There are various types of fabric is available in the market, they are woven, knitted or non-woven fabric. Fabrics are differing from one to another depending on the manufacturing techniques. Fabrics are differing depending on the fabric design. Some fabrics are heavy and some are light in weight. So, it is important to determine the fabric weight.
Types of Fabric Weight Measurement System and Their Application: Fabric weight can be measured by the following three ways. They are as follow:
By using formula: Fabric weight can be measured by the formula. Where fabric length, weight and width is known. In this measuring system it is not required to cut the fabric. But it needs to measure the whole fabric. Two formula is given below:
Oz/yd2 = 576 M/ (LW)
Oz/yd = 16 M/L
M= Mass of the fabric roll in Ibs
L= Length in yards
W= Width in inch
By GSM cutter: GSM means Grams per Square Meter. It is most used methods for measuring fabric weight. In these methods, GSM cutter, cutting pad and electric balance is used. It is a quick and authentic method. For measure this above instruments and small amount of fabric sample is required.
By using fabric consumption: Another process is done by using fabric consumption. By these methods, fabric weight can be measurement without any measurement and instruments. Here, fabric consumption is used for calculating the fabric weight directly. The main problem is that, warp and weft crimps are required which varies widely and only an approximate value is used which may not provide exact GSM of the ultimate fabric.
Among the above three methods, GSM cutter system is more comfortable and accurate methods for measure the fabric weight. These methods are used for test the fabric weight in various types of quality testing lab.
