Abstract:
The invention pertains to a method to produce a laminated carpet tile comprising providing a first polymer sheet having yarns fastened thereto, the first sheet having a first surface and a second surface, the yarns extending from the first surface, providing a second polymer sheet,laminating the second polymer sheet to the second surface of the first sheet at a temperature above the glass transition temperature of the first and/or second polymer sheet, cooling the laminated product to room temperature, and optionally cutting the laminated product into multiple sub-products,wherein the step of cooling the laminated product to room temperature includes cooling the laminated product to a temperature below the glass transition temperature of the first and/or second sheet while the laminated product is forced to take a curved constitution wherein the second sheet is positioned at the inner side of the curve.
Abstract:
The invention pertains to a method to manufacture a textile product comprising a first sheet having polyester yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polyester 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, contacting the second surface of the sheet with a surface of a hot body to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the second surface is actively cooled to force the temperature to be below the glass transition temperature of the polyester yarns within 60 seconds after the contacting of the second surface with the hot body. The invention also pertains to a device for applying this method.
Abstract:
The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.
Abstract:
The present invention pertains to a method for recycling a carpet product, the carpet product comprising a fibrous sheet comprising polymer yarns, wherein at least one surface of the sheet is provided with a layer of polymer adhesive, wherein the carpet product is a substantially pure polyester carpet product, wherein the polymer yarns comprise polyester having a molecular weight above 50,000 g/mol and a melting point between 180 and 300°C, the adhesive is a polyester adhesive having a crystallinity between 5% and 35% and a viscosity of 5-55 Pa.s at 150°C, the method comprising homogenising the carpet product by extrusion. The invention also pertains to recycled polymer obtainable by this method, to fibres comprising this recycled polymer material, to fibrous products comprising these fibres and to polyester adhesive.
Abstract:
The present invention pertains to a method to manufacture a textile product comprising a primary carrier sheet and yarns that form a pile thereon, the method comprising providing a woven web as the primary carrier sheet, stitching the yarns through the woven web to form the pile on a first surface of the web and loops of the yarns at a second surface of the web, and transporting the web along a processing station, at which station a binding layer is provided at the second surface of the web to fasten the yarns to the web, wherein the method further comprises transporting the sheet upstream of the processing station over a first bowed roller, wherein the transport distance between the bowed roller and the centre of the processing station is less than 2 meters.
