Embodiment 1

[0029] First, add ceramic powder into the reaction vat, then add 93% ethanol aqueous solution, add a pH regulator to adjust the pH value at 5-6, then add tetraethoxysilane and vinylmagnesium bromide, and add 100 ℃ water bath heating and magnetic stirring for 3 hours, after the reaction, the product was washed, dried and filtered to obtain the first product, and then the first product was stirred in the stirring tank for more than 2.5 hours, and then it was ground by rubber mill and entered into the cross-linking tank 7~ After 8 hours, modified ceramic powder was obtained; then, polyimide and chlorosilane were mixed in a ratio of 3:1, heated and stirred until the temperature reached 120°C, and an emulsifier was added to form the first component, and then added to Add sodium bicarbonate to the first component and mix evenly, and finally introduce the mixed solution into the silica sol, mix and cool to obtain a modified polyimide; then, take raw materials by weight, raw materials ...

Abstract

The invention discloses a nano-silver antibacterial fabric with good wear resistance and a preparation method thereof, the nano-silver antibacterial fabric with good wear resistance comprises at least one mixed fiber layer; and an antibacterial fiber layer which is bonded with the mixed fiber layer, wherein the surface of the antibacterial fiber layer is coated with a nano-silver antibacterial film; wherein the mixed fiber layer comprises the following components: carbon fibers, aramid fibers, polyethylene terephthalate, nano fluorocarbon, modified ceramic powder, modified polyimide and an auxiliary preparation, and the modified ceramic powder and the modified polyimide are added, so that the tensile strength, the wear resistance and the strength of the antibacterial fabric are greatly improved. The invention solves the problem that an existing nano-silver antibacterial material cannot meet the requirements of people in the aspects of tensile strength, abrasion resistance, hardness and the like is solved, and compared with single use of the modified ceramic powder and single use of the modified polyimide and simultaneous use of the modified ceramic powder and the modified polyimide, a better effect can be achieved, and synergistic interaction is achieved.

Description

technical field [0001] The invention relates to an antibacterial fabric, in particular to a nano-silver antibacterial fabric with good wear resistance and a preparation method thereof. Background technique [0002] Antibacterial fabric has good safety, it can effectively and completely remove bacteria, fungus and mildew on the fabric, keep the fabric clean, and prevent bacteria from regenerating and multiplying. [0003] Nano Silver (Nano Silver) is the metal silver whose particle size is nanoscale. Most of the nano-silver particle size is about 25 nanometers, which has a strong inhibitory and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, and will not produce drug resistance. Cotton socks made of nano-silver and combed cotton fibers have good antibacterial and deodorizing effects. [0004] However, the existing nano-silver antibacterial materials cannot meet people's needs in terms of tensi...
