Abstract
In the practice of the invention, a multi-ply paper product or tissue having hardwood layers on the outside and on the inside provides reduced amounts of undesirable sloughing. The multi-ply product includes at least two plies, with three layers in each ply. Hardwood layers, such as for example eucalyptus-containing fiber layers, are provided on the outside surfaces of each ply and also on the interface of one or more plies. The resulting paper product may exhibit reduced sloughing, with little or no sacrifice in softness. A product having two, three, four, or more plies is shown.
Claims
exact text as granted — not AI-modified1 - 23 . (Cancelled)
24 . A multi-ply facial tissue comprising:
a first ply, said first ply comprising a first layer comprising hardwood fibers, a second layer comprising hardwood fibers, and a third layer comprising softwood fibers, wherein said third layer of said first ply is positioned between said first and second layers of said first ply; and a second ply, said second ply comprising a first layer comprising hardwood fibers, a second layer comprising hardwood fibers, and a third layer comprising softwood fibers, wherein said third layer of said second ply is positioned between said first and second layers of said second ply; wherein said multi-ply facial tissue has a basis weight from about 10 to about 80 grams per square meter, wherein said second layer of said first ply is positioned adjacent to said first layer of said second ply such that said first layer of said first ply defines an outer surface of the tissue, and wherein said outer surface is creped.
25 . A method of forming a multi-ply tissue product comprising:
forming a first ply that contains a first layer comprising hardwood fibers, a second layer comprising hardwood fibers, and a third layer comprising softwood fibers, wherein said third layer of said first ply is positioned between said first and second layers of said first ply; adhering said first layer of said first ply to a creping surface; creping said first layer of said first ply from said creping surface; forming a second ply that contains a first layer comprising hardwood fibers, a second layer comprising hardwood fibers, and a third layer comprising softwood fibers, wherein said third layer of said second ply is positioned between said first and second layers of said second ply; and positioning said second layer of said first ply adjacent to said first layer of said second ply such that said first layer of said first ply defines an outer surface of the multi-ply tissue product.Join the waitlist — get patent alerts
