In this study, the dyeing of silk fabric with Polygonum cuspidatum extracts was investigated. The contents of this study are as follows. First, the proper dyeing conditions were investigated by measuring the dye uptake (K/S value) that depended on the dyeing conditions when silk fabric was dyed with Polygonum cuspidatum extract. Second, the brightness (L), hue, and chroma differences that appear after mordanting with Al, Cu and Fe were investigated by measuring the CIELAB and Munsell values. And third, the colorfastness and antibacterial property were measured. When the silk fabric was dyed with Polygonum cuspidatum extract, the proper dyeing conditions were a colorant concentration of 90% v/v, a dyeing of time 100 minutes, a dyeing temperature of 70℃, and a dyeing of pH 3. In mordanting methods, the dyeabilities of post-mordanting were higher than those of premordanting. The hue value displayed yellow (Y) and yellow-red (YR) in cases of pre and post mordanting. The C value decreased by the mordanting of Polygonum cuspidatum extracts. Generally the colorfastness of mordanted fabrics was improved by mordanting. The dyed fabrics showed a 90.6% of Staphylococcus aureus reduction rate, and the dyed and mordanted fabrics showed 97.1% bacteria reduction rate. The dyed and mordanted fabrics showed above 90.5% Klebsiella pneumoniae reduction rate, and Cu mordant revealed the most effective bacterial reduction.
