Abstract

A covering for an architectural opening, having a first layer with alternating relatively opaque stripes and relatively translucent stripes, and a second layer with alternating relatively opaque stripes and relatively translucent stripes. The first and second layers are positioned one behind the other, with the stripes substantially parallel. The first and second layers are movable relative to one another in a direction substantially perpendicular to the stripes. The covering also includes a series of parallel binder threads for attaching the first layer to the second layer. The binder threads run substantially perpendicular to the stripes, and thereby, one of the layers can be slid along the binder threads when moved relative to the other. The blind is preferred to be woven as a double-layer fabric.

Claims

1. An architectural covering, particularly a covering for an architectural opening such as a window, comprising:

2. The covering of claim 1 which has a plurality of parallel binder threads and a plurality of thin preshrunk warp threads in the first or second layer.

3. The covering of claim 2 wherein each warp thread, about which the binder thread forms a binder thread loop, is a think preshrunk warp thread.

4. The covering of claim 1 wherein each warp thread, about which the binder thread forms a binder thread loop, is a thin preshrunk warp thread.

5. The covering of claim 4 wherein the thickness of each thin preshrunk warp thread is 20 to 50% of the thickness of other warp threads of the covering.

6. The covering of claim 5 wherein the thickness of each thin preshrunk warp thread is about 30% of the thickness of other warp threads of the covering.

7. The covering of claim 3 wherein the thickness of each thin preshrunk warp thread is 20 to 50% of the thickness of other warp threads of the covering.

8. The covering of claim 7 wherein the thickness of each thin preshrunk warp thread is about 30% of the thickness of other warp threads of the covering.

9. The covering of claim 7 wherein each thin preshrunk warp thread is only in a rear, movable layer.

10. The covering of claim 4 wherein each thin preshrunk warp thread is only in a rear, movable layer.

11. The covering of claim 1 wherein each thin preshrunk warp thread is only in a rear, movable layer.

12. The covering of claim 11 wherein in a front layer, each binder thread forms a plurality of adjacent binder thread loops about adjacent warp threads.

13. The covering of claim 10 wherein in a front layer, each binder thread forms a plurality of adjacent binder thread loops about adjacent warp threads.

14. The covering of claim 9 wherein in a front layer, each binder thread forms a plurality of adjacent binder thread loops about adjacent warp threads.

15. The covering of claim 14 wherein the adjacent warp threads are separated from each other by a warp thread.

16. The covering of claim 13 wherein the adjacent warp threads are separated from each other by a warp thread.

17. The covering of claim 12 wherein the adjacent warp threads are separated from each other by a warp thread.

18. The covering of claim 3 wherein the adjacent warp threads are separated from each other by a warp thread.

19. The covering of claim 1 wherein the adjacent warp threads are separated from each other by a warp thread.

20. The covering of claim 19 wherein the adjacent warp threads are separated from each other by 1-3 warp threads.

21. The covering of claim 20 wherein the adjacent warp threads are separated from each other by just 1 warp thread.

22. The covering of claim 15 wherein the adjacent warp threads are separated from each other by 1-3 warp threads.
