Relation Among Yarn Count, Machine Gauge & Fabric GSM

Machine Gauge
Selection of machine gauge depends upon yarn diameter. Yarn diameter also depends on several factors such as yarn count, fiber type, yarn twist, yarn finishing, etc.

Yarn Count
The count is a numerical value, which expresses the coarseness or fineness (diameter) of the yarn. And also indicates the relationship between length and weight (the mass per unit length or the length per unit mass) of that yarn.

Fabric GSM
The GSM of fabric is one kind of specification of fabric that 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 the unit area which are heavier and which is lighter.
It is the metric measurement to check the weight of the fabric. GSM value is dependent on the kind of fabric – Cotton, wool, polyester, etc. The fabric GSM is directly proportional to the thickness of the fabric. As the value of gsm increases, the thickness increases as well. GSM is not restricted to fabric alone. To calculate the GSM of fabric or paper means to measure their thickness.
