polüpropüleenkiud

Polüpropüleenkiud, also known as polypropylene fiber, is a synthetic fiber produced from the thermoplastic polymer polypropylene. It is a versatile material widely used in various industries due to its favorable properties. Polypropylene is a hydrocarbon polymer, meaning it is primarily composed of carbon and hydrogen atoms. The extrusion process is typically used to create these fibers, where molten polypropylene is pushed through a spinneret and then cooled.

The characteristics of polypropylene fiber include excellent chemical resistance, making it resistant to most acids and alkalis. It also exhibits low moisture absorption, which contributes to its quick-drying nature and resistance to mildew and rot. Furthermore, polypropylene fibers are lightweight and have a high strength-to-weight ratio. They are also resistant to abrasion and UV degradation, although prolonged exposure to sunlight can weaken the fibers over time.

Common applications for polüpropüleenkiud include textiles, such as carpets, upholstery, and apparel, particularly activewear due to its moisture-wicking properties. It is also extensively used in industrial applications like geotextiles for soil stabilization and drainage, ropes, nets, and filtration media. In the construction industry, it is sometimes added to concrete to reduce cracking. Its non-toxic nature and ease of processing make it a cost-effective and environmentally friendly choice for many manufacturing processes.
