Abstract
Fabric crease-recovery measurements are reported for temperatures from 30 to 90°C and covering a time range for recovery from 15 sec to 30 min.
Measurements were made on identical twill fabrics made up from Acrilan. nylon 6.6, Terylene, a polyester co-polymer, Vycron, and wool fibres, using a modified A.K.U. crease-angle-recovery tester. A new method for analysing the time-dependence of the recovery as a sum of exponential terms is described and the results are displayed as graphs of initial and final recovery angle as a function of temperature.
Measurements were also made of the dynamic tensile properties of the constituent fibres over a temperature range; the second-order transition temperatures are tabulated.
