Abstract
The invention provides yarn carriers for package dyeing of yarns which include an improved transfer tail engaging and segregating surface on the exterior of an axially projecting nesting collar. The transfer tail engaging and segregating surface is formed by a plurality of axial protrusions which are arranged to form a circumferentially interrupted surface on the axially projecting nesting collar. As a result of the protrusions, transfer tail windings are forced to be formed in an overlapping criss-cross manner which provides for improved access by dye liquor to the transfer tail windings. In addition, the radial protrusions can be provided of a height to form a positive engagement with the inside surface of a female nesting collar of an adjacent yarn carrier.
