How to Calculate Fabric GSM Using GSM Cutter?
Fabric GSM plays an important role in the garments manufacturing sector. As a garments merchandiser, everyone has to know about the fabric GSM calculation method. It should be noted here that, fabric GSM can be calculated by using a GSM cutter or sometimes without using a GSM cutter. Here, I have presented the fabric GSM calculation method by using the GSM cutter and another one (GSM calculation method without using GSM cutter) has discussed in my previous article.
What is GSM?
The meaning of GSM is “gram per square meter”, which unit is (gm/m2).
What is GSM Cutter?
GSM cutter is a circular cutter. GSM cutter cuts 1/100 of a square meter of fabric area.
GSM Calculation Method Using GSM Cutter:
The GSM calculation method using the GSM cutter is not the same as we have followed during the GSM calculation method without using the GSM cutter. Here, we should follow the below steps:
- Firstly, you have to cut 5pcs swatches by sing GSM cutter from the different parts of fabrics.
- Now, Measure the weight of each cutting swatches with the help of weighing balance in one by one method.
- Calculate the average weight of cutting swatches.
- Now, by multiplying “average cutting swatch weight” with 100, we can easily get the actual fabric’s GSM.
Note: Area of round GSM cutter is (1/100) m2
Now, one example is enough to clear the above discussion which has been given in the following.
5 pcs cutting swatches weights are 1.2gm, 1.4gm, 1.3gm, 1.1gm, and 1.5gm respectively.
The average weight of cutting swatch,
In this situation, we have to multiply the average cutting swatch weight by 100 to get the actual fabric’s GSM.
Fabric’s GSM = Average cutting swatch weight × 100
= 1.3 × 100
So, fabric’s GSM by using GSM cutter is 130
