Abstract: A fabric is formed of yarns having soiling-hiding and soiling-prone characteristics which are visually distinct one from the other in the surface of the fabric once the fabric has been soiled. The soiling-prone yarns comprise yarns formed of multi-lobal fibers or filaments where the soiling particles collect in the cavities of the lobed surfaces. Preferably, the soiling-hiding yarns are formed of hollowfil synthetic fibers or filaments. By embedding one or more yarns of the soiling-prone type in the fabric, e.g., carpet, the yarns become differentially visually distinctive relative to one another upon soiling of the fabric.

Abstract: A fabric is provided having discrete surface portions of a primary backing and tufted yarns exposed on the technical face of the fabric. To form the fabric, the yarn feed controlled by servomotors is adjusted in increments to rob back yarn sufficient to pull out the previously tufted loops in selected portions of the fabric, leaving the primary backing portion of the pulled-out loops exposed on the technical face. By the selection process, random or patterned tufted portions and exposed primary backing surface portions are provided on the technical face of the fabric.

Abstract: A covering for a floor, wall or ceiling surface includes tiles each having first and second discrete tile sections. The first section includes a primary backing exposed on one side of the tile forming a first discrete exposed surface portion and a plurality of yarns tufted into the primary backing with cut or loop yarns on the back side of the primary backing leaving backstitches forming a second discrete exposed surface portion of the first section. The primary backing and backstitches form the first and second surface portions, respectively, of the first section with aesthetic characteristics different from one another. The second section of the tile is formed of one of a woven fabric, a non-woven fabric and a tufted pile and which second section forms the remaining portion of the exposed surface of the tile.

Abstract: By utilizing specially processed waste carpeting as a filler in the production of carpet backcoating, roofing materials, or other similar products, the amount of waste carpeting that is landfilled or otherwise disposed of is significantly reduced as is the need for mining the mineral fillers. Waste carpeting (post-consumer and/or waste from new carpet manufacture) containing calcium carbonate and a thermoplastic resin is collected and size-reduced to a size corresponding to the size of calcium carbonate typically used as a filler. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting).
