ABSTRACT:
Described is a process for the processing of organic textile materials by application of an aqueous dispersion or solution of a processing agent having affinity for the fibres, with a ratio of goods to liquor of at most 1:2, and subsequent fixing of the processing agent by means of a steam treatment, characterized in that the ratio of goods to liquor of the applied liquor is increased, below the absorption temperature of the processing agent, by the admission of saturated steam in such a manner that the processing agent is uniformly dispersed on the material before commencement of the fixing process.
The advantages of this process are that there are used practically no products contaminating the waste liquors, particularly no surface-active substances tending to form foam, and that there are nevertheless obtained perfectly satisfactory processing effects. Surprisingly, moreover, irregularities caused by the material are levelled out during dyeing.
