Cotton shirt weight print cloth is carboxymethylated using a pad-roll technology. Chemical accessibility is characterized by iodine sorption capacity and water retention; The values obtained for the modified cotton are significantly higher than those of the untreated and mercerized control samples. Layered clothing systems are made from combinations of treated and control fabrics, and pesticide penetration and retention are studied suing radiolabeled methyl parathion. When the outer layer of the clothing sys- tem is carboxymethylated, 30 to 45/100 more pesticide is trapped by that layer than when the outer layer is the untreated or the mercerized control fabric.
