Rigid foam-core construction underlayment is formed to have one broad side covered by a flexible substrate that carries a series of spaced-apart, discrete regions (such as islands or spaced lanes) of resin, each resin region carrying a respective field of male touch fastener elements extending away from the substrate and exposed for engagement, such as by fibers on an inner surface of exterior construction material, such as a roofing membrane.

A method for manufacturing a single- or multi-layered substrate, which is suitable for a floor panel, where, for forming a substrate layer, thermoplastic material is strewn, for example, onto a transport device. The strewn thermoplastic material is consolidated under the influence of pressure and/or heat, preferably in a press device, where the thermoplastic material to be strewn comprises micronized material.

A composite layer for use in a bedding product such as a mattress and a method of manufacture are disclosed. The composite layer generally includes an extruded three dimensional fibrous layer and a foam material, e.g., polyurethane, latex or the like, disposed within the fibrous layer and occupying at least a portion of the free volume in the layer. Also disclosed are processes for manufacturing a foam-fiber composite.

The present invention provides a method for manufacturing a foam molded body, including: a setting step of inputting a foam matrix material into a mold that is not affected by microwaves, wherein the foam matrix material includes a plurality of half-foamed granules of thermoplastic polyurethanes (TPU) and at least an embedded component, and the embedded component is of a material or its product that is not affected by microwaves; and a foaming step of heating the mold by microwaves, wherein the half-foamed granules in the mold are affected by microwaves such that the temperature thereof are raised to effect foaming and the granules are squeezed with each other, and the embedded component is therefore squeezed and fixed, so as to form a foam molded body embedded with an embedded component after cooling and demolding.

Method for manufacturing a single- or multi-layered substrate (9), which is suitable for a floor panel (1), wherein, for forming a substrate layer (9A-9B-9C), thermoplastic material (23A-23B-23C) is strewn, for example, onto a transport device (25), and this strewn thermoplastic material is consolidated under the influence of pressure and/or heat, preferably in a press device (27), characterized in that the thermoplastic material (23A-23B-23C) to be strewn comprises micronized material.
