Embodiment 1

[0027] The following components are formulated according to mass percentages as follows: nano silver 10Kg, adhesive-107 glue 11Kg, polyurethane 3Kg, softener-organic silicon 3Kg, microcapsule solution 20Kg, dispersant-ZD 3Kg, water 40Kg , a total of 100Kg.

[0028] At 35°C, put 10Kg of nano-silver into 3Kg of polyurethane and 40Kg of water, stir at a speed of 1500 rpm for 1 minute, add the microcapsule solution and stir until it becomes an emulsion, then add 3Kg of ZD in turn Finally, stir for 1-3 minutes, add 11Kg of 107 glue, stir for 5 minutes, then add 3Kg of organic silicon and stir for 3 minutes to make a nano-silver microcapsule finishing agent for use;

[0029] The pure cotton yarn of JC18tex was dipped and rolled twice in the microcapsule finishing agent, and the yarn was taken out, wherein the liquid-carrying rate of the yarn was 100%. The yarn padded in the microcapsule finishing agent is pre-baked at 80°C for 3 minutes and then qualitatively baked at 140°C for 3 m...

Embodiment 2

[0032] The following components are dosed according to mass percentage as follows: nano silver 15Kg, adhesive-107 glue 15Kg, polyurethane 3Kg, softener-organic silicon 4Kg, microcapsule solution 20Kg, dispersant-ZD3Kg, water 30Kg, A total of 100Kg.

[0033] At 40°C, put 15Kg of nano-silver into 3Kg of polyurethane and 30Kg of water, stir for 2 minutes at a speed of 1700 rpm, add the microcapsule solution and stir until it becomes an emulsion, then add ZD in turn After 3Kg, stir for 1-3 minutes, add 15Kg of 107 glue, stir for 5 minutes, then add 4Kg of organic silicon and stir for 3 minutes to prepare a nano-silver microcapsule finishing agent for use;

[0034]The regenerated cellulose fiber yarn of 20tex is sprayed with microcapsule finishing agent, and the yarn is taken out, wherein the coverage rate of the yarn is 100%. The yarn sprayed with microcapsule finishing agent was pre-baked at 100°C for 5 minutes and then qualitatively baked at 160°C for 5 minutes to obtain regene...

Abstract

The invention relates to a preparation method of nano-grade silver antibiotic fabric. The method comprises the steps that: (1) under a temperature of 35-45 DEG C, nano-grade silver micro-particles are added to polyurethane and water; the mixture is stirred; a microcapsule solution is added to the mixture; the mixture is stirred, and an emulsion is obtained; stirring is continued; a dispersant, an adhesive and a softening agent are sequentially added, such that a nano-grade silver microcapsule finishing agent is obtained; (2) yarn is processed by using the nano-grade silver microcapsule finishing agent; pre-baking and shaping baking are carried out, and yarn with the nano-grade silver microcapsule is obtained; (3) the yarn with the nano-grade silver microcapsule is adopted as middle-layer weft yarn, and three-layered fabric is obtained by weaving. A pre-shaping locking treatment is carried out, such that the nano-grade silver antibiotic fabric is obtained. The preparation method provided by the invention is simple; the nano-grade silver microcapsule finishing agent is applied on the yarn, and comfortableness of the fabric is not influenced. According to the invention, the yarn with the nano-grade silver microcapsule is positioned in the middle layer of the three-layered fabric, and does not contact human body or external environment directly. Therefore, the fabric is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the field of preparation of functional fabrics, in particular to a preparation method of nano-silver antibacterial fabrics. Background technique [0002] In recent years, with the improvement of people's living standards and pace of life, people have higher and higher requirements for the comfort, health, safety and environmental protection of textiles. Textile finishing has become one of the important ways to improve the function of textiles and increase the added value of products. Using nano-microcapsule technology to make textiles functional is one of the hotspots in the future. The application of microcapsule technology in textiles is mainly in finishing. Various fabric finishing agents can be made into microcapsules and used for fabric finishing, such as hair removal, anti-virus, anti-fog, anti-fouling, anti-wrinkle, anti-fogging Shrinkage, deodorization, heat storage and heat preservation, softness, fragrance, flame re...
