ABSTRACT:
A method for the heat treatment of textiles, particularly advantageous for textiles wound on cops or bobbins, comprises applying a vacuum to a steamer chamber in which the textiles have been placed. When a sufficient vacuum has been reached a treatment liquid is introduced and the vacuum source shut off maintains the vacuums. The treatment liquid is then heated to generate a saturated steam treatment for the textiles. The liquid and steam are then pumped out of the chamber and a vacuum re-instituted for evacuation, cooling and drying, after which the chamber is returned to ambient. Subsequent cycles may be performed with other liquid treatments. An apparatus for carrying out the method may be in the form of a closed system in which the vessels from which the liquid treatment are drawn are coupled to the treatment chamber to allow return of the liquids when the liquids are pumped out. Liquid loss is thus minimized and efficiency increased.
