ABSTRACT:
A new and useful process of substituting one core for another in a wound package of textile yarn is provided. In preparation for subsequent liquid treatment of yarn wound on a substantially non-perforate rigid cylindrical core by substituting therefor a liquid-permeable longitudinally resilient cylindrical core of about the same or slightly smaller diameter, the package of yarn is first axially compressed. Then, the rigid core is pushed internally from the package while the resilient core substantially at the same time is pulled from a position external of the package to a position internal of the package to replace the rigid core with the resilient core. The application of the axial compression during core transfer prevents or minimizes rumpling of the yarns forming the outer portion of the package. The process is particularly suitable for preparing a package of false twist crimped polyester continuous multi-filament yarn for package dyeing.
