The relationship between Yarn Count and GSM Chart varies on the factors, for instance, the type of yarn used, the structure of weave and knit, and any kind of additional finishes applied to the fabric. So, based on this factor and different fabric types, this article covers the chart of yarn count and fabric GSM.
Table of Contents
What is Yarn Count?
Count means a numerical value. Yarn count means the expression of the yarn in a coarse and fine nature. It also indicates the length and weight of the relationship.
The weight is measured in the mass per unit length of the yarn.
What is Fabric GSM?
Fabric GSM (Gram per square meter) measures the fabric weight per unit area. It indicates the density and thickness of the fabric.
If the fabric GSM value ranges high, it means the fabric is thick and dense. Lower GSM simply means a light and thinner fabric.
Finding Yarn Count from Fabric GSM
If you are making a single jersey fabric but don’t know the fabric count, you can easily get an idea of the yarn counts from fabric GSM. For instance:
A single jersey fabric is 130 GSM. What would be its yarn count?
Answer: For Single Jersey Fabric,
4300/ GSM= Yarn Count, which means
4300/130= 33.08
Roughly you get an idea that this kind of fabric has a 32/34 yarn count
