Abstract

The present invention relates to a power transmission belt containing a frictional power transmission part and a fiber member that covers a surface of the frictional power transmission part, in which the fiber member is formed of a fiber (A) containing a water-absorbent fiber (A1) and contains a surfactant, to a fiber member used in the power transmission belt, and to a method for manufacturing the fiber member.

First claim

The invention claimed is:

1. A power transmission belt comprising a frictional power transmission part and a fiber member that covers a surface of the frictional power transmission part, wherein the fiber member includes a main body formed of a fiber (A) comprising a water-absorbent fiber (A 1 ) and a nonionic surfactant attached to the main body, wherein a melting point of the nonionic surfactant is 20° C. or lower.

2. The power transmission belt according to claim 1 , wherein the water-absorbent fiber (A 1 ) comprises a cellulose-based fiber.

3. The power transmission belt according to claim 1 , wherein the water-absorbent fiber (A 1 ) comprises a cotton fiber.

4. The power transmission belt according to claim 1 , wherein the water-absorbent fiber (A 1 ) has a proportion of 1% by mass or more in the entire fiber (A).

5. The power transmission belt according to claim 1 , wherein the fiber (A) further comprises a non-water-absorbent fiber (A 2 ).

6. The power transmission belt according to claim 5 , wherein the non-water-absorbent fiber (A 2 ) comprises a stretchable fiber.

7. The power transmission belt according to claim 5 , wherein the water-absorbent fiber (A 1 ) and the non-water-absorbent fiber (A 2 ) has a ratio of the former/the latter (mass ratio)=99/1 to 5/95.

8. The power transmission belt according to claim 1 , wherein the fiber member is a knitted fabric.

9. The power transmission belt according to claim 1 , wherein the fiber member is a knitted fabric that is knitted by weft knitting.

10. The power transmission belt according to claim 1 , wherein the surfactant has a content of from 1 to 100 g per 1 m 2 of the fiber member.

11. The power transmission belt according to claim 1 , wherein the frictional power transmission part is formed of a rubber.

12. The power transmission belt according to claim 1 , wherein the power transmission belt further comprises a tension layer that forms a belt back face, a compression layer formed on one side of the tension layer, and a tension member embedded along a belt longitudinal direction between the tension layer and the compression layer and the compression layer has the frictional power transmission part.

13. The power transmission belt according to claim 1 , which is a V-ribbed belt.

14. The power transmission belt according to claim 1 , wherein the frictional power transmission part has a contact angle of from 0 to 30°, after a lapse of 5 seconds from dropwise addition of water onto its surface.

15. The power transmission belt according to claim 1 , wherein the nonionic surfactant is a polyethylene glycol-type surfactant.

16. A fiber member for covering a surface of a frictional power transmission part constituting a power transmission belt, wherein the fiber member includes a main body formed of a fiber (A) comprising a water-absorbent fiber (A 1 ) and a nonionic surfactant attached to the main body, wherein a melting point of the nonionic surfactant is 20° C. or lower.

17. The fiber member according to claim 16 , wherein the nonionic surfactant is a polyethylene glycol-type surfactant.

18. A method for manufacturing the fiber member described in claim 16 , which comprises a step of immersing the main body of the fiber member formed of the fiber (A) containing the water-absorbent fiber (A 1 ) in a solution containing the surfactant.

19. The manufacturing method according to claim 18 , wherein the solution has a concentration of the surfactant of from 0.3 to 50% by mass.

20. The manufacturing method according to claim 18 , wherein the nonionic surfactant is a polyethylene glycol-type surfactant.
