Abstract

A knitted fabric, such as present in a glove, provides cut resistance, wicking of moisture and thermo regulating properties. The fabric is made with at least one bundle of at least one yarn wherein the yarn comprises at least two strands: at least one of the strands in the bundle having a sheath/core construction with a sheath of cut resistant staple fibers and a metal fiber core; and at least one of the strands in the bundle having cut resistant aramid fibers and being free from metal fibers.

Claims (21)

1. A knitted fabric suitable to provide thermal resistance, moisture transport and cut resistance having two opposite faces with:

(a) a first face comprising (i) strands of a sheath/core construction with a sheath of cut-resistant fibers and a metal core and (ii) hydrophilic fibers and

(b) a second face comprising hydrophilic fibers with the proviso that the strands of the sheath/core construction are not present on the second face and the further proviso that hydrophylic fibers extend from the second face to the first face.

2. The knitted fabric of claim 1 wherein the cut resistant fibers comprise aramid.

3. The knitted fabric of claim 1 wherein the cut resistance fibers comprise polyethylene.

4. The knitted fabric of claim 1 wherein the cut resistance fibers comprise staple fibers.

5. The knitted fabric of claim 1 wherein the metal core comprises a ductile metal.

6. The knitted fabric of claim 5 wherein the metal is stainless steel.

7. The knitted fabric of claim 1 wherein the hydrophilic fibers comprise polyester.

8. The knitted fabric of claim 1 wherein the first face has a cut resistance of at least 4000 g measured in accordance with ASTM F1790-97.

9. The knitted fabric of claim 1 wherein the fabric has a thermal resistance of at least 0.50 clo.

10. The knitted fabric of claim 1 wherein the fabric has a permeability index of at least 0.50.

11. A knitted fabric suitable to provide thermal resistance, moisture transport and cut resistance having two opposite faces with:

(a) a first face comprising (i) strands of a sheath/core construction with a sheath of cut-resistant fibers and a metal core and (ii) hydrophilic fibers and

(b) a second face comprising hydrophilic fibers with the proviso that the strands of the sheath/core construction are not present on the second face and the further proviso that hydrophylic fibers extend from the second face to the first face,

wherein the fabric has a cut resistance on a first face of at least 4000 g measured in accordance with ASTM F1790-97, and a permeability index of at least 0.50.

12. The knitted fabric of claim 11 with a thermal resistance of at least 0.50.

13. The knitted fabric of claim 1 present as an article of clothing.

14. The knitted fabric of claim 13 present as a glove.

15. The knitted fabric of claim 11 present as an article of clothing.

16. The knitted fabric of claim 15 present as a glove.
