ABSTRACT:
This invention provides for a process for the wet treatment of textiles in which in a pressure-tight high-temperature resistant container the liquor always flows outwardly laterally at an angle from vertical through the inside of the textile material, flows down on the outside of the textile material to a sump situated beneath the latter and is pumped back from the sump into the interior of the textile material. Thus the material during the process is not immersed in the liquor and the influence of the high pressures and temperatures conventionally applied upon the textiles in their wet treatment is avoided and a lower liquid to textile ratio is employed.
The invention also provides an apparatus for carrying out the wet treatment of textiles, comprising a closed container, an insert member located within said container, means for supporting the textile material provided on the insert member, a liquor circulation system, a pump which communicates with the container, a heating and a cooling system, steam and coolant supply means, condensate and coolant outlets and means for measuring and controlling the level of liquid in the container.
