The presentation is on the basis of visiting a spinning mills . It is normally for textile engineering's student. One can easily get a concept for industrial visit. Before a mill visit this presentation should see.

17. CARDING PROCESS
• Main Parts:
: The region from lap roller up to
cylinder is known as taker-in.
: The cylinder get opened with sharp
teeth and then pass over to doffer.
: The doffer take the cleaned cotton.

Doubling: The process of combing two or more
sliver rovings or yarns into one is called doubling.
Drawing: It is a process of yarn manufacturing in
which the sliver is elongated when passing through
pairs of rollers, each pair faster than the previous
one.

21. > To straighten the fibers in the slivers.
> To make them lie is a manner parallel to their neighbours
and to the sliver axis.
> To improve the uniformity and evenness of the slivers.
> To reduce weight per unit length of sliver.
> To reduce irregularities of fibre by doubling and drafting.
> To remove dust from sliver.
> To make perfect blending of the sliver.
22. QUALITY SECTION & LAB
Quality Control:
The process or processes used in the
production of single yarns or of fabrics
generated directly from polymer.
23. QUALITY SECTION & LAB
• Quality of raw material can be defined in
various terms :
1. Transcendent
2. Product based
3. User based
4. Manufacturing based
5. Value based
24. QUALITY SECTION & LAB
YarnTesting:
100% cotton samples in the form of bale or opened and cleaned
material (card mat).
Measurements
Micronaire (Micro Grams Per Inch)
Measured by relating airflow resistance to the specific
surface of fibers.
1 -------------- 3.1 Very fine
3.1 -------------- 3.9 fine
4.0 -------------- 4.9 medium
Above 6 Coarser
33. Asia composite LTD is a self-sufficient factory with all
the necessary utilities. It has water treatment plant to
clean the water before using in the factory. The mills
three gas-burn generators guarantee uninterrupted
power supply for 24 hours a day to all of the
operations in the factory.
34. OPINION• Visiting in Asia composite LTD was an excellent experience for our
group. There we were learned practically the yarn manufacturing
process from first to last step. And also knew about the machines
used in yarn manufacturing process. There was suitable
environment need for a spinning mill. But being disappointed to see
that there were many worker who have no educational
qualification, but they are managing many kinds of machine which
is harmful for both industry & themselves. And another matter is
that they had not given us any information about their waste
management system. We think the spinning mill authority should
choose their worker with having educational qualification and
having knowledge about spinning mill. And also train the worker
before they start working.
After all it can be said that Asia composite LTD have some
lacking's,but if we keep these lacking's aside then it is the best
spinning mill for a textile related person specially for a textile engineer.
