Polypropylene industrial silk refers to all polypropylene filaments other than clothing. Its production technology and use are obviously different from clothing fiber. Polypropylene industrial silk refers to all polypropylene filaments other than clothing. Its production technology and use are obviously different from clothing fiber. Through the selection of HIGH POLYMER and high SPECIFICATION polypropylene raw materials, starting from improving the degree of elongation and crystallinity of macromolecular chain, reasonable control of spinning, stretching and heat treatment process, polypropylene industrial silkor high strength polypropylene fiber can be obtained. Linear density, modulus, strength requirements are high, elongation at break and expansion rate requirements are generally low.
Characteristics of polypropylene industrial silk:
1. Shape: The longitudinal surface of polypropylene is flat and smooth, and the cross section is round.
2. Density: The biggest advantage of polypropylene is light texture, its density is only 0.91g/cm3 is the lightest variety of common chemical fiber density, so the same weight of polypropylene than other fibers to get a higher coverage area.
3. Strong extensibility: Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear well. In addition, the wet strength of polypropylene is almost equal to the dry strength, so it is an ideal material for making fishing nets and cables.
4. The hygroscopicity and dyeing polypropylene are very small, almost no hygroscopicity, and the moisture return rate is close to zero under general atmospheric conditions. But it has a core action, can transfer water vapor through the capillary in the fabric, but does not absorb any of its own. The dyeing property of polypropylene is poor and the chromatogram is not complete, but the method of stock solution coloring can be used to make up for the deficiency.
5. Acid and alkali resistant polypropylene has good chemical corrosion resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene acid and alkali resistance performance is good, so suitable for filtering materials and packaging materials.
6. Light resistance and other polypropylene light resistance is poor, thermal stability is also poor, easy to aging, not ironing. However, the anti-aging property can be improved by adding anti-aging agent during spinning.
Jiangyin Jinmeng Textile Co., Ltd. is a professional enterprise engaged in high-strength polypropylene industrial silk, engineering fiber, high-strength polypropylene filament, woven geotextile and polypropylene glow-in-night silk and other products. It is located in Yunting industrial zone of Jiangyin City near Taihu Lake in the south and Yangtze River in the north, and the traffic is very convenient.
High-strength polypropylene filament with environmental protection, non-toxic, acid-proof, alkali resistance, heat shrinkage of small, light-weight, low thermal conductivity, the static electricity savings, and the advantages of little hygroscopic, less product has great potential in industrial yarn, can be widely used in industrial sling, seat belts, conveyor belt, woven geotextile, filter cloth, canvas, wire, cable, cable and other industries, etc., It is a novel textile material to replace nylon and polyester.
