Consider the following components of a needle:
P. Shank
Q. Beard
R. Barb
S. Latch
The combination of correct components of a needle in a needle punching nonwoven machine is
Show Hint
Needle punching needles always contain barbs for fibre entanglement, while beard and latch structures belong to sewing and knitting needles respectively.
Step 1: Understanding the needle punching process.
A needle punching nonwoven machine uses specially designed needles that mechanically entangle fibres. The structure of these needles is different from knitting or sewing needles. They mainly contain parts that help penetrate, grip, and transport fibres during punching.
Step 2: Evaluating the components.
P. Shank – This is the upper part of the needle that fits into the bar or needle beam. It is present in needle punching needles.
Q. Beard – Found in sewing needles, not in needle punching needles.
R. Barb – These are small notches used to grab and entangle fibres during punching. They are characteristic of felting/needle punching needles.
S. Latch – This part belongs to latch needles used in knitting, not needle punching. Step 3: Conclusion.
Only Shank (P) and Barb (R) are actual parts of a needle punching needle. Thus, the correct combination is (D) P and R.
