GSM means grams per square meter of a knit, woven or non woven fabric. It is essential to know the weight of the fabric before manufacturing and after getting the finished fabric. It needs to measure the weight of the fabric to be sure about the finished weight of the fabric. This test can be carried out in different ways but it is very easy to know the weight of the fabric by cutting the fabric with the GSM cutter.
Taking the sample of fabric from bulk and conditioning for 4.30 to 06 hours
Taking the conditioning fabric for test on the G.S.M. cutter pad so that no crease or crinkle is formed.
Cutting the fabric with G.S.M. cutter (GSM Cutter Diameter 11.2 cm)
Taking the weight of the cut fabric (Length & Width 11.2 cm) in balance and multiply with 100.
Get the GSM of the fabric in oz/yard²
Measure the GSM of the Fabric by GSM Cutter:
It is one type of physical test of the fabric which is known as off line quality assurance system. By the following way we can measure the weight of the fabric.
- Cut the fabric with the GSM cutter (gram per square inch).
- Weight the fabric with the electric balance.
- The cut sample is 100 sq.cm. The weight of the cut sample is multiplied by 100.
- The result is the GSM of that particular fabric.
The weight of the fabric is 2.51 gm. That means the GSM of the fabric is 251. Because when we cut the fabric with the GSM cutter then we get 1 from the 100 meter from the 1 square meters.
