IMPROVED EMBOSSED AND APERTURED LAMINATE FOR ABSORBENT ARTICLES AND THE LIKE
20180177643 · 2018-06-28 ·

A laminate with a fibrous nonwoven web first layer (20) bonded to a second layer (40) by way of a plurality of first layer embossments is disclosed. The first layer (20) further includes a plurality of apertures and an air gap between the first layer (20) and second layer (40). The laminate is well-suited for a wide variety of uses and in particular as a top sheet or liner material for absorbent articles such as, for example, diapers, training pants, feminine hygiene products, incontinence devices and wipes. Also disclosed is a process for forming such a laminate.

Bonding apparatus and method

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

Method And Apparatus For Making An Apertured Web

A disposable absorbent having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, is described herein. The topsheet is a two layer composite or laminate web having a first layer and a second layer. The composite or laminate has a first plurality of apertures and a second plurality of apertures, wherein the first plurality of apertures have sidewalls that extend in a first direction, wherein the second plurality of apertures have sidewalls that extend in second direction that is different than the first direction, and wherein the composite or laminate also includes a plurality of embossments which extend in a third direction opposite the first direction.

HOUSEHOLD TISSUE PAPER AND HYDROLYSABLE SHEET

Household tissue paper is obtained by applying a ply process to two or more sheets of base paper. First embossments and second embossments, arranged around the first embossments, are formed on an entire surface of the household tissue paper, a shape of a protruding part of each of the second embossments differing from a shape of a protruding part of each of the first embossments. Hence, because a contact area with an object to be cleaned or the like can be increased, it is possible to enhance surface strength of the household tissue paper being embossed and to enhance wiping performance.

SMOOTH AND BULKY ROLLED TISSUE PRODUCTS

The novel tissue products of the present invention are generally produced by calendering a tissue basesheet using at least one patterned roll. In one embodiment the patterned roll replaces the flat steel roll commonly used in calendering. The elements on the patterned roll provide a means of providing a nip having variable loading such that Z-direction variability in the web is reduced, yielding a smoother web, but without subjecting the web to excessive compression forces and preventing excessive caliper loss. Thus, webs converted according to the present invention tend to retain a greater percentage of their caliper and bulk when converted compared to webs converted using conventional calendering means.

Method and device for embossing relief structures

A method and device of embossing individually light-reflecting areas on a foil material, the method and device comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a first roller and a second roller, providing each of the first roller and second roller at their respective surfaces at least in a determined perimeter, respectively with a plurality of polyhedron-shaped positive projections and a plurality of negative projections complementary to the positive projections, whereby the plurality of positive projections are arranged according to a 2-dimensional grid. The plurality of polyhedron-shaped positive projections seamlessly and gaplessly join with those corresponding negative projections at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron-like shape in the foil. The method and device further comprise, for the purpose of providing a plurality of light-reflecting areas on the foil material, that are intended to reflect light in line with a table of reflectivity values for the 2-dimensional grid, according to an orientation and shape of each of the plurality of light-reflecting areas, and enabling a perception by the human eye of a user, of the intended reflected light on a determined wide viewing angle covered by reflected light from any of the light-reflecting areas, a step of adjusting for each of the plurality of light-reflecting areas to be provided, an orientation and shape of the corresponding positive projection in the 2-dimensional grid, that is intended to emboss the light-reflecting area.

EMBOSSED MULTI-PLY TISSUE PRODUCTS

The present invention provides an embossed multi-ply tissue product that is visually pleasing and has improved physical attributes. For example, the inventive multi-ply tissue products have reduced stiffness, such as a GM Flexural Rigidity less than about 600 mg*cm, improved absorbency, such as a Residual Water (W.sub.Residual) value less than about 0.15 g, and improved wet resiliency, such as a wet elastic strain ratio greater than about 32 percent.

Multi-ply tissue paper product and method for manufacturing the same

A multi-ply tissue paper product includes at least two plies made of tissue paper base-sheet with at least one outer ply being a structured outer ply produced by a structuring manufacturing method. The structured outer ply includes a microstructure pattern on substantially at least 80% of the structured outer ply surface. The microstructure pattern is applied by micro-embossing during a converting operation. The structured outer ply is chosen from a through air dried ply produced by a through air drying (TAD) manufacturing method; a dried ply produced by an advanced tissue molding system (ATMOS), or a dried ply produced by a structured tissue technology (SST) manufacturing method. The microstructure pattern includes a first series of protuberances having a density ranging from approximately 30 to 100 protuberances/cm.sup.2. The softness property of the structured outer ply is adjusted during a micro-embossing step.
