The main purposes are to make women's underwear, carpets, decorative fabrics, furniture fabrics, various ropes, strips, fishing nets, oil absorbing felts, building reinforcement materials, packaging materials and industrial fabrics, such as filter cloth, bag cloth and so on.

The biggest advantage of polypropylene is that it is light in weight and is the lightest of the common chemical fibers. Therefore, the same weight of polypropylene can produce a higher coverage than other fibers. Strong extensibility, light weight and good warmth, low hygroscopicity, almost no moisture absorption, the general moisture regain rate under atmospheric conditions is close to zero.

However, it has a wicking action that transfers water vapor through the capillary in the fabric, but does not itself absorb any absorption. Borneo show that the dyeability of polypropylene is poor, the chromatogram is not complete, but the method of coloring the original liquid can be used to make up for the deficiency, and it has good chemical resistance. In addition to concentrated nitric acid, concentrated caustic soda, polypropylene to acid and alkali It has good resistance and is suitable for use as filter materials and packaging materials in addition to underwear. Light resistance is poor, thermal stability is also poor, easy to age, not resistant to ironing. However, it is possible to improve the anti-aging property by adding an anti-aging agent at the time of spinning.
