Problems solved by technology

However, there is a space barrier between the fiber macromolecules of the silk fabric itself, which makes it difficult for the antibacterial finishing agent to attach to the surface of the silk fabric, thus affecting the antibacterial finishing effect of the silk fabric.

Embodiment 1

[0017] A kind of finishing process of antibacterial breathable real silk fabric, described process comprises the following steps:

[0018] (1) Mix the silk fabric with the sodium periodate aqueous solution, and react in the dark for 2 hours at room temperature. After the reaction, add ethylene glycol to neutralize the residual sodium periodate, wash it repeatedly with deionized water, and dry it naturally ;

[0019] (2) Submerge the silk fabric treated in step (1) in dimethyl sulfoxide, drop ethylenediamine into it, and react at room temperature for 8 hours. After the reaction, add sodium cyanoborohydride to the reaction system , the reaction was continued for 12 hours at room temperature, and the product was washed with dimethyl sulfoxide after the end;

[0020] (3) Add the silk fabric treated in step (2) into the protoporphyrin solution dissolved in dimethyl sulfoxide, react in the dark for 12 hours at room temperature, take out the product and wash it with dimethyl sulfoxi...

Embodiment 2

[0027] A kind of finishing process of antibacterial breathable real silk fabric, described process comprises the following steps:

[0028] (1) Mix the silk fabric with sodium periodate aqueous solution, and react in the dark for 4 hours at room temperature. After the reaction, add ethylene glycol to neutralize the residual sodium periodate, wash with deionized water repeatedly, and dry naturally ;

[0029] (2) Submerge the silk fabric treated in step (1) in dimethyl sulfoxide, drop ethylenediamine into it, and react at room temperature for 12 hours. After the reaction, add sodium cyanoborohydride to the reaction system , continue to react at room temperature for 24 hours, and wash the product with dimethyl sulfoxide after the end;

[0030] (3) Add the silk fabric treated in step (2) into the protoporphyrin solution dissolved in dimethyl sulfoxide, react in the dark for 24 hours at room temperature, take out the product and wash it with dimethyl sulfoxide and deionized water s...

Embodiment 3

[0037] A kind of finishing process of antibacterial breathable real silk fabric, described process comprises the following steps:

[0038] (1) Mix the silk fabric with the sodium periodate aqueous solution, and react in the dark for 6 hours at room temperature. After the reaction, add ethylene glycol to neutralize the residual sodium periodate, wash it repeatedly with deionized water, and dry it naturally ;

[0039] (2) Submerge the silk fabric treated in step (1) in dimethyl sulfoxide, drop ethylenediamine into it, and react at room temperature for 24 hours. After the reaction, add sodium cyanoborohydride to the reaction system , the reaction was continued for 48 hours at room temperature, and the product was washed with dimethyl sulfoxide after the end;

[0040] (3) Add the silk fabric treated in step (2) into the protoporphyrin solution dissolved in dimethyl sulfoxide, react in the dark for 36 hours at room temperature, take out the product and wash it with dimethyl sulfox...

Abstract

The invention discloses an antibacterial air-permeable fabric and a finishing process thereof. The process comprises the steps of firstly processing the surface of a real silk fabric, and carrying outgrafting reaction on protoporphyrin. Compared with the prior art, the finishing process has the advantages that (1) the real silk fabric is obtained through the finishing process, the internal spaceresistance of a real silk fiber is overcome, and the grafting of protoporphyrin on the surface of the fabric is promoted, so that the real silk fabric has good antibacterial capacity; (2) the graftingin the process is firm, so that the stable and permanent antibacterial capacity of the real silk fabric is guaranteed, and the antibacterial capacity can be maintained after the real silk fabric is washed for several times; and (3) the real silk fabric finished by virtue of the process can still preserve soft hand feel and good air permeability.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a functional silk fabric, in particular to an antibacterial breathable silk fabric and a finishing process thereof. Background technique [0002] The antibacterial finishing of textiles began in the 1940s and has been widely used, covering various fabrics. The post-finishing treatment of fabrics with antibacterial finishing agents is an effective means to make fabrics have antibacterial ability. [0003] At present, the widely used antibacterial finishing agents are mainly organic antibacterial agents. This kind of antibacterial finishing agents can inhibit bacteria in a broad spectrum and will not cause bacteria to develop drug resistance. They are efficient and safe, and are widely used in various textiles. However, such antibacterial finishing agents have problems such as poor durability and control of dissolution, which need to be solved. In recent years, inorganic antibac...
