Question 76 (Textile Engineering & Fibre Science)

Fabric thickness in mm will be nearly

(A)0.22
(B)0.33
(C)0.44
(D)0.55
[Show Answer]

Warp count=30s Ne

Weft count=35s Ne

Ends per cm=35

Picks per cm=30

Warp crimp=6.5%

Weft crimp=13%

Cotton fibre density=1.52 gm/cm3

Fabric thickness(t)=h1+d1

Where d1=warp dia

d1=0.0166 cm (As calculated in qsn no 75)

h1=crimp height

h_1=\frac{136 \times \sqrt warp crimp}{ppi} \times \frac{1}{1000} inch

h_1=\frac{136 \times \sqrt 6.5}{30} \times \frac{1}{1000} cm

h_1=\frac{136 \times 2.55}{30} \times \frac{1}{1000} cm

h_1=0.116 cm

Now,
Fabric thickness(t)=0.116+0.0166
