Polyester sewing thread refers to the sewing thread produced from polyester.

Polyester fiber is a kind of high-quality synthetic fiber, which is used to produce high stitch strength. It is second only to nylon thread in all kinds of stitches, and it does not reduce strength in wet state. Its shrinkage rate is very small, and the shrinkage is less than 1% after proper setting, so the stitched stitches can always be flat and beautiful without shrinkage. Wear resistance is second only to nylon. Low moisture regain, good high temperature resistance, low temperature resistance, light resistance and water resistance. Therefore, the polyester thread is an extremely widely used variety, and in many cases, it replaces the cotton sewing thread. Polyester thread is widely used for sewing garments of cotton fabrics, chemical fiber fabrics and blended fabrics, as well as for sewing knit garments. The special polyester thread is also an excellent line for the footwear and leather industry.
