Monochlorotriazinyl beta-cyclodextrin (MCT beta-CD) was employed for the inclusion complexation with oils of cedarwood, clove, eucalyptus and peppermint to assess their release behavior from functionalized cotton. The process of MCT beta-CD grafting was optimized using response surface methodology with three independent factors including MCT beta-CD concentration, pH and curing temperature and effect of their second order interactions on dependent variables as % nitrogen content, % graft yield, tensile strength and wash durability was examined. The interaction of MCT beta-CD concentration and pH had the decisive effect on the investigated dependent variables. FTIR and % retained nitrogen confirmed the substantial retention of modified host on functionalized cotton after five vigorous wash cycles. 1HNMR characterized the full entrapment of oils within MCT beta-CD cavity on cotton. All the oils were substantially retained in the inclusion complexes with the MCT beta-CD before and after wash than when present uncomplexed on the treated cotton. Peppermint was the slowest to fade off and cedarwood was rapid in sublimation from the cyclodextrin moieties.
