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 abrasion resistance and a preparation method thereof, which comprises pretreated polyamide fiber and polyethylene-b-polydimethylsiloxane diblock copolymer. The mesoporous silica is coated in the inner friction of the synthetic fiber and leaks out, supporting the fiber itself in a small range, reducing the friction on the fiber and prolonging the service life of the fiber; the pores of the mesoporous silica are covered with polyamide It makes up for the reduction of the mechanical strength of silica caused by the pores, and improves the hardness and wear resistance of mesoporous silica; the silicon-oxygen structure with increased activity is introduced into the polyamide copolymer to improve the polyamide copolymer. Heat resistance and low-temperature strength increase the water resistance of the copolymer and increase the service life of the copolymer; the copolymerization of polydimethylsiloxane and polyamide fiber increases the tensile strength of the fiber itself, further increasing the resistance of the synthetic fiber Abrasive.

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...
