Polypropylene FDY yarn is a kind of yarn, after investigation, the application of polypropylene FDY yarn in the market more than Danny stop. The use of polypropylene FDY wire has brought a lot of convenience to our work and has also become an important member of our work. With the technological advancement of spinning grade polypropylene and spinning technology, the annual output of polypropylene FDY yarn accounts for the proportion of chemical fiber Higher and higher, more and more attention in the world chemical fiber development.

There are many types of chemical fiber used in textile, polypropylene FDY silk is one of them, then what material is it, what is the difference between it and traditional chemical fiber? Let us work together to understand the coat material it applies. Here are some of the materials we have compiled for everyone in Ningbo Volkswagen Industries.


Polypropylene FDY silk varieties


  The varieties of polypropylene filaments, including non-deformed filaments and bulge deformed filaments, short fibers, bristles, split membrane, hollow fibers, shaped fibers, all kinds of composite fibers and non-woven fabrics.


Use of polypropylene FDY wire


  The main purpose is the production of carpet (including carpet and suede), decorative cloth, furniture cloth, all kinds of ropes, tapes, fishing nets, linoleum, building reinforcements, packaging materials and industrial fabrics such as filter cloth, Wait. In addition, the application of clothing is also increasingly widespread, with a variety of fiber blends made of different types of blended fabrics, after knitting can be made into shirts, outerwear, sportswear, socks and so on. Made of polypropylene fiber hollow fiber, light, warm, good elasticity. Polypropylene industrial filter polypropylene in the macromolecular structure does not contain chemical groups can be combined with the dye, so dyeing more difficult. Scientific name Polypropylene fiber, near the flame that is melted, flammable, away from the fire burning slowly and black smoke, yellow flame on the bottom, the bottom of the blue, exudes a smell of oil, after burning ash as hard yellowish brown particles, hand twist fragile . Usually melt-color method, the pigment preparation and polypropylene polymer in the screw extruder evenly mixed, after melt spinning to get color fastness to color fiber. Another method is acrylic acid, acrylonitrile, vinyl pyridine copolymerization or graft copolymerization, the polymer macromolecules can be combined with the dye polar groups, and then directly using conventional dyeing. In the polypropylene production process often need to add a variety of additives to improve dyeing, light and fire resistance.

Polypropylene FDY yarn can be applied to all aspects of life, but also can become a general thread, rope, webbing alternatives. Because of the excellent performance of polypropylene FDY silk, light weight, wear resistance, high breaking strength, and low prices. The above on the content of polypropylene FDY silk, if you still do not know a friend, you can consult Ningbo Volkswagen Industrial!
