ABSTRACT A liquid absorbing pad, in particular for use in hygiene articles and sanitary products, such as diapers, bed pads, sanitary napkins, pads for incontinence, panty shields, nursing pads or the like, is produced in a dry and direct process on the basis of wet-strength and/or coated paper waste, especially originating from the production of food packages, milk carton packages, deep-freeze packages, disposable tableware and the like. The waste is cut and defibrated, and during the defibra- tion or just before it a maximum of 25% by volume, based on the volume of the paper waste, of a mixture of water and a surfactant is added to reestablish the absorption capacity of the fibres. Starting materials otherwise difficult to process can thus be used in a dry and direct process.
