Cotton Fabric Functionalization with Cyclodextrins

Cyclodextrins are cyclic oligosaccharides obtained by enzymatic degradation of starch.they have been used in recent years to functionalize textile substrates. in this paper, a reactive cyclodextrin derivative, monochlorotriazinyl-β-cyclodextrin, was covalently bonded to cellulose in cotton fabric. the grafted amount was determined by gravimetric method and the treated fabrics were analyzed by fourier transform infrared spectroscopy (ftir) and thermogravimetric analysis (tga). inclusion compounds with phenolphthalein and the cyclodextrins grafted to the cotton fabric were made in order to verify that the cavities were available for inclusion compounds. triclosan was used to test the inclusion and the release capabilities of the obtained material. antibacterial tests of the cotton fabric treated with cyclodextrins and triclosan were performed and the treated fabrics showed excellent performance.
