Abstract

Apparatuses and associated methods of manufacturing are described that provide for cut-resistant yarn structures. An example cut-resistant yarn structure includes a first cut-resistant core filament a second cut-resistant core filament. The yarn structure further includes a first covering yarn that is wound over the first cut-resistant core filament and the second cut-resistant core filament. The first covering yarn includes a core-spun yarn in which staple fibers are spun over a third cut-resistant core filament. The yarn structure also includes one or more covering layers wound over the first covering yarn that may serve as the exterior layer for the cut-resistant yarn structure. In some instances, the first and second cut-resistant core filaments include a core-spun yarn in which staple fibers are spun over the first cut-resistant core filament and/or the second cut-resistant core filament.

First claim

The invention claimed is:

1. A cut-resistant yarn structure comprising:
a first cut-resistant core filament;
a second cut-resistant core filament;
a first covering yarn wound over the first cut-resistant core filament and the second cut-resistant core filament, wherein the first covering yarn comprises a core-spun yarn in which staple fibers are spun over a third cut-resistant core filament; and
a second covering yarn, along with the first covering yarn, wound over the first cut-resistant core filament and the second cut-resistant core filament, wherein the second covering yarn comprises a core-spun yarn in which staple fibers are spun over a fourth cut-resistant core filament.

2. The cut-resistant yarn structure according to claim 1 , wherein the first cut-resistant core filament comprises one of basalt, steel, or steel alloy.

3. The cut-resistant yarn structure according to claim 1 , wherein the second cut-resistant core filament comprises one of basalt, steel, or steel alloy.

4. The cut-resistant yarn structure according to claim 1 , wherein the third cut-resistant core filament comprises one of basalt, steel, or steel alloy.

5. The cut-resistant yarn structure according to claim 1 , wherein the staple fibers of the core-spun yarn of the first covering yarn comprise polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, moisture management material, or a blended combination thereof.

6. The cut-resistant yarn structure according to claim 1 , wherein the staple fibers of the core-spun yarn of the first covering yarn comprise fire retardant regenerated cellulose, polyimide, para-aramid, polyacrylonifrile (PAN), or a blended combination thereof.

7. The cut-resistant yarn structure according to claim 1 , wherein the first cut-resistant core filament comprises a core-spun yarn in which staple fibers are spun over the first cut-resistant core filament.

8. The cut-resistant yarn structure according to claim 1 , wherein the second cut-resistant core filament comprises a core-spun yarn in which staple fibers are spun over the second cut-resistant core filament.

9. The cut-resistant yarn structure according to claim 1 , further comprising one or more covering layers wound over the first covering yarn, wherein each of the one or more covering layers comprises polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, moisture management material, or a blended combination thereof.

10. The cut-resistant yarn structure according to claim 1 , further comprising one or more covering layers wound over the first covering yarn, wherein each of the one or more covering layers comprises fire retardant regenerated cellulose, polyimide, para-aramid, polyacrylonitrile (PAN), or a blended combination thereof.

11. A method of manufacturing a cut-resistant yarn structure, the method comprising:
providing a first cut-resistant core filament;
providing a second cut-resistant core filament;
spinning staple fibers over a third cut-resistant core filament to form a core-spun yarn wherein the core-spun yarn is a first covering yarn winding the first covering yarn over the first cut-resistant core filament and the second cut-resistant core filament; and spinning staple fibers over a fourth cut-resistant core filament to form a core-spun yarn, wherein the core spun yarn is a second covering yarn; and
winding the second covering yarn, along with the first covering yarn over the first cut-resistant core filament and the second cut-resistant core filament.

12. The method according to claim 11 , wherein the first cut-resistant core filament comprises one of basalt, steel, or steel alloy.

13. The method according to claim 11 , wherein the second cut-resistant core filament comprises one of basalt, steel, or steel alloy.

14. The method according to claim 11 , wherein the third cut-resistant core comprises one of basalt, steel, or steel alloy.

15. The method according to claim 11 , wherein the staple fibers of the core-spun yarn of the first covering yarn comprise polyester, PE series-polyester, polyethylene, high performance polyethylene (HPPE), high molecular weight polyethylene (HMWPE), regenerated cellulose, moisture management material, or a blended combination thereof.

16. The method according to claim 11 , wherein the staple fibers of the core-spun yarn of the first covering yarn comprise fire retardant regenerated cellulose, polyimide, para-aramid, polyacrylonitrile (PAN), or a blended combination thereof.

17. The method according to claim 11 , wherein providing the first cut-resistant core filament comprises spinning staple fibers over the first cut-resistant core filament to form a core-spun yarn.

18. The method according to claim 11 , wherein providing the second cut-resistant core filament comprises spinning staple fibers over the second cut-resistant core filament to form a core-spun yarn.
