Yarn Count:

The yarn count is numerical expressions which define its coarseness or fineness. And also indicate the relationship between length and weight (the mass per unit length or the length per unit mass) of that yarn.

Fabric GSM:

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. The GSM of fabric is one kind of specification of fabric which is very important for a textile engineer for understanding and production of fabric. It is essential to know the weight of the fabric before manufacturing and after getting the finished fabric.
