ABSTRACT:
Knitware in hose form is prepared for a wet treatment, a preliminary dewatering, and for drying, by winding the hose into wound laps under a constant winding tension, so that the laps have a density of more than 200 and less than 400 g/dm.sup.3. The lap is coaxially compressed to reduce its original axial length by 3% to 8% and in this state the lap is exposed to dye liquor, flowing, for example, alternately radially inwardly or radially outwardly or axially in alternate directions. The lap is then preliminarily dewatered in an unvaried state, preferably by rotation. Thereafter, the lap is subjected in the same state to a drying treatment. The drying treatment may, in the alternative, be performed after the knitware has been unrolled and the hose has been cut lengthwise for securing the knitware in its spread-out state to a tentering frame which is then passed through a drying chamber.
