Abstract
Abstract The present invention relates to a double cloth comprising a face cloth and a back cloth which are made of warp and weft threads and are held together by tied-in pile threads. To form a double plush cloth of high strength and stiffness it is provided that the warp and weft threads are each crossed by a warp thread float foundation weave, and additional cover weft threads essentially extended and floating on the outer surfaces of the face and/or back cloths are tied in by the warp threads, with adjacent cover weft threads being tied in by different warp threads of the particular face or back cloth.
