### YARN COUNT DETERMINATION FROM FABRIC SWATCH OR YARN COUNT DETERMINATION FROM SHORT LENGTH OF YARN

YARN COUNT DETERMINATION FROM SHORT LENGTH OF YARN OR DETERMINE THE YARN COUNT FROM FABRIC SWATCH:

The yarn count determination job gets much difficult when you have a very short length of yarn. You can't make a lea or skein of the yarn of a definite length of yarn. If you have a very short length of yarn say 4 - 5 metres, the accurate length measurement of this yarn gets a little difficult.

If you have a fabric swatch and don't have continuous yarn length then you face difficulties during yarn count determination.

The Beesley balance gets used to finding the yarn count of the fabric swatch. This balance doesn't give accurate results. You can't determine the count of short yarn length. Now the question arises on how to determine the count of yarn of fabric swatch or short length of yarn available. We are describing the simple and effective methods of determination of yarn which may be applied in both cases. The yarn count  determination process gets completed in the below steps:

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.

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 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.
