ABSTRACT:
A dye tube has a pair of end rings and at least one support ring intermediate these rings and concentric therewith. A plurality of alternate, rigid V-shaped and inverted V-shaped ribs are integrally formed with the rings and defined therewith an initially rigid network of winding yarn to be dyed through which dye can flow. The ribs are arranged in separate spaced groups so as to tend to collapse axially in opposite directions upon the application of a predetermined force thereon. A non-collapsible torque resistant section extends from each end ring to strengthen the structure and prevent it from buckling.
