Means and method for extracting moisture from a traveling web of textile

Abstract

Means and method for extracting moisture from a traveling web of textile material containing high-moisture content processing fluid using a fluid applicator extending transversely across the path of the traveling web for applying low-moisture content fluid through holes in a distribution manifold on one side of the traveling web. A flow restricting roller is disposed on the opposite side of the travelling web in opposition to the fluid applicator holes closely downstream from the holes and serving to confine the low-moisture content fluid flow from the applicator into and through the traveling web, thereby causing displacement of high-moisture content fluid from the traveling web with low-moisture content fluid. The flow restricting roller is disposed at a spacing above the applicator less than the free-standing thickness of the traveling web and applies pressure to compress the traveling web and effect flow restriction. A plurality of such extracting means can be arranged in series for extraction and wet-on-wet finish applications. A surfactant can be included in the high moisture content processing fluid to produce foam that evidences expansion and resulting moisture extraction. Further, a surface active agent can be included to induce an explosive reaction that provides a scrubbing action to remove contaminants. Similarly chemical treating material can be used for displacing the high moisture containing fluid and thereby chemically impregnating the traveling web. Such chemical treating material may be a dyeing assisting agent.
