천연염료를 이용한 염색물의 항균, 소취성에 관한 연구(I) ―소 목―

A Study on the Antibacterial and Deodorization of Silk Fabrics Dyed with Natural Dye (II) ― Sappan Wood―

Antibacterial and deodorization properties of silk fabrics dyed with Sappan wood are investigated by Halo, Shake flask, Bioassay and Detection column methods.The results are obtained as follows; 1. Although K/S values increase with Al mordant and concentrate concentrations, these are decreased in 10% Al mordant concentration in case of 4mlg dye concentration. 2. Reduction ratios of bacteria increase with K/S values in various tests. 3. When undyed silk fabrics are treated with Al mordant, reduction ratios of bacteria are not varied with Al mordant concentrations. 4. Deodorization property of Al pre-mordanted dyeing silk fabrics is better than one of unmordanted dyeing and raw silk fabrics. 5. Antibacterial properties of Cu and Cr mordanted dyeing fabrics are better than ones of the dyeing fabrics treated with the other mordants. 6. Natural dyes extracted from Sappan wood show the good antibacterial and deodorization properties, and colorant among various components contained in Sappan wood has a excellent antibacterial and deodorization properties.
