CHAPTER 1:

TEXTILE INDUSTRY

INTRODUCTION

Textile: Meaning

The word textile mean for any artifact made by weaving or felting or

knitting or crocheting natural or synthetic fibers.

The textile industry (also known in the United Kingdom and

Australia as the Rag Trade) is a term used for industries primarily concerned with the

design or manufacture of clothing as well as the distribution and use of textiles.

Indian textile industry:

The Indian textile industry is one of the oldest and most significant

industries in the country. It accounts for around 4 per cent of the gross domestic product

(GDP), 14 per cent of industrial production and over 13 per cent of the country's total

export earnings. In fact, it is the largest foreign exchange earning sector in the country.

Moreover, it provides employment to over 35 million people.

The Indian textile industry is estimated to be around US$ 52 billion

and is likely to reach US$ 115 billion by 2012. The domestic market is likely to increase

from US$ 34.6 billion to US$ 60 billion by 2012. It is expected that India's share of

exports to the world would also increase from the current 4 per cent to around 7 per

cent during this period.

India's textile exports have shot up from US$ 19.14 billion in 2006-07

to US$ 22.13 billion in 2007-08, registering a growth of over 15 per cent.1

Key facts of Indian textile:

Indian Textile Industry is second largest industry in terms of providing vast

employment opportunities, employing around 35 million people in country after

agriculture sector and second largest after China, in terms of spindleage, and

has share of 23% of the world’s spindle capacity.

The Textile Industry plays vital role in economic development and contributes

14% to industrial production in the country, around 4% of GDP, 9% of excise

collections, 18% of employment in industrial sector, and has 16 % share in

country’s export.

Indian is the world’s third-largest producer of cotton and second-largest producer

of cotton yarns and textiles.

India is the largest exporter of yarn in the international market and has a share of

25% in world cotton yarn export market.

India contributes for 12% of the world’s production of textile fibers and yarn.

Including textiles and garments, 30% of India's export comes from this sector.

After the elimination of quota restrictions and implementation of National Textile

Policy 2000, it is estimated that the industry will grow with rapid rate and help to

strengthen the Indian economy.

I.S.O.

ISO ( INTERNATIONAL ORGANISATION FOR

STANDARDISATION )

Introduction

ISO is an independent organization which provides certificates to the firms / organizations

as the award of their better qualities as well as infrastructure.

This is an organization, which takes care of standardization of various systems all over the

world. It basically came into existence because the Europeans were the most quality

conscious class and demanded that the imports must have consistent quality. To assure

10

the quality product to the customers and consumers, there came into existence the quality

assurance mode.

It gives the award to a particular firm after observing the machinery, quality norms,

consumer satisfaction, mill’s environment, facility provided to employees, situation of

management & marketing areas.

In order to acquire the certification regarding ISO several rules and regulations are to be

fulfilled by the organization which is essential, provided by ISO in the form of elements. All

the records and internal audits regarding company is judged by ISO after every six month

so as to renewal the ISO certification. A group of members of ISO visit the organization

and it inspects all the assurance modals regarding ISO 9002 modals.

ISO 9001

Quality assurance in design, development, production, installation and

servicing. This model is stringent in the product design and after sales

service and can not deviate from the patterns.

ISO 9002

Quality control in production, installation and servicing. This model has an

imbibed flexibility in it, which assures that the producers can be lithe in

making their designs. The inspections so provided are at the elementary

shop-floor level.

11

Passage of Material:-

MIXING17

Fibres in required ratio are taken opened and blended in Blenders. During blending

water and antistatic agents are sprayed on fibres. In grey mixing tinting colors are also

mixed in the spraying solution to provide identification of the mixing, then material send

to bin room. This mixing is toppled once or twice to ensure proper blending of the fibres.

BLOW ROOM

The mixing is further opened so wastes like hard chips are removed from the mixing,

the tuft size is reduced and better blending of fibres is achieved. The mixing is

converted into lap to be fed into Cards. In new process Chute feed (Aero feed) system

the opened fibre is directly fed into Cards without lap formation.

A blowroom line is employed for:

1. Opening of base.

2. Cleaning of fibres.

3. Mixing of fibres.

4. For providing feed material for carding either as lap or though aerofeed.

CARDING

Carding is the Heart of the Spinning Mill. And well card is half spun.

