Question

Amongst the following, the machine(s) that remove(s) neps is/are:

• A. Comber
• B. Blowroom
• C. Roving frame
• D. Card

Hint:

In yarn preparation, a comber and card are essential for removing neps and improving fiber uniformity.

Answer 1

The Correct Option is A, D

Step 1: Comber.
The comber is specifically designed to remove short fibers and neps from cotton or other fibers during the preparation process for spinning. Step 2: Blowroom.
The blowroom does not directly remove neps but is involved in opening and cleaning fibers at the start of the yarn formation process. 
Step 3: Roving frame.
The roving frame is used for drafting the fibers, but it does not have the capability to remove neps. 
Step 4: Card.
The carding machine is capable of removing neps by separating and cleaning the fiber mass. It does so by combing and carding the fibers, which helps in eliminating neps.
