한국 자생 꼭두서니 추출물에 의한 모시섬유의 염색성

Abstract

This study was carried out to investigate into the dyeability of ramie fabrics using theextract of native plant, red-dye madder (Rubia akane Nakai) in different conditions. Surfacecolor of ramie fabrics dyed with extracts from red-dye madder plants showed an order ofdescent YR. However, it was changed by the different mordants. Surface color of ramiefabrics treated with FeSO4, SnCl4, and tartaric acid was an order of descent Y, and thattreated with the ashes of common camellia, and bean straw was an order of descent R. Athigher temperatures, surface color and coloring matter concentration of ramie fabrics wereas follows that values of a increased, however, values of b decreased and values of L lowered.Coloring matter concentration increased in the order of 70℃, 90℃, and 60℃, and so on.Dyeing colors on the ramie fabrics showed an order of descent Y by pH 4 and 9 in dyestuffssolutions. Coloring matter concentration in terms of K/S values, more or less, was increasedat strong acids. Surface color by the concentration of dyestuffs solutions showed an order ofdescent YR irrelevant to the concentration of dyestuffs solutions. Coloring matterconcentration was increased at higher concentrations of dyestuffs solutions. Ten minuteswas sufficient for the dyeing of ramie fabrics in terms of surface color and coloring matter concentration.
