METHOD OF AND APPARATUS FOR DYEING OR OTHERWISE TREATING AN ELONGATE FABRIC MATERIAL

摘要

A method of dyeing or otherwise treating an elongate fabric material including slide fastener stringers comprises winding said fabric material on a rotatable frame means disposed in a dye chamber and reducing the diameter of said frame means to an extent necessary to compensate for the amount of shrinkage developed in said fabric material during the dyeing operation. A dyeing apparatus for dyeing or otherwise treating an elongate fabric material comprises a cylindrical vessel and a beam mounted concentrically therein and removable therefrom, the beam having a plurality of chambers isolated one from another and a dye frame unit rotatably mounted on a driven shaft extending axially through the beam, a first motor rotating the driven shaft and a second motor operatively associated with means for moving the driven shaft axially toward and away from the first motor, and means radially movable toward and away from the driven shaft to adjust the overall diameter of the dye frame unit on which the fabric material is wound.
