Processing technology for prolonging antibacterial and mildew-proof performance of cotton and linen blended fabric

Abstract

The invention discloses a processing technology for prolonging antibacterial and mildew-proof performance of a cotton and linen blended fabric, and relates to the technical field of blended fabric processing. The processing technology specifically comprises the following steps of 1, pretreating cotton fibers; 2, preparing manganese dioxide nanowires; 3, uniformly mixing the manganese dioxide nanowires and the pretreated cotton fibers, drying, adding nano-silver into molten paraffin to obtain a paraffin mixed solution, and adding a mixture into the paraffin mixed solution for vacuum impregnation; 4, blending the antibacterial cotton fibers, linen fibers and polyester fibers, and processing to obtain the finished cotton and linen blended fabric. According to the processing technology, the mixture of the pretreated cotton fibers and the manganese dioxide nanowires is used as a carrier, the nano-silver particles are added into the molten liquid paraffin, vacuum and impregnation treatment is carried out, so that the nano-silver and the paraffin permeate into gaps of the pretreated cotton fibers together, leakage and loss of the nano-silver are limited, and therefore, the antibacterial property of the blended fabric can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of blended fabric processing, and in particular relates to a processing technology for prolonging the antibacterial and mildewproof properties of cotton and linen blended fabrics. Background technique [0002] There are a large number of microorganisms and fungi in nature, which brings great troubles to people's lives, especially in summer, food is easy to rot and deteriorate due to improper storage, and wet clothes are prone to mold, color and odor, so antibacterial functional textiles have always been people's pursuit . 4,000 years ago, the ancient Egyptians impregnated the mummy shroud with refined herbal medicine, and it is still not moldy or rotted after vicissitudes of life. It can be called the origin of antibacterial textiles. At present, antibacterial has become the basic performance requirement for fabrics in the brand, especially for sports and leisure fabrics, there are many new fibers and proce...

Problems solved by technology

The second method is that the metal is only distributed on the surface of fibers and fabrics, and it is not resistant to washing, rubbing, oxidation, friction, and unstable conductivity, but the treatment process is relatively simple, and the cost is easy to control according to the specific requirements of customers. , is a method widely used in the market

For example, Chinese patent CN2019103509124 discloses a method for preparing anti-mildew and antibacterial fabrics. It adopts the first method. By improving the traditional antibacterial agent, the nano-silver powder is dispersed into nano-silver ions by adding a dispersant and ultrasonic treatment. , and add auxiliary antibacterial ingredients. After polymerization, the antibacterial agent is loaded with deacetylated chitin as a carrier to make it have good loadability. At the same time, the fabric matrix is ​​pretreated, and the fabric matrix is ​​oxidized under acidification conditions to make the fabric matrix The surface is full of oxygen-containing active groups. The polymeric antibacterial agent can unite with the oxygen-containing active groups on the surface of the fabric matrix through the intermolecular force and diffuse into the fabric matrix, so that it will not greatly reduce the antibacterial property due to excessive rinsing times. This process is mainly to diffuse the polymerized antibacterial agent into the interior of the fabric matrix and attach it to the surface of the fabric matrix through intermolecular forces, so that the antibacterial properties of the fabric will not be greatly reduced after repeated rinsing. However, in practical applications, the influence of external factors The impact will easily lead to the weakening of the intermolecular force, resulting in the reduction of the adhesion of the polymeric antibacterial agent on the surface of the fabric matrix, resulting in the easy diffusion of the polymeric antibacterial agent from the interior of the fabric matrix, resulting in the loss of the polymeric antibacterial agent and the reduction of the antibacterial performance of the fabric
