Polyester Sewing Thread

HOME > PRODUCTS > Sewing Thread > Polyester Sewing Thread
Polyester sewing thread is a type of thread for sewing made from polyester (polyethylene terephthalate, PET). It is a widely used sewing material in fields such as textile and apparel, home textiles, and industrial sewing. Produced by processing polyester fibers through processes like spinning and twisting, polyester itself is a synthetic fiber with characteristics including high strength, wear resistance, and good wrinkle resistance—all of which endow polyester sewing thread with excellent performance.

Materials

  • Polyester FDY
  • Polyester DTY
  • Nylon FDY
  • Nylon DTY

Features

  • High strength: Its breaking strength is superior to that of sewing threads made from natural fibers such as cotton thread. It is not easy to break during the sewing process, can withstand large tensile forces, and is suitable for sewing thicker or stiffer fabrics, such as denim and canvas.
  • Good wear resistance: The structure of polyester fiber makes it friction-resistant. During repeated sewing and use, the stitch is not easy to wear and break due to friction, which extends the service life of the sewn products.
  • Strong chemical resistance: It has good resistance to chemicals such as acids, alkalis, and detergents. When washed or in contact with chemicals, the performance of the thread is not easily affected, and problems such as discoloration and deterioration are less likely to occur.
  • Low shrinkage rate: Polyester has good stability, and the polyester sewing thread after treatment has a low shrinkage rate. The sewn clothes or products are not easy to deform due to the shrinkage of the thread after washing.
  • Good light resistance: Compared with cotton thread, it is not easy to age and become brittle under sunlight, making it suitable for outdoor products or sewn products that are often exposed to light.
