the infrared spectra and dielectric properties of cotton fibers pretreated for one day with toluene, methanol, and mixtures of the two have been investigated after drying the samples for 1 and 4 days the effect of $gamma$ -radiation on the crystallinity and dielectric properties of the solvent-treated was examined. the samples were irradiated in air and also in the presesnce of the solvents. the data obtained indicate that the addition of toluene to methanol increases the rate of uptake of methanol by cotton. moreover, it is found that irradiation of cotton fibers in the presence of toluene assists the oxidation of the cotton while irradiation in the presence of methanol reduces the oxidation effects of $gamma$ -radiation.
