Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to provide an anti-wrinkle, anti-bacterial and non-irritating shirt for the problems that the shirt has poor wrinkle resistance, easy to wrinkle, easy to shrink, and needs to be ironed after washing, and the antibacterial finishing agent has poor safety and is easy to cause skin diseases. The preparation method of shirt fabric finishing agent, the present invention first reacts chitosan solution and linoleic acid and linolenic acid to obtain fatty acid chitosan, then extracts coconut oil from coconut meat, adds aloe juice, Citronella essential oil, dextrin, benzethonium chloride, etc. are mixed to obtain a mixed solution, and the mixed solution is heated and mixed with malic acid, sodium hypophosphite, triethanolamine, butane tetracarboxylic acid and ethylene glycol to obtain a finishing agent. The finishing agent prepared by the invention has good anti-wrinkle effect on fabrics, high wrinkle resilience, small strength loss, good antibacterial property, long antibacterial time, no stimulation to human body, safety and environmental protection

example 1

[0018] Weigh 10g of chitosan, mix it with 10% acetic acid solution at a solid-to-liquid ratio of 1:15, transfer the mixed solution into a three-necked flask, put it in a water bath, raise the temperature to 70°C, and stir under this condition until the chitosan The sugar is completely dissolved. After dissolving, add 1.2g carbodiimide, 5g linoleic acid and 20g methanol solution of 15% linolenic acid in sequence to the flask. After the addition is completed, keep stirring and react for 5 hours. After the reaction is completed, cool down to room temperature. Suction filter the reactants in the solution to obtain the filtrate, put it into a dialysis bag, dialyze with 60% ethanol solution and deionized water for 20 hours, freeze-dry after dialysis to obtain fatty acid modified chitosan, and set aside; select mature Coconut, cut it open with a knife, scrape off the coconut meat in the coconut shell after pouring out the coconut juice, put the coconut meat in an oven and dry it compl...

[0024] Weigh 20g of chitosan, mix it with 15% acetic acid solution at a solid-to-liquid ratio of 1:15, transfer the mixed solution into a three-necked flask, put it in a water bath, raise the temperature to 90°C, and stir under this condition until the chitosan The sugar is completely dissolved. After dissolving, add 2.5g carbodiimide, 10g linoleic acid and 30g methanol solution of 15% linolenic acid to the flask in turn. After the addition is completed, keep stirring and react for 8 hours. After the reaction is completed, cool down to room temperature. Suction filter the reactants in the solution to obtain the filtrate, put it into a dialysis bag, dialyze with 60% ethanol solution and deionized water for 28 hours, freeze-dry after dialysis to obtain fatty acid modified chitosan, and set aside; select mature Coconut, cut it with a knife, pour out the coconut juice and scrape off the coconut meat in the coconut shell, put the coconut meat in an oven and dry it completely, then c...

Abstract

The invention discloses a preparation method of an anti-wrinkle antibacterial irritation-free shirt fabric finishing agent and belongs to the field of fabric finishing agents. According to the preparation method, chitosan liquid reacts with linoleic acid and linolenic acid to obtain aliphatic chitosan; coconut oil is extracted out of copra; the aliphatic chitosan and the coconut oil are mixed; then aloe juice, cymbopogon essence oil, dextrin and benzethonium chloride are added into the aliphatic chitosan and the coconut oil to be mixed to obtain mixed liquid; the mixed liquid is mixed with malic acid, sodium hypophosphite, triethanol amine, butane tetracarboxylic acid and ethylene glycol in a heated mode to obtain the finishing agent. The prepared finishing agent is better in anti-wrinkle effect to fabric, high in wrinkle rebound resilience, small in strength loss, good in antibacterial performance, lasting in antibacterial time, free of irritation to a human body, safe and environment-friendly; the antibacterial property can reach 92% or more, the antibacterial property can reach 80% or more after fabric is washed for 100 times repeatedly, and a wrinkle recovery angle is 200 degrees or more.

Description

technical field [0001] The invention discloses a preparation method of an anti-wrinkle, antibacterial and non-irritating shirt fabric finishing agent, which belongs to the field of fabric finishing agents. Background technique [0002] As we all know, clothing fabrics have a large number of fiber gaps and micropores because of the cross-overlapping of fibers (Wu Huiying 2006), which provides a good microenvironment for the growth of microorganisms, and at the same time, the fiber gaps also absorb a large amount of human surface secretions, becoming ideal for microorganisms. The source of nutrition, the growth of microorganisms on the fabric will not only lead to moldy spots, peculiar smell, and fiber strength reduction in the fabric, but the growth of pathogenic bacteria will also cause itching, allergic reactions or other skin diseases in the human body, thus affecting people's life. Cause inconvenience, even endanger people's health. It is particularly important to endow ...
