Problems solved by technology

Polyamide fiber itself has very good wear resistance, but after research, it is found that there is still a lot of room for improvement in the wear resistance of polyamide, and the heat resistance of polyamide fiber is very poor, and it is easy to produce wear resistance in a dry environment. Therefore, it is necessary to design a wear-resistant synthetic fiber with stronger wear resistance, better heat resistance and better mechanical properties

Abstract

The invention discloses a synthetic fiber with strong wear resistance and a preparation method thereof. The synthetic fiber comprises pretreated polyamide fiber and a polyethylene-b-polydimethylsiloxane diblock copolymer. Mesoporous silica is coated in the synthetic fiber and is exposed after friction, so that the fiber is supported to a small extent, the friction force to the fiber is reduced, and the service life of the fiber is prolonged; pores of the mesoporous silica are filled with polyamide, so that reduction of the mechanical strength of the silica caused by the pores is made up, and the hardness and wear resistance of the mesoporous silica are improved; a silicon-oxygen structure with increased activity is introduced into a polyamide copolymer, so that the heat resistance and low-temperature strength of the polyamide copolymer are improved, the water resistance of the copolymer is improved, and the service life of the copolymer is prolonged; and polydimethylsiloxane and the polyamide fiber are copolymerized, so that the tensile strength of the fiber is improved, and the wear resistance of the synthetic fiber is further improved.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a synthetic fiber with strong abrasion resistance and a preparation method thereof. Background technique [0002] Synthetic fibers are made of synthetic polymers. Commonly used synthetic fibers include polyester, nylon, acrylic, polyvinyl chloride, vinylon, spandex, polyolefin elastic yarn, etc. This article mainly discusses nylon-polyamide fibers. Polyamide fiber itself has very good wear resistance, but after research, it is found that there is still a lot of room for improvement in the wear resistance of polyamide, and the heat resistance of polyamide fiber is very poor, and it is easy to produce wear resistance in a dry environment. Therefore, it is necessary to design a synthetic fiber with stronger wear resistance, better heat resistance and better mechanical properties. Contents of the invention [0003] The object of the present invention is to provide a synthetic fiber...
