Question 29 (Textile Engineering & Fibre Science)

A loom is producing 2 m wide grey fabric with 8% weft crimp. Assuming that the loom is running at 570 rpm with 90% efficiency, the weft consumption in kg/hr of 30 text yarn will be _______________

Answer / Solution

Given in the question–
Count of yarn=30 tex
width of the fabric=2 m

Weft crimp=8%

Loom rpm=570 rpm

Efficiency=90%

Weft consumption(kg/hr)=?

Formula–

Weft consumption(kg/hr)=tex of yarn x width of fabric x loom speed x efficiency(%) x (1-(weft crimp%/100)) x 60/10⁸

Weft consumption(kg/hr)=30 x 2 x 570 x 90 x (1-(8/100)) x 60/10⁸

Weft consumption(kg/hr)=30 x 2 x 570 x 90 x (1-0.08) x 60/10⁸

Weft consumption(kg/hr)=30 x 2 x 570 x 90 x (0.92) x 60/10⁸

Weft consumption(kg/hr)=169905600/100000000

Weft consumption(kg/hr)=1.70 (Answer)
