About the introduction of PP yarn, we first start from the advantages of PP yarn, light texture, its density of only 0.91g/cm3 is the lightest variety of common chemical fibers, so the same weight of polypropylene than other fibers to get a higher coverage area. The tensile polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. So the wear resistance of polypropylene is good; In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables; Hygroscopicity and dyeability, light quality and good heat preservation; Almost no moisture absorption, but the core absorption ability is very strong, moisture absorption and sweating effect is obvious; The hygroscopic property of polypropylene is very small, almost non-hygroscopic, and the moisture regain rate under general atmospheric conditions is close to zero. In addition, the electrical insulation of polypropylene is good, but it is easy to produce static electricity during processing. Because the thermal conductivity of polypropylene is small, the heating property is good; High strength polypropylene filament strength is second only to nylon, but the price is only 1/3 of nylon; The size of the fabric is stable, the wear resistance and elasticity are good, and the chemical stability is good.

The chemical molecules of PP yarn are also very different, and are made of polypropylene fibers. Polypropylene has good heat resistance, products can be disinfected and sterilized at temperatures above 100 ° C, under the condition of no external force, 150 ° C is not deformed. The embrittlement temperature is -35℃, and embrittlement will occur below -35℃, and the cold resistance is not as good as polyethylene. The reported values for the glass transition temperature of polypropylene are 18qC, 0qC, 5℃, etc., which is also because people use different samples, which contain different proportions of crystalline phase and amorphous phase, so that the amorphous part of the molecular chain chain length is different. The melting temperature of polypropylene is about 40-50% higher than that of polyethylene, about 164-170 ° C, and the melting point of 100% isotactic polypropylene is 176 ° C. The chemical stability of polypropylene is very good, in addition to being eroded by concentrated sulfuric acid, concentrated nitric acid, other chemical agents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make polypropylene soften and swell, while its chemical stability with the increase of crystallinity and improve, so polypropylene is suitable for making a variety of chemical pipes and accessories, anti-corrosion effect is good. It is because there are so many good advantages that the role of PP yarn is more and more, and the market is getting larger and larger.

Jinjiang Deke Textile Co., Ltd. was founded in 2011, located in "brand capital" Jinjiang, convenient transportation, 7 kilometers away from Jinjiang International Airport. The company now covers an area of about 30 acres, construction area of about 20000m2, is a professional engaged in research and development, production and sales of polypropylene filament enterprises.

Our company has 20 polypropylene FDY production lines and a number of supporting equipment. It mainly produces 300D-1200D polypropylene recycled yarn, polypropylene colored yarn, and polypropylene hollow yarn, with an annual output value of about 7,000 tons. Deke Textile adhering to the Jinjiang people love to fight to win the spirit, has developed a variety of colors of anti-aging, anti-ultraviolet, antibacterial, anti-static, anti-flame retardant functional fibers.
