Abstract

Nylon 66 yarn was exposed to near-ultraviolet radiation in a dry oxygen atmosphere for exposure periods up to 240 hr. Dye take-up, viscosity, and density measurements, DSC thermograms, and wideline nmr spectroscopy were employed to assess the effects of the irradiation. Measureable changes were observed with each analytical technique. It was concluded that exposure of nylon 66 to the above conditions caused considerable chain scission in the defect regions, there was no detectable crosslinking, and the newly freed chain ends relaxed resulting in a more highly ordered fiber structure.
