Abstract
In this paper, we investigate the effect of texturing parameters in a false-twist draw-texturing process on the mechanical properties and the structure of polyamide yarns. A high-temperature heater was used in the study. The important effects of texturing temperature and time on the mechanical, crimp and structural parameters were studied. Detectable changes in overall crystalline orientation, crystal size and perfection of the crystals as a result of changing the texturing temperature and heater residence time were evaluated. Filament breakage rate was also investigated as a function of the D/Y ratio. An analysis of variance was carried out in order to determine the significance of the results.
