Question:
Wider setting between cylinder and flat results in higher:
Wider setting between cylinder and flat results in higher:
Show Hint
Tighter settings between carding elements (like cylinder and flat) enhance fibre cleaning but may increase the risk of fibre damage. Wider settings reduce fibre rupture but can increase nep formation.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the carding process.
In carding, the cylinder and flat work together to open and clean fibres. The setting between them influences the quality of the output sliver. Step 2: Effect of wider cylinder-flat setting.
When the gap (setting) between cylinder and flat is wider:
The control over short fibres and impurities reduces.
Fibre transfer between cylinder and flat becomes less effective.
As a result, impurities like seed coats and fibre clusters may not be removed properly.
Step 3: Impact on sliver.
Due to the ineffective cleaning, small fibre entanglements called neps are more likely to remain in the sliver. Hence, wider settings cause higher nep formation.
