Claims

1. THE PROCESS FOR PREPARING A COMPACT INTERLACED MULTIFILAMENT TEXTILE YARN WHICH COMPRISES CONTINUOUSLY FEEDING A MULTIFILAMENT YARN BUNDLE UNDER TENSION THROUGH A PLURAL VORTEX TURBULENT ZONE FORMED BY A FLUID JET, JETTING THE FLUID WITH A FORCE WHICH SEPARATES THE YARN BUNDLE INTO MULTIPLE GROUPS OF ONE OR MORE FILAMENTS, CAUSING THE SEPARATED GROUPS TO OSCILLATE BETWEEN VORTICES AT SUCCESSIVE POSITIONS ALONG THE YARN TO INTERMINGLE THE FILAMENTS AS THE YARN PASSES THROUGH THE TURBULENT ZONE, AND WITHDRAWING THE FILAMENTS FROM THE TURBULENT ZONE UNDER A TENSION THAT FORMS A YARN BUNDLE ESSENTIALLY CONSISTING OF CLOSELY ADJACENT FILAMENTS FREE FROM RING-LIKE AND OTHER LOOPS, THE FILAMENTS BEING RANDOMLY INTERMINGLED WITH ADJACENT FILAMENTS AND GROUPS OF FILAMENTS ALONG THE YARN TO MAINTAIN THE UNITY OF THE YARN BY FRICTIONAL CONSTRAINT BETWEEN THE FILAMENTS.
