ABSTRACT:
A woven or spiral papermaker's or industrial fabric characterized in that at least a portion of its fibers have two or more thin fins, some of which fins are designed for ease of flexing or compression by incorporation of a reduced cross section "hinge" area or by a variation in thickness of more than 20 per cent as a function of distance from the fiber center. This will achieve interlocking between crossing fibers at significantly reduced "beat-up" force in weaving or less shrinkage force in spiral fabrics. By remaining extended where there is no fiber to fiber crushing action, the fins fill the fabric interstitial spaces and control fabric porosity. Significant cost and quality benefits are achieved.
