Abstract
An absorbent facing is disclosed which has significant one-way valve characteristics for aqueous fluids. The facing is produced by a process which comprises the steps of: (a) superimposing a thin polymer film and a first web comprising absorbent fibers, to form a second web; (b) heating the second web to a temperature such that the polymer film is in a formable state; (c) while the said second web is so heated, simultaneously applying shearing and compressive forces to the second web to form said polymer film into a coating on said first web, the coating comprising a fine pattern of continuous areas which lie between and interconnect discontinuous areas, wherein the polymer in the continuous areas comprises a continuous or substantially continuous coating on the surface of said first web, and wherein most of the polymer in the discontinuous areas is coated on individual fibers; and (d) cooling the coated web thus formed to cool the polymer below its forming temperature.
