Abstract: A laminate for making a flexible fastener. The laminate has according to the invention outer layers of nonwoven and parallel and spaced strips of an elastic film laminated between the outer layers. The outer layers are directly bonded to each other in regions between the elastic strips and there form inelastic regions of the laminate while regions each containing one of the strips form elastic regions. At least one of the outer layers is a sheer nonwoven. A color or pattern imprint is printed on the one outer layer over the elastic and inelastic regions.

A multiplicity of loops formed of polymer threads are knitted into only the cover layer and project from an outer face thereof.

Abstract: A laminate material web has two webs of nonwoven fabric that lie on the outside, and film strips of an elastic film disposed between them, in sections, whereby the nonwoven fabric webs are connected with one another in the regions between the film strips. The film strips are connected with the inner surfaces of the nonwoven fabric webs only at the two longitudinal edges, in each instance, both on the top and on the bottom, and the nonwoven fabric webs have weakenings running in the web direction, in the regions that cover the film strips. A method for the production of a laminate material web is also described.

Abstract: A fastener strip for diapers has a center part that is elastic in the longitudinal direction of the strip when the fastener strip is pulled, a non-elastic end part to which a hook element is attached, and a non-elastic connector part for attachment to a diaper. The end part and the connector part are attached to the center part. The center part has a layer of an elastic spun-bonded non-woven fabric, which possesses preferred stretching properties in the longitudinal direction of the strip. The spun-bonded non-woven fabric is made of filaments that have a filament core of a thermoplastic elastomer and a filament mantle of a non-elastic thermoplastic polymer, stretched by means of stretching the spun-bonded non-woven fabric.

Abstract: A method for producing an elastic laminate material web that has elastic and non-elastic regions and has non-woven fabric on both surfaces of the web. In between the two surfaces, there are film strips of an elastic film. One surface of the web consists of a planar non-woven fabric layer and is connected with non-woven fabric that is disposed on the opposite surface of the web in areas between the film strips. Each film strip is connected with a non-woven fabric layer to form a laminate strip. The laminate strips are glued to the planar non-woven fabric layer on their film side, and the non-woven fabric that is connected with the planar non-woven fabric layer between the laminate strips is in the form of non-woven fabric strips that run parallel to the laminate strips. The non-woven fabric strips overlap the non-woven fabric layer of the laminate strips in edge regions of the laminate strips.

Abstract: An elastic nonwoven laminate is made by applying spaced zones of adhesive to a face of an elastic film such that adhesive-free zones are left between the adhesive zones. This elastic film carrying the adhesive zones is advanced in a travel direction, and an unconsolidated fleece nonwoven layer of filaments is applied to the face of the advancing film such that the fleece layer adheres to the film at the adhesive zones. The fleece layer can be formed by extruding a multiplicity of fibers or filaments and depositing them directly on the face of the film. Alternately they can be deposited on a conveyor that transports the fleece to the film and presses it against the film. Either way, the fleece layer is not consolidated and the fleece layer is not compacted prior to application to the glued side of the film.

Abstract: A loop-side composite element of a hook-and-loop fastener has an air-permeable textile substrate having an outer edge and a face and an air-permeable and loop-forming functional textile layer generally congruent to and overlying the face of the substrate. An annular adhesive strip extends along the outer edge, is bonded to the face of the functional layer and a confronting face of the substrate, and defines on the face of the substrate an open center region. A plurality of adhesive spots spaced apart on the face of the substrate in the open region are each bonded to the face of the substrate and to the confronting face of the functional layer. The faces are free of adhesive and not bonded to each other in the region between the spots. The gluing or laminating may be accomplished using a reactive PUR adhesive or a hot-melt adhesive.

Abstract: The invention relates to an elastic laminate. The laminate is made from a co-extruded elastic film, comprising an elastomeric support layer, at least one cover layer and at least one textile outer layer made from a non-woven. The cover layer has a low layer thickness by comparison with the support layer. The outer layer is laminated onto the cover layer. According to the invention, the cover layer is made from an elastomeric material, with essentially the same expansion properties as the material of the support layer and contains additives for modification of the surface properties.

Abstract: An elastic composite strip has a longitudinally elongated substrate strip having a pair of opposite faces and formed of an elastomer that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely. A respective soft knit fabric cover strip that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely extends longitudinally on each of the faces. Respective arrays of longitudinally spaced and transversely extending lines of adhesive are bonded to the faces and to filaments of the respective cover strips.

Abstract: A laminate material for hook-and-loop closures, comprising a carrier film and a textile substrate laminated onto the carrier film. The textile substrate has loops on its surface that are suitable for connecting with hook-and-loop hooks, wherein the carrier film and the textile substrate are not connected over their entire area. A method for producing a laminate material for hook-and-loop closures comprises applying an adhesive to a carrier film in a pattern that is composed of adhesive areas and adhesive-free regions, applying a material web of a textile substrate to the side of the carrier film provided with adhesive to form a two-ply web, the textile substrate having loops on its surface that are suitable for connecting with hook-and-loop hooks; and passing the two-ply web through a roller nip of a pair of rollers, which presses the carrier film and the textile substrate together.

The cover layer consists of a fiber non-woven fabric, which contains fibers of an elastic polymer and fiber components of a non-elastic thermoplastic polymer, which have been stretched in the preferred elongation direction by means of an elongation of the fiber non-woven fabric. There is also a method for making the laminate material.
