GSM is short form of “Gram Per Square
Meter”. GSM is the weight in gram per
square meter in fabric. GSM is a very important parameter of specified a
certain quality of knitted fabric. The production calculated in “Weight” for knitting.
GSM Cutter is very popular & easy usable instrument in all knit factory. But,
now we learn How to be calculating Fabric GSM without GSM Cutter.
Suppose,
We have 4*2
Yds fabric which that weight is 2 Kg.
So, we know,
1 inch =
2.54 cm
36 inch =
36*2.54 = 91.44 cm
2 yards =
91.44 * 2 = 182.88 cm / 100 = 1.8288 mm
4 yards =
91.44 * 4 = 365.76 cm / 100 = 3.6576 mm
Total Area =
4 yards * 2 yards = 1.8288 * 3.6676 = 6.68901888 m2
Now, 2 kg =
2 * 1000 gm = 2000 gm
So,
6.68901888 m2 = 2000 gm
GSM = 2000 /
6.68901888 = 298.997 ~ 299
