A modified secondary backing fabric (20) for carpet (50) comprises a secondary backing scrim fabric (15) and a fiber batt (21) integrated with the secondary backing fabric forming the modified fabric, providing a soft face (51) opposite the face (52) presented by the scrim fabric, uninterrupted by the scrim fabric. A carpet (50) comprises a face yarn (11); a primary backing fabric (12), the face yarn being tufted into the primary backing fabric; a modified secondary backing fabric (20) attached to the primary backing fabric; and an adhesive material (14) binding the face yarn to the primary backing fabric and the primary backing fabric to the secondary backing fabric. The modified secondary backing fabric (20) comprises a secondary backing scrim fabric (15) and a fiber batt (12) integrated as a unitary scrim, providing a soft face (51) forming the underside of the carpet, the soft face forming a barrier uninterrupted by the scrim fabric and blocking exudation of any of the adhesive material from the underside of the carpet. A method for the manufacture of a modified secondary carpet backing (20) comprises selecting a secondary backing scrim fabric (15) and a fiber batt (21); joining the two fabrics to form the modified secondary carpet backing (20), providing a soft face (51) opposite the face (52) presented by the scrim fabric, uninterrupted by the scrim fabric; and subjecting the modified fabric to heat sufficient to remove substantially all loose fibers (45) projecting from the soft surface. The present invention also provides a method for the manufacture of carpet.

1. A carpet comprising:a face yarn; a woven primary backing fabric, of closed weave construction said face yarn being tufted into said primary backing fabric; a modified secondary backing fabric attached to said woven primary backing fabric; an adhesive material binding said face yam to said woven primary backing fabric and said woven primary backing fabric to said modified secondary backing fabric; said modified secondary backing fabric comprising a first fabric of open weave construction having first and second faces, said first fabric comprising a leno weave of about 16 ends per inch warp direction by about 5 picks per inch weft direction; and a non-woven fiber batt having a weight ranging from about 0.5 to about 40 ounces per square yard and attached to and entangled with said first fabric, covering said first face and penetrating said second face sufficiently to integrate said first fabric and said fiber batt while maintaining said second face, thereby enhancing the structural integrity of said first fabric providing a soft surface forming the underside surface of said carpet and blocking exudation of any of said adhesive material from the underside of said carpet.
