<p>Provided is tufted (11) carpet (10) with a two-part primary backing (12) and without application of a secondary backing. The upper, or face, backing (14) is a conventional woven or non-woven polypropylene, and the lower, or back, backing (15) is a stronger, less stretchable than the first backing, open weave fabric. First backing (14) and second backing (15) are contiguous with each other, with the first backing forming a first side of primary backing (12) and second backing (15) forming an opposite side of the primary backing. The tufts of yarn (11) are sewn through both parts of primary backing (12), which holds the parts (14, 15) together, and causes some of the back stitches to protrude for better coating with adhesive and forms a plurality of back stitches on the opposite side of primary backing (12) wherein at least a major portion of the back stitches secure first backing (14) to second backing (15). The resulting carpet may be fully back coated, and may have a secondary backing adhered thereto. The lower backing prevents elongation, stretching and shrinking of the carpet during manufacture and subsequent processing.</p> |
