Abstract

An industrial textile has two layers, a web-side layer and a wear-side layer. The web-side layer has machine direction yarns ( 1 ) and binding cross-machine direction yarns ( 5 ). The wear-side layer has machine direction yarns ( 3 ) and cross-machine direction yarns ( 4 ). The binding cross-machine direction yarns ( 5 ) extend from the web-side layer to the wear-side layer and bind a portion of the wear-side layer machine direction yarns ( 3 ) to bond the web-side layer and the wear-side layer together, and wherein the web-side layer is a non-plain weave.

First claim

We claim:

1. An industrial textile comprising:
two layers, a web-side layer and a wear-side layer,
wherein the web-side layer comprises machine direction yarns and binding cross-machine direction yarns;
wherein the wear-side layer comprises machine direction yarns and cross-machine direction yarns;
wherein the binding cross-machine direction yarns extend from the web-side layer to the wear-side layer and bind a portion of the wear-side layer machine direction yarns to bond the web-side layer and the wear-side layer together, and wherein a weave of the web-side layer is configured to change during a pattern repeat, and
wherein the binding cross-machine direction yarns are configured to bind the web-side layer machine direction yarns in a five-shaft weave over one, under one, over one and under two web-side layer machine direction yarns.

2. The industrial textile of claim 1 , wherein the web-side layer machine direction yarns and the wear-side layer machine direction yarns are partially or fully unstacked.

3. The industrial textile of claim 1 wherein the binding cross-machine direction yarns bind the portion of the wear-side layer machine direction yarns while the binding cross-machine direction yarns bind the web-side layer machine direction yarns under two web-side layer machine direction yarns.

4. The industrial textile of claim 1 , wherein the binding cross-machine direction yarns are configured to bind every fifth of the wear-side layer machine direction yarns.

5. The industrial textile of claim 1 , wherein the binding cross-machine direction yarns bind a portion of the wear-side layer machine direction yarns to form binding points under the web-side layer.

6. The industrial textile of claim 1 , wherein the binding cross-machine direction yarns are configured to form a continuous independent yarn path.

7. The industrial textile of claim 1 , wherein the web-side layer comprises cross-machine direction yarns configured to only bind the web-side layer machine direction yarns.

8. The industrial textile of claim 7 , wherein at least one of the web-side layer cross-machine direction yarns is configured between two adjacent binding cross-machine direction yarns.

9. The industrial textile of claim 7 , wherein the web-side layer cross-machine direction yarns are configured to bind the web-side layer machine direction yarns over one, under one, over one and under two machine direction yarns.

10. The industrial textile of claim 1 , wherein the wear-side layer is a five-shaft weave or a ten-shaft weave.

11. The industrial textile of claim 10 , wherein the wear-side layer is a five-shaft weave and wherein the wear-side layer cross-machine direction yarns are configured to bind the wear-side layer machine direction yarns over one and under four machine direction yarns.

12. The industrial textile of claim 10 , wherein the wear-side layer is a ten-shaft weave and wherein the wear-side layer cross-machine direction yarns are configured to bind the wear-side layer machine direction yarns over two and under eight machine direction yarns.

13. The industrial textile of claim 10 , wherein the wear-side layer is a ten-shaft weave and wherein the wear-side layer cross-machine direction yarns are configured to bind the wear-side layer machine direction yarns over one, under one, over one and under seven machine direction yarns.

14. The industrial textile of claim 10 , wherein the wear-side layer is a ten-shaft weave and wherein the wear-side layer cross-machine direction yarns are configured to bind the wear-side layer machine direction yarns over one, under two, over one and under six machine direction yarns.

15. The industrial textile of claim 1 , wherein the ratio of the web-side layer machine direction yarns to the wear-side layer machine direction yarns is 1:1, 1:2 or 2:1.

16. The industrial textile of claim 1 , wherein the ratio of the web-side layer cross-machine direction yarns to the wear-side layer cross-machine direction yarns is 3:2, 2:1, 1:1, 1:2, 2:3 or 8:5.

17. An industrial textile comprising:
two layers, a web-side layer and a wear-side layer,
wherein the web-side layer comprises machine direction yarns and binding cross-machine direction yarns;
wherein the wear-side layer comprises machine direction yarns and cross machine direction yarns;
wherein the binding cross-machine direction yarns extend from the web-side layer to the wear-side layer and bind a portion of the wear-side layer machine direction yarns to bond the web-side layer and the wear-side layer together, and
wherein a weave of the web-side layer is configured to change during a pattern repeat, and
wherein the binding cross-machine direction yarns are configured to bind the web-side layer machine direction yarns in a six-shaft weave under one, over one, under two, over one, under one, over one, under two, over one, under one and over one web-side layer machine direction yarns.

18. The industrial textile of claim 17 , wherein the web-side layer machine direction yarns and the wear-side layer machine direction yarns are partially or fully unstacked.

19. An industrial textile comprising:
two layers, a web-side layer and a wear-side layer,
wherein the web-side layer comprises machine direction yarns and binding cross-machine direction yarns;
wherein the wear-side layer comprises machine direction yarns and cross machine direction yarns;
wherein the binding cross-machine direction yarns extend from the web-side layer to the wear-side layer and bind a portion of the wear-side layer machine direction yarns to bond the web-side layer and the wear-side layer together, and
wherein a weave of the web-side layer is configured to change during a pattern repeat, and
wherein the binding cross-machine direction yarns are configured to bind the web-side layer machine direction yarns in an eight-shaft weave under two, over one, under one, over one, under two, over one web-side layer machine direction yarns.

20. The industrial textile of claim 19 , wherein the web-side layer machine direction yarns and the wear-side layer machine direction yarns are partially or fully unstacked.
