Some Important Fabric Specification for Fabric Weight Calculation
What does fabric specification mean?
Fabric specification is one of the most important fundamental things in fabric weight calculation. It’s a kind of short form used in view of a long description. So that, when we starts for a calculation, it becomes possible to save time and easing the calculation. Let us clear this concept……
Warp count x weft count
Fabric specification = .......................................................
Ends per unit x picks per unit
Some most popular commercial fabrics with their specification:
30 x 30 tex
1. Jeans: .............................
36 x 26 per cm.
15/2 x 15/2 tex
2. Gabardine: .....................................
64 x 42 per cm.
20ˢ x 20ˢ
3. Denim: .........................
90 x60
14 x 16tex
4. Drill: ..........................
50 x 32per cm.
14/2 x 60tex
5. Poplin: ............................
60 x 14per cm.
33ˢ x 18ˢ
6. Sheeting: ...............................
18 x 18-24
27 x 38tex
7. Shirting: ..................................
22 x 26-8 per cm.
Mathematical problem:
10 x 8
Fabric specification: ……………. X 60”
70 x 50
Calculate the weight of 1000 meter?
Solution:
As we have known, fabric specification’s elaborate form
Warp count x weft count
Fabric specification = .......................................................
Ends per unit x picks per unit
So here, EPI = 70 and warp count = 10
Total no. of warp = 70 x 60 = 4200
Length of each end = 1000m + 1000 x 3% = 1030 m [crimp=3%]
Total length of warp = 4200 x 1030 = 4326000 m
L x w
Now, Ne =………………
W x l
4326000 x 0.4536
=> 10 = ……………………………
W x 840 x 0.91
4326000 x 0.4536
=> W = ………………………………
10 x 840 x 0.91
=>W = 256.71 kg
PPI = 50 and weft count = 8
Total no. of weft = 50 x 39.37 x 1000
Length of each weft = 60 + 60 x 5% = 63” = 1.6 m
Total length of weft = 50 x 39.37 x 1000 x 1.6
L x w
Now, Ne = ………………
W x l
50 x 39.37 x 1000 x 1.6
=> 10 = ………………………………
W x 840 x 0.91
=> W = 233.62 Kg
Total weight of the fabric = 233.62 + 256.7 = 490.33 kg (ANS)
