Question 65 (Textile Engineering & Fibre Science)
When denier of a fibre is doubled, its diameter increases by
Option B is correct.
Given in the question-
Initial denier of fibre(D1)=D
Then, final denier of fibre(D2)=2D
Its diameter increased by=?
Dia is directly proportional to the square root of the denier of fibre.
Increase in fibre diameter=1.41 times (Ans)
