Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2021 / V.33,no.3,Sept Title The Dyeing Properties and Antibacterial Function of Perilla frutescens var. acuta Extract on Cotton Authors Seongsuk Kim and Youngmi Park Institution/Affiliations Yeungnam University Pages/Total page pp.105 ~ 112 / 8 Language Korean Abstract This study investigated the proper dyeing conditions, fastness and functionality of cotton fabrics dyed with Perilla frutescens var. acuta extract. Repeat dyeing, combination dyeing of persimmon juice and fermentation dyeing were conducted as dyeing conditions. It was confirmed that the ΔE and the K/S value of cotton fabrics dyed with Perilla frutescens var. acuta extracts depending on repeat dyeing and combination dyeing slightly increased. Furthermore, the fastness to washing of persimmon combination dyeing and fermentation dyeing was very good. The fastness to rubbing was shown to be above grade 4 in all methods, and the fastness to light was not as good as grade 3 or lower. The persimmon juice dyeing, Perilla frutescens var. acuta extract repeat dyeing 4 times and combination fermentation dyeing showed very good antimicrobial abilities. Thereafter, additional studies are needed to improve the fastness to light and alternatives to further improve the dyeing properties.
