  • Patent number: 5110525
    Abstract: A method for manufacturing a substantially rigid water-dispersible article includes the step of mixing together an ionic water-soluble film-forming polymer, a non-ionic water-soluble film-forming polymer, a chemically purified finely divided highly bleached cellulose, and glass fiber wool. Water is added to the dry mixture to form a dough which is subsequently molded into the desired form and dried while being maintained in the molded form. A filler or extender such as talc or paper pulp may be added prior to the molding step. In addition, a wetting agent may be added to accelerate rewetting and dispersal of the article upon disposal thereof, while a hydrophobic composition may be added to the dough to form a water repellant surface layer or film during drying of the molded article.
