Establishment of Database of Color Matching System for Supercritical CO_2 Dyeing

摘要

Database of color matching system for supercritical CO_2 dyeing was established and its accuracy was verified. The K/S value curves of each of the trichromatic disperse dyes (C.I. Disperse Orange 30, C.I. Disperse Red 167 and C.I. Disperse Blue 79) were parallel, which indicated that the samples suits for building database of color matching system. The color matching system was emended with calibration coefficients that were derived from data of several samples dyed with a mixtures of disperse dyes in supercritical CO_2. The recipes for a given sample could be found with the calibrated color matching system in supercritical CO_2 dyeing.
