Sewing Thread Inspection

Factors should be considered for sewing thread inspection are:

A. Thread construction/ Ticket number.

Test for thread construction:

Ø Thread count

Ø Thread ply

Ø Number of twist.

Ø Thread balance

Ø Thread tenacity

Ø Thread elongation

B. Sewing ability: the ability of a thread to be sewn is called sewing ability. To determine the sewing ability of a thread, the running performance is counted. The ability of sewn in highest and fault free sewn in normal condition. Some requirement is necessary for good sewing;

Ø Imperfection: The yarn breakage is occurred frequently when the knot or slub is present in sewing thread; for this the efficiency of machine and production is less and the quality is so low.

Ø Finish: Finishing means using lubricant which helps to pass the needle eye through the guide. The amount of lubricant is 3% to 15%. The amount of lubricant should be same in all package of the lot.

Ø Color: the color of thread should be same in all parts of the sample as well as the whole lot otherwise it may cause reverse effect on the fabric.

Ø Package density:to maintain the proper tension the package density should be same in all package or cone .

Ø Winding:the winding of sewing thread should be uniform otherwise brakage may be high and it has the direct effect over the garments.
