Abstract
Cut resistant yarns suitable for knitting gloves and sleeves and methods of making the yarns are disclosed. The yarns are made up of a bundle of continuous filaments formed of a synthetic material, e.g., polyethylene, polypropylene, nylon or polyolefin, and a stretchable yarn, e.g., Spandex® or Lycra®. The yarns are made in such a manner that when completed the continuous filaments are substantially parallel to one another and to the longitudinal axis of the yarn so that items made from them will not twist or curl up, yet will provide good resistance to cutting.

A cut resistant, stretchable yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising a bundle of continuous filaments formed of a synthetic material and a stretchable yarn, each of said continuous filaments of said bundle of continuous filaments having a longitudinal axis, said stretchable yarn being wound under tension about said bundle of continuous filaments in a helical pattern in a first rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle in said first rotational direction, said bundle of continuous filaments being twisted in a second and opposite rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle in said second rotational direction, said torque in said first direction substantially cancelling said torque in said second direction, whereupon after said stretchable yarn has been made said longitudinal axes of said continuous filaments are substantially parallel to one another and to said longitudinal axis of said yarn.
A method for making a cut resistant yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising:
- (A) providing a bundle of continuous filaments formed of a synthetic material and a stretchable yarn, each of said continuous filaments of said bundle of continuous filaments having a longitudinal axis
- (B) winding said stretchable yarn under tension about said bundle of continuous filaments in a helical pattern in a first rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle in said first rotational direction;
- (C) twisting said bundle of continuous filaments in a second and opposite rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle in said second rotational direction, said first and second torques essentially cancelling each other;
- and
- (D) releasing said yarn, whereupon said longitudinal axes of said continuous filaments are substantially parallel to one another and to said longitudinal axis of said yarn.
A cut resistant, stretchable yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising a stretchable yarn and a bundle of continuous filaments formed of a synthetic material, said stretchable 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 being oriented initially parallel to one another, said bundle of continuous filaments being helically wound about the stretched stretchable yarn to apply a torque in a first rotational direction to said filaments to cause them to twist with respect to one another in said first rotational direction, said bundle of continuous filaments and said stretchable yarn being thereafter twisted in a second and opposite rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle and to said stretchable yarn in said second rotational direction, said torque in said second direction substantially cancelling said torque in said first direction, whereupon said bundle of filaments again assumes the condition wherein all of said filaments of said bundle are parallel to one another and to the longitudinal axis of the yarn and the stretchable yarn twists about its longitudinal axis and moves to a position wherein it is helically disposed around the parallel filaments of said bundle.
A method for making a cut resistant yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising:
- (A) providing a stretchable yarn and a bundle of continuous filaments formed of a synthetic material, each of said continuous filaments of said bundle of continuous filaments having a longitudinal axis and being oriented initially parallel to one another, said stretchable yarn being of substantially smaller denier than the bundle of filaments;
- (B) tensioning the stretchable yarn to cause it to stretch;
- (C) winding said bundle of continuous filaments helically about the stretched stretchable yarn to apply a torque in a first rotational direction to said filaments to cause them to twist with respect to one another in said first rotational direction, and
- (D) twisting said bundle of continuous filaments and said stretchable yarn in a second and opposite rotational direction with respect to said longitudinal axis of said yarn to apply a torque to said bundle and to said stretchable yarn in said second rotational direction, said torque in said second direction substantially cancelling said torque in said first direction, and
- (E) releasing said bundle of filaments and said stretchable yarn, whereupon said bundle of filaments again assumes the condition wherein all of said filaments of said bundle are parallel to one another and to the longitudinal axis of the yarn and the stretchable yarn twists about its longitudinal axis and moves to a position wherein it is helically disposed around the parallel filaments of said bundle.
A cut resistant, stretchable yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising a stretchable yarn and a bundle of continuous filaments formed of a synthetic material, said stretchable 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 being twisted with respect to one another whereby the filaments have a torque in a first rotational direction applied to them, said bundle of continuous filaments being helically wound about the stretched stretchable yarn to apply a torque in a second rotational direction to said filaments to cause them to untwist with respect to one another in said second rotational direction, said torque in said second direction substantially cancelling said torque in said first direction, whereupon said bundle of filaments again assumes the condition wherein all of said filaments of said bundle are parallel to one another and to the longitudinal axis of the yarn and the stretchable yarn twists about its longitudinal axis and moves to a position wherein it is helically disposed around the parallel filaments of said bundle.
A method for making a cut resistant yarn suitable for knitting gloves and sleeves, said yarn having a longitudinal axis and comprising:
- (A) providing a stretchable yarn and a bundle of continuous filaments formed of a synthetic material, each of said continuous filaments of said bundle of continuous filaments having a longitudinal axis;
- (B) twisting said filaments with respect to one another whereby the filaments have a torque in a first rotational direction applied to them;
- (C) tensioning the stretchable yarn to cause it to stretch;
- (D) winding said bundle of continuous filaments about the stretched stretchable yarn to apply a torque in a second rotational direction to said filaments to cause them to untwist with respect to one another in said second rotational direction, said torque in said second direction substantially cancelling said torque in said first direction;
- and releasing said bundle of filaments and said stretchable yarn, whereupon said bundle of filaments again assumes the condition wherein all of said filaments of said bundle are parallel to one another and to the longitudinal axis of the yarn and the stretchable yarn twists about its longitudinal axis and moves to a position wherein it is helically disposed around the parallel filaments of said bundle.
