A collapsible dye spring or the like described and claimed herein suitable for use for winding textile yarn thereon and dyeing same while the spring is in a partially collapsed condition. In the collapsed condition, adequate and uniform dye flow from the inside of the tube outwardly is permitted to evenly dye the yarn wound thereon. A tube having terminal flanges or rings is provided with at least one continuous helical lead of a predetermined pitch extending between and joining the flanges. The helical lead is flexible and is provided with means along its length to rigidify the tube and limit the axial compression of same. In the preferred form of the spring, a plurality of helical leads of predetermined pitches extend continuously from the first ring to the second ring with a plurality of generally perpendicularly disposed members connecting the leads along the length of the helices, the perpendicular disposition being with respect to the rings and not the leads. Also the members connecting the leads may have additional material surrounding same that tapers quickly into the lead outwardly from the perpendicular member.
