The main reason for generation of hairy yarn in the twisting zone of ring frame is
Show Hint
To reduce hairiness, modern "compact spinning" systems use pneumatic suction to condense the fiber strand, ensuring all leading ends are tucked in before twisting occurs.

- rear end of fibre is not gripped
- both the ends of fibre are not gripped
- leading end of the fibre is not gripped
- both the ends of fibre are gripped

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
• Identify the main reason for hairy yarn in the twisting zone of a ring frame.
Step 2: Detailed Explanation:
• In the twisting zone, fibres leaving the front rollers are held by the roller nip at one end and by the twisted yarn body at the other.
• Fibres whose rear end is not gripped by the front rollers (a free trailing end) are not bound into the yarn and protrude as hairs.
Step 3: Final Answer:
The correct option is (A) rear end of fibre is not gripped.
• Identify the main reason for hairy yarn in the twisting zone of a ring frame.
Step 2: Detailed Explanation:
• In the twisting zone, fibres leaving the front rollers are held by the roller nip at one end and by the twisted yarn body at the other.
• Fibres whose rear end is not gripped by the front rollers (a free trailing end) are not bound into the yarn and protrude as hairs.
Step 3: Final Answer:
The correct option is (A) rear end of fibre is not gripped.

- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The yarn strength depends on the level of twist given in the final stage of ring spinning. Reason (R): Twist helps in binding the fibres through lateral pressure exerted by outer layers of fibres on the fibres in the core. In the light of the above statements, choose the most appropriate answer from the options given below:
- During yarn formation on the ring frame, the cotton material passes through:
A. back roller
B. ring bobbin
C. delivery roller
D. traveller
E. lappet guide Choose the correct answer from the options given below :
