A carpet is constructed of a face yarn comprised principally of a bulked continuous filament carpet face yarn or a bulk staple carpet face yarn wherein the face yarn comprises principally a bundle of drawn and crimped bi-component filaments, and wherein each such filament consists essentially of an outer lengthwise sheath of a dyeable polymeric material surrounding a core of a different polymeric material, and wherein the two polymeric materials are not dyeable by the same method. A particularly advantageous filament structure comprises a nylon sheath surrounding a polyester core. The nylon sheath may be dyed or pigmented. For automotive and similar usage, a polyester sheath surrounding a core of, for example, polyethylene, may be preferred.
