Question 19 (Textile Engineering & Fibre Science)
Length of 20 tex polyester / cotton yarn in km on a 20 kg cone will be equal to
| (A) | 50 |
| (B) | 100 |
| (C) | 150 |
| (D) | 200 |
[Show Answer]
Given-
Count of polyester/cotton yarn=20 tex
Weight of cone=20kg
=20000 gm
Length of yarn(km)=?
By definition of tex-
1000 m length have…..=20 gm weight
i.e.
20gm weight yarns have=1000 m length
So,
20000 gm weight have….=1000 x 20000/20
Length of yarn=1000000 meter
Length of yarn=1000 km
