The chemical molecules of the polypropylene yarn are also very different, and it is made of polypropylene fibers. Polypropylene has good heat resistance, and the article can be read at a temperature of 100 ° C, and 150 ° C is not deformed under conditions without external force. The embrittlement temperature is -35 ° C, which is embarrained below -35 ° C, and cold resistance is not as good as polyethylene. The report value of the polypropylene glass transition has a 18qc, 0qc, 5 ° C, etc., which is also due to the use of different samples, wherein the crystalline phase is different from the amorphous phase, so that the amorphous portion is different in the molecular chain. Cause. The melting temperature of the polypropylene is increased by about 40 first 50, and the degree of degree of polypropylene melting point is 176 ° C from about 164 1 170 ° C, 100, and the like.

     It is relatively stable to other various chemical reagents, but the low molecular weight of aliphatic hydrocarbons, aromatic hydrocarbons, and hydrocarbons such as polypropylene, and its chemical stability increases with the increase in crystallinity, so Polypropylene is suitable for the production of various chemical pipes and accessories, and the anti-corrosion resistance is good. It is because there are so many good a little, and the effect of polypropylene yarn is more and more, the market is getting bigger and bigger. Introduction to the formation of polypropylene yarn, let us start from it. The advantage is that the texture is light, and polypropylene yarn density is only 0.91 g / cm3 is a common variety of density in chemical fibers, so the same weight of polypropylene can be higher than the higher coverage area of other fibers. The strength of strong polypropylene is high, the strength is large, the initial modulus is high, and the elasticity is excellent.

Fujian Jinquan Chemical Fiber Products Co., Ltd. was founded in 2011 and is located in the "brand capital" Jinjiang, which is convenient, 7 km from Jinjiang International Airport. The company is now covered by about 30 mu, with a building area of about 20000m2. It is a professional enterprise specializing in R & D, production and sales of polypropylene filaments.

Our company has a polypropylene FDY production line 20 and several supporting equipment. It mainly produces 300D-1200D polypropylene regeneration yarn, polypropylene color yarn, and gauze in polypropylene, with an annual output value of about 7,000 tons. Jinquan chemical fiber adheres to the spirit of Jinjiang people to win, and has developed anti-aging, anti-ultraviolet, antibacterial, antistatic, anti-flame retardant functional fibers.
