DEGRADATION PROCESSES IN PRODUCTION OF VIDLON POLYCAPROAMIDE CORD THREAD

摘要

In spinning fibres on type PP-1000 IM machines,complex changes take place in polycaproamide,caused by the occurrence of thermal oxidation and thermal degradation processes.The content of carbonyl compounds increases with an increase in the temperature and draw ratio of the fibres in the polymer.Thermal degradation processes decrease with an increase in the drawing temperature.
