Among the various industrial yarns of synthetic fibers, the high strength and impact resistance of polypropylene high-strength fibre, 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.
Polypropylene high-strength fibre characteristics: because of its high strength, light weight, small uniform heat shrinkage, flame retardant, anti-aging, low thermal conductivity, wear resistance, seawater corrosion resistance, etc., polypropylene high-strength yarn has small color difference, good color fastness, Advantages of high strength. Therefore, polypropylene high-strength yarns are widely used in safety nets, safety belts, safety ropes, industrial slings, industrial cloths, cables, container bags, anti-cracking engineering fibers, high-pressure fire hoses, conveyor belts, industrial sewing threads, polypropylene anti-corrosion In fields such as split fiber, it is a new ideal chemical fiber material to replace polyester, nylon, polyethylene and nylon.
Properties of polypropylene high-strength fibre:
1. The strength ofpolypropylene high-strength fibre 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 fields.
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.
