example 1

[0027] Add 0.208g of ethyl glycolate, 0.494g of propyltriethoxysilane isocyanate, and 0.0034ml of dibutyltin dilaurate into a glass bottle, and stir in a water bath at 40°C for 6h. Add the product into a three-neck flask containing nano-zinc oxide ethanol aqueous solution, in which ethanol 135mL, water 65mL, zinc oxide 2g, and stir at 60°C for 12h. The product is filtered and washed with ethanol, dried and ground to obtain modified nano-zinc oxide powder.

example 2

[0029] Weigh 0.1g of modified nano-zinc oxide powder and place it in 100mL of distilled water for ultrasonic dispersion for 1h, pour the obtained nano-zinc oxide aqueous dispersion into the dyeing cup of the high-temperature and high-pressure dyeing machine, add 2g of polyester fabric at the same time, and heat the fabric under high temperature. For high-pressure dipping, heat up to 75°C at a rate of 2°C / min; then raise the temperature to 125-135°C at a rate of 1°C / min and keep warm for 30 minutes at 3 atmospheres; finally, lower the temperature of the dyeing cup to room temperature . Take out the loaded fabric, wash it in cold water, and dry it to get the final antibacterial PET fabric, its structure and diffusion effect are as follows figure 1 and 2 shown.

Abstract

The invention relates to improvement of an antibacterial treatment method of a textile fabric, in particular to a manufacturing method of an antibacterial PET (polyethylene terephthalate) fabric containing modified nano-zinc oxide, which comprises the following steps: step 1, mixing ethyl glycolate, isocyanate propyl triethoxy silane and dibutyltin dilaurate according to a ratio to prepare a mixture 1; step 2, mixing nano-zinc oxide, ethanol and water according to an installation proportion to prepare a mixture 2; step 3, mixing the mixture 1 and the mixture 2 in proportion, drying and grinding to obtain modified nano zinc oxide powder; 4, the modified nano zinc oxide powder is placed in distilled water to be subjected to ultrasonic dispersion for 1 h, the dispersion liquid is poured into a dyeing cup of a high-temperature and high-pressure dyeing machine, meanwhile, the polyester fabric is added, and high-temperature and high-pressure dip dyeing is conducted on the fabric; nano-zinc oxide is modified to improve the dispersity of the nano-zinc oxide on the polyester fabric, and special groups are introduced, so that the compatibility of a blended polymer is improved, and the washing fastness and antibacterial effect of the fabric are improved.

Description

technical field [0001] The invention relates to the improvement of an antibacterial treatment method for textiles, in particular to a method for manufacturing an antibacterial PET fabric containing modified nanometer zinc oxide. Background technique [0002] With the improvement of living standards, people pay more and more attention to the quality of life, hoping to obtain comfortable and safe clothing, as well as a hygienic and healthy living environment. People's requirements for clothing are not only cold and warm, but also fashionable and beautiful; functional, safe and healthy textiles have gradually been favored by people. With the needs of people's daily life and work, the consumption of PET fabric is gradually increasing. However, when the environment is humid and the temperature and humidity are suitable, it can provide a large amount of nutrients for microorganisms to make them multiply. In addition, the sweat stains, grease, and dander constantly produced by th...
