ABSTRACT
It was revealed that the photoconductivity spectra of various grades of cotton fibers doped with iodine are quite different. It was found that the electrical conductivity of cotton fibers undipped and doped with iodine and KMnO4 increases exponentially with increasing temperature. Infrared quenching and long-time relaxation of the photoconductivity of cotton fibers doped with iodine were detected. For the first time, it was found that with small doses of UV irradiation of silkworm green, the quality of silk fibers improves, and with large doses it worsens.
