Description

Technical Field

[0001] The invention relates to the technical field of textile materials, in particular to an antistatic polypropylene filament and a processing method thereof. Background Art

[0002] Polypropylene is the Chinese trade name for synthetic fiber isotactic polypropylene fiber made from propylene, a byproduct of petroleum refining, also known as polypropylene fiber. The raw material source is abundant, the production process is simple, and the product price is relatively low compared to other synthetic fibers. The physical and mechanical properties of the fiber are: high strength, wet strength and dry strength are basically the same, small specific gravity (0.91), wear resistance and corrosion resistance, etc.

[0003] Polypropylene fiber has filaments (including undeformed filaments and expanded deformed filaments), staple fibers, bristle fibers, split fibers, hollow fibers, shaped fibers, various composite fibers and non-woven fabrics. It is mainly used to make carpets (including carpet base and suede), decorative fabrics, furniture fabrics, various ropes, strips, fishing nets, oil-absorbing felts, building reinforcement materials, packaging materials and industrial fabrics such as filter cloth and bag cloth. In addition, it is also increasingly widely used in clothing. It can be blended with a variety of fibers to make different types of blended fabrics. After knitting, it can be made into shirts, outerwear, sportswear, socks, etc. The quilt made of polypropylene hollow fiber is light, warm and elastic.

[0004] Since polypropylene itself has no polar groups and does not absorb water, fibers that do not contain water are electrical insulators. Natural fibers have good hygroscopicity, so static electricity is not serious. However, polypropylene has poor adsorption and is prone to static electricity during processing and use. Current antistatic fibers are mainly doped with antistatic agents, and the antistatic agents used are mostly various surfactants. However, this type of fiber has poor washing resistance and durability, and its antistatic properties disappear after processing.
