Abstract

Summary: The characterization of textured yarn is of great significance for both producers and final users. The influence of the texturing parameters (draw ratio and heater temperature) on the characteristics of the textured polyamide yarn has been investigated in this study. Textured yarn was characterized by the degree of orientation, degree of crystallinity, breaking characteristics, shrinkage, elasticity characteristics, the contents of the end groups and degree of whiteness. It was observed that the mentioned characteristics changed as a function of time. The influence of yarn ageing on its characteristics was assessed. The parameters of polyamide textured yarn structure were determined by DSC.
