Fabric Weight:
Fabric weight is the most important characteristic of the fabric. It is one of the ways in which fabrics are classified. Fabric weights are measured in a few different ways. Generally, the fabric weight is measured by weighing a standardized width of a yard or meter on a scale. Fabric weights are also occasionally determined by weighing square yards of quality, or by weighing yards per one pound. The weight of the one-yard or meter is recorded in ounces or grams and the fabric is then classified by its weight. The weight of textiles is measured in ounces in the U.S. and in Asia and is measured in grams in Europe. For measuring fabric weight in large quantity industry follow the GSM technique. In this article, we will know about, how to calculate fabric weight calculation.
How to Calculate Fabric Weight Calculation
Fabric Weight Calculation:
…………………………………………….EPI X PPI
Fabric specification = ……………………………………….. X Fabric width
………………………………….Warp count X Weft count
Or,
…………………………………Warp count X Weft count
Fabric specification = ………………………………………… X Fabric width
……………………………………………EPI X PPI
Problem:
…………………………………10 X 8
Fabric specification = ……….…… X 60”. Calculate the fabric weight of 1000m.
………………………………..70 X 50
Solution:
EPI = 70 and warp count = 10
Total no of warp = 70 X 60 = 4200
Length of each end = 1000m + 1000 X 3% [3% crimp]
= 1030m
Total length of warp = 4200 X 1030
= 4326000m
Now, we know
…………L X w
Ne = ……………
…………W X l
……………..4200 X 1030 X 0.4536
Or, 10 = …………………………………….
…………………..W X 840 X 0.91
……………..4200 X 1030 X 0.4536
Or, W = …………………………………..
………………..10 X 840 X 0.91
Or, 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% [As Crimp 5%]
= 63”
= 1.6m
Total length of weft = 50 X 39.37 X 1000 X 1.6 m
Again,
…………L X w
Ne = …………….
…………W X l
…………….50 X 39.37 X 1000 X 1.6
Or, 8 = ……………………………………….
………………….W X 840 X 0.91
……………..50 X 39.37 X 1000 X 1.6
Or, W = ……………………………………….
…………………..8 X 840 X 0.91
Or, W = 233.62 kg
Total fabric weight = 256.71 + 233.62 kg
= 490.33 kg (ANS)
