Abstract
A method for producing an absorption body, notably for use in cases of female incontinence which include forming a core by dry depositing a layer of hot meltable thermoplastic fibers and a highly absorbing pulverulent material, e.g. a cross-linked polymer prepared from a methacrylic monomer, on a porous sheet, subjecting the layer to heat treatment to form a stable three-dimensional fiber network and cutting or milling several preferably rectilinear, deep channels in the core surface.
