Cutting marks by scissors:
The fabric is cut at two places as shown in the figure. The distance between both the cut should be as large as possible. The distance should also be measurable by the measuring scale.
Taking out threads from the swatch:
A definite number of threads are taken out from the swatch as shown in the figure. The number of threads is counted precisely. Any mistake can affect your results.
Measuring of thread's length:
When you can count the threads, one thread is taken out from the thread's bunch. Now we make this single thread straight with the help of a finger. We should always be careful during the straightening of the thread. There should not be any stretch in the thread during straightening.
Now we should measure this thread with the help of a measuring scale. Please don't forget to add this single thread in the thread's bunch. Please see the below figure.
Weighing of thread's bunch:
Now put this thread's bunch on the pan of the electronic weighing scale and record the weight of threads. Don't forget to see the zero reading of the weighing scale before weight measuring. If there is an error, do a re-zero of the scale reading and then measure the bunch weight. Please see the below figure.
