unmodified cotton fabric, cyanoethylated cottons having 0. 12, 0. 55, 0. 77, and 1. 24 n as well as cotton treated with naoh under conditions similar to those of cyanoethylation but in absence of acrylonitrile were exposed to gamma radiation doses (3. 199-31. 199 mrads). the six substrates before and after irradiation were assessed for copper number, carboxyl content, degree of polymerization, tensile strength, and elongation at break to determine the extent of degradation of these substrates. the effect of radiation dose on the nitrogen content of cyanoethylated cottons was also examined. it was found that degradation is higher the higher the radiation dose irrespective of the substrate used.
