Abstract

The invention relates to a method for preparing silver-carrying antibacterial blended fabric by instant coffee. The method comprises the following steps: mixing 0.01-10 g / L instant coffee solution and 0.01-100 g / L silver nitrate solution according to the volume ratio of 10:1 to 1:10; stirring the mixture for 10 to 600 minutes at a uniform speed at the temperature of 30 to 80 DEG C to obtain a nano-silver colloid solution; washing the nano-silver colloid solution repeatedly by using ethyl alcohol and de-ionized water; centrifuging, and drying to obtain silver nano-particles; soaking cotton / linen / bamboo fiber blended fabric into the nano-silver solution with the concentration of 0.01-10 g / L; and soaking twice and rolling twice. According to the method for preparing the silver-carrying antibacterial blended fabric by the instant coffee, the commercially available instant coffee serves as a reducing agent and a stabilizing agent; and the method has the advantages of simplicity, mild reaction, greenness, environmental friendliness and the like. The prepared nano-silver is used in the field of textiles; the blended fabric with sterilization efficacy can be prepared; and the additional values of the textiles are greatly improved.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for preparing silver-loaded antibacterial blended fabrics from instant coffee. Background technique [0002] Textiles are recognized as a medium for the growth of microorganisms such as bacteria and fungi. Microbial communities in nature widely exist in the surrounding environment, and can multiply rapidly once encountering suitable humidity, nutrients and temperature. Microorganisms growing on textiles not only affect the performance of textiles themselves, but also affect the health of users. Therefore, how to suppress or kill the microorganisms attached to textiles, especially the textile industry, is an urgent problem to be solved. [0003] Antibacterial textiles can increase the added value of products and meet people's needs for health and environmental protection. Therefore, they have attracted more and more attention from textile researchers and have great market potent...
