1520746 Fibre coated hydrogel particles UNION CARBIDE CORP 2 July 1975 [29 July 1974] 27795/75 Heading B2E Absorbent hydrogel particles which may be inorganic, e.g. silica gels or organic, e.g. cross linked polymers many of which are specified are coated with fibrous materials which may be synthetic, e.g. nylon or rayon flocs or natural, e.g. wood pulp fibres, cotton linter flocs or cellulose fibres, or a mixture thereof. The particles may be treated to achieve particle adhesion, e.g. by heat softening or fluid treatment, e.g. with steam or water. Cross linking may be achieved by ionising radiation, e.g. X rays or an electron beam or by chemical means. The coated particles may be incorporated in diapers, catamenial devices and incontinence pads.
