    Abstract: Bonded fibrous nonwoven textile fabrics having excellent strength and textile-like softness, drape and hand which are intermittently bonded with synthetic resins in predetermined print patterns of binder areas having a relatively high, uniform concentration of from about 50 to about 120 percent by weight of resin binder in the binder areas, based on the weight of the fibers therein, said binder areas having very sharply defined borders or edges with a minimum of binder feathering thereat whereby the optical density of the bonded fibrous nonwoven textile fabric very sharply increases from substantially zero to a maximum of at least from about 0.6 to about 1.0 or greater in a distance of less than about 1 mm. (0.04 inch), and methods of depositing such synthetic resins from colloidal aqueous dispersions thereof onto wet fibrous webs to form the bonded fibrous nonwoven textile fabrics, comprising the use of (1) metal complex coordination compounds and (2) synthetic resins and/or surfactants, at least one of which contains a specific coordinating ligand capable of being affected by ions of said metals to control the total migration of the resin binder during such deposition.

    Abstract: Methods of recovering reusable fibers from mixtures of waste fibers and/or fabrics and synthetic, cross-linked polyacrylate resins which comprise: (1) heating a mixture of waste fibers and/or fabrics and synthetic, cross-linked polyacrylate resins in an aqueous saponifying solution containing an alkali metal hydroxide and a water-soluble salt containing a monovalent cation, which solution saponifies the synthetic, cross-linked polyacrylate resins and initiates their decomposition or solubilization without undesirably swelling the same; (2) treating the mixture of waste fibers and/or fabrics and synthetic, cross-linked, saponified, polyacrylate resins in an aqueous washing solution containing a water-soluble salt containing a monovalent cation to remove alkali therefrom; and (3) washing and recovering the reusable fibers from the mixture of waste fibers and/or fabrics and decomposed or solubilized synthetic, cross-linked polyacrylate resins.

    Abstract: Stable, aqueous, colloidal synthetic resin compositions comprising: (1) from about 0.1 percent by weight to about 60 percent by weight of a colloidal synthetic resin; and (2) from about 0.01 percent by weight to about 2 percent by weight based on the dry solids weight of the colloidal synthetic resin of a reaction product of a zirconyl complex salt and a high molecular weight, water-soluble, polymeric, polycarboxy-containing thickening resin; said zirconyl complex salt having the formula R3ZrOR''A3 wherein R is ammonium, hydrogen, or an alkali metal; Zr and O are zirconium and oxygen; R'' is ammonium, hydrogen, or an alkali metal; and A is a divalent anion; and methods of applying the synthetic resin compositions to porous absorbent materials and controlling the migration or spreading thereon or penetration thereinto by applying the synthetic resin compositions to the porous absorbent materials and substantially immediately diluting the synthetic resin composition to substantially immediately coagulate and precipitate the synthetic resin composition.
