Difference between carded and combed yarn

Carded1. 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.

Combed1.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.

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.
