No, polypropylene industrial yarn is polypropylene fiber.

Polyester fiber, a synthetic fiber obtained by spinning a polyester obtained by polycondensation of an organic dibasic acid and a glycol. The abbreviation PET fiber is the largest variety of synthetic fiber. In addition, its greatest advantages are good wrinkle resistance and shape retention, and high strength and elastic recovery. Its strong, durable, anti-wrinkle and anti-hot.

Polypropylene industrial yarn is a fiber obtained by polymerization and melt spinning of propylene as a raw material. Polypropylene officially began its industrial production in 1957 and is a rising star in synthetic fibers. Because the polypropylene industrial yarn has the advantages of simple production process, low cost, high strength, and relatively low density, the polypropylene industrial yarn has developed rapidly. Polypropylene is currently the fourth largest variety of synthetic fibers and the lightest of the most common chemical fibers.

Polypropylene production includes short fibers, filaments, and split fibers.
