Weight ranges of woven fabrics


Fabric weight would be measured as the weight of the fabric in grams per m2. It does affect
the many of the fabric properties. Like drapability, breathability, durability, the way they fit,
fabric stiffness, rigidity, thickness and also thermal properties.
Fabric weight depends on the type of material used to produce it, maybe the weave type
being used, and also the thickness of the fibre. It means it would depend on the fiber type
also.
GSM is an important indicator as a metric measurement to check weight as how many grams
per square meter of the fabric. By this can get an idea about thick ness and the quality of the
fabric for specific usages. According to the GSM count, different type of fabrics has been
divided in to categories.
