Abstract

Modification of the fabric is one of the best routes to improve the affinity between dye and fabric. In this study, chemical modification of organic cotton fabric has been done by the greener way with the use of ß-cyclodextrin and chitosan and the modification level were measured by dyeing with natural dye (Nyctanthes arbor-tristis) parijataka. Results of dyeing showed better dye uptake after modification on organic cotton fabrics, especially in chitosan modification. SEM and FTIR studies reveals about the surface modification and the presence of ß-cyclodextrin and chitosan moiety on the modified fabric. CCM studies of modified and unmodified fabric reported that chroma (C*) values were found to be higher with modified fabric than unmodified fabric. Since the dyeability and other fastness properties of organic cotton are having better results. From an ecological point of view, organic cotton may be a better alternative to conventional cotton.
