METHOD FOR IMPREGNATING A TEXTILE MATERIAL

摘要

The method is used for continuously impregnating textile materials in an impregnation compartment containing the impregnating liquor, the textile material being fed through said compartment, wherein the impregnating liquor contains a lye or a lye and additionally an oxidative bleaching agent as impregnating agent. Part of the impregnating liquor is branched off via a bypass (2, 2a), filtered and then fed to one or more sensors (17, 21) to determine the concentration of the impregnating agent. The branched-off part of the impregnating liquor is heated before it is filtered. Continuos, uninterrupted and a precise post-dosing of the impregnating agent is achieved.
