The uniqueness of high-strength polypropylene yarn is...


Among the industrial yarns of various synthetic fibers, the high strength and impact resistance of high-strength polypropylene yarns and their flexibility and chemical resistance make them a highly competitive variety. In addition, its production equipment investment is low, raw material prices are cheap, energy consumption is less, environmental pollution is less, and it has obvious technical and economic advantages.


high-strength polypropylene yarn performance:


1. high-strength polypropylene yarn is as strong as polyester and nylon industrial yarn, and it is exactly the same under wet and dry conditions.


2. Polypropylene has a density of 0.919/cm', which is the lowest density of 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 high-strength polypropylene yarn as raw material will cost much less than polyester or nylon industrial yarn. In addition, because polypropylene absorbs less moisture (MO.1%), it is especially suitable for marine products and other products that require non-hygroscopicity.


3. Good wear resistance and flexibility


4. Tolerant to mildew, polypropylene is not affected by insects and bacteria.


5. Good stability to chemicals. Due to the absence of reactive groups in the molecular structure of polypropylene, the stability to acids, bases and other chemicals is very good, even better than polyester and nylon, making it suitable for many chemical applications.


6. UV resistance and dyeability have been solved. Polypropylene itself has poor light resistance, but excellent UV radiation degradation resistance can be achieved by using polypropylene chips with stabilizers, and the product is suitable for outdoor use. Polypropylene dyeing is difficult, but it has been solved by adding a dyeing aid or coloring the stock solution.
