THE CONSTRUCTION AND FINISHING OF FABRICS BASED ON TERYLENE POLYESTER FIBRE IN RELATION TO CREASE-RECOVERY

Abstract
A study is made of some aspects of the relative crease-recovery of fabrics containing Terylene polyester fibre, wool, and blends of the two fibres. It is shown that wool is primarily affected in its crease-recovery by the presence of moisture, whilst Terylene fibre is subject to non-recoverable deformation imposed at high temperatures. The influence of structural and finishing variables on the crease-recovery of fabrics containing Terylene fibre are described. Crease-recovery is shown to be affected by total fabric sett and, for fabrics made from filament yarn, by twist and float length. No large differences are observed when the times and conditions of treatment on worsted and woollen finishing machinery are modified, but recovery is shown to depend upon the temperature at which fabric is heat-set.
