Abstract
A yarn carrier is described and claimed herein suitable for use for winding textile yarn thereon and dyeing same at full length or while the carrier is in a 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 an initially rigid intermediate structure that has an open network to permit passage of dye therethrough and that is capable of axial compression with respect to the length of the tube upon receipt of a predetermined amount of force. Axially extending rigid members are provided throughout the intermediate tube structure to provide the initially rigid tube with at least certain of the axial rigid members being deformable when subjected to sufficient axial force with respect to the tube to deflect or rupture and thus permit axial collapse of the tube. The internal structure of the tube may include rings, helical leads or the like and may further include additional axially extending rigid members that are not deformable by the predetermined axial force on the tube.
