ABSTRACT

In this study, we examined the influence of the pigment characteristic and dyeing condition on dyeing properties and functionality by using Perilla Frutescens L. Britt extracts, in which ethanol, distilled water and NaOH solution were used as 3 different solvents. Changes in dyeing conditions include variations in dye concentration, dyeing temperature, time and pH on dye uptake, and K/S values were compared according to these changes. Additionally, color changes were observed according to the use and types of mordant. Ultraviolet-visible spectrum was utilized to investigate the pigment characteristic, and as a result, chlorophyll was identified in ethanol extract, whereas tannin was identified both in distilled water extract and NaOH solution extract. By using FT-IR analysis, these tannins in distilled-water-extract and NaOH solution extract were verified to be hydrolyzable tannin. When dyeing silk, dye uptake increased as dye concentration, dyeing temperature and time increased, while it decreased as pH of the extract increased. Fabrics dyed without a mordant produced Y-series colors, and fabrics dyed with mordants showed various colors depending on the mordant types. Even though color fastness to washing and light was unsatisfactory, fastness to rubbing and perspiration showed relatively high grade. Moreover, deodorant ability of dyed fabric improved.
