With the Power-Tex open-width washing machine a world novelty has been developed. Used for washing out dyed and printed fabrics, the machine achieves fastness rsults that used to be thought unattainable at production speeds in excess of 10 m/min. In the pretreatment field the intensive washing and treatment compartment is used for desizing, boiling and demineralisation processes. The Power-Tex is used as a unit before Convi-Tex or Econ-Tex washing machines or for upgrading third-party ranges. It is also eminently suitable as an open-width washing machine before rope ranges.
