ABSTRACT:
In a method for wet-finishing textile goods in the extraction process, the textile goods are made-up in the form of spools or in packages. They are placed in this made-up form in a vessel closable in a pressure-tight manner and the air is then at least substantially removed from the interstices in the textile goods. In the course of the method, the liquor present in the form of an aerosol is made to flow through the textile goods. In order to reduce the water and energy consumption and to also improve the quality of the treatment, the textile goods are first transferred to a state with increased temperature and low residual moisture. Subsequently or or simultaneously, the air is at least substantially removed from the interstices in the textile goods, and after this state has been attained, a gaseous medium under increased pressure which together with the liquor forms an aerosol is made to flow directly through the textile goods.
