The influence of the texturing speed and the degree of stretching on breaking characteristics of the textured PES yarn

Abstract

Mechanical properties of textured PES yarns depend on their structural characteristics and texturing process parameters. In this work, the results of breaking characteristics of textured PES yarns formed with various technological production parameters are presented. The samples of textured PES yarns were produced on a modern machine with a short heating zone. The textured yarn was formed at the first heater temperatures of 350 °C, 400 °C and 450 °C with the constant temperature of the second heater of 180 °C and with D/Y ratio of 2.20. The texturing speed was changed in the range of 500 m/min up to 1100 m/min with stretching degrees of 1.665, 1.675 and 1.685. The results obtained can be used for the selection of optimal production parameters of PES yarn at various texturing speeds. Also, the relationships which can be applied in industry for predicting breaking characteristics depending on texturing process parameters are presented.
