Abstract

The invention discloses an anti-static and wear-resistant non-woven fabric. A preparation method comprises the following steps of firstly, preparing a metal organic framework taking zirconium as a center from zirconium tetrachloride and 2-aminoterephthalic acid, and then polymerizing silver nanowires on active sites of the metal organic framework in situ to obtain a filler; adding the filler into a melt of polyethylene glycol terephthalate and polytrimethylene terephthalate, and carrying out melt extrusion to obtain fiber filaments; enabling the fiber filaments to be subjected to surface roughening treatment through tetrahydrofuran; and immersing the fiber filaments with rough surfaces in coating liquid under a low-temperature condition, reacting for a period of time, taking out the fiber filaments, putting the fiber filaments into polypropylene resin dispersion liquid, reacting, taking out the fiber filaments, and airing the fiber filaments to obtain the non-woven fabric. Through the synergistic effect of all the components, the prepared non-woven fabric is relatively good in elasticity; when scratches appear on the surface of the non-woven fabric, self-repairing can be conducted through movement of molecular chains in a non-woven fabric coating; and the non-woven fabric is good in anti-static performance, high in friction resistance, not prone to pilling, firm, durable and relatively high in practical value.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an antistatic and wear-resistant non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are not interwoven and knitted together by yarns one by one, but chemical fibers, fabric fibers and other fiber materials are directly bonded together by physical methods; the process of non-woven fabrics The process is short, the production speed is fast, the output is high, the cost is low, and the use is wide. It is used in medical and health care, clothing, industry, agriculture and other fields. [0003] However, the non-woven fabrics produced by the prior art have poor wear resistance and mechanical properties, and the bonding force between fibers is weak, and non-woven fabrics are prone to snags, pilling, and fiber breakage during use; at the same time , Non-woven fabrics are prone to static electr...
