Polypropylene high-strength yarn is used more and more with the development of the company, and polypropylene high-strength yarn is a fine and long polymer material used in construction engineering. Its aspect ratio is generally 100. Above, and has a certain tensile strength, modulus of elasticity and ultimate elongation.
Moreover, polypropylene fiber is a synthetic fiber which is widely used in concrete engineering and has a wide range of use. This is due to the excellent physical and mechanical properties of polypropylene fibers and excellent chemical stability such as acid and alkali resistance, and the sources of raw materials are wide, the production technology is not complicated, and the price is relatively low.
Furthermore, polypropylene fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, polyamide fibers, polyester fibers and the like are commonly classified by engineering synthetic polypropylene fibers. The polypropylene fiber is a fiber obtained by polymerizing propylene into an isotactic 97% to 98% polypropylene resin and then melt-extruding. Therefore, the application of polypropylene high-strength yarn in life has become more and more extensive.
