The document provides an overview of textile engineering, focusing on the processes involved in yarn manufacturing, including spinning and the differences between carded and combed yarn. It describes various spinning techniques, flow charts for the production of jute yarn, and the ginning process that separates cotton fibers from seeds. The document aims to highlight the stages of textile production and the quality distinctions between types of yarn.

4. Spinning
The process of producing yarn or filament
from fibers or monomer respectively is
called spinning.

Yarn may be defined as a product of
substantial length and relationly small in
cross section consisting of fiberes or
filament with or without twist.

10. Difference between carded and
combed yarn
Carded
1. The yarn which is obtained
without combing is called
carded yarn.
2. The quality of carded yarn is
not better then combed
yarn.
3. Short fiber percentage is
high.
4. Combing action is not done
hare.
5.Less strength.
6. Irregular.
Combed
1.The yarn which is obtained
by combing is called
combed yarn.
2. The quality of combed yarn
is better than corded yarn.
3. Short fiber percentage is
low.
4. Combing action is done
hare.
5. Higher strength.
6. Regular.

11. Ginning: Ginning is process that separates the cotton
fiber from the seed.
Lint : Lint is a spinable fiber which is found the 1st
ginning
and there fiber length is 0.5-2.5”.
Linters : After ginning some short fiber are remained
with the surface of the cotton seed which is called linter.
Linters Uses : The linters are used as a raw material
for producing of rayon viscose rayon and acetate rayon.