Feeding by lap or in opened stage from chute the fibres are individualized, hard chips

short fibres and entanglements are removed in the form of droppings, fly and flat strip

respectively. The product of this is Card sliver.

Objects of Carding:

18

Fibre to fibre separation.

Removal of remaining trash of B/R process.

Individualization and partial parallelization of fibres.

Conversion of Lap or opened fibre into sliver.

19

DRAW FRAME

The Card sliver is subjected to doubling and drafting process to parallelize the fibres,

removes micro-dust and make a uniform sliver.

SPEED FRAME

The Draw frame sliver is drafted, slightly twisted and wound on bobbin, called roving.

20

RING FRAME

Spinning of roving into yarn of required count and twist is done here.

21

WINDING

Defect present in the spun yarn are cleared by Electronic Gauges and the cleared yarn is

wound on cones. The yarn is jointed by knots or spliced for getting a knotless yarn.

CHEESE WINDING

Two or more yarns as required for plying are wound parallels on cheeses.

22

DOUBLING

In doubling twist is imparted to the yarn wound on the cheeses. There are two processes.

(A) TFO: In this process twisting and winding on cones is done simultaneously to provide knot free yarn.

(B) RING DOUBLING: Here only twist is provided to the parallel wound yarn. This yarn is then wound on cones at Cone winding. At Cone winding the yarn is cleared of doubling defects.

PACKING

All cones after enough checking are packed in cartons or bags as per the established

packing process and sent to yarn godowns.

WASTES:

The wastes produced in spinning have been classified into:

1. Usable wastes

2. Unusable waste

During mixing 5% waste is added in yarn for domestic consumptions.

The usable waste is added during the mixing. It includes:-

1. Lap end

23

2. Card Sliver

3. Draw Frame Sliver

4. Roving

5. Bonda

CHAPTER 11:

Title of the Project:

“Sensors in textile industry”26

Sensors

– a device that detects/measures a signal or stimulus

– acquires information from the “real world”

One type of feedback frequently needed by industrial-control systems is the position of

one or more components of the operation being controlled. Sensors are devices used to

provide information on the presence or absence of an object.

Sensors include limit switches, photoelectric , inductive, capacitive, and ultrasonic

sensors. These products are packaged in various configurations to meet virtually any

27

requirement found in commercial and industrial applications. Each type of sensor will be

discussed in detail. At the end of the course an application guide is provided to help

determine the right sensor for a given application.

Technologies :

Limit switches use a mechanical actuator input, requiring the sensor to change its

output when an object is physically touching the switch. Sensors, such as photoelectric,

inductive, capacitive, and ultrasonic, change their output when an object is present, but

not touching the sensor. In addition to the advantages and disadvantages of each of

these sensor types, different sensor technologies are better suited for certain

applications. The following table lists the sensor technologies that will be discussed in

this course.

28

Contact Arrangement

Contacts are available in several configurations. They may be normally open (NO),

normally closed (NC), or a combination of normally open and normally closed contacts.

Circuit symbols are used to indicate an open or closed path of current flow. Contacts

are shown as normally open (NO) or normally closed (NC). The standard method of

showing a contact is by indicating the circuit condition it produces when the contact

actuating device is in the deenergized or nonoperated state. For the purpose of

explanation in this text a contact or device shown in a state opposite of its normal state29

will be highlighted. Highlighted symbols used to indicate the\ opposite state of a contact

or device are not legitimate symbols. They are used here for illustrative purposes only.

Mechanical limit switches, which will be covered in the next section, use a different set

of symbols. Highlighted symbols are used for illustrative purposes only.

Circuit Example :

In the following diagram a mechanical limit switch (LS1) has been placed in series with

a Run/Stop contact and the “M” contactor coil. The Run/Stop contact is in the Run

condition and the motor is running a process. This could be a conveyor or some other

device. Note that the “M” contacts and the “Run/ Stop” are shown highlighted, indicating

they are normally open contacts in the closed position. LS1 is a normally closed contact

30

of the mechanical limit switch.

