Abstract

A hybrid fiber which includes: a metal wire having a roughened surface; and a fiber is provided. In the hybrid fiber, the metal wire and the fiber are combined.

First claim

What is claimed is:

1. A hybrid fiber, comprising:
a metal wire having a roughened surface; and
a fiber,
wherein the metal wire and the fiber are combined, and
the metal wire has surface roughness Ra in a range from 0.15 μm to 0.25 μm.

2. The hybrid fiber according to claim 1 ,
wherein the metal wire is a tungsten wire.

3. The hybrid fiber according to claim 1 ,
wherein the metal wire has a diameter smaller than a diameter of the fiber.

4. The hybrid fiber according to claim 1 ,
wherein the metal wire is wound around the fiber as a core thread forming a covered yarn.

5. The hybrid fiber according to claim 1 ,
wherein the metal wire and the fiber are twisted together forming a piled yarn.

6. The hybrid fiber according to claim 1 ,
wherein the fiber is at least one of an aramid fiber and a nylon fiber.

7. A hybrid fiber, comprising:
a metal wire having a roughened surface; and
a fiber,
wherein the metal wire and the fiber are combined,
the metal wire is a tungsten wire, and
the metal wire has a diameter smaller than a diameter of the fiber.

8. The hybrid fiber according to claim 7 ,
wherein the metal wire is wound around the fiber as a core thread forming a covered yarn.

9. The hybrid fiber according to claim 7 ,
wherein the metal wire and the fiber are twisted together forming a piled yarn.

10. The hybrid fiber according to claim 7 ,
wherein the fiber is at least one of an aramid fiber and a nylon fiber.

11. A hybrid fiber, comprising:
a metal wire having a roughened surface; and
a fiber,
wherein the metal wire and the fiber are combined, and
the metal wire is wound around the fiber as a core thread forming a covered yarn.

12. The hybrid fiber according to claim 11 ,
wherein the metal wire is a tungsten wire.

13. The hybrid fiber according to claim 11 ,
wherein the fiber is at least one of an aramid fiber and a nylon fiber.
