Process for the continuous uniform application of dye liquors to wet textile fabric webs

摘要

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 high-moisture 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.
