A carrier for textile yarn characterized by a construction designed to prevent undesirable sloughing-off or migration of the yarn during winding and unwinding and to reduce the amount of material needed to construct the carrier while retaining desired crush strength includes generally the following. An elongate hollow body having a transverse circular cross-section defines an outside surface of consecutive stepped portions extending around the body along the length of the carrier for defining a saw-toothed longitudinal configuration and yarn carrier areas which prevent undesirable sloughing-off or migration of the textile yarn during winding and unwinding. The inside surface of the body also includes somewhat similar consecutive stepped portions for cooperating with the outside surface to reduce the amount of material needed to construct the carrier while retaining a surface to fit the spindle of a textile machine. Opposing stepped portions of the outside and inside surfaces are positioned in a generally longitudinally staggered relationship for defining transverse portions in the body of the same radial thickness as would be present if the outside and inside surfaces were of a smooth unstepped configuration to provide reinforcement and crush strength to the carrier.

Textile yarn carrier

A generally cylindrical yarn carrier is illustrated suitable for improved compression dyeing wherein an undulating surface provides ridges and valleys for facilitating dye flow as well as nesting while providing increased strength and stability, avoiding skips and insuring uniform dyeing.
