The characteristics of polypropylene high-strength yarn: polypropylene high-strength yarn has the characteristics of high strength, light weight, small uniform heat shrinkage, flame retardant, anti-aging, low thermal conductivity, abrasion resistance, and seawater corrosion resistance. It also has small color difference, good color fastness, Advantages of high strength.
Among the industrial yarns of various synthetic fibers, the high strength and impact resistance of polypropylene high-strength yarn, as well as its flexibility and chemical resistance make it a very competitive variety. In addition, its production equipment investment is low, raw material prices are cheap, energy consumption is minimal, environmental pollution is low, and it has obvious technical and economic advantages.
Properties of polypropylene high-strength yarn:
1. The strength of polypropylene high-strength yarn is comparable to that of polyester and nylon industrial yarns, and the strength is exactly the same in wet and dry conditions
2. Polypropylene has a density of 0.919/cm’, which is the smallest among all industrial synthetic fibers. Its density is only 66% of polyester (1.389/cma) and 80% of nylon (1.149/cm3). Considering the price and density of silk, the use of polypropylene high-strength silk as raw material will reduce the cost a lot compared to polyester or nylon industrial silk. In addition, because polypropylene fiber has low moisture absorption (MO.1%), it is especially suitable for marine products and other products that require non-hygroscopicity.
3. Good wear resistance and flexibility
4. Resistance to mildew. Polypropylene is not eroded by insects and bacteria.
5. Good stability to chemicals. Because polypropylene has no active groups in its molecular structure, it has very good stability to acids, alkalis and other chemicals, even better than polyester and nylon, making it suitable for many chemical industries.
6. Anti-ultraviolet and dyeing properties have been resolved. The light resistance of polypropylene itself is not good, but by using polypropylene chips with stabilizers, excellent resistance to ultraviolet radiation degradation can be achieved, and the product is suitable for outdoor use. It is difficult to dye polypropylene fiber, but it has been solved by adding dyeing aids or coloring the original liquid.
