Grafting of Cotton Fiber by Water-Soluble Cyclodextrin-Based Polymer

beta-cyclodextrin (CD)-based linear water-soluble polymners were synthesized in a controlled manner by a One-pot synthesis method. The synthesized water-soluble Polymer was covalently fixed Onto Cotton surfaces by a polycondensation reaction at controlled conditions. Grafting on cotton fibers transfers the cyclodextrin properties onto its surface. The grafting occurred through the formation of a crosslink between hydroxyl groups of cotton and CID polymer. This was confimed using FTIR spectroscopy, DSC, tensile strength, computer color matching, and solvent fastness analysis. The tensile strength of modified fiber samples was unchanged as compared to that of unmodified fiber samples. The percentage of grafting depended Oil a number of parameters and specifically on (i) temperature, (ii) time, and (iii) pH of the reaction medium. Similarly, under optimum conditions the weight increase on cotton fabric due to the grafting reaction could reach 10-15 wt %, The grafted fabric shows good dyeability and solvent fastness properties.
