Polypropylene multifilament yarn is a type of synthetic yarn made from polypropylene polymer. It is a highly versatile and durable material that is commonly used in the textile industry for a wide range of applications.

The yarn is made up of multiple small fibers, or filaments, that are twisted or spun together to form a single strand. Polypropylene multifilament yarn is known for its strength, abrasion resistance, and moisture resistance, which make it ideal for use in outdoor and industrial applications.

Some common uses of polypropylene multifilament yarn include ropes, twines, cords, webbing, and geotextiles.
