Polypropylene twisted yarn, also known as twisted PP yarn or plied yarn, is a type of synthetic yarn produced by twisting individual filaments or multiple strands together. This twisting process gives the yarn a specific twist direction and twist level, resulting in a rope‑like structure.

The main purpose of twisting is to improve cohesion between filaments, enhance yarn strength, and ensure better performance during downstream processing such as weaving and industrial manufacturing. Compared with untwisted yarn, polypropylene twisted yarn has better structural integrity and is less likely to fray or separate during use.

Polypropylene twisted yarn is made from polypropylene polymer through melt spinning followed by twisting. By adjusting the twist level, manufacturers can control the yarn’s strength, flexibility, and durability to meet various application requirements.

Thanks to its light weight, chemical resistance, and cost efficiency, polypropylene twisted yarn has become an important material in industrial textiles and technical applications.
