Question 46 (Textile Engineering & Fibre Science)

The limit irregularity of a 200 denier yarn spun from this blend is

(A)10.55
(B)12.55
(C)11.55
(D)14.55
[Show Answer]

From the dia of fibre Y,we can assume that this wool.

So,

For wool blend-

CV_lim=\frac{118.8}{\sqrt n}

n= number fibres in the yarn cross-section

n=Denier of blend yarn/Avg denier of fibre

n=200/3

n=66.67

CV_lim=\frac{118.8}{\sqrt 66.67}

CV_lim=\frac{118.8}{8.16}

CV_lim=14.55
