Question

In Needling, Kick up angle is related to

• A. Structured needle
• B. Needle with 9 barbs
• C. Needle beam
• D. Needle with 6 Barbs

Hint:

Kick-up angle is a machine setting controlled by needle beam alignment, not needle design.

Answer 1

The Correct Option is C

Concept: In needle punching machines used for nonwoven fabric production, the “kick-up angle” is an important geometric parameter that defines the inclination and movement behavior of the needle board during penetration into the fibrous web. It influences fiber entanglement efficiency, penetration depth, and fabric uniformity.

Step 1: Understand needling mechanism.
In needling, a needle board carrying hundreds of barbed needles moves vertically up and down to entangle fibers. The motion is controlled mechanically by the machine structure.

Step 2: Define kick-up angle.
Kick-up angle refers to the angular adjustment or inclination of the needle system which affects:
• Penetration direction
• Fiber drag and entanglement
• Stroke efficiency

Step 3: Identify controlling component.
This angle is not related to individual needle structure or barbs. Instead, it is governed by the mechanical arrangement of the needle beam, which holds and drives the needle board.

Step 4: Final conclusion.
Since the needle beam controls the angular movement and penetration geometry, kick-up angle is directly related to the needle beam. \[ \boxed{\text{Needle beam}} \] Thus, \[ \boxed{\text{Option (C) is correct.}} \]
