A method for producing a resin-bonded nonwoven fabric comprising forming a fibrous web, compressing the web to provide fiber to fiber contact, applying a polymerizable binder to the fibrous web and treating the web with the binder thereon with ionizing radiation to produce a resin bonded nonwoven fabric.

Method for producing bonded nonwoven fabrics using ionizing radiation

Improved stable, aqueous resin compositions comprising from about 0.1% to about 60% by weight on a solids basis of a synthetic resin and from about 0.01% by weight to about 6% by weight, based on the weight of the synthetic resin, of an aluminum chlorhydroxide complex from the group consisting of: (a) aluminum chlorhydroxides; (b) reaction products of aluminum chlorhydroxides and polyhydroxy compounds; (c) reaction products of aluminum chlorhydroxides and monocarboxylic acids; (d) and mixtures thereof; and methods of utilizing the same.

Resin latex compositions

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% 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.

Bonded nonwoven fabrics

Synthetic resin compositions comprising: (1) a synthetic resin; (2) a polyvalent metal complex coordination compound; and (3) a water-soluble, ionically-active ammonium or alkali metal salt of an acid capable of being chemically converted into an ionically-inactive polyvalent metal salt of said acid by chemical reaction and precipitation or sequestration of said polyvalent metal salt.
