# 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 start for a calculation, it becomes possible to save time and ease the calculation. Let us clear fabric weight calculation by using the fabric specification 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.

### Important Fabric Specification for Fabric Weight Calculation

Mathematical problem:

……………………………….10 x 8
Fabric specification: ……………. X 60”
………………………………70 x 50

* Calculate the weight of 1000 meters?

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)
