  • Patent number: 5002814
    Abstract: The invention relates to superabsorbent fibre flocks comprising a core of absorptive polymer wherein short polymer fibres have been embedded, such short polymer fibres protruding at least partially from the core. Such superabsorbent fibre flocks can be produced by binding absorbent polymer particles to each other and to the polymer fibres with the aid of a bonding agent and by grinding the fibre flocks thus obtained to the required particulate size. The superabsorbent fibre flocks according to the invention can be used to advantage in sanitary products, especially in baby diapers, menstrual pads and incontinence articles and have further application in separating water and aqueous components from hydrophobic liquids.
