“Determination
of GSM of supplied woven & knitted fabric”
Ò Details of the
experiment:
Determination
of GSM of supplied woven & knitted fabric is the weight of 1 meter in gram.
Ò Testing atmosphere: The atmosphere
is not commercially created. It’s a normal lab where the approximate
temperature is 20 c and the relative humidity is approximately 65%. In the lab
the light was quite good for testing the experiment.
Ò Tools: The tools are:
·
A Woven & Knitted fabric.
·
A round cutter.
·
An Electronic Balance.
Ò Procedure: The
procedure of counting GSM is very easy. First of with normal tension we have to
cut two pieces of fabric both woven and knit. Then we have to weight those
fabrics. Then with the help of equation we will get the result.

Ò Calculation: The
calculation of this experiment is quite easy. To calculate the GSM we just have
to calculate 1 meter from 100 cm. Then we just have to calculate the average.
Ò Results: The
result is the fabrics we marked GSM are;
§ 55.48
g/meter in woven.
§ 279
g/meter in knit.
Ò Precaution: The main precaution in this process is
to maintain the standard tension of the fabric. If it changed the experiment
will not be perfect.
Ò Conclusion: There
is nothing tough in this testing. But everyone should concern about those
precautions and the atmosphere. I had faced no problem while doing the
experiment.
