Problems solved by technology

[0004] But above-mentioned method is all not suitable for the antibacterial treatment of real silk fiber or goods, and its reason is: 1, real silk fabric generally all will be processed through dyeing or printing, carries out grafting treatment on real silk fiber, can form polyallylic acid on the surface of real silk fiber Copolymers and homopolymers of dimethylhydantoin; it will greatly affect the change of fabric surface dyeing color; 2. In the chlorine-containing solution of real silk fibers, chlorine will greatly damage the fiber strength, and it is easy to Yellowing of silk fibers

Embodiment 1

[0037] Dissolve 12.1 grams of allyl bromide in 20 grams of methanol solution, called component A; dissolve 12.8 grams of 5,5-dimethylhydantoin and 5.6 grams of potassium hydroxide in 50 grams of water, called component B ; Slowly add component A dropwise to component B while stirring, keep the temperature of the reaction system at 60°C, react for 2 hours and then cool down. At room temperature, the product was vacuum-dried to obtain 3-allyl-5,5-dimethylhydantoin.

[0038] Add 17.2 grams of 3-allyl-5,5-dimethylhydantoin, 53.0 grams of acrylonitrile, and 0.2 grams of ammonium persulfate into 100 grams of acidic water-soluble solution in a certain order, and keep the temperature of the reaction system at 70 ° C , reacted for 1 hour and then cooled. An allyldimethylhydantoin-acrylonitrile copolymer was obtained.

[0039] 50 grams of allyl dimethyl hydantoin-acrylonitrile copolymers are heated in alkaline solution to obtain allyl dimethyl hydantoin-acrylonitrile copolymers, A mixt...

Embodiment 2

[0042] The preparation method of 3-allyl-5,5-dimethylhydantoin is the same as that in Example 1.

[0043] Add 12.1 grams of 3-allyl-5,5-dimethylhydantoin, 44.5 grams of acrylonitrile, and 0.12 grams of ammonium persulfate into 100 grams of acidic water-soluble solution in a certain order, and keep the temperature of the reaction system at 75°C , reacted for 1 hour and then cooled. An allyldimethylhydantoin-acrylonitrile copolymer was obtained.

[0044] The hydrolysis and chlorination method of the cyano group in the allyl dimethyl hydantoin-acrylonitrile copolymer is the same as that in Example 1.

[0045] Prepare a solution of 25% allyl dimethyl hydantoin-acrylonitrile copolymer, 5% sodium chloride, and 1% softener, pad and pad real silk products, with a liquid rolling rate of 80%, and bake at 100°C to 110°C Dry to make antibacterial silk products.

Embodiment 3

[0047] The preparation method of 3-allyl-5,5-dimethylhydantoin is the same as that in Example 1.

[0048] Add 6.9 grams of 3-allyl-5,5-dimethylhydantoin, 29.7 grams of acrylonitrile and 0.11 grams of ammonium persulfate into 100 grams of acidic water-soluble , reacted for 1 hour and then cooled. An allyldimethylhydantoin-acrylonitrile copolymer was obtained.

[0049] The hydrolysis and chlorination method of the cyano group in the allyl dimethyl hydantoin-acrylonitrile copolymer is the same as that in Example 1.

[0050] Prepare a solution of 30% allyl dimethyl hydantoin-acrylonitrile copolymer and 2% softener, pad and pad real silk products with a liquid rolling rate of 80%, and dry at 100°C to 110°C to obtain antibacterial silk products.

[0051] The antibacterial silk products prepared by the above-mentioned three kinds of embodiments adopt the ASTM E2149-01 shaking flask test method to calculate the bacteriostatic rate, and the test conditions are: sample 1.0g, 50ml 0.3...

Abstract

The present invention discloses an antibacterial agent applied to silk fiber. The antibacterial agent comprise a copolymer represented by the general formula (I), wherein E1 represents hydrogen or chlorine; R2 represents cyano, carboxylic acid or sodium carboxylic; R3 represents cyano, carboxylic acid or sodium carboxylic; m and n refer to degrees of polymerization and m plus n is equal to 8-16. The present invention also discloses the application of the antibacterial agent to preparation of antibacterial silk fiber or products and also an antibacterial silk fabric processed with the antibacterial agent. The silk fabric processed with the antibacterial agent of the present invention has good fastness to washing as well as long antibacterial effect and is resistant to luster change or yellowing.

Description

technical field [0001] The present invention relates to antibacterial agent for real silk fiber, its application and antibacterial real silk fabric. More particularly, the present invention relates to be used for real silk fiber, provide the antibacterial agent that has good washing fastness for real silk product but do not cause surface color and luster change and yellowing, realize real silk fabric lasting antibacterial effect, and it has antibacterial property in preparation The application in the real silk fiber or product, and the antibacterial silk fabric obtained by using this kind of antibacterial agent. Background technique [0002] Recently, reports on the use of antimicrobial agents to improve the antibacterial effect of textile fabrics are very active. There are many kinds of antimicrobial agents used in textile fabrics, which have been reported in the literature [Zhu Yawei, Ren Xuehong, Hu Yun, Current Situation of Antibacterial Finishing of Textiles, Printing ...
