This heading covers carpets and textile floor coverings, other than those covered by a more specific heading of this Chapter. The heading includes :(1) Bonded pile carpets, where the pile use surface is bonded either to a substrate or directly to an adhesive which forms the substrate. The bonding may be achieved by adhesion or heat or a combination of both or by ultrasonic welding. The pile can be bonded either to a single backing surface or between two backing surfaces, in the latter case for separation into two carpets. (2) Nonwoven carpets, consisting of a layer of carded textile fibres crimped between grooved rollers to form loops, which may either be held in position by a thick coating of rubber, plastics, etc., which also serves as a backing, or be bonded to a backing fabric by similar adhesives. (3) Carpets made by flocking , i.e., by implanting textile fibres upright in a textile backing, coated with rubber, plastics, etc. (4) Knitted carpets and carpeting. These generally have the appearance of moquette or, sometimes, of furskins.
