Abstract
An investigation is described in which the reduction in wrinkle-recovery of wool–polyester-fibre fabrics caused by the use of carrier during dyeing was studied. Only the polyester-fibre component absorbed appreciable amounts of carrier, and the extent of the reduction in wrinkle-recovery depended on the type and amount of carrier retained in the polyester fibre after dyeing. The effectiveness of finishing treatments in removing carrier and restoring wrinkle-recovery is discussed in terms of changes in the glass-transition temperature.
