Abstract: A tufted carpet is made by tufting yarn through a primary backing of at least two layers, including a first backing layer and a second backing layer. The first backing layer is formed of a woven material, a non-woven material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer is formed of a woven material of ribbons of polypropylene, polyethylene or combinations of polypropylene and polyethylene, a woven fiber glass material, a leno weave material, an open weave material, a plastic net or a plastic sheet material. A plurality of tufts of yarn that are sewn through the primary backing are exposed on one side of the primary backing for forming face yarns, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure each layer of the primary backing to each other layer.
