Abstract

This study was carried out to investigate dyeing characteristics of CDP(cation dyeable polyester)/silk knitted fabrics with disperse type cation dyes/acid dyes by one bath dyeing method in comparison with two bath dyeing method in the interests for rationalization of the dyeing process. The apparent color depth(K/S) of the disperse type cation dyes with CDP and that of acid dyes with silk decreased slowly with increasing pH values of dyebath with the exception of sharp decrease at alkali region for CDP. The contamination behavior of CDP by the acid dyes and that of silk by the disperse type cation dyes decreased with progressing of dyeing. The migration ratio(%) of the disperse type cation dyes with CDP is low compared with that of acid dyes with silk. The sediment in mixed dying solution of disperse type cation dyes and acid dyes remarkably less compared with that of regular type cation dyes and acid dyes at $100^{\circ}C$ regardless applying of preventer agent of precipitation. When CDP/silk knitted fabrics was dyed with by with mixtures of disperse type cation dyes/acid dyes one bath or two bath dyeing method, the characteristic of reflectance spectra of CDP components were greatly influenced by disperse type cation dyes and that of silk components by acid dyes. It was confirmed that K/S values of each components of CDP/silk knitted fabrics dyed by one bath dyeing method decreased slightly compared with two bath dyeing method.
