Abstract
A fabric (10), for a wall covering or the like, is provided which has a needled non-woven batt (16) of staple fibers (12), to a front surface or one face (18) of which a cloth or film of woven, knitted fabric or extruded film (22) is attached, as by needle punching fibers (12) from the batt, or the like. Groups of staple fibers are punched from the batt through the cloth or film (22) to produce a distinctive pattern of clustered loops (34) of non-woven fibers having a visual background of cloth or film (22). The back surface (20) of the non-woven batt may optionally be backed (40) as by fusing, latexing, or the like. A novel method of making a fabric is provided and comprises needling (15) the non-woven batt, attaching the cloth or film (22) to the batt, needling clustered loops (34,35) from the non-woven fibers of the batt through the cloth or film (22) to define a pattern of loops with the cloth or film ( 22) visible between the clustered loops, and optionally backing the non-woven batt. The fabric (10) has sound and heat insulating characteristics.
