Embodiment 1

[0027] 1. The cotton fabric is subjected to plasma treatment. The conditions of plasma treatment are as follows: the gas uses oxygen, the treatment power is 200W, the pressure is 50Pa, and the treatment time is 25min;

[0028] 2. Mix 4g of kanamycin, 5g of UMP, 12.5g of Saccharomyces cerevisiae extract, 15g of sugar, and 8g of potassium dihydrogen phosphate, add it to 100mL of water, react at 30°C for 10 hours, and then filter to obtain an antibacterial finishing agent;

[0029] 3. Crush 64g of apple seeds, put them into 100mL of PBS buffer solution, stir well, extract at 4°C for 24h, filter, and freeze-dry the filtrate at -22°C to obtain a glycosidase preparation;

[0030] 4. Immerse 1g of the cotton fabric treated in step 1 in 18mL of antibacterial finishing agent, and put in 0.6g of glucosidase preparation, fully impregnate at 30°C for 72h, then wash and air-dry to obtain antibacterial cotton fabric.

Embodiment 2

[0032] 1. The cotton fabric is subjected to plasma treatment. The plasma treatment conditions are as follows: the gas uses oxygen, the treatment power is 100W, the pressure is 40Pa, and the treatment time is 15min;

[0033] 2. Mix 3g of kanamycin, 4g of UMP, 10g of Saccharomyces cerevisiae extract, 10g of sugar, and 5g of potassium dihydrogen phosphate, add it to 100mL of water, react at 28°C for 8 hours, and then filter to obtain an antibacterial finishing agent;

[0034] 3. Crush 50 g of apple seeds, put them into 100 mL of PBS buffer solution, stir well, extract at 2°C for 12 hours, then filter, and freeze-dry the filtrate at -42°C to obtain a glycosidase preparation;

[0035] 4. Immerse 1g of the cotton fabric treated in step 1 in 15mL of antibacterial finishing agent, and put in 0.5g of glucosidase preparation, fully impregnate at 20°C for 48h, then wash and air-dry to obtain antibacterial cotton fabric.

Embodiment 3

[0037] 1. The cotton fabric is subjected to plasma treatment. The conditions of plasma treatment are as follows: the gas uses oxygen, the treatment power is 300W, the pressure is 60Pa, and the treatment time is 30min;

[0038] 2. Mix 5g of kanamycin, 6g of UMP, 15g of Saccharomyces cerevisiae extract, 20g of sugar, and 10g of potassium dihydrogen phosphate, add it to 100mL of water, react at 37°C for 12 hours, and then filter to obtain an antibacterial finishing agent;

[0039] 3. Crush 80g of apple seeds, put them into 100mL of PBS buffer solution, stir well, extract at 8°C for 48h, then filter, and freeze-dry the filtrate at -17°C to obtain a glycosidase preparation;

[0040] 4. Take 1g of the cotton fabric treated in step 1 and immerse it in 20mL of antibacterial finishing agent, add 0.8g of glycosidase preparation, fully impregnate, the impregnation temperature is 37°C, and the impregnation time is 100h, then wash and air-dry to obtain antibacterial cotton fabric.

Abstract

The invention belongs to the technical field of textile fabric processing and discloses an antibacterial cotton fabric and a preparation method thereof. The preparation method specifically includes: (1) performing plasma treatment on cotton fabric; (2) mixing kanamycin, UMP, Saccharomyces cerevisiae extract, sugar, and potassium dihydrogen phosphate, adding them to water, and filtering after reaction to obtain an antibacterial finishing agent; (3) Apple seeds are pulverized, put into PBS buffer solution and fully stirred, filtered after leaching, and the filtrate is freeze-dried to obtain a glycosidase preparation; (4) The cotton fabric obtained through plasma treatment is immersed in an antibacterial finishing agent, And put into glucosidase preparation, fully impregnated; (5) wash and air-dry to make antibacterial cotton fabric. This antibacterial cotton fabric has long-lasting, broad-spectrum antimicrobial properties, is washable, and is non-toxic to humans and skin.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to an antibacterial cotton fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of health awareness, it is particularly important to develop textiles with excellent antibacterial properties. Cotton fabric is the textile material most in contact with the human body. It has good wearability, but it is porous and loose, easy to absorb various impurities, and is a carrier for reproduction and parasite pathogenic bacteria. Among the commonly used antibacterial finishing methods, silver ions and nano-silver are genetically and reproductively toxic to environmental organisms and the human body; conventional organic antibacterial agents are not washable, and free antibacterial agents have potential toxicity to the human body; natural antibacterial agents have insufficient antibacterial ...
