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)
