HIGH STRETCH YARN TEXTURING AND PACKAGE PRODUCTION ABSTRACT OF THE DISCLOSURE A method and apparatus for one step texturing and package preparation of high stretch continuous fila- ment yarn for ultimate package dyeing. Continuous fila- ment yarn is fed from a supply across a false twisting assembly, and a false twist is imparted thereto. The yarn is then passed over a roller and directed generally downwardly toward a take-up assembly including a dye spring. The yarn is overfed to the dye spring so that the yarn may relax completely and will have maximum skein shrinkage after dyeing. This is accomplished by passing the yarn through an air jet, resulting in an overfeed of up to 70-100%, which overfeed is not possible with con- ventional methods. The yarn package formed is soft, and may be package dyed according to conventional procedures.
