Problems solved by technology

[0004] Adding nano-silver to thermal underwear to make antibacterial underwear has a long history, but they generally add nano-silver particles in the process of making synthetic fibers, or soak the cloth in a silver-containing solution, and then let the silver absorb Deposited on the surface of the cloth; the defect of the former is that the artificial synthetic fibers are not skin-friendly enough, and the warmth retention effect needs to be improved, while the defect of the latter is that the silver particles deposited on the surface of the cloth are not stable enough, and it is easy to fail after repeated washing

Abstract

The invention discloses long-acting antibacterial warm-keeping underwear and a preparation method thereof. The underwear is mainly prepared by blending foamed silver / graphene / cotton fiber compound and untreated cotton fibers, wherein the foamed silver / graphene / cotton fiber compound is prepared by the following steps: pretreating cotton fibers; then, soaking into a mixed solution of silver ammonia and graphene oxide; putting cotton fibers containing Ag<+> and graphene oxide into an ascorbic acid solution; and performing hydrothermal reduction, quickly freezing for molding, and lyophilizing in vacuum. The long-acting antibacterial warm-keeping underwear prepared by the method has the advantages of long antibacterial effect, good insulating effect, strong air permeability and good perspiration absorbability, can be easily washed, is able to bear rubbing, and is extremely convenient to arrange.

Description

technical field [0001] The invention belongs to the field of clothing, in particular to a long-acting antibacterial thermal underwear and a preparation method thereof. Background technique [0002] The material of thermal underwear is required to be light, soft, skin-friendly and breathable. Existing thermal underwear often adopts cotton fiber and artificial synthetic fiber to make, and the warming effect of cotton fiber is not ideal enough, and artificial synthetic fiber easily causes skin allergy, dry, rough, thickening, even chapped, dermatitis etc. occur. In addition, people wear more clothes in winter, and it is not easy to get rid of them in time after sweating, which causes bacteria to easily breed in the thermal underwear in the inner layer. [0003] The latest research has found that silver has an adsorption effect on microorganisms in the liquid. After the microorganisms are adsorbed by silver, the enzymes that play a role in respiration will lose their effectiven...
