ABSTRACT:
A spring dye tube has a pair of end rings and at least one support ring intermediate these rings and concentric therewith. A plurality of spaced, rigid V-shaped ribs are integrally formed with the rings and define therewith an initially rigid network or 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 upon the application of a predetermined force thereon. A non-collapsible rigid, torque resistant section extends from each end ring to strengthen the structure. Straight parallel members add rigidity and extend from one end ring to the other.
