    摘要： 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 percent 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 into 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 or said metals to control the total migration of the resin binder during such deposition.

    摘要： A method of bonding porous, absorbent fibrous materials which comprises applying thereto a water-based synthetic resin binder composition having a pH in the range of from about 2 to about 6 and comprising from about 0.1% to about 60% by weight of a synthetic resin; from about 0.1% to about 6% by weight of a water-soluble salt of zirconium or aluminum; and from about 0.05% to about 3% by weight of a water-soluble, polymeric, polyhydroxy compound which does not contain interfering acidic chemical groups; substantially immediately diluting the synthetic resin binder composition whereby a zirconium or aluminum cation is released from the water-soluble salt to substantially immediately destroy the stability of the synthetic resin binder composition and to coagulate the resin with a minimum of further migration and bond the porous, absorbent fibrous materials; and drying the porous, absorbent fibrous materials. The invention also relates to the resulting bonded, porous, absorbent fibrous materials.
