Abstract:
Disclosed are multi-ply embossed tissue products having improved softness, strength, embossment clarity and/or embossment height compared to prior art embossed tissue products. The multi-ply tissue products may comprise an embossed tissue ply having a basis weight less than about 25 grams per square meter (gsm) and relatively deep embossments, such as an embossment height from about 500 to about 1,000 μm and relatively narrow bottom portions compared to top portions. The combination of these elements provides an aesthetically pleasing and well-defined embossment, while improving important tissue product properties such as sheet and roll bulk and softness.
Abstract:
The creped multi-ply tissue products are durable, smooth and have low levels of Slough. In certain instances, the creped multi-ply tissue products are produced using a creping composition comprising a non-crosslinked latex polymer. The creped multi-ply tissue products may have a geometric mean tensile (GMT) from about 700 to about 1,500 g/3″, a basis weight from about 45 to about 60 gsm and a Slough less than about 2.00 mg, such as from about 0.10 to about 2.00 mg. The inventive tissue products also have good durability, such as a Durability Index from about 10.0 to about 20.0, smooth surfaces, such as a TS750 value from about 15.0 to 40.0 and low stiffness, such as a Stiffness Index less than about 10.0.
Abstract:
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.
Abstract:
An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern includes the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.

A cylinder system for tissue paper lamination comprising an embossing cylinder (22), which includes a combined DESL (1) and Point to Point (2) embossing, and for this purpose, higher elements (23) are provided for DESL process, and lower elements (24) for Point to Point process, such elements forming several relieves on paper surface and can compose figures, ribbing and all sorts of drawings.
Abstract:
A fibrous product includes at least one top ply with an embossing pattern forming pillow-like chambers at least partially surrounded by first embossing protuberances; at least one middle ply embossed in register with the at least one top ply so that second embossing protuberances of the at least one middle ply nest into the pillow-like chambers of the at least one top ply; and at least one bottom ply in register with the at least one top ply and the at least one middle ply being bonded to both the at least one top ply and the at least one middle ply at bonding regions. The at least one bottom ply includes non-embossed areas and embossed areas provided with a micro-embossing pattern, whereby the unembossed areas of the bottom ply are in register with the top ply and the middle ply.

Abstract:
A method relates to the production of paper rolls for examination tables, obtained from a tape (100) of embossed paper, having two layers (10, 20), joined together. The band (100) is obtained in known way from two continuous webs (1, 2), subjected to subsequent steps of embossing, glue (C) application, coupling and stabilization. The method includes applying measured quantities of a sanitizing and/or disinfectant substance (S) between the two layers of embossed paper (10, 20) before their joining; preferably, the substance (S) is applied to the same continuous web (1) that is aimed at receiving the glue (C), after the embossing step and contemporarily with the glue (C) application, by spot-application of a mixture (M) in aqueous solution containing suitable percentage of the glue (C) and sanitizing substance (S) to the tops (11A) of the embossing relieves (11.) In this case, the application means (240) for sanitizing substance (S) are formed by the same means (220) for applying the glue (C).
Abstract:
Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together in discrete sections to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a “bag-in-a-bag” type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.
Abstract:
A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.
