ABSTRACT
Dyeability and antimicrobial property of dyed pig skin with Coptis chinensis Franch was investigated. Dyestuff was extracted with water and concentrated. Pig skin was dyed and mordanted according to various dyeing temperature, dyeing time, dyestuff concentration, mordanting methods and kinds of mordants. The results of this experiment were as follows: 1. Dyeability of pig skin with Coptis chinensis Franch was best at 200%(owf) dyestuff concentration, 50 dyeing temperature, and 20min. dyeing time. 2. Pre-mordanting by Cu improved the K/S values of dyed pig skin. 3. Surface color and color difference of dyed pig skin showed various results according to the mordants used : generally their color was yellow, Al post-mordanted pig skin showed the greatest color difference. 4. Color fastness to drycleaning was considerably high in case of staining compared to fading. Fastness to light was improved by Cu-mordanting while other treatments were not effective. 5. Antimicrobial property of samples was not different (99.9%) between untreated and treated.
