Spinning

What is Spinning?

The Spinning is a technological system in which twist is inserted to the fibers and yarn is produced. The spinning process includes many processes which transforms the bales of raw cotton into a yarn ready for weaving. The term "spinning" can refer to the whole activity or just to the final process of making the yarn. The raw cotton arrives in the form of large bales. These are broken open and a worker feeds the cotton into a machine called a "breaker" which gets rid of some of the dirt. The cotton may not be consistent in quality from bale to bale therefore samples are taken before getting bales in best quality.

Following processes are involved in manufacturing of yarn.

Mixing

Mixing of cotton brought to make a uniform blend in order to make a uniform yarn with high quality parameter in order to avoid any shade problem. For this purpose, the number of bales are mixed to get uniform results. Raw cotton is purchased from best cotton growing areas of country and also cotton bales are imported from foreign countries. For stocking and mixing, sandwich-mixing technique is used.

Back Process.

Back process of yarn manufacturing process is contributed by following sections.

a. Blow Room Section
b. Carding Section
c. Drawing Section
d. Combing Section
e. Simplex (Roving formation)

a) Blow Room

In the Blow room section cotton is opened and cleaned through the following machines.

1. Auto Bale Plucker
2. Single Roller Cleaner Machine "B11"
3. Chute Feed System
4. Loptex (Contamination Control System)

b) Carding.

In this section cotton is opened cleaned and formed slivers of particular thickness. Each unit of Hussain Group has one of the best carding machines in the world. Following machines are used in this process

1. Crosrol MK 5D
2. Trutzchler DK 903

c) Drawing Section

In the Drawing section sliver is doubled, blended and drafted to parallel all fiber and to control and straighten the hooks present in cotton to form a uniform & even sliver for production of high quality yarn of very low CV%.

Hussain Group has following machine which are used in this process.

1) DX7A Toyoda Japan as Breaker drawing
2) RSBD 30 and RSBD 30C as Finisher Drawing

d) Combing Section.

In this section, 20% excessive waste (comber noil) is extracted. In this process, latest machinery Reiter E 62 (Swiss) is used which is very high quality performance machine.

e) Simplex Section.

In simplex section, sliver is fed and roving is produced. Finisher sliver is drafted and very low twist is inserted to form Roving. Roving is final preparatory shape of yarn in Back process stage, which will be converted into yarn in ring department.

Yarn Production Process

Ring is process where yarn is manufactured with clear specification of count and other specifications after Roving is creeled on ring machine from Simplex department. This roving is drafted and twisted to form yarn.
