Abstract

The invention relates to a method for preparing anti-microbial blended fabric. The method comprises the steps that blended fabric formed by interweaving of warps containing 50% of cotton, 30% of linen and 20% of bamboo fiber and wefts containing 100% of cotton is grafted into MCT-beta-CD, then the MCT-beta-CD grafted blended fabric is placed in a 0.01-10 g / L silver nitrate solution to be dipped for 60 min, dipping and padding are both conducted twice, the blended fabric is placed in a 600 W microwave oven to be heated for 8 min, and then the anti-microbial blended fabric is obtained. According to the method for preparing the anti-microbial blended fabric, the cotton / linen / bamboo fiber blended fabric is taken as the base material, in-situ generation of the nano-silver anti-microbial blended fabric is achieved with the microwave radiation method through MCT-beta-CD grafting, and the obtained anti-microbial blended fabric has excellent anti-microbial performance and washing fastness.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for preparing an antibacterial blended fabric. Background technique [0002] Although natural cellulose has the advantages of wearing comfort, renewability and biodegradability, but in the process of taking, because the fiber has a large specific surface area and strong moisture absorption capacity, fiber products are very easy to attach microorganisms, and for Its reproduction and propagation create conditions that cause damage to fiber strength, stains and discoloration, unpleasant odors, and even the spread of diseases, affecting human health. Therefore, in the research on the modification of cellulose, an important research direction is to realize the antibacterial properties of cellulose and reduce the damage of bacteria to the human body. Nano-silver is often used as an antibacterial finishing agent due to its safe, non-toxic and efficient antibacterial properties, and its...
