Use of Air Nozzle in Ring Frame results in
Use of Air Nozzle in Ring Frame results in
Show Hint
Air nozzles in ring frame are mainly used to reduce yarn hairiness and improve surface quality.
Updated On: Jun 29, 2026
- Reduction in Hairs inch
- Higher Count CV%
- Lower Twist
- Higher Count
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
In ring spinning, air nozzles are used as an auxiliary yarn hairiness control system. The high-velocity air stream acts on the yarn surface and helps in binding loose fibre ends into the yarn structure. This reduces protruding fibres, thereby improving yarn smoothness and appearance.
Step 1: Understand function of air nozzle.
Air nozzle applies controlled air flow on running yarn. \[ \text{Air jet action} \Rightarrow \text{binding of surface fibres} \]
Step 2: Analyze effect on yarn properties.
It mainly affects surface characteristics:
• Reduces hairiness
• Improves compactness
• Enhances appearance \[ \text{Main effect: reduction in hairs/inch} \]
Step 3: Eliminate incorrect options.
• CV% → depends on drafting, not air nozzle
• Twist → controlled by spindle and draft
• Count → depends on drafting system
Step 4: Final answer.
\[ \boxed{\text{Reduction in Hairs / inch}} \] Thus, \[ \boxed{\text{Option (A) is correct.}} \]
