Patent ID: RE42265

Claim:
A cut resistant, stretchable yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising a stretchable second yarn and a bundle of continuous filaments formed of a synthetic material, said stretchable second yarn being of substantially smaller denier than the bundle of filaments and being initially under tension to cause it to stretch , each of said continuous filaments of the bundle of continuous filaments having a longitudinal axis and , said bundle being in a twisted with respect to one another whereby condition wherein the bundle of filaments have has a torque in a first rotational direction applied to them , said bundle of continuous filaments being helically wound about the stretched stretchable second yarn to apply wherein said bundle of filaments has a torque in a second rotational direction to said filaments to cause them to untwist with respect to one another establishing a force in said second rotational direction, said torque in said second rotational direction substantially cancelling said torque in said first rotational direction, whereupon said bundle of filaments again assumes the a condition wherein all of said filaments of said bundle have a substantially zero torque and are substantially parallel to one another and to the longitudinal axis of the yam yarn and the stretchable yam second yarn twists about its the longitudinal axis of the yarn and moves to a position wherein it is helically disposed around the parallel bundle of filaments of said bundle .
