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 mutch difficult when you have very short length of yarn. You can't make a lea or skein of the yarn of definite length of yarn. If you have very short length of yarn say 4 - 5 metres, the accurate length measurement of this this yarn gets 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 find the yarn count of fabric swatch. This balance doesn't give accurate results. You can't determine the count of short yarn length. Now question arises 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 below steps:

Cutting marks by scissor:

The fabric is cut at two places as shown in the fugure. The distance between both the cut should be as large as possible. The distance should also be measurable by 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 are 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 thread's bunch.  Now we makes this single thread straight with the help of finger.  We should alway be careful during straightening of thread. There should not be any stretch in the thread during straightening.
Now we should measure this thread with the help of 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 electronic weighing scale and record the weight of threads. Don't forget to see the zero reading of weighing scale before weight measuring. If there is an error, do re - zero of the scale reading and then measure the bunch weight. Please se below figure..
