MODIFIED SECONDARY BACKING FABRIC, METHOD FOR THE MANUFACTURE THEREOF AND CARPET CONTAINING SAME

摘要

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 primar y 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 an d 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 sof t surface. The present invention also provides a method for the manufacture of carpet.
