Abstract:
Provided is a carpet tile produced by using as a backing material a mixture which contains a solvent deasphalted asphalt and a copolymer of an olefin and a polar monomer, or a mixture which contains an amorphous polyolefin in addition to the above components. After applying the mixture as a hot melt to the back of carpet material, the backed carpet material is cooled and then cut or punched to produce the carpet tile.
Abstract:
A CARPET IS FORMED BY ADHERING A SECONDARY BACKING TO A PRIMARY BACKING WITH A THIXOTROPIC POLYURETHANE COMPOSITION SO THAT THERE IS SUBSTANTIALLY COMPLETE SATURATION OF THE BUNDLE WRAP WITH THE COMPOSITION WITHOUT PERNETRATION THROUGH THE PRIMARY BACKING. THE COMPOSITION CONTAINS WATER, A POLYOL WITH A HYDROXYL NUMBER LESS THAN 100, A DIISOCYANATE, A FILLER AND A CATALYST AND HAS AN INITIAL VISCOSITY OF BETWEEN 30,000 AND 1008000 CPS. #7 SPINDLE BROOKFIELD RVF, A POT LIFE OF BETWEEN 10 AND 60 SECONDS AND IS EXPANDABLE BETWEEN 100 AND 400 WHEN COMPLETELY REACTED. IT IS APPLIED TO THE UNDERSIDE OF THE PRIMARY BACKING WITH A DOCTOR KNIFE AND HEATED. A SECONDARY BACKING IS APPLIED TO THE UNCURED COMPOSITION AFTER IT IS SPREAD ON THE PRIMARY BACKING AND THE RESULTANT LAMINATE IS SUBJECTED TO PRESSURE PRIOR TO CURING TO DISINTEGRATE SUBSTANTIALLY ALL OF THE CELLS IN THE POLYURETHANE.
Abstract:
The present invention pertains to a method to produce a tufted carpet, comprising tufting yarns into a primary backing thereby forming an intermediate product, and mechanically fixing the yarns to the backing by applying a binding constitution to the back of the carpet, wherein the binding constitution used is a thixotropic constitution comprising a cross linkable plant oil and a curing agent, the method comprising applying the thixotropic constitution as a layer to the back of the intermediate product and activating the curing agent to induce cross-linking of the plant oil.
Abstract:
The present invention relates to a linoleum-based multilayer surface covering (1) comprising a linoleum-based layer (2) and a first and second backing layers (3, 4), said first backing layer (3) being a jute layer facing said linoleum-based layer (2), said second backing layer (4) being a polymer-based layer facing said jute layer.
Abstract:
This invention relates to a composite floor covering having a lower cushioning layer, at least one dimensionally stabilizing intermediate layer, and an upper layer of a decorative fabric. At least the upper surface of the decorative fabric has a protective polymeric coating. The floor covering has a resiliency of no greater than about 55 % and a density of at least about 10 lbs/ft .
