20130273297 | Fabric-Faced Floor Coverings with Micro-Spring Face Structures - The present invention is directed to multiple-layer composites suitable for use as floor-coverings in the form of cut tiles or broadloom sheets, providing a durable and highly stable structure that can lay flat and remain flat with variations in temperature and humidity and provide a durable and yet soft textile face. The composite comprises a laterally-compressible fabric face bonded with an adhesive layer to a highly conformable stress-absorbing cushioning layer. The face fabric comprises closely packed looped yarns reciprocating between the top and the bottom of the fabric, protruding into the adhesive layer and emerging from the adhesive layer to the surface forming micro-spring structures. The weight, properties, density and level of penetration of adhesive are controlled to maintain lateral compressibility for the entire composite and avoid warping. | 10-17-2013 |
20100279057 | Fabric-Faced Composites and Methods for Making Same - The present invention is directed to multiple layer composites suitable for use as wall and floor coverings, among other uses, that provide a strong durable structure and a soft textile or fabric face. The composite includes a face layer bonded to an adhesive layer such that the adhesive layer penetrates into the face layer. The face layer can have legs extending there from, and such legs are anchored by the adhesive layer to provide stronger attachment between the adhesive layer and the face layer. A backing layer may also be provided in contact with the adhesive layer such that the adhesive layer also embeds into the backing layer, and the legs extending from the face layer may penetrate into the backing layer. | 11-04-2010 |
20090280710 | Needlepunched nonwoven with centrally-located binder - The present invention concerns a process for forming a wearable and functional fabric from a composite material comprising a nonwoven face layer containing a plurality of fibers, and at least one thermoplastic binder layer disposed underneath. The fibers are initially arranged in a generally planar web and subsequently needlepunched through at least one binder layer. The fiber layers can also be placed on both sides of one or more centrally-located binder layers, and further reinforced with scrims. In an innovative aspect of the invention, the composite is heated under low and uniform pressure to remove thermal stresses, resulting in at a least one relatively smooth face that can be coated to form a wearable fabric, e.g., artificial leather, odor absorbing fabric, and the like. | 11-12-2009 |
