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 different depending on the fabric design. Some fabrics are heavy and some are lighter in weight. So, it is very important to determine the fabric’s weight.
Types of fabric weight measuring system and their area of applications: Fabric weight can be measured by the following three ways. They are as follow:
By using the formula: Fabric weight can be measured by the formula. Where fabric length, weight, and width is known. In this measurement system, it is not required to cut the fabrics. 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 the most used methods for measuring fabric weight. In these methods, GSM cutter, cutting pad, and electric balance are used. It is a quick and authentic method. For measure, this above instruments and a small amount of fabric sample is required.
By using fabric consumption: Another process is done by using fabrics consumption rate. By these methods, fabric weight can be measured without any measurement and instruments. Here, fabric consumption is used for calculating the fabric’s 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, the GSM cutter system is more comfortable and accurate methods to measure the fabric weight. These methods are used to test the fabric weight in various types of the quality testing lab.
Fabric weight measurement is required in weaving, knitting, dyeing and finishing unit of the textile mills. It is an offline quality assurance system.
