Fabric Weight Test
There are various types of fabric is available in the market such as woven, knitted, or non-woven fabric. Fabrics are differing from one to another depending on the manufacturing techniques. Fabrics are also different depending on the fabric design. Therefore, some fabrics are heavy and some are lighter in weight. So, it is important to determine the fabric weight.
Types of Fabric Weight Test Systems and Their Application:
Fabric weight can be measured in the following three ways. They are as follows:
- By Using Formula
- Using GSM Cutter
- By Fabric Consumption
Fabric Weight Measurement By Using Formula
Firstly, fabric weight can be measured by the formula where fabric length, weight, and width are known. In this measuring system, it is not required to cut the fabric but it needs to measure the whole fabric. There is two formula for fabric weight measurement. They are-
- Oz/yd2 = 576 M/ (LW)
- Oz/yd = 16 M/L
Where,
- M= Mass of the fabric roll in Ibs
- L= Length in yards
- W= Width in inch
Fabric Weight Test By GSM Cutter
Secondly, the gsm cutter uses to measure fabric weight. Basically, GSM means Grams per Square Meter. However, it is the most used method for measuring fabric weight. In these methods, a GSM cutter, cutting pad, and electric balance are used when it is a quick and authentic method. To measure with the above instruments and small amount of fabric sample is required.
Fabric Weight Test By Using Fabric Consumption
Another process is done by using fabric consumption. By these methods, fabric weight can be measured without any measurement or 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 the exact GSM of the ultimate fabric.
Among the above three methods, the GSM cutter system is a more comfortable and accurate method for measuring fabric weight. These methods are used to test the fabric weight in various types of quality testing lab.
In sum, fabric weight measurement is required in the weaving, knitting, dyeing, and finishing unit of a textile mill. It is an offline quality assurance system.
