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.

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 present invention relates to a compressor arrangement with at least two compressors, wherein the compressor arrangement includes an intake chamber directly provided upstream of the at least two compressors together on the suction side.
摘要:
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.
摘要:
The invention relates to a water separator for air-conditioning systems, preferably for aircraft air-conditioning systems, comprising a swirl generator, a housing surrounding it, a separation chamber arranged around the housing for the collection of the water separated at the inner wall of the housing, which opens in a separation sump, and at least one opening provided toward the separation chamber in the housing. In accordance with the invention, the separation chamber is made in multistage form, with the first stage of the separation chamber serving the accumulation of the water drops, the second stage of the separation chamber serving the deposition of the accumulated water drops and the third stage of the separation chamber serving the extraction of the air mass flow.
摘要:
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.
摘要:
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.
摘要:
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.
