The effects of large doses of UV radiation, relating to actual operational use during 1, 2 or 5 summer seasons, on changes of chemical structures, crystalline structures, morphology and tensile properties of four types of polyamide 6 were investigated. The fibers differed in cross-section shape and mat degree caused by TiO2 addition. The fibers were tested using, among others, SEM and IR methods. Critical dissolution time (CDT) was also investigated.
