Abstract

This application discloses an antibacterial and impermeable fabric, which uses modified ultra-high molecular weight polyethylene fibers. The preparation method of modified ultra-high molecular weight polyethylene fibers is as follows: (1) pre-swelling: ultra-high molecular weight polyethylene fiber raw materials, n-butyl Alcohol, lauryl ethoxy sulfobetaine, nano-silver antibacterial agent and glycerol triacetate are mixed, stirred, heated and kept warm to obtain a pre-swelling liquid; (2) Modified liquid preparation: fumed silica, single-walled Carbon nanotubes, maleic anhydride, n-butanol, dodecyl ethoxy sulfobetaine, nano silver antibacterial agent and glycerol triacetate are mixed and stirred to obtain a modified solution; (3) jelly spinning: Mix the modified liquid and the pre-swelling liquid, stir, heat up and keep warm; twin-screw extrusion, extrude, cool and solidify; mix the gelatin filament and ethanol solution, extract the solvent, and dry; stretch the gelatin filament with high heat to obtain Modified ultra-high molecular weight polyethylene fiber, process temperature and quantity control, has the effect of antibacterial, anti-seepage and increasing wettability.

Description

technical field [0001] The invention relates to an antibacterial anti-penetration fabric. Background technique [0002] Ultra-high molecular weight polyethylene fiber (UHMWPE), also known as high-strength and high-modulus polyethylene fiber, refers to a high-performance fiber made of polyethylene with a relative molecular weight of more than 1 million through spinning-extraction-drying-super-stretching. In the prior art, the preparation of ultra-high molecular weight polyethylene fibers usually uses gel spinning technology, which was first invented by DSM company in the Netherlands. In the jelly spinning technology, polyethylene with a relative molecular weight of more than 1 million is usually used as a raw material, and the suspension obtained by mixing the raw material with a suitable solvent is used as a spinning stock solution, and then the spinning stock solution is extruded through a screw It is sheared, homogenized and unwrapped by the machine, and then extruded thr...
