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.

PP yarn use:

Because polypropylene has many excellent properties and low cost, it has opened up a wide range of uses at home and abroad.

1. PP yarn is used for civilian use: it can be used as student clothing, elastic underwear, mosquito net, socks, blankets, wadding, padding and filling materials, textile fiber raw materials and their substitutes (household daily textiles; Curtains made of textiles or plastic.) Decorative materials, can be made curtains, sand release, carpet, bags, suspenders and so on.

2, PP yarn for medical health, can replace cotton yarn cloth, and has the advantage of non-stick wound.

3, PP yarn used in industry, can be made into ropes, Marine cables, fishing net industrial filter cloth, geotextile has been widely used in railways, highways, airports, tunnels, environmental protection and many other fields. Lifting belts, ropes, nets, tents and tarpaulins; Awnings, sails, sacks for the transport and storage of bulk materials made of textiles or synthetic fibres.

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.
