  • Thin-skin stabilization of pads of fluffed pulp
    Patent number: 4233345
    Abstract: A method is provided for the stabilization of a high loft, low density, air-laid pad of short length fibers by the formation of a thin, reinforcing layer on a surface thereof. The film is formed by first pretreating a surface of the pad with a light spray (at a level not higher than about 15 cc per sq. meter of the pad) of a solution of a coagulating material for a resin dispersion, and then applying the resin dispersion to the pretreated surface and limiting its penetration into the pad by instant coagulation thereof.
