The Application of Antibacterial Components of Euphorbia Humifusa Willd on Silk Fabrics

摘要

The minimal inhibitory concentration of the natural antibacterial components extracted from euphorbia humifusa willd (EHW) was investigated. The optimized fixation process and the antimicrobial activity of the treated silk fabrics were also studied. The results of the experiments indicated that the optimized fixation process parameters were extract concentration 60%, pH 4, 90°C and 60 minutes and the silk fabric had excellent antibacterial property. After 30 washing cycles the inhibitory rate of the silk fabric decreased from 100% to 61.8% and from, 89.31% to 67.86% against St. aureus and E. coli, respectively. A further treatment with rare earth improved the antibacterial durability of the silk fabric.
