18—THE TEMPERATURE-DEPENDENCE OF THE ELASTIC RECOVERY IN COURTELLE ACRYLIC FIBRES

Abstract

The effect of temperature on the stress–strain diagram and elastic recovery has been investigated for single fibres of Courtelle acrylic fibre. Most of the measurements were made in the wet state at temperatures of up to 80°C. Results show the presence of a glass-transition region at about 6O°C, and this has been confirmed by differential thermal analysis.
