Abstract

The effect of high-energy irradiation on cotton-cellulose was studied in inert atmosphere and in the presence of oxygen. A decrease in the degree of polymerization from 1200 to 330 was measured after irradiation with a dose of 15 kGy (dose rate 100 Gy/h) and further gradual decrease was measured when the dose was increased up to 100 kGy. At lower doses a slight increase in crease recovery angle was found as compared to the unirradiated sample. In the FTIR spectra of the same sample the appearance of the absorbance of carbonyl groups (band at 17301750 cm-1) was found as a consequence of the oxidative degradation. Cracks on the surface of the fibers were observed by scanning electron microscope on samples irradiated with doses higher than 100 kGy.
