A New Approach to the Study of Textile Dyeing Properties with Liquid Chromatography

Abstract

Frontal analysis gives retention volumes of basic dyes on acrylic fabric, rolled and inserted into a liquid chromatography column. The retention volumes indicate differences in adsorption and therefore in compatibilities of standard dye mixtures. A simple and useful relation, C_v = C_v ^o + mR - C_v ,0, results where m is a parameter fitted to the data, C_v 0 is the compatibility difference between C_v ^o and C_v when R = 0 (i.e., elution times are identical), and C_v ^o is the compatibility of one of the two dyes in the mixture. Hence, a new approach is proposed that not only allows determination of C_v using frontal analysis with an LC apparatus, but also defines compatibility in an objective manner as a continuous function.