When an object makes contact with the mechanical limit switch the LS1 contacts will

change state. In this example the normally closed contacts of LS1 open. The

mechanical limit switch symbol is highlighted. The “M” contactor coil is deenergized,

returning the normally open contacts of the “M” contactor to their normal position,

stopping the motor and the process.

34

One of Vetal's major products is the Vetal Scan Polysenso Integra, a cotton contamination

cleaning machine for colour and polypropylene. It is the successor to best selling VETAL

SCAN.

35

The most effective way of removing foreign particles like feather, color cloth bits

discolored threads, yellow fabric pieces by line Scan cameras and high density

impurities like white/transparent polypropylene, plastic, colored polythene bag

fragments using sonic acoustic / ultrasonic sensing. Detected materials are ejected

through high-speed nozzles by pneumatic air jets.

38

(Vetal Scan with Poly Sensor ) – Faq

1.What is the need?

Contamination in cotton has become a crucial factor along with production and quality.

Removal of contamination has matured into necessity considering the growing demand of

consumer, although safe practices are involved from cultivation to spinning there is much

need to control the level of contamination-cleaning machine has become a critical.

2. What is the Benefit?

a) Minimizing manual Labour   b) Possibility to match equal efficiency   c) Simple to

manage   d) improvement in consistency of removal

3. How many machines are required?

The Quantity of machines is a crucial question you need at least one machine between

each Blow Room line connected to cards. However improvement in cleaning is possible

with additional machines.

4.Does more machines lead to better clearing?

Certainly! More machines raise the chances of detection since scanning possibility is

increased.

5.What type of contamination it can detect?

The machine responds for White colorless polypropylene or synthetic materials. Colored

contamination like jute, lengthy thread etc.,

6.What is the ideal location for the machine to be installed?

The performance is better after a fine beater whose wide rectangular duct enhances the

separation of cotton in smaller tufts. The contamination that is exposed better offers

maximum clearing.

39

7.What is the distance required?

A minimum of 3750 mm is required between the machines to insert the Vetal scan. A

clearing Headroom height of 3440 mm is required.

8.How the contaminations are collected?

The contaminations ejected out by Air jets are transferred through a suction fan to a bag

along with few cotton lint.

9.What is the production throughput possible?

A production throughput of 1000 kgs is possible.

10.If the second machine has to be installed for improved clearing where it has to

located?

Many customers choose one more additional machine after the first cleaner. Even though

the cotton is not opened well at this point bigger contamination are detected earlier itself.

Here the machine can process 4 different assortments of cotton and change its

parameters on receiving a ‘Cotton flow Change’ information.

Working :

All the cotton is passed through the machine for scanning. Contaminations are exposed to

the cameras / sonic sensors for detection and Air jets for removal. Whenever

contaminations are detected it is effectively presented for elimination by Air jets.

Color sensors are designed to verify the presence of targets that can be differentiated by

color. These sensors project a modulated high intensity white light onto a target and

analyze the reflected light for its constituent RGB (red, green, blue) values. If the readings

of all of the three colors fall within the preprogrammed parameters, the sensor issues a

discrete signal that indicates a color match.

40

Basic Sensor Operation Procedure.1. First perform an external power on reset. Wait 10us for the reset sequence to be

completed.

2. Write sensor gain registers, CAP_RED, CAP_GREEN, CAP_BLUE and CAP_CLEAR

with values obtained from the previous sensor gain optimization procedure.

3. Write sensor gain registers, INT_RED, INT_GREEN, INT_BLUE and INT_CLEAR

with values obtained from the previous sensor gain optimization procedure.

4. Acquire offsets in normal operating environment. The light source for color sensing

must be turned off. The offsets are acquired by writing 02H to CTRL register. The

offset values are stored in offset data registers (address 72H, 73H, 74H, 75H). By

writing 01H to CONFIG register (address 01H), all digital values of the sensor will

automatically trim the offsets.

5. Now the sensor is ready to read colors. Sensor digital values can be acquired by

writing 01H to CTRL register (address 00H). Read CTRL register. When the value in

CTRL register is 00H, sensor digital values are acquired in sensor sample data

registers.

41

Dust & Metal Extraction Machine

( Electro Magnetic Detector)

Electro Magnetic Detector detects small metal impurities covered like broken nails, pins,

scrap, ring travelers etc., in traveling cotton and diverts them into a collection chamber

without disturbing the production much thereby reducing damage caused an spikes,

cleaning rollers and fire generation.

