A tufted carpet and the method of preparing the same, which carpet comprises a backing sheet and a plurality of expanded cellular polymeric fibers secured to the backing sheet, the fibers providing a fibrous face surface, the fibers from the backing sheet secured thereto by the contact and compression of at least a part of the outer surfaces of the cellular polymeric fibers against the material of the backing sheet. The fibers may be expanded within the backing sheet or on either or both sides thereof. The method of preparing such a cellular tufted carpet comprises tufting gas-expandable fibers through a backing sheet, and, thereafter, heating the face, back, or both surfaces of the tufted backing sheet to a temperature sufficient to decompose the blowing agent in the gas-expandable fibers and to expand the fibers, thereby locking the fibers into the backing sheet.
