초록
In this study, silk fabrics was dyed with sappan wood extracts fermented for 5 and 15 days, respectively, and then the dyeability, durability and the functionality of the dyed silk were investigated. Before dyeing, the silk was pretreated with chitosanacetic acid solution or chitosan acetic acid and illite blend solution. Thereafter, UV-Visible transmittance, color, fastness, antimicrobial activity, and the FIR emissivity were analyzed. As a result, the K/S value was higher in the samples that were not pre-treated or fermented. Regardless of fermentation, the lightfastness was not significantly different. The color fastness to washing was slightly better when the samples were pretreated with chitosan-acetic acid and illite, and then dyed with extracts fermented 5 days. In addition, all samples showed high antimicrobial activity of 99.9%, regardless of the fermentation. Far-infrared emissivity was confirmed to be slightly increased by the illite and chitosanacetic acid solution treatment compared to the untreated sample.
