1)It has the functions of high strength, heat insulation, flame retardant, wear resistance and so on. Such as aramid fiber core-coated yarn, composite yarn containing metal wire, acrylic composite core-coated yarn, aramid fiber high temperature filter yarn, etc. this kind of yarn is often used in industrial products, such as various clutch sheet frame materials, advanced brake lining base cloth, heat insulation packing, flame retardant conveyor belt, cutting-proof gloves and so on. 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)Winding liquid filter core yarn with good bulking and density. Such as friction spinning polypropylene filter yarn, because of its unique outer winding structure, the winding filter core not only has high filtering precision, but also has a large flow rate. It is deeply favored by users. Others such as friction spinning skim cotton cabin filter yarn and friction spinning glass fiber high temperature resistant cabin filter yarn also have their own characteristics, and the products have higher added value.

3)Waste spinning engineering products. Merchants have developed various fiber leftover bits and pieces into mop yarn, floor cleaning towel yarn and so on with distinctive characteristics through friction spinning machine, and the products are very popular. and products such as steel wire ropes, electric wires, cable core yarn, which are also woven with leftover bits and pieces, not only achieve the utilization of waste, but also create considerable economic benefits.
