Q: -2- Calculating the Total yarn consumption for Required fabric 1,00,000 yards woven fabric of specification (16x12)/116x56, Width-56”- 100% Cotton, 3/1-twill fabric.
Solution:
Here,
Order Quantity = 1,00,000
yards
Grey Qty. = Order Quantity + Process Loss
(7%)
= 1,00,000 + (1,00,000 x 7%)
= 1,07,000 yards
Bim Length (B/L) = Grey Qty.
+ Wastage (14%)
= 1,07,000 + (1,07,000 x 14%)
=
1,21,980 yards
EPI = 116
PPI or, Fabric width = 56
Warp yarn count = 16
Weft yarn count = 12
Total Ends = EPI x Finished
Fabric
= 116 x (56+1)
= 6612
Reed Count
= EPI -12%, Or 10% [Crimp %
+ Wastage]
=
116 – (116 x 10%)
= 104.4
Reed Space = Total Ends ÷
Reed Count
= 6612 ÷ 104.4
= 63.33333.
