At present, the main products suitable for friction spinning process are mainly coarse yarn and extra coarse yarn. The following products are the most ideal representatives.
1. Yarn for framework of friction sealing material with high strength, heat insulation, flame retardant, wear resistance and other functions. Such as aramid core spun yarn, composite yarn with metal wire, acrylic core spun yarn, aramid high temperature filter yarn, etc. This kind of yarn is often used in industrial products, such as all kinds of clutch panel framework materials, advanced brake belt base cloth, heat insulation packing, flame retardant conveyor belt, cutting gloves, etc. Its raw materials are generally functional fibers which are difficult to control in traditional spinning mode, such as glass fiber, aramid fiber, carbon fiber and so on.
2. Spiral wound liquid filter yarn with good bulk and density. Such as friction spinning polypropylene filter yarn, because of its unique outer winding structure, the wound filter element not only has high filtering accuracy, but also has large flow. It is favored by users. Other products such as friction spinning absorbent cotton filter yarn, friction spinning glass fiber high temperature resistant filter yarn also have their own characteristics, and the products have high added value.
3. Waste spinning engineering products. In Wenzhou and other places in Zhejiang Province, smart businesses have developed various kinds of fiber scraps into clean mop yarn and mop towel yarn with distinctive characteristics through friction spinning machine, and the products are very popular. Meanwhile, the steel wire rope, wire, cable core yarn and other products spun from leftovers not only achieve waste utilization, but also create extremely considerable economic benefits.