42

Metal Detection System

(Dust & Metal Extraction Machine) – Faq

Metal impurities can create havoc in a Spinning Mill by Damaging beaters, card wires etc.,

Generate Spark (Fire)

1. I have installed Magnets (Magnetic Elbows) in my mill. Is it sufficient?

Magnets covered certainly remove Metal impurities to some extent. With the advent of

Modern High Speed Blow rooms fitted with Automatic Bale Openers mostly pressed bales

are fed into the process. Here the metals travel along with the Cotton and mostly enclosed

by them.

MAGNETS DO NOT PICK UP METAL IMPURITIES COVERS INSIDE A BALL OF

COTTON. ELECTRONIC METAL DETECTORS ARE CAPABLE OF DETECTING METAL

IMPURITIES EVEN INSIDE COTTON.

2. How many Metal Detectors you require in a Blow room line?

One Metal Detection system will give good coverage.

3. Where it can be located?

It can be located immediately after the Bale openers.

4. Any Special requirement?

Yes You need a Straight-line piping distance of 8 meters after the opener. The Metal

Detector should have a safety distance of 1 meter diametrically, around which there

should not be any Metal objects present.

43

WORKING

Metal detector consists of a detector and pneumatic diverter fitted with a collection tank.

Metal impurities interrupt electromagnetic field generated inside the metal detector when

cotton flows through them. This signal is carried to the diverter when flap diverts the

cotton into a collection tank.

44

Fire Diversion System(Infrared sensors)

Spark detectors coverage of 360 degrees consisting of infra red sensors (camera) detects

ember in the pneumatically conveyed cotton/synthetic fibers inside ducts, trap them and

divert them to a Quenching tank through an extra suction motor (Ventilator fan) Coverage

for continuous, Infra Red, Automatic waste evacuation system, fiber compactors, filter

rooms.

45

Fire Diversion System (Dust & Fire Extraction Machine) - Faq

1.“I have not had a fire in my blow room in the last 10 years. Can I be confident that it will

not happen for next 10 years“

In tossing a Coin you have got 10 consecutive heads. What is the chance that the next

toss is going to be again heads? Only 50:50 It is a similar situation”

2. Where does it start?

Blow room consists of several openers, cleaners and storage machines, which are

interconnected through ducting materials, is pneumatically conveyed from one machine to

another. A small spark in the opening machines may (Bale plucker) develop into a huge

fire filling into each machine It may also start from a cleaner and cross over to the carding

section filling the chutes.

3. How many points should be better?

The more the better. There is no limitation. However, considering The Investment and

complexity it can vary from 2 to 5 per lines.

4. Which is the most fire prone part of a spinning mill?

BLOW ROOM is the most affected section in a Spinning mill. Waste collection and dust

collection systems are equally important.

46

5.Why Fire Diversion System is essential?

Today spinning mill are quality driven and production driven enterprise involving

sophisticated machineries meeting customer demands. While huge investment is made in

machineries building and process material it has become essential to safeguard to reduce

losses in emergence of fire and minimized downtime.

6. How does fire happen in a Spinning Mill?

The cause of fire may be the following:

Man made

Electrical short circuits

Process Fire

While man made fires are controlled adopting strict practices like good housekeeping

avoiding careless smoking, proper handling of hazardous substances. Electrical fires are

controlled by using approved equipments and accessories and involving properly trained

technicians. However process fires are inevitable since cotton or synthetic fires are highly

inflammable when it is passed through high speed machineries or automated lines or hard

substance may generate fire.

7. How can you interrupt?

With the Fire Diversion System you detect and trap the fired materials and drive out

through an extra suction fan.

8. Can it be 100% effective?

Frankly FDS is not a Fire Eliminator. Already Fire has happened at a point. Now the

primary objective is to react to it preventing it spreading further and take out the affected

material quickly.

47

Conclusion:

In conclusion, silicon is very suitable material for fabrication of smart sensors. But still a lot

of research is required to get benefits of the smart sensor, but from the experience of

already existing devices, we can expect that in the coming decade a large number of

successful smart sensors will emerge.
