Mixing

The Selected cotton should be thoroughly

mixed to get a homogeneous mixing

One load Bale is 60 Bale.

One Bale weight is 250 kg.

Approximately15 Minutes taken to

unload one single bale.

Blow Room

The highly compressed bales received from

cotton field, should be opened thoroughly and the

embedded trash in the cotton should be beaten up

to clean the cotton to prepare it for subsequent

process.

Blow Room Processes are:

Bale Opener

Deo Cleaner

Step Scanner

Krishna Beater

Bale Opener

Bale Opener Machine is the first major

machine in blowroom line for ring spinning.

Function of Bale Opener Machine:

Regulating motion by swing paddle.

Air suctioning.

Beating action.

Spiked lattice action.

Deo Cleaner

The Main function of Deo cleaner is

to remove the impurities like

seeds,threads,irons present in the

cotton bale.

Step Scanner

The Step cleaner is to refine the

cotton material that comes after the

Deo cleaning process.

Krishna beater

To comb and extract the lighter

impurities from cotton.

Carding

Carding is also the major cleaning machine in which

the blow room lap is converted into cylindrical shape

sliver form.

Here, the fibers in the lap were individualized and

clean the fibers by removing foreign matters (trash) as

waste.

The foreign matter consists mainly of sand, dust, seed

coat frogmen's, leafy matters in the case of cotton and

of fused fibers, chips in the case of man-made fibers

(synthetics).

It removes the naps present in the lap.

Combined cleaning efficiency of carding and blow

room will be in average 93 to 96%.

Two workers have managing to 10 machines.

Drawing

The cotton is next processed by the DRAWING

FRAME.

It is a machine in which several strands of SILVER

are combined into one strand and DRAWN OUT, so

that the combined strands approximate the weight

and size of any one of the original strands.

2 Processes done in Drawing

Breaker

Finisher

Eight silver cotton is mixed to get one silver cotton.

[08 Input Boxes & 01 Output Box]

Simplex

The diameter of the drawing sliver is reduced

sufficiently before final spinning of yarn.

The delivered material is roving for continuous

strand of fibers twisted slightly before it is wound

on bobbins for the next processes.

One simplex Bobbins is produced in 2.30 hours.

5 Simplex machines available.

For a Single Process,

124 simplex Bobbins are produced by 2

Machines.

96 simplex Bobbins are produced by 2

Machines another 3 machines.

Spinning

This is the final stage where actual yarn is

manufactured.

The Objective of spinning is:

1. To draw out the roving being fed to the ring

frame to the decided degree or fineness.

2. To impart sufficient twist to the emerging strand

of fibers and from continuous yarn.

3. To wind up the spun yarn into some convenient

package from.

Totally 25 spinning machines available.

Each machine produces 440 cop’s in 5 Hours.

Winding

Prepared yarn cops in spinning will be converted

into a cone for Packaging.

It is a process of transferring yarn or thread from

one type of package to another type by applying cone

winding and cheese winding.

One cone is produced within 2.30 hours.

4 machines available.

For a single process,

One machines produces 160 cones.

Another 3 machine produces 120 cones.

Cone model is same but it varies with weight.

One cone weight is 1.25kg or 1.5kg(End Users)

One Bale weight is 50 kg

40 Cone =0ne Bale

Boiling

The main purpose of Boiling is to Remove Twisted Thread/Yarn, Neps.

The Products coming from Winding Section is stored in a Trolley and then the trolley

is inserted into Seiger Boiler Machine.

The Boiling process done in two rounds

1. First the Temperature set as 60 degree and the Vacuum Pressure as -630 degree

Centigrade and its boiled duration of 5 minutes

2. Next the Temperature has been increased to 70 degree and Vacuum Pressure as

-580 degree Centigrade with the duration of 20 minutes.

Before After

Reeling

Reeling is the process where the silk that has

been wound into skeins, is cleaned, receives a

twist and is wound onto bobbins

Budding

Product checking using UV

UV (Ultra-Violet) Checking is made for the

each one of the finished Product from Cone

Winding, Boiler Section before Packaging.

The Purpose of UV Checking is to find out

the incorrect product i.e., Two (or) more

Different Types of Threads used in Single

Product.

After this Checking, the Correct Product is

entered into Packing Section.

Packing

Cones prepared in Auto Cone section are

transferred to finish good Store Room.

These Cones are packed in polythene bags and

shipped according to customer’s specifications.

Normal Packing

1 Bag= 40 Cones= 50kg

Quality Checking

System Name : USTER HVI Spectrum

Function : It measures the Cotton Length,

Strength, Neps & Color Grade

Quality Checking - Report

Quality Checking

System Name : USTER AFIS (Advanced fiber

inforamation system )

Function : It predicts the neps which is come

from the Carding Section [Carding Wired Life].

Quality Checking

System Name : USTER Tester 4

Function : It checks the Uniformity of Yarn in terms of thin,

thick ,neps and haireness (H)

It is done by Three Stages.

i.Conveyor

ii.Sensor CS used for finding thin & thickness of

Yarn.

iii.Sensor OH used for finding the neps &

haireness

Quality Checking

System Name : USTER TENSOJET4

Function : It measures the Single Yarn Strength

and Elongation of Yarn
