ABSTRACT:
A wall lining material consists of an upper mat body, a lower mat body and a granular moisture absorbent. The upper mat body and the lower mat body are made of a nonwoven fabric containing a multiplicity of fibers. The moisture absorbent is located between these two mat bodies. The mat bodies are sewn together over the laminated portion at many points by means of needle punching. This needle punching causes the fibers in the upper mat body to be connected with those in the lower mat wed and vice versa.
