Problems solved by technology

Second, the finishing effect should be durable, resistant to machine washing, dry cleaning and hot pressing, which is the biggest challenge for antibacterial finishing
[0009] Triazole fungicides are organic small-molecule antibacterial agents, which belong to dissolution-type antibacterial agents. Although they have excellent antibacterial properties, they have the disadvantage of being easily washed off when applied on fabrics, and have poor affinity for cellulose fibers. Less used in textiles

Embodiment 1

[0023] In a 500mL four-necked flask equipped with an electric stirrer and a thermometer, add 14.5g of triadiazole alcohol, a small amount of catalyst and 150mL of chloroform, stir to dissolve, cool to 0-5°C, and dropwise add 100mL of cyanuric chloride in chloroform ( It contains cyanuric chloride (11.5g), after the dropwise addition, react at 0-5°C for 12h, filter at room temperature, remove the catalyst, distill the reaction solution under reduced pressure to obtain a viscous liquid, recrystallize with distilled water to obtain a white The solid is the reactive triazole fungicide. The product yield is 62.3%.

[0024] Add an appropriate amount of antibacterial agent obtained in the first step, 5 g of nonylphenol polyoxyethylene ether, and 4.6 g of polyoxyethylene ether sorbitan ester into 100 g of deionized water to prepare an emulsified working solution. According to the liquor ratio of 1:15, the pure cotton white knitted fabric was impregnated. Put the fabric into the work...

Embodiment 2

[0034] In a 500mL four-necked flask equipped with an electric stirrer and a thermometer, add 14.5g of triadiazole alcohol, a small amount of catalyst and 150mL of chloroform, stir and heat to dissolve, raise the temperature to 40°C, and add dropwise 55g / L of 1-amino 3 , 180 mL of a chloroform solution of 5 dichloro-s-triazine, after the dropwise addition, react at 40°C for 12h, cool to room temperature and filter, remove the catalyst, distill the reaction solution under reduced pressure to obtain a viscous liquid, Recrystallize with distilled water to obtain a white solid, which is a reactive triazole fungicide. The product yield is 54.1%.

Abstract

The invention discloses a preparation method and application of a textile anti-bacterial finishing agent containing a triazole ring. A reaction type triazole anti-bacterial finishing agent is prepared by taking triazole derivatives as main anti-bacterial groups, tri-nitrogen benzene rings in the triazole derivatives as auxiliary anti-bacterial groups and active substituent groups of the triazole derivatives as potential reactive groups to complete reaction by a one-step method at 0-40 DEG C in the presence of a catalyst. 8-20% of anti-bacterial agent emulsion prepared from the anti-bacterial agent is used for anti-bacterial finishing of cotton fabrics. The cotton fabrics carry out thermal reaction for 40 minutes at 40-80 DEG C, then sodium carbonate is added, reaction is continued for 40 minutes, and then the fabrics are taken out, washed with water and dried in the air, thus completing the finishing processes. The cotton fabrics after undergoing anti-bacterial finishing have a good anti-bacterial effect on escherichia coli and staphylococcus aureus and have higher washability.

Description

technical field [0001] The invention belongs to the field of antibacterial finishing agents, in particular to a preparation and application method of an antibacterial finishing agent containing triazole derivatives. Background technique [0002] Microorganisms multiply rapidly due to human sweating, sebum and surface debris, especially when moist, nourished and at a suitable temperature. The reproduction of microorganisms will generate plaques on the fabrics, causing mildew, embrittlement and even deterioration of textiles. At the same time, microorganisms decompose various organic substances, produce unpleasant odors, and even discolor textiles, resulting in adverse effects on the human body during the application of textiles. influences. The purpose of antibacterial finishing of textiles is to endow textiles with good antibacterial function, protect textiles from being degraded by mold, prevent the spread of microorganisms, and reduce the cross-infection rate in public en...
