β‐cyclodextrin(CD) was incorporated in cotton fabric following pad‐dry‐cure technique employing maleic anhydride as modifying agent under the dual influence of free radical polymerization catalyst ammonium peroxodisulfate [(NH 4 ) 2 S 2 O 8 ] and esterification catalyst tetrasodium pyrophosphate (Na 4 P 2 O 7 ). β‐cyclodextrin(CD) can be esterified if treated with maleic anhydride (an unsaturated dicarboxylic acid) due to the presence of hydroxyl groups in β‐cyclodextrins and also such compound can form inclusion complex with essential oils. The retention of essential oil and its sustained release after repeated post wash treatments was determined quantitatively by UV–vis spectrophotometry.
