Abstract
A product for treating, e.g. softening, fabric in a tumble drier has a perforated membrane and means for generating pressure in the product to cause a conditioning agent to exude through the perforations onto the surface of the product where it is removed for application to the fabric. The pressure may be caused by using a heat-shrinkable or a stretched elastomeric membrane and the product is preferably attached inside the drier.
