Abstract
Process for creating uniform flow conditions for circulating liquors flowing through textile wound packages or packaged material of synthetic and/or natural fibers in the course of machine dyeing by the exhaustion method under elevated pressure, wherein the zones of liquor flow which deviate from a mean value are determined across the entire block of material by measuring the differential pressures within the wound packages of material at several pairs of positions, whereupon the localized flow differences are equalized in all positions of the block of material by altering the properties and structures of the packages of material, by modifying the dyeing program, by varying the pumping power, by design changes in the dyeing machine and/or special selection and optimum metering of auxiliaries.
