The first process of textile
industry is spinning process. The raw material of this process is cotton and the
output of this process is yarn. Several types of processes are related to this process,
that’s why this process is a complicated process.
According to types of finish, yarn
can divided into four. Such as-
- Combed Yarn
- Carded Yarn
- Rotor Yarn
- Slav yarn
And by the types of raw material yarn can be divided into-
·
100%
cotton yarn.
- CVC yarn. CVC- chief value of cotton. Percentage of cotton and polyester are basically 65 and 35 or 60 and 40 respectively. Most of the time it depends upon the buyer requirement.
- 100% polyester yarn.
- PC yarn. PC- Polyester cotton. Here percentage of polyester is more than cotton.
- 100% Viscose yarn.
Except these many more kinds of yarn
are producing in this textile world. Such as gray mélange( blending of cotton
and viscose),Bamboo yarn, Organic
cotton yarn etc.

Properties of combed yarn:
•Combed yarn is produced by excluding of
short yarns
• More fine and regular
• Higher breaking strength.
• More lustrous
• Naps percentages is almost zero.
• Less hairy
• Higher quality of yarn
The unit of yarn is count. Counts
Indicates the thickness of yarn. More the count finer the yarn is. Yarn price also
Increases according to increased by count number.
Common yarn count:
- 20 count
- 22 count
- 24 count
- 26 count
- 28 count
- 30 count
- 32 count
- 34 count
- 36 count
