摘要： Disclosed are non-treated, creped tissue webs, and tissue products produced therefrom, having low stiffness and surface lint. The inventive products may be produced by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue product. The non-crosslinked latex polymer creping composition does not negatively affect stiffness such that the products generally have a Stiffness Index less than about 5.0, such as from about 2.5 to about 5.0.

摘要： Corrugated paper includes first and second sheets of paper; and a layer of structured paper disposed between the first and second sheets of paper. The layer of structured paper includes cells, in which at least some of the cells are negative Poisson's ratio (NPR) cells. Each NPR cell includes top and bottom walls, and side walls angled inwards toward a central portion of the NPR cell, such that application of a compressive force between the top and bottom walls of the NPR cell causes a lateral dimension of the NPR cell between opposite side walls to decrease. The NPR cells exhibit a Poisson's ratio of between 0 and −1.

摘要： Embossed tissue products having improved strength and softness are disclosed. The products as described have a continuous curvilinear emboss element which carries discrete emboss elements, thereby providing the product with the softness and handfeel benefits associated with the long linear elements, but the visual appearance of discrete emboss elements.

摘要： The embossed multi-ply tissue products have improved bulk, softness, strength, embossment clarity and/or embossment height. The multi-ply tissue products comprise a first tissue ply having a plurality of embossments arranged in an open first pattern such as open, continuous line elements, which may be substantially oriented in the cross-machine direction (CD). The second ply of the multi-ply tissue product have a plurality of micro-embossments disposed in a second pattern. The first and second embossing patterns are such that when the first and second plies are joined to form the product the first and second patterns are not in registration with one another.

摘要： There is provided a container having at least one wall composed of a corrugated board comprising an inner linerboard, an outer linerboard and a fluting arranged between the inner linerboard and the outer linerboard, characterized in that the hygroexpansivity in the CD of the inner linerboard is higher than the hygroexpansivity in the CD of the outer linerboard, wherein hygroexpansivity is measured according to ISO 8226-2:1990.

摘要： A method of making an absorbent structure including mixing ultra-high molecular weight (“UHMW”) glyoxalated polyvinylamide adducts (“GPVM”) and/or high molecular weight (“HMW”), glyoxalated polyacrylamide and/or high cationic charge glyoxalated polyacrylamide (“GPAM”) copolymers and high molecular weight (“HMW”) anionic polyacrylamide (“APAM”) with the furnish during stock preparation of a wet laid papermaking process.

摘要： Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3″. Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.
