Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2015 / V.27,no.1,Mar Title Combination Dyeing of Silk Fabrics with Extracts from Humulus japonicus and the Pruned Branches of Prunus persica Tree Authors Young Kab Ha and Jeong Sook Lee† Institution/Affiliations Gyeongsang National University Pages/Total page pp.80 ~ 95 / 16 Language Korean Abstract Abstract: In this study, the properties such as color, dye uptake and antibacterial function were examined through the application of combination dyeing and mixed dyeing with extracts from Humulus japonicus(hwansam) and the pruned branches of Prunus persica(peach) tree. In terms of dye uptake and surface color changes subject to the kind of mordants, methods and mixing ratio of dye, it was found that fabrics dyed by the pre-mordanting method with CuSO4 showed the red·green·yellow group colors, which were not seen in fabrics dyed with hwansam only. Color fastness was found strong at grade 4-5 with 96.3% of UV protection ratio. While the fastness to light was as fair as grade 3, it showed an excellent result of 99.9% bacteria reduction rate against Staphylococcus aureus with fair 58% deodorization rate and 21.2% antibacterial rate against Klebsiella pneumoniae. As stated above, the combination and mixed dyeing resulted in the meaningful outcomes with regard to color variations, dye uptake, color fastness and functional properties.
