Abstract
A composite yarn and a method for forming the composite yarn include the composite yarn being formed from different components wherein the resultant yarn exhibits characteristics not apparent from the individual component yarns with the composite yarn being formed from a first component yarn strand and a second component yarn strand with the first and second component strands being comingled using an entanglement device with the co-mingling occurring with the first and second component strands subject to a first tension value which is subsequently increased to a second, higher tension value for winding. A method for forming such a composite yarn includes propelling the strands through the entanglement device at a first tension value, entangling the strands, imparting a second tension value to the resultant entangled strands and winding the entangled strands.
