Question 22 (Textile Engineering & Fibre Science)
The length (km) of 5 kg of 30 Ne yarn (rounded off to the nearest integer) is __253 to 255__.
Given in the question:
Weight of yarn=5 kg
Count of yarn=30s Ne
Length of the yarn=?
By definition of the tex-
weight of 1000 meter length=19.68 gram (tex=19.68)
i.e. 19.68 gram of yarn weight have=1000 meter length
1 gram of yarn weight have =1000/19.68
5000 gram of yarn weight have=1000*5000/19.68 meter length
Length of yarn=5000000/19.68
Length of yarn=254065.041/1000 km
Length of yarn=254.065 km (Answer)
