Relation Between GSM and Yarn Count for

Different fabrics

Introduction:Yarn Count:

Count is a numerical value, which express the coarseness or fineness (diameter) of the yarn and also indicate the relationship between length and weight(the mass per unit length or the length per unit mass)of that yarn.

GSM: 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. GSM means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. By this we can compare the fabrics in unit area which is heavier and which is lighter.
