11603613 · 2023-03-14 · ·

A non-woven sheet (10) comprises at least one zone of reinforcement (20a, 20b, 20c, 20d) in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern (22) comprising a plurality of geometric shapes (24), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X1), and over a width (l1, l2) strictly less than the width (l) of the sheet (10) measured in a lateral direction (Y1) orthogonal to the longitudinal direction (X1). The sheet (10) thus further comprises at least one non-reinforced zone (30a, 30b). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone (20a, 20b, 20c, 20d) under the effect of a given force exerted in a longitudinal direction of the sheet (10) is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet (10) may be used in particular for fabricating a laminated assembly.

Provided are a film including a matrix material, and a particle having an elastic modulus at 25° C. which is higher than an elastic modulus of the matrix material, in which the film has a region A at at least a part between the matrix material and the particle, and the region A contains a compound having a loss tangent of 0.1 or greater at 25° C.; and a laminate formed of the film.

Method and apparatus for assembling absorbent articles

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

CD extensible nonwoven composite

A nonwoven composite that has a dimension in a machine direction and a cross-machine direction is provided. The composite comprises a nonwoven facing positioned adjacent to an elastic film. The nonwoven facing contains a spunbond web that is formed by necking a base spunbond web. The base spunbond web includes a plurality of fibers generally oriented in the machine direction and exhibiting a machine direction tensile strength and cross-machine direction tensile strength. The ratio of the machine direction tensile strength to the cross-machine direction tensile strength is about 4:1 or more.

Metal-resin bonded member and method of manufacturing the same

An object is to provide a metal-resin bonded member that is easy to manufacture and has high bonding strength. The metal-resin bonded member includes a metal body having an iron oxide layer on the surface and a resin body bonded to the metal body via the iron oxide layer. The iron oxide layer has a thickness of 50 nm to 10 μm. The iron oxide layer comprises 60-40 at % Fe and 40-60 at % O at the outermost surface side. The iron oxide layer contains magnetite (Fe.sub.3O.sub.4). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850° C. in an oxidation atmosphere. The resin body is composed of polyphenylene sulfide (PPS). The bonding of the metal body and the resin body via the iron oxide layer can be carried out by insert molding, thermal adhesion utilizing friction heating, etc.
