 Polyester fiber is a high-quality synthetic fiber, which is used to make thread with high strength. It ranks second among various types of threads, next to nylon thread. Moreover, it does not reduce in strength when wet. Its shrinkage rate is very small, and after proper shaping, the shrinkage is less than 1%, so the stitched thread can maintain a flat and beautiful appearance without wrinkling. Its wear resistance ranks second to nylon. It has a low moisture recovery rate, good resistance to high and low temperatures, light resistance, and water resistance. Therefore, polyester thread is a widely used variety, replacing cotton sewing thread in many situations. Polyester thread is widely used, suitable for sewing cotton, chemical fiber, and blended fabrics, and also suitable for sewing knitted outerwear. Special polyester thread is also an excellent thread for the shoe and hat leather industry.
