Polüpropeenkiud

Polüpropeenkiud is a synthetic fiber made from polypropylene, a thermoplastic polymer. It is known for its strength, durability, and resistance to moisture, chemicals, and UV radiation. These properties make it a versatile material used in a wide range of applications.

The production of polüpropeenkiud involves melting polypropylene pellets and extruding them through a spinneret, which is a device with many fine holes. As the molten polymer emerges, it is cooled and solidified into continuous filaments. These filaments can then be cut into staple fibers or used as continuous filament yarns.

In the textile industry, polüpropeenkiud is used for carpets, upholstery, ropes, and non-woven fabrics. Its hydrophobic nature makes it ideal for applications where moisture resistance is important, such as in outdoor gear, medical textiles, and filtration media. The fiber's good tensile strength and abrasion resistance also contribute to its use in industrial textiles and geotextiles for civil engineering projects.

Polüpropeenkiud is also valued for its low density, making products made from it lightweight. It is relatively inexpensive to produce compared to some other synthetic fibers. While it has good thermal insulation properties, it has a relatively low melting point, which limits its use in high-temperature applications. It is also resistant to most acids and alkalis, but can be degraded by strong oxidizing agents.
