Products by Upcycling Landfill Waste Streams
20200362172 · 2020-11-19 ·

Fossil-fuel and rubber-derived waste stream conversion to composite lumber substitutes or barrier members; the composites having material properties and uses of greater value than the solid waste stream components separately or together. Preferred combinations including waste materials derived from waste carpet, waste tires, and waste bituminous roofing shingles, all enormous problems for landfill disposal. In a range of formulation ratios, when combined with a binder, new and marketable products are made from solid waste. Improved resistance to rot, to water, and to weathering is exhibited in synergy with improved compressive and flexural strength, enabling production of a wide variety of useful and environmentally-friendly structural products, for example. Product weight and strength can be engineered to suit and may be structural members for architectural, engineering or agricultural use. Advantageously, the new products themselves can be re-usedby an end-of-life process for making more new products, achieving the capacity to make and remake multigenerational products from solid wastes and to reduce loading of landfills.

Carpet waste composite

A composite material is produced from carpet waste and a binding agent, in intimate association, and may also include wood fiber or chips and/or other additives. A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material.

Methods to manufacture a textile product

The present invention pertains to a method to manufacture a textile product comprising a first sheet having a width and a length, and polymer yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polymer yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, transporting the sheet in a direction parallel to its length along a heating element, the heating element being directed to the second surface of the sheet, heating the second surface with the heating element to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the method comprises transporting the sheet in contact with the heating element, wherein the heating element is a stationary rigid plate-like element having a width corresponding to the width of the sheet, and a length that extends parallel to the length of the sheet, the plate being curved in its length direction, wherein the outer circumference of the plate is contacted with the sheet. The invention also pertains to a method to use a textile product obtained with the new method and a device for applying the said method.

LOW WEIGHT MODULAR CARPET COMPONENTS AND METHODS OF MAKING THE SAME
20200308762 · 2020-10-01 ·

A low-weight carpet tile and process for making the same, wherein the carpet tile comprises a facecloth having a plurality of face yarns tufted through a primary backing, an extruded polymer secondary backing layer, and a reinforcing scrim layer partially embedded within the extruded polymer secondary backing layer. The top surface and bottom surface of the carpet tile are defined by the facecloth and the reinforcing scrim layer, respectively. A polymer-based resin is extruded onto the facecloth to form an at least substantially uniform secondary backing layer, and the reinforcing scrim layer is laid onto the extruded polymer secondary backing layer while the extruded polymer secondary backing layer remains above a softening temperature for the resin. The entire multi-layer web is then passed through a nip to embed the reinforcing scrim layer into the extruded polymer secondary layer, and the entire web is chilled.

WOVEN CARPET TILES AND METHODS OF MAKING THE SAME

A carpet tile and process for making the same, wherein the carpet tile comprises a woven facecloth with an applied latex or hot-melt adhesive precoat, an extruded polymer backing layer, and an optional polyester cushion, comprising a reinforcing scrim layer within a polyester layer. The top surface and bottom surface of the carpet tile are defined by the facecloth and the polyester cushion or extruded layer, respectively. A polymer-based resin is extruded onto the pre-coat of the coated facecloth to form an at least substantially uniform backing layer, and the polyester cushion may be laid onto the extruded polymer backing layer while the extruded polymer backing layer remains above a softening temperature for the resin. The entire multi-layer web is then passed through a nip to embed the reinforcing scrim layer into the extruded polymer backing layer, and the entire web is chilled.
