ABSTRACT:
A non-wet processed tufted carpet (10) includes a plurality of face yarns (12), dyeable to the desired carpet color prior to tufting, which are tufted into and through a primary backing fabric (14) and which are more securedly held in place by a secondary backing fabric (16) without the use of an adhesive binder, the secondary backing fabric locking the face yarn in place upon the application of heat to a non-wet surface of the secondary backing fabric non-adjacent to the primary backing fabric. The tufted carpet (10) does not include any latex or binding adhesives which may cause odors or emit volatile organic chemicals. Moreover, the face yarn (12), primary backing fabric (14), and secondary backing fabric (16) are made of the same type of polymeric material, thereby creating a carpet which is wholly recyclable. The carpet (10) also uses only predyed fibers and yarns as the face yarn, thereby eliminating the need to dye or wet process and dry the carpet during its manufacture. The present invention also provides a non-wet processing method for the manufacture of tufted carpet.
