Abstract: of the disclosure In order to maintain at a constant value the quantity of liquor applied in the wet-on-wet application of two liquors of differing composition it is necessary that the fabric web which is wet from the preceding wet treatment is first uniformly partially dewatered and the second liquor is then applied uniformly. By using highmoisture measuring instruments after the dewatering and also controlling the same with the aid of measured values, and by proceeding similarly after the repeated application of liquor, it is possible to stay within the tolerances which are necessary to ensure the uniformity of the two processes. The new processing technique makes it possible to dispense with the customary intermediate drying after the pretreatment and, in contrast with the custom hitherto, to apply dye liquors directly onto the wet fabric webs. The danger of a dilution of liquor during the processing on the padding mangle is avoided by this special method.

Abstract: Process and apparatus for applying in a continuous and level manner aqueous impregnating liquors to water-wet textile goods to prevent unlevelness of the liquor applied to the goods. This is accomplished by partly or completely exchanging the moisture on the goods by sucking or pressing liquor through the goods and by circulating the liquor to be applied while maintaining its volume and concentration at a constant value. The new technique makes it possible to dispense with the customary intermediate drying stage after the pretreatment.
