Oxidative susceptibility of partially carboxymethylated cotton to gamma radiation

Authors


Abstract

Partially carboxymethylated cotton with a DS of about 0.05–0.15 retains its original fibrous nature and exhibits a number of potentially valuable properties, such as a crisp hand with a slightly starched feel, increased moisture regain, water absorbancy, water permeability, changed dyeing characteristics, increased resistance to soiling from aqueous dispersions, and greater ease of soil removal.5–8 Furthermore, detailed studies have been reported on the behavior of partially carboxymethylated cotton toward oxidation and hydrolysis,9 vinyl graft polymerization,10 transfer printing,11,12 cross-linking,13 and thermal treatments.14
