  • Aluminium-salt impregnated fibres, a method for their manufacture, fluff consisting of such fibres, and the use of the fibres as absorption material
    Patent number: 5601921
    Abstract: Aluminum salt impregnated organic pulp fibers for use in absorption articles are disclosed. The fibers have an aluminum content of 3-100 g/kg based on the weight of dry pulp. The pulp fibers are in the form of fluff and, when disposed in a layer, exhibit increased absorption rates and improved dispersion of liquid in horizontal and vertical directions. The fibers, in the form of an aqueous suspension, are impregnated with aluminum salt in aqueous solution at a pH of 5-11, preferably 8.5-9.5 and most preferably at a pH of 9. Impregnation may optionally be carried out in the presence of a silicate.
