GATE (TF) Textile 2003 Question Paper Solution | GATE/2003/TF/44

A yarn is produced by blending two fibres X and Y whose particulars are given below

Fineness 2 denier 21 microns
Blend %5050
Question 44 (Textile Engineering & Fibre Science)

The denier of fibre Y is (take density of fibre Y as 1.3 g/cm3)

[Show Answer]

Option D is correct

Dia of the fibre Y=21 microns
d=21 \times  10^-4 cm

Denier=\frac{\pi}{4} \times d^2 \times density \times 9000 \times 100

Denier=\frac{3.14}{4} \times (21 \times 10^-4)^2 \times 1.3 \times 9000 \times 100

Denier of fibre Y=4.05 (Ans)
