TempératureIndex. décimale : 677.4 Textiles artificiels Résumé : The post-spinning operation has a predominant effect on the tenacity and elongation of drawn filaments. Rate of drawing at a constant temperature has an opposite effect. As the rate of drawing is low, the polymer has enough time to relax from the drawing stresses and shows low deformation behavior. As the rate of drawing is increased, the material is able to draw through the formation of a neck. At very high rates, the material may not be able to relax at ail and the build-up of elastic stresses leads to a brittle failure. The settings were done as per the standard and then optimized to check the performance of polyester filament for tenacity and elongation by changing the draw force. It had been noted that tenacity increases with an increase in D/F with reduced elongation from 2.1 to 2.93 gpd with gradually decreased elongation.
