After washing fabrics can be treated with a conditioning agent, for example a fabric softener. In one method of treatment a substrate impregnated with a conditioning agent is contacted with the washed fabrics in tumble drier. The agent is transferred to the fabric during the repeated contacts between the substrate and fabric. The invention is the use of a substrate having a more dense structure at the outer surface. This more dense structure, which can be formed from laminated foam polymers, reduces the release of the agent so that the release is more even over a number of cycles.

Product for treating fabric

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.

A product adapted for the treatment of cellulosic fabric comprises a container having at least two compartments for holding two or more fluent substances separate from one another but adapted for dispensing the substances simultaneously, and having in one compartment a resin precondensate and in another compartment a latent acid catalyst. The product is used to make aqueous solutions of both resin precondensates and latent acid catalysts for fabric treatment, whilst keeping the ingredients separate until required for use.
