Abstract	Three chemically modified cotton fabrics, viz, hydrocellulose, peroxide nxycellulose and hypochlorite oxycellulose having comparable DPn values in the range 1800-600 "He prepared and their chemical and physical characteristics were studied. From the assessment of chemical properties, it is found that (i) hvdroccllulose possesses high contents of aldehyde groups, predominantly of the reducing type, with low carboxy I and moderately high carbonyl groups, (ii) peroxide oxyccllulose possesses moderate contents of reducing aldehyde groups and moderately high caboxyl and carbonyl groups, (iii) hypochlorite oxycellulose possesses very high contents of carboxyl groups along with the high non-reducing type of aldehyde groups and slightly low contents of carbonyl groups. The resilience properties of these chemically modified cotton fahrics are comparable and are also not affected by decrease in DPn value. Evaluation of strength-abrasion properties at different DPn levels shows that cotton fabric modified with sodium hypochlorite gives best performance at all DPn values, while the other two are comparable, The rate of fall in the strength-abrasion properties with decreasing DPn values is minimum for peroxide oxvcellulose followed by hypochlorite oxycellulose and maximum for hydro cellulose.
