Effect of Wrong Sewing Needle Selection in Apparel Industry

Selection of Sewing Needle in Apparel Industry:

In the readymade garments industry, sewing needles should be selected according to the types of fabric and sewing thread. Perfect needle selection helps to achieve better output from the sewing section. The size of the needle is expressed differently by the manufacturers but the metric size is the simplest and widely used in the garments manufacturing sector. In shortly, needle size is denoted by Nm and is expressed by measuring the diameter of the middle of the needle blade.

Effect of Wrong Needle Selection in Garments Industry:

Various effects of wrong needle selection in the apparel industry have mentioned below:

1. Effects when the needle is finer than sewing thread,
2. Effects when the thread is finer than a needle,
3. Effects when the needle is coarser than required fabric,
4. Effects when the needle is finer than the required fabric.

All the above effects have explained in the following:

1. Effects when the needle is finer than sewing thread:

When the needle is finer than sewing thread then the thread cannot move easily through the needle eye and the thread will not take position accurately at the needle long groove. As a result, more heat will generate on the needle for higher friction which ultimately results in thread breakage and garments production loss.

2. Effects when the thread is finer than needle:

When the thread is finer than the needle then it may produce a slipped stitch as the needle can’t create the perfect size of the loop.

3. Effects when the needle is coarser than required fabric:

When the needle is coarser than the required fabric then the fabric will be looked odd due to the larger hole. Here, seam puckering may produce on woven fabric.

4. Effects when the needle is finer than required fabric:

When the needle is finer than the required fabric then the needle will deflect and become curve with the action of the throat plate.  This type of curve needle will produce a slip stitch as the looper may not catch the loop needle thread.
