Embodiment 1

[0028] (1) Dissolve carboxymethyl chitosan and silicotungstic acid in water to prepare an antibacterial treatment solution. The mass concentration of carboxymethyl chitosan contained in the soaking solution is 2%, and the amount of silicotungstic acid is carboxymethyl 0.25% of the mass of chitosan, and then soak the organic cotton fiber in the antibacterial treatment solution for 1.5h at a temperature of 40°C, take it out and heat and dry it at 80°C to obtain the antibacterial modified organic cotton fiber. The reaction process was monitored by IR, and the hydroxyl content in the system decreased, indicating that the hydroxyl group participated in the reaction.

[0029] (2) Dissolve β-cyclodextrin and potassium carbonate in hot water at 80°C, then add dodecyltrimethylammonium chloride, and then add dropwise chloromethyl pivalate dissolved in toluene, pivalic acid The molar ratio of chloromethyl ester, potassium carbonate, dodecyltrimethylammonium chloride is 1:1:3%, the mass r...

Embodiment 2

[0034] (1) Dissolve carboxymethyl chitosan and silicotungstic acid in water to prepare an antibacterial treatment solution. The mass concentration of carboxymethyl chitosan in the soaking solution is 2.5%, and the amount of silicotungstic acid is carboxymethyl 0.25% of the chitosan mass, and then the organic cotton fiber is immersed in the antibacterial treatment solution, soaked at a temperature of 50 ° C for 1 hour, and then heated and dried at 85 ° C after taking it out to obtain the antibacterial modified organic cotton fiber.

[0035] (2) Dissolve β-cyclodextrin and potassium carbonate in hot water at 80°C, then add dodecyltrimethylammonium chloride, and then add dropwise chloromethyl pivalate dissolved in toluene, pivalic acid The molar ratio of chloromethyl ester, potassium carbonate, and phase transfer catalyst is 1:1.05:5%, and the mass ratio of β-cyclodextrin and chloromethyl pivalate is 1:1.5, and it is heated to 80°C under stirring for reaction. After the chloromet...

Embodiment 3

[0040](1) Dissolve carboxymethyl chitosan and silicotungstic acid in water to prepare an antibacterial treatment solution. The mass concentration of carboxymethyl chitosan in the soaking solution is 2.5%, and the amount of silicotungstic acid is carboxymethyl 0.5% of the chitosan mass, and then soak the organic cotton fiber in the antibacterial treatment solution, soak for 1 hour at a temperature of 50°C, take it out and heat and dry it at 90°C to obtain the antibacterial modified organic cotton fiber.

[0041] (2) Dissolve β-cyclodextrin and potassium carbonate in hot water at 80°C, then add dodecyltrimethylammonium chloride, and then add dropwise chloromethyl pivalate dissolved in toluene, pivalic acid The molar ratio of chloromethyl ester, potassium carbonate, and phase transfer catalyst is 1:1:5%, and the mass ratio of β-cyclodextrin and chloromethyl pivalate is 1:2, and it is heated to 80°C under stirring for reaction. After the chloromethyl pivalate is added dropwise, co...

Abstract

The invention discloses a process for preparing an antibacterial and anti-mite swaddling clothes product from organic cotton, and relates to the technical field of organic cotton processing. Organic cotton fibers are used as raw materials; after antibacterial and anti-mite treatment, the organic cotton is endowed with excellent antibacterial and anti-mite performance, and meanwhile, the safety is high; the problem of potential safety hazards existing in conventional chemical antibacterial agents and anti-mite agents is solved; and the antibacterial and anti-mite swaddling clothes product is high in washing resistance, still has good antibacterial and anti-mite performance after being washed for multiple times and is long in antibacterial and anti-mite time effect.

Description

Technical field: [0001] The invention relates to the technical field of organic cotton processing, in particular to a process for preparing antibacterial and anti-mite swaddling products using organic cotton. Background technique: [0002] Organic cotton, the term is literally translated from English Organic Cotton, and it is also called ecological cotton or biological cotton in other foreign languages. In the production of organic cotton, natural farming management is mainly based on the biological control of diseases and insect pests with organic fertilizers. Chemical products are not allowed, and all natural pollution-free production from seeds to agricultural products. And with the "Safety and Quality Standards for Agricultural Products" promulgated by various countries or WTO / FAO as a measure, the content of toxic and harmful substances such as pesticides, heavy metal nitrates, harmful organisms (including microorganisms, parasite eggs, etc.) in cotton is controlled wit...
