Abstract

The invention discloses a preparation method of a long-acting anti-microbial textile. The preparation method concretely comprises the following processes: firstly a desizing or refining process is carried out for the textile, and pretreatment is carried out for the textile by using low temperature plasma; textile which is pretreated is dipped at a room temperature for 10-30 minutes in a mixed finishing solution which comprises a chitosan solution and a silver nitrate solution, the textile is taken out and superfluous finishing solution is rolled out, liquor retention is 100-150%, the textile which is dipped in the finishing solution is transferred into a piece of microwave equipment for carrying out treatment for a certain period of time, after the reaction ends, the textile is taken out and washed with water, and after drying, the anti-microbial textile is obtained. The anti-microbial textile has the advantages of excellent anti-microbial properties, washing resistance, lasting anti-microbial effects, simple preparation technology, and low chemical pollution; the method overcomes the problems of complex processes, bad stability of nanometer silver, bad anti-microbial durability and the like existed in the prior art.

Description

technical field [0001] The invention relates to a preparation method of antibacterial textiles, in particular to a preparation method of long-acting antibacterial textiles, belonging to the technical field of textile functional finishing. Background technique [0002] In daily life, people will inevitably come into contact with various microorganisms, which pose a threat to human health. With the improvement of chemical technology and people's quality of life, various antibacterial materials emerge in an endless stream. The emergence of nanotechnology has brought about a qualitative leap in the bactericidal ability of precious metal silver particles at the nanometer size. Nano silver has broad-spectrum antibacterial properties and is not easy to produce drug resistance. It has the advantages of high efficiency, safety and high stability. Silver-based antibacterial agents are widely used in medical and health, textile, food, environment and other fields. Chitosan is a natur...
