Multi-ply absorbent wiping product having relatively inextensible center ply bonded to highly extensible outer plies

A method for producing a multi-layered absorbent paper wiping product having a relatively inextensible central ply intermittently bonded to highly extensible outermost plies, comprising the steps of:

• a. imprinting a continuous pattern of water-resistant, reinforcing resin on at least one side of a central ply of tissue paper having less than about 10 percent total stretch, said pattern covering between about 15 and about 55 percent of the total surface area thereof;
• b. reducing the total moisture content of said resin-reinforced central ply to not more than about 10 percent;
• c. embossing each outermost ply of tissue paper having between about 15 percent and about 50 percent crepe to produce embossment points therein, said embossment points constituting between about 7 percent and about 50 percent of the total surface area thereof;
• and
• d. laminating said outermost plies to said central ply by bonding them to said central ply at points of embossment which are common to both of said outermost plies.

A method for producing a multi-layered absorbent paper wiping product having a relatively inextensible central ply intermittently bonded to highly extensible outer plies, comprising the steps of:

• a. imprinting a continuous pattern of water-resistant, reinforcing resin on at least one side of a central ply of wet strength tissue paper having less than about 10 percent total stretch, said pattern covering between about 15 and about 55 percent of the total surface area thereof;
• b. reducing the total moisture content of said resin-reinforced central ply to not more than about 10 percent;
• c. embossing each outermost ply of wet strength tissue paper having between about 15 and about 50 percent crepe to produce embossment points therein, said embossment points constituting between about 7 percent and about 50 percent of the total surface area thereof;
• d. laminating said outermost plies to said central ply by bonding them to said central ply at points of embossment which are common to both of said outermost plies;
• and
• e. momentarily crushing the laminated structure thus formed by calendering, thereby making its caliper more uniform and improving its overall softness and drape.

A method for producing a multi-layered absorbent paper wiping product having a relatively inextensible central ply intermittently bonded to highly extensible outermost plies, comprising the steps of:

• a. imprinting a continuous pattern of water-resistant, reinforcing resin of the self-crosslinking polymer variety on opposite sides of a central ply of wet strength tissue paper having less than about 10 percent total stretch at a rate between about 1.0 and about 4.0 pounds of resin solids per 3,000 sq. ft. per side, said pattern covering between about 15 percent and about 55 percent of the total surface area of each side thereof;
• b. reducing the total moisture content of said resin-reinforced central ply to between about 2 and about 10 percent prior to laminating said outermost plies of wet strength tissue paper having between about 15 and about 50 percent crepe to said central ply;
• c. producing embossment points constituting between about 7 and about 50 percent of the total surface area in each of said outermost plies by passing each of said plies between an elastomer-covered roll and one of a pair of synchronously driven, hard-surfaced embossing/laminating rolls;
• d. bonding said outermost plies to said central ply at embossment points common to each of said outermost plies, said common embossment points constituting between about 7 and about 50 percent of the total surface area thereof, with the reinforcing resin contained on said central ply by simultaneously passing all of said plies between said pair of synchronously driven, hard-surfaced, embossing/laminating rolls;
• e. momentarily crushing the laminated structure thus formed by calendering, thereby making its caliper more uniform and improving its overall softness and drape;
• and
• f. curing the self-crosslinking polymer resin contained in the laminated structure to increase its overall strength.
