The characteristics of polypropylene
I plant Qingdao polyester line Xiaobian to introduce the characteristics of polypropylene
The name of the Chinese goods in the production of synthetic fibers, such as raw materials, made of propylene as raw materials for the use of the by-product of petroleum refining. Also known as polypropylene fiber.
According to the 2013 and 2018 China polypropylene fiber industry competition pattern and development trend research report data shows, the future polypropylene fiber downstream industry will enter a new round of cycles which brings polypropylene fiber market demand expansion, polypropylene fiber industry sales rebounded significantly, supply-demand relationship has improved, the profitability of the industry steadily. At the same time, under the guiding principle of the national "Twelfth Five Year Plan" and the adjustment of industrial structure, polypropylene fiber facing tremendous market opportunity for investment, the industry is expected to usher in a new development opportunity.
The name of the Chinese goods in the production of synthetic fibers, such as raw materials, made of propylene as raw materials for the use of the by-product of petroleum refining. Also known as polypropylene fiber. Rich raw materials, production process is simple, the product price is relatively lower than other synthetic fiber. The physical and mechanical properties of the fibers were characterized by high strength (4 to 6 g / day, 5 to 8 g / day), wet strength and dry strength of the basic same, small proportion (0.91), wear resistance, etc.. World polypropylene fiber annual output of more than 1000000 tons in 1980.
It is made from propylene as raw material and melt spinning. PP started industrial production in 1957, is a synthetic fiber in the bright younger generation. Because of the polypropylene fiber has the advantages of simple production process, cheap products, high strength, relative density and light advantages, so polypropylene development soon. The PP has fourth major varieties of synthetic fiber, is a common chemical fiber in the lightest fiber.
Polypropylene production including short fiber, filament and split fiber etc.. Polypropylene fiber membrane is polypropylene into the first film, then on the film stretching, make it split into fibrils formed by the mesh of.
