Question 22 (Textile Technology & Fibre Science)
If the ratio of the linear densities (denier) of two circular fibers is 3, the corresponding ratio of their diameters, (rounded off to two decimal places), is ___1.70 to 1.75___.
[Show Answer]
write here
Formula:
d=4.44*10-3 cm
As given,ratio of linear densities of two circular fibres is 3 i.e. T1/T2=3
By formula dia of fibre is directly proportions to the square root of fibre linear density,
i.e. dT
i.e d1/d2=
so, d1/d2=,
Then, d1/d2=1.73 (Answer)
