    • 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.
    • 非湿润加工的簇绒地毯(10)包括多个面纱(12),其在簇绒之前可染色成期望的地毯颜色,其被簇绒入并穿过主衬里(14),并且更牢固地保持在 在不使用粘合剂粘合剂的情况下通过辅助背衬织物(16)放置,辅助衬里织物将面纱线施加到第二背衬织物的非湿润表面上而不与主背衬相邻 布。 簇绒地毯(10)不包括可能引起气味或发出挥发性有机化学物质的任何胶乳或粘合粘合剂。 此外,面纱(12),主衬布(14)和辅助衬布(16)由相同类型的聚合材料制成,从而形成完全可回收的地毯。 地毯(10)也仅使用预制纤维和纱线作为面纱,从而消除了在制造过程中染色或湿法处理和干燥地毯的需要。 本发明还提供了一种用于制造簇绒地毯的非湿法加工方法。
