Question 52 (Textile Engineering & Fibre Science)
the direct twist factor of 35 Nm yarn is 36 tpcm.tex1/2 . The twist per inch of the yarn is approximately
(A) | 17 |
(B) | 19 |
(C) | 21 |
(D) | 23 |
[Show Answer]
Given in the question-
Yarn count=36 Nm
By relationship-
Nm=1.69Ne
36=1.69Ne
Ne=36/1.69
Ne=21.30
By relationship-
Tex=590.5/Ne
Tex=590.5/21.30
Tex=590.5/21.30
Tex=27.72
Twist per Inch(TPI)=?
By formula-
TPCM=6.83
1 inch=2.54 cm
TPI=6.83 x 2.54
TPI=17.34
or
TPI=17 (Ans)
