Embodiment 1

[0036] Example 1, chitosan 1%, honeysuckle extract 0.8%, citric acid 2%, tartaric acid 1.5%, sodium hypophosphite 2%. Preparation method: ①Add a certain amount of water in advance into the reaction kettle with agitator, put the required chitosan into the water, stir and disperse, and heat to 50-70℃; ②In 1-2 hours, slowly dissolve the chitosan Add citric acid and tartaric acid into the kettle to react with chitosan to dissolve the chitosan. After the dissolution, continue to stir and keep warm for 2 hours; ③ Add the honeysuckle extract into the kettle and stir to dissolve; ④ Add sodium hypophosphite and stir; ⑤ Make up the required water to make the chitosan concentration 1%.

Embodiment 2

[0037] Example 2, N, N, N-trimethylammonium chloride chitosan 1.5%, citric acid 4%, wild chrysanthemum extract 0.8%, rhubarb extract 0.3%, sodium hypophosphite 2.5%. Preparation method: ① Put N, N, N-trimethylammonium chloride chitosan into a reaction kettle with a stirrer, then add the required amount of water to stir and heat to 30-70°C to dissolve it; ② Slowly add citric acid into the kettle, after adding, continue to keep warm and stir for 2 hours; ③Add sodium hypophosphite and stir; ④Add plant extracts in turn and stir to dissolve.

Embodiment 3

[0038] Embodiment three, 0.5% of hydroxypropyl chitosan, 0.6% of O-carboxymethyl-N, N, N-trimethylammonium chloride chitosan, 2.5% of butane tetracarboxylic acid, 1% of citric acid; Wild chrysanthemum flower extract 0.5%, dandelion extract 0.4%, tea leaf extract 0.6%, mugwort leaf extract 0.6%, clove extract 1%, aloe extract 0.8%, sodium hypophosphite 2%. Preparation method: ① Put hydroxypropyl chitosan and N, N, N-trimethylammonium chloride chitosan in turn into a reaction kettle with a stirrer, then add the required amount of water to stir and heat to 40 Dissolve it at -80°C; ② slowly add butane tetracarboxylic acid and citric acid into the kettle, and continue to heat and stir for 2 hours; ③ add sodium hypophosphite and stir; ④ at 20-60°C, add in sequence The plant extract is stirred and dissolved.

Abstract

The invention discloses a method for performing antibacterial and antivirus treatment on textiles by utilizing natural biomaterials. The method is characterized by comprising the following steps of treatment liquid preparation, impregnation of preprocessed cotton in the treatment liquid, press-rolling, preliminary drying, baking, washing with water, drying, and inspection of finished products. The prepared treatment liquid is prepared from chitosan loaded to cellulose fibers, a plant extract loaded to cellulose fibers, an organic acid cross-linking agent and sodium hypophosphite in the mass ratio of the chitosan to the plant extract to the organic acid cross-linking agent to the sodium hypophosphite being (0.1-2% ) to (0.1-3% ) to (1-10% ) to (1-8% ). According to the method disclosed by the invention, heavy metal antibacterial agents such as nano-silver and chemical synthesis antibacterial agents, generating potential damage to human bodies, are not used, and the natural biological extract is used as an antibacterial antivirus material, has favorable compatibility to the human bodies, is safe and comfortable to use, and is free from toxic or side effects.

Description

technical field [0001] The invention relates to the technical field of antibacterial and antiviral finishing of textiles, in particular to a method for using natural biological materials to carry out antibacterial and antiviral finishing of textiles. Background technique [0002] Microorganisms such as bacteria and viruses are ubiquitous in the living environment of human beings, causing great harm to human beings, especially to infants, the elderly and those with low immune function. For example, in 1995, the number of deaths caused by bacterial infection in the world reached 17 million. In 1996, the Escherichia coli infection incident occurred nationwide in Japan, the mad cow disease and foot-and-mouth disease in the United Kingdom, and the SARS in my country in 2003 and the subsequent bird flu. Bacteria and viruses are related and have caused huge losses to human life and property. For this reason, countries all over the world have spent a lot of time and energy to develo...
