This study demonstrates the possibility of improving the transfer printability and fastness properties, as well as the ultraviolet-protecting functionality, of polyester, polyester ⁄ wool, polyester ⁄ cotton and polyester ⁄ viscose woven fabrics via pretreatment with monochlorotriazinyl b-cyclodextrin (MCT-b-CD), chitosan or ethylenediamine, followed by subsequent transfer printing with sublimable disperse dyes. The modification variables as well as the transfer printing conditions were optimised. The experimental results reveal that generating hydrophobic cavities (via grafting of b-CD) at the fabric surface, fixing of chitosan, with its amino groups, onto the finish ⁄ fabric matrix, or introducing amine functional groups, via aminolysis of the polyester component, results in obtaining transfer printed fabric samples with darker depth of shades and better fastness properties, as well as with higher ultraviolet-protecting functions. It was further noted that, in all cases, the enhancement in the imparted properties is governed by type of substrate, kind and extent of chemical modification, affinity for the sublimable disperse dyes, accessibility of generated hosting and fixing sites, as well as the ultraviolet-blocking capacities of the modified ⁄ post-printed substrates against damaging ultraviolet rays. The mode of interaction, as well as the surface morphology of some non-treated and treated fabric samples, was also investigated. Experimental MaterialsExperiments were carried out on woven polyester (220 g ⁄ m 2 ), polyester ⁄ wool blend (70 ⁄ 30-230 g ⁄ m 2 ), polyester ⁄ cotton blend (70 ⁄ 30-370 g ⁄ m 2 ) and polyester ⁄ viscose blend (70 ⁄ 30-380 g ⁄ m 2 ) fabrics.Cavasol W7MCT {MCT-b-CD [1; average molecular weight ca. 1560, degree of substitution 0.3-0.6 per anhydroglucose unit (Wacker, Germany)], chitosan [2; degree of deacetylortion of 82.9%, average molecular weight ca. 140 500 dalton (Vanson Inc., USA)], Arkofix NDW [modified dimethylol-dihydrroxyethylene urea, DMDHEM, 3 (Clariant, Egypt)], Disperse Red FB 60, Disperse Blue 2BL 56 and Disperse Orange 25 (Sinochem Ningbo, China)} were of commercial grade.EDA (4), polyethylene glycol (PEG-600, 5), citric acid, acetic acid, magnesium chloride hexahydrate (MgCl 2 . 6H 2 O), and toluene were of laboratory grade.Pretreatment with MCT-b-CD Fabric samples were impregnated by the aqueous solution containing MCT-b-CD (0-60 g ⁄ l), DMDHEU (20 g ⁄ l), MgCl 2 AE6H 2 O ⁄ citric acid mixed catalyst (5 g ⁄ l) and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
