摘要:
Absorbent article comprising a loop member for a hook and loop fastener. The loop member comprises a knitted fabric which is adhesively attached to a carrier. The adhesive pattern for attaching the knitted fabric onto a carrier has a first plurality of adhesive stripes extending substantially in the warp thread direction of the knitted fabric and a second plurality of adhesive stripes extending substantially perpendicular to the first plurality of adhesive stripes.

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.

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 loop element for a hook-and-loop fastener has a substrate layer of a nonwoven having an outer face, a fleece cover layer on the outer face of the substrate layer, and an adhesive layer on the outer face securing the cover layer to the substrate layer. A multiplicity of loops formed of polymer threads are knitted into only the cover layer and project from an outer face thereof.

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.

A laminate material element (1) for a hook and loop closure, particularly a diaper closure, has a carrier film (2) and a textile material (3) laminated onto the carrier film (2), which has a surface structure that is suitable for forming a connection with the hooks of a hook and loop closure. The carrier film (2) and the textile material (3) are bonded together over their entire surface in an edge region that extends along the edges of the laminate material element and has the shape of a frame. A bond between the carrier film (2) and the textile material (3) that does not cover the entire surface is provided in the region within this frame.

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.
摘要:
A method for the production of a fleece laminate material that has elastic regions and non-elastic regions. In the method, parallel strips of elastic laminate are laminated in between two webs of nonwoven material, at a distance from one another and the nonwoven webs are directly bonded to one another, in the regions between the strips, and form non-elastic regions. The segments of the fleece laminate material that contain a strip, in each instance, form elastic regions. According to the invention, the elastic laminate has a tacky elastomer core layer and at least one non-blocking outer layer of nonwoven material, applied to the tacky core layer.
摘要:
Process for producing an elastic multilayer web of material consisting of a flexible elastic backing film made of a thermoplastic elastomer and a web of nonwoven material bonded in a crepe-like manner to both the top and bottom sides of the backing film, whereby the webs of nonwoven material are welded together and the weld bonds are distributed over the web of material in the form of a grid arrangement of spot welding points and at the same time yield areas of increased air permeability through the web of material. The following process steps are carried out: a) guiding and stretching the backing film to at least (100+a) % of the unstretched length, b) separately guiding and stretching two webs of nonwove (11 and 12) to certain dimensions (100+b) % and (100+c) % while maintaining the following conditions: b
摘要:
A method for the production of a laminate material for hook and loop closures, particularly for diaper closures, comprises laminating a textile material onto a carrier film having a surface structure that is suitable for forming a connection with the hooks of a hook and loop closure. The textile material is not connected with the carrier film over its entire area, and the textile material forming the cover layer of the laminate material is brushed after lamination.
