Combing Process

Combing Machine

For getting high quality of yarn, one extra process is introduced which is called combing process.Combing is an operation in which dirt and short fibers are removed from sliver lap by following ways.

• In a specially designed jaws, a narrow lap of fiber is firmly gripped across its width
• Closely spaced needles are passed through the fiber projecting from jaws.

Short fiber which we remove is called comber noil. The comber noil can be recycled in the production of carded yarn.Yarn which is get from comber sliver is called comber yarn. Carded sliver are combine into comber lap in a single continuous process stage. Flat sheet of fiber which is get from comber lap is fed into the comber in an intermediate.There are different ways by which value of combing is used in the manufacturing of cotton. By spinning point of view combing process makes more uniformity in the yarn. Strength of yarn is also high because in combing process short fiber are removed and only fiber having good strength remains. So it play very important role for increasing the yarn strength. Because of straightened condition of fibers combing makes possible spinning smoother and more lustrous yarn. In combing process length of fiber are strong so it need less twist produced then carded yarn.

Objectives of Combing

Following are the objectives of combing process:

1. To remove the fiber shorter than a predetermined length.
2. To remove remaining impurities in the comber lap.
3. To remove naps in the carded sliver.
4. To make the fiber more parallel and straight.
5. To produce a uniform sliver of required per unit length.
