Abstract
A tufted carpet is made by tufting yarn through a primary backing including a first backing layer and a second backing layer. The first backing layer is formed of a woven, non-woven or plastic sheet material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer comprises a leno weave, open weave, plastic net or plastic sheet material. The first backing layer and the second backing layer are arranged so that the first backing layer forms a first side of the primary backing and the second backing layer forms an opposite side of the primary backing. The tufts of yarn that are sewn through the primary backing are exposed on the first side of the primary backing for forming face yams, 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 the first backing layer to the second backing layer.
