| Abstract: | It was found that during texturing, complex changes caused by degradation, primarily mechanical degradation, processes take place in the structure of PCA fibres. The most pronounced changes in the fibres are observed in texturing on FZ-27S machines, characterized by the highest degree of thermooxidative and mechanical degradation. The degradation processes that take place during texturing significantly affect the coloring of PCA fibres: fibres textured on FT-417 machines are colored at the highest rate.
