Abstract:

Nano-silver solution was prepared by deoxygenation with natural cactus solution, which is simple and non-polluting. The size and distribution of cactus silver nanoparticles were studied using HPPS and TEM. Functional treatment of the B. mori silk fabric was performed with nano-silver solution, and the antibacterial property and wash durability of the treated fabric were investigated. The results showed that the resultant cactus silver nanoparticles have a size about 50nm, the uniformity and the dispersivity is good. The experiments show that the finished fabric has good antibacterial activity. When the silver content on silk fabric was about 268.58 mg/kg, the bacterial ratio is over 99%, and the bacterial ratio is over 98% after washing 50 times, indicating the good antibacterial property and wash durability of the fabric.
