A COMPOSITE YARN COMPRISING A WRAPPED YARN FORMED FROM AT LEAST ONE WRAPPING STRAND AND AT LEAST ONE CORE STRAND, SAID WRAPPING STRAND BEING ASSOCIATED WITH SAID CORE STRAND IN THE FORM OF DOUBLED-BACK LOOPS WOUND AROUND SAID CORE STRAND FOR A MULTIPLICITY OF TURNS, TOGETHER WITH A FALSELY-PLIED STRAND SECURED TO SAID WRAPPED YRAN AT PERIODIC INTERVALS BY A SECONDARY WRAPPING, SAID SECONDARY WRAPPING COMPRISING LOOPS DERIVED FROM THE WRAPPING STRAND OF THE WRAPPED YARN BEING DISPOSED AROUND SAID FALSELY-PLIED STRAND AND AROUND SAID WRAPPED STRAND, SAID WRAPPED STRAND AND SAID FALSELY-PLIED STRAND POSSESSING NO NET TRUE TWIST AROUND ONE ANOTHER.

Claim 3

Claim 4

THE METHOD OF PRODUCING A FALSELY-PLIED YARN WHICH COMPRISES PASSING AT LEAST ONE WRAPPING STRAND AND AT LEAST ONE CORE STRAND THROUGH A GENERALLY CYLINDRICAL BODY OF FLUID WHIRLING ABOUT A CENTRAL AXIS, THE WRAPPING STRAND BEING FED AT A RATE FASTER THAN THE CORE STRAND, DISPOSING THE WRAPPING STRAND AROUND THE CORE STRAND IN THE FORM OF DOUBLED-BACK LOOPS WOUND FOR A MULTIPLICITY OF TURNS AROUND SAID CORE STRAND, A PORTION OF SAID LOOPS AT INTERVALS EXTENDING RADIALLY OUTWARD FROM THE AXIS OF SAID CORE STRAND; BRINGING THE THUS-FORMED WRAPPED YARN INTO JUSTAPOSITION WITH A SECOND STRAND, PASSING THE COMBINED YARN AND SECOND STRAND THROUGH A GENERALLY CYLINDRICAL BODY OF FLUID WHIRLING ABOUT A CENTRAL AXIS, WRAPPING AT LEAST SOME OF THE RADIALLY-DISPOSED LOOPS OF THE WRAPPED YARN AROUND BOTH THE SECOND STRAND AND AROUND THE WRAPPED YARN, AND REMOVING THE THUS-FORMED FALSELY-PLIED FROM THE WHIRLING BODY OF FLUID.
