Abstract: A sod comprising a root support matrix that itself comprises a mixture of soil and/or sand, and shredded carpet fragments, wherein the shredded carpet fragments are from about one-tenth percent (0.1%) to about five percent (5.0%) by weight of the matrix; and a plurality of plants growing in said root support matrix, said plants having roots entangled with said shredded carpet fragments. The shredded carpet fragments comprise a mass of entangled face yarns some of which yarns have bits of carpet backing material attached thereto, wherein at least about ninety percent (90%), and more preferably at least about ninety-five percent (95%), of the bits of carpet backing material have no one dimension greater than about one-quarter (0.25) inch.

Abstract: A sod comprising a root support matrix that itself comprises a mixture of soil and/or sand and shredded carpet pieces has a beneficial plant adjuvant disposed on the shredded fabric pieces, preferably in the form of shredded carpet pieces. The beneficial plant adjuvant is initially suspended in an aqueous solution of water and a degradable, slow-release, water-soluble liquid polymer that when dried forms a coating on the surface of the shredded carpet pieces.

Abstract: A fabric, useful as a primary carpet backing, woven in both the warp and weft directions from filmy elements in the form of longitudinally-oriented, splittable ribbons formed from a blend of a major amount of polyester and a minor amount of a polyolefin. The ribbons split longitudinally when punctured by a tufting needle, thus providing for a more secure grip on the tufted carpet yarn than that given by conventional polyester backings. The use of polyester as a principal component overcomes certain drawbacks of polypropylene backings. Alternative processes for making these fabrics, each involving a heat-treating step at a temperature of at least 150.degree. F. (66.degree. C.) for a sufficient period of time to render the ribbons splittable, are also disclosed.

Abstract: A stitch-bonded fabric having two split-film layers as a weft component and one split-film layer as a warp component held together by a stitching yarn is improved significantly in its performance as a primary backing for a tufted pile carpet by having a nonwoven sheet of continuous organic filaments attached to the warp component. In tufting, the nonwoven sheet becomes the back side of the backing.
