Abstract

A cut, slash and/or abrasion resistant shaped knit garment having both high cut resistance and preferably light fabric weight, a cut resistance of at least 1500 (as measured by ASTM-F1790-2005) and preferably a fabric weight of no more than 27.9 ounces/square yard (OPSY).

Claims

1. A shaped knit garment, consisting essentially of:

one or more fabric panels prepared from yarn consisting of 100% cut, slash and/or abrasion resistant yarn and prepared by shaped knitting,

wherein the shaped knit garment has a cut resistance of from 1500 to 6200 (as measured by ASTM-F1790-2005) and a fabric weight of no more than 27.9 ounces per square yard (OPSY),

wherein the one or more fabric panels are made by a shaped knitting process by which one or more fabric panels are formed directly during the shape knitting process into the final shape of the garment or shapes needed for assembly into the final shape of the garment, and form an entirety of the garment body and arms,

wherein the shaped knit garment is seamless as directly formed or formed by joining the fabric panels using cut, slash and/or abrasion resistant yarn,

wherein the garment has cuffs at an end of each arm, wherein each cuff has a loop affixed to, and located in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position,

wherein the garment is a jacket or a sweater, and

wherein the garment contains no metal grommets.

2. The shaped knit garment of claim 1, wherein the cut resistance of the yarn in the area of the cuffs is from 2500 to 6200.

3. The shaped knit garment of claim 2, wherein the body of the garment has a cut resistance of 2173.9 to 6200 and cuff has a cut resistance of 2761.6 to 6200.

4. The shaped knit garment of claim 1, wherein the fabric weight is from 8 to 20 OPSY.

5. The shaped knit garment of claim 1, wherein the cut, slash and/or abrasion resistant yarn is a high performance yarn.

6. The shaped knit garment of claim 1, wherein the cut, slash and/or abrasion resistant yarn is a composite yarn.

7. The shaped knit garment of claim 1, wherein all yarns used in construction of the garment are cut resistant yarns.

8. The shaped knit garment of claim 1, wherein the garment is a jacket having a plastic zipper from neck to waist in front or back that is hidden from view when the jacket is worn.

9. The shaped knit garment of claim 1, wherein the garment is a sweater.

10. A shaped knit garment according to claim 1, consisting essentially of:

one fabric panel prepared from yarn consisting of 100% cut, slash and/or abrasion resistant yarn and prepared by shaped knitting,

wherein the shaped knit garment has a cut resistance of from 1500 to 6200 (as measured by ASTM-F1790-2005) and a fabric weight of no more than 27.9 ounces per square yard (OPSY),

wherein the one fabric panel is made by a shaped knitting process by which the fabric panel is formed directly during the shape knitting process into the final shape of the garment, and forms an entirety of the garment body and arms,

wherein the shaped knit garment is seamless as directly formed,

wherein the garment has cuffs at an end of each arm, wherein each cuff has a loop affixed to, and located in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position,

wherein the garment is a jacket or a sweater, and

wherein the garment contains no metal grommets.

11. A shaped knit garment according to claim 1, consisting essentially of:

fabric panels prepared from yarn consisting of 100% cut, slash and/or abrasion resistant yarn and prepared by shaped knitting,

wherein the shaped knit garment has a cut resistance of from 1500 to 6200 (as measured by ASTM-F1790-2005) and a fabric weight of no more than 27.9 ounces per square yard (OPSY),

wherein the fabric panels are made by a shaped knitting process by which fabric panels are formed directly during the shape knitting process into shapes needed for assembly into the final shape of the garment, and form an entirety of the garment body and arms,

wherein the shaped knit garment is formed by joining the fabric panels using cut, slash and/or abrasion resistant yarn,

wherein the garment has cuffs at an end of each arm, wherein each cuff has a loop affixed to, and located in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position,

wherein the garment is a jacket or a sweater, and

wherein the garment contains no metal grommets.

12. The shaped knit garment of claim 11, wherein the cut resistance of the yarn in the area of the cuffs is greater than the cut resistance of the yarn forming the body of the shape knit garment.

13. The shaped knit garment of claim 10, wherein the loop is affixed to, and located entirely in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position.

14. The shaped knit garment of claim 11, wherein the loop is affixed to, and located entirely in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position.

15. The shaped knit garment of claim 10, wherein the loop is elastic and affixed to, and located entirely in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position.

16. The shaped knit garment of claim 11, wherein the loop is elastic and affixed to, and located entirely in, the inside of the cuff through which loop a wearer'"'"'s thumb is placed to hold the cuff in position.
