[0002] Polyester is an important variety of synthetic fiber and is the trade name of polyester fiber in my country. Polyester raw materials are the most resistant to friction, dry cleaning, stone washing, bleaching and other detergents among all materials. Its low elongation and low shrinkage rate ensure excellent sewability and can prevent wrinkles and skipped stitches. General polyester threads need to be cut during production. When the thread cutting machine in the prior art cuts the polyester thread, it is directly transmitted after cutting, but the thread mouth after cutting will become loose, thereby affecting the quality of the polyester thread.
