Polypropylene staple fiber, fibrous yarn with wool. Short, spun into the long fiber of polypropylene, fiber length, the formation of yarn smooth, so the long fiber fiber than the short fiber breaking strength and high permeability. Made of polypropylene staple fiber made of industrial cloth, cloth with powder without filtering the market and the pressure filter effect than long fiber. The polypropylene fiber made of industrial fabrics, smooth cloth, breathable performance, suitable for powder filtration. In addition, I developed the company's new 858-type polyester fabric (industrial), chemical and pharmaceutical companies are the best filter material but not suitable for powder filtration. Polypropylene staple fiber 4212 industrial cloth, is my company specifically for the dye factory developed filter material, it is 2X2 polypropylene staple fiber through the twist weaving twill made of industrial cloth. We infer the material from the user's opinion, and thus the trial of the 4212 # products. Because it is resistant to high strength, breathable performance is higher than the polyester 120-17 4 times higher, alkali resistance, good acid resistance, fabric hair, so that greatly increase the filter effect, to prevent the residue blocked cloth hole affect the filter. The service life of the corresponding than vinylon and other industrial fabrics 10 times higher.
