provided by more than 40 employees, including 10 textile and mechan-ical engineers. ERBEL represents Rieter Textile Systems in Turkey for the short staple spinning, fi lament yarn manufac-turing and nonwovens sectors. In addition to Rieter, ERBEL also represents other leading manufacturers of spinning equipment. More than 50% of the short staple spinning ma-chines operating in Turkey were supplied by Rieter. Rieter and ERBEL are proud to have earned such con-fi dence from their customers. They thus help the lo-cal economy to add value in processing Turkish cot-ton into top-quality yarns and thus assure the Turkish textile industry of access to the European markets. Excellent installation support and after-sales serv-ice are provided by Rieter Textile Machinery Trade and Service Ltd., headed by Franz Caduff , from its Istanbul base. The service team consists of 38 tech-nicians and engineers.

RIETER‘S FACE IN TURKEY. Haluk Erbel is actively involved in setting up the ITM trade fair and has a strong network of relationships with the ITM organi-zation and with Turkish textile magazines and insti-tutions. Asked about the secret of his success, Haluk Erbel replies: „Our work focuses on our customers, we cooperate closely with our customers, explain our advantages clearly, discuss various fi nancing options, and if problems arise, we respond immedi-ately and work out solutions together with Rieter to keep our customers satisfi ed.“

Turkey is one of the world‘s major textile centers and in June 2006 will once again be the meeting place for textile manufacturers for all over the globe. Rieter‘s agent ERBEL MÜMESSILLIK A.S. will show innova-tive machines and comprehensive service off erings at ITM 2006.
