EFFECT OF γ-RAY IRRADIATION ON THE PROPERTIES OF POLYVINYL CHLORIDE FIBERS

The effect of gamma radiation on the physical properties of P. V. C. fibers were investigated. The following results were obtained;1) Tenacity, specific gravity, and viscosity of the irradiated samples were decreased with irradiation2) Extinction coefficient of P. V. C. solutions was increased.3) Preciously heat decomposed fibers which had polyene structure showed resistance against the radiolysis.4) By heating the irradiated fibers the property against the thermal schrinkage had shown improvement even by the small dosage. This fact might be explained by the end-linking due to the radiation-induced radicals.
