絹과 PET 織物의 五倍子染色時chitosan 處理와 媒染이色相에 미치는 影響

Abstract

In natural dyeing, a number of supplementary methods have been practiced since deep shades of thedyed fabrics are not developed satisfactorily. The methods include using the mordants effectively orsubjecting the fabrics to reiterated dyeing processes. In this study, we obtained deep shades in the dyeingof fabrics using Rhusjara ica as the dyestuff and applied chitosan to the fabric specimens in order todiversify the colors.Silk fibers and PET(polyethylene terephthalate) fibers were pretreated using chitosan, and subsequentlydyed using different types of mordants.As the mordanting agents, Al, Sn, and Fe were employed. Various shades have been resulted in sincethe interactions of the mordants are different toward the silk fibers and PET fibers. In this study, weinvestigated the effect of the chitosan treatment along with the change of the mordanting agents on thecolor change for the silk and PET fibers.
