Abstract
An absorbent facing material comprising 10 to 30% cellulosic, staple length, textile fibers, 60 to 80% of fluff wood pulp, and 5 to 25% of a resin binder material. The cellulosic fibers are substantially only on one surface of the material and the wood pulp substantially only on the opposite surface. The binder is distributed in a predetermined pattern with the surface containing the cellulosic fibers having a higher concentration of binder than the surface containing the wood pulp fibers.
