Polyester tufted carpet with polyester extrusion coating

A method for manufacturing a carpet, where the method comprises:

• providing polyester yarn comprising poly(ethylene terephthalate) (PET) at 800 denier to 2400 denier;
• providing a primary polyester backing comprising poly(ethylene terephthalate) spunbond nonwoven, at a basis weight of 80 g/m2 to 160 g/m2 at a thickness of 0.25 mm to 1.00 mm having first and second sides;
• tufting the polyester yarn into a first side of said primary polyester backing where said yarn extends from said second side of said primary backing;
• extruding polyester directly onto said second side of said primary backing and forming a polyester extrudate on said second side of said primary backing wherein said polyester extrudate provides a secondary backing layer that engages said polyester yarn extending from said second side of said primary backing wherein the secondary polyester backing layer locks the polyester yarn in the polyester primary backing, wherein said polyester extrudate comprises a blend of branched PET and a copolymer of PET (coPET) having a melting temperature in the range of 120° C. to 200° C. and wherein said coPET is selected from the group consisting of poly(cyclohexylenedimethylene terephthalateglycol), poly(cyclohexylenedimethylene terephthalate/isophthalate glycol) and poly(cyclohexylenedimethylene terephthalate).
