Polypropylene staple fiber is mainly used to make carpets (including carpet bottom cloth and suet), decorative cloth, furniture cloth, all kinds of ropes, strips, fishing nets, linoleum, building reinforcement materials, packaging materials and industrial cloth, such as press cloth, bag cloth, etc. In addition, Polypropylene staple fiber is increasingly widely used in clothing. It can be blended with a variety of fibers to make different types of blended fabric. After knitting, it can be made into shirts, outerwear, sportswear, socks, etc. The floc quilt made of polypropylene hollow fiber is light, warm and elastic.

Polypropylene staple fiber moisture absorption and dyeing: light weight and good heat preservation; Almost no moisture absorption, but the core absorption ability is very strong, moisture absorption and sweat removal effect is obvious; Polypropylene hygroscopicity is very small, almost no hygroscopicity, the moisture return rate under general atmospheric conditions is close to zero. 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.

Polypropylene staple fibers do not contain chemical groups that can combine with dyes on the macromolecular structure, so dyeing is difficult. The melt coloring method is usually used to mix the pigment preparation and polypropylene polymer evenly in the screw extruder. After melting spinning, the colored fiber has high color fastness. Another method is copolymerization with acrylic acid, acrylonitrile, vinyl pyridine and other copolymerization or graft copolymerization, so that the introduction of polymer macromolecules can be combined with dye polar groups, and then directly dyed with conventional methods. In the process of polypropylene production, various additives are often added to improve the dyeing, light resistance and fire resistance.

Polypropylene staple fiber for civil use: can be spun or blended with wool, cotton or viscose fiber to make a variety of clothing materials. Can be used to weave all kinds of knitwear such as socks, gloves, knitwear, knitted pants, dish cloth, mosquito net cloth, quilt, warm packing, diapers, etc.

Industrial use of polypropylene staple fiber: carpet, fishing net, canvas, hose, concrete reinforced materials, industrial fabrics, nonwoven fabrics, etc. Such as carpet, industrial press cloth, rope, fishing net, building reinforcement material, oil absorbing blanket and decorative cloth. In addition, polypropylene film fiber can be used as packaging material
