The comprehensive index for evaluating the quality of polester sewing thread is seamlessness. 

Sewing performance shows that under specified conditions, sewing thread can smoothly sew and form good stitches, and maintain certain mechanical properties in stitches. The quality of sewability will directly affect the production efficiency, sewing quality and service performance of garments. According to the national standards, sewing threads are classified into first-class, second-class and second-class foreign products. In order to make the sewing thread have the best sewability in garment processing and the sewing effect is satisfactory, it is very important to select and apply the sewing thread correctly. 

The correct application of sewing thread should follow the following principles:

(1) Compatibility with fabric characteristics: Only when sewing thread is the same or similar to the material, can it ensure the unity of shrinkage, heat resistance, wear resistance and durability, and avoid the appearance shrinkage caused by the difference between thread and fabric.

(2) Consistent with the type of garment: For special purpose garments, special function sewing thread should be considered, such as elastic sewing thread for elastic garments and sewing thread for fire fighting garments through heat resistance, flame retardant and water proof.

(3). Coordinate with the stitch form: the stitches of different parts of garments are different. Sewing threads should also be changed accordingly. For example, the lines or deformation threads need to be used to expand the stitches. Double line stitches should be chosen with extended lines. The crotch seam and shoulder suture should be fastened, while the eyeliner should be wear-resistant.
