Abstract
Abstract A bead, useful in a fabric aqueous laundering process to in- part to the fabric, when dried, at least one of the properties i) softness, and ii) antistatic effect, comprises a porous substrate, and substance absorbed onto said substrate to produce at least one of said i) and ii) properties in the fabric. A barrier layer may be formed about said substrate and characterised as dispersing in laundry wash water; a solubilizing or dispersion aid such as a nonionic surfactant may be mixed with said substance and also absorbed onto the substrate; and a hardener may be mixed with said substance and also absorbed onto the substrate.
