Abstract

There is provided a cut resistant yarn comprising a blend of first and second staple fibers, wherein, the first staple fibers are polymer-fibers, each first staple fiber comprising a polymer body encasing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most 25 microns; and the second staple fibers are different to the first staple fibers, wherein the weight ratio of the first to second staple polymer-fibers is from 1:99 to 99:1.

Claims (27)

1. A cut resistant yarn comprising a blend, wherein the blend consists of first and second staple fibers, wherein:

a) the first staple fibers are polymer-fibers, each first staple fiber comprising a polymer body encasing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most 25 microns; and

b) the second staple fibers are different than the first staple fibers, and wherein

the first to second staple fibers are present in the blend in a weight ratio from 1:99 to 99:1.

2. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 99:1 to 45:55.

3. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 46:54 to 1:99.

4. The yarn of claim 1 , wherein the first staple fibers are staple fibers of ultrahigh molecular weight polyethylene, staple fibers of polyamide, or staple fibers of polyester.

5. The yarn of claim 1 , wherein the second staple fibers are staple fibers of polyamide, polyester, acrylic, polypropylene, para-aramid, meta-aramid, wool, cotton, polyurethane, polyvinyl, polyalkylene, silk, wool, cellulose, linen, flax, hemp, ramie, or jute.

6. The yarn of claim 1 , wherein the first fibers are staple fibers of ultrahigh molecular weight polyethylene, and the second staple fibers are substantially free of ultrahigh molecular weight polyethylene.

7. The yarn of claim 1 , having a titer of between 100 and 10,000 dtex.

8. The yarn of claim 1 , wherein said the yarn is processable on a knitting machine of 7 or higher gauge.

9. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 10:90 to 35:65.

10. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 20:80 to 25:75.

11. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 47:53 to 95:5.

12. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 48:52 to 85:15.

13. The yarn of claim 1 , wherein the weight ratio of the first to second staple fibers is from 49:51 to 82:18.

14. A fabric comprising the yarn of claim 1 .

15. A method of making a cut resistant fabric comprising a step of knitting, braiding, or weaving a cut-resistant yarn to form the cut-resistant fabric, wherein the cut-resistant yarn consists of a blend of first and second staple fibers at a weight ratio of the first staple fibers to the second staple fibers from 1:99 to 99:1, wherein the first staple fibers are polymer-fibers, each first staple fiber comprising a polymer body encasing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most 25 microns, and wherein the second staple fibers are different than the first staple fibers.

16. A fabric obtained by the method of claim 15 .

17. The fabric according to claim 14 , having a cut resistance above 500 g and an areal density of at most 400 g/m2.

18. A cut-resistant product comprising the yarn of claim 1 .

19. The cut-resistant product of claim 18 , wherein the product is a garment.

20. The cut-resistant product of claim 19 , wherein the garment is a glove, an apron, a shirt, a vest, a jacket, trousers, a cuff or a sleeve.

21. A method of manufacturing a cut-resistant garment comprising a step of knitting a cut-resistant yarn to form the cut-resistant garment, wherein the cut-resistant yarn consists of a blend of first and second staple fibers at a weight ratio of the first staple fibers to the second staple fibers from 1:99 to 99:1, wherein the first staple fibers are polymer-fibers, each first staple fiber comprising a polymer body encasing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most 25 microns, and wherein the second staple fibers are different than the first staple fibers.

22. A method of manufacturing a garment comprising:

(i) providing a cut-resistant fabric which is comprised of a cut resistant yarn consisting of a blend of first and second staple fibers at a weight ratio of the first staple fibers to the second staple fibers from 1:99 to 99:1, wherein the first staple fibers are polymer-fibers, each first staple fiber comprising a polymer body encasing a hard component, said hard component being a plurality of hard fibers, said hard fibers having an average diameter of at most 25 microns, and wherein the second staple fibers are different than the first staple fibers; and

(ii) stitching the cut-resistant fabric into a garment.
