ABSTRACT:
A device for conditioning fabrics in the tumble-dryer comprises a powdered conditioning agent inside a permeable container, for example a sachet of paper, nonwoven fabric or plastics film, which in turn is inside an outer, substantially form-retaining, apertured container. The outer container is of a shape, for example, spherical, which allows ready movement among the tumbled fabrics. As it moves, the article gives more uniform and efficient conditioning than articles in the form of a sheet substrate impregnated with a solid conditioning agent.
