Abstract: An improved collapsible yarn dye tube assembly is disclosed comprising two tubular members, one of which telescopes an initial limited distance into the other. Both tubular members have an outer end and an inner end with the telescoping arrangement taking place at the inner ends thereof. A plurality of openings or perforations around the tubular members and extending at least a major portion of the length thereof permit dye liquor to pass therethrough when yarn is wound around the dye tube and the package is placed in a dye kettle. The outer ends of the tubular members possess thickened wall portions so as to permit an abutting relationship between adjacent dye tubes whereby a solid relationship is established and whereby pressure transmitted from one dye tube to the next for collapsing thereof is evenly transmitted along the tube. Dye spindle alignment means are also provided on the inner periphery of the members to center the yarn package around the dye spindle. Alignment means may also be provided at the inner ends of the tubular members to prevent blockage of the perforations upon collapse of the dye tube. Further, the dimensions of the assembled dye tube establish driving contact between the tube and a winder drum at least at both outer ends and the middle of the assembly to improve winding the package produced.
