초록
Recently there has been a growing interest in the use of natural dyes in textile applications. Natural dyes canexhibit better biodegradability and generally have a higher compatibility with the environment. In this study, the colorantsclove and their dyeabilities on the fabrics were studied. Aditionally the fastness to washing and light, and the effects onantimicrobial properties were also investigated. Cotton fabrics were treated with a crosslinking agent epichlorohydrin inthe presence of chitosan to provide the cotton fabrics the dyeing properties of natural dye(clove) by the chemical linkingof chitosan to the cellulose structure. This process was applied by means of the conventional mercerizing process. Thechitosan finishing and durable press finishing of the cotton fabrics occurred simultaneously in the mercerization bath. Thedyeability(K/S), which was obtained by CCM observation, remarkablely became increased when the crosslinked chitosanconcentration was higher. The hue value indicated reddish yellow with increasing the crosslinked chitosan concentration.And the color fastness to washing and light was the almost the same. The chitosan treated cotton fabrics showed veryhigh activities with almost 100% reduction.
