The main goal of this work was to increase disperse dye substantivity for cotton cellulose containing fabrics via modification with monochlorotriazine-beta-CD (MCT-beta-CD), which posses hydrophobic cavities along with remarkable capability to form inclusion complexes with organic substances through host-guest interactions. The proper conditions for simultaneous alkaline-disperse dyeing as well as grafting of MCT-beta-CD onto and/or within cotton and cotton/PET (50/50) blend fabrics were presented. As a result of this novel approach, the obtained dyeings showed a remarkable improvement in their depth of shades along with a significant enhancement in their UV-protection properties. The extent of improvement in disperse dyeing and in subsequent UV-protecting is determined by the nature of substrate, extent of modification, type and concentration of PEG and disperse dye as well as the union-bath conditions, i.e. temperature, time and pH. Mode of interactions, SEM Of untreated and grafted C/PET fabric, as well as fastness properties of the obtained dyeings were also investigated. (C) 2009 Elsevier Ltd. All rights reserved
