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.
Claims29
An architectural covering, particularly a covering for an architectural opening such as a window, comprising:
- a first fabric layer;
- and
- a second fabric layer that is parallel and adjacent to the first layer and substantially coincident with the first layer;
- the second layer being capable of movement relative to the first layer in a direction parallel to the first layer;
- and
- a binder thread, between the layers, connecting them and extending in the direction of movement of the second layer;
- the second layer being slidable along the binder thread during the movement of the second layer relative to the first layer;
- wherein:
- the binder thread is a weft thread which forms at least one binder thread loop, about, a warp thread of each portion of the first and second layers, to which the binder thread is connected;
- and
- wherein the first or second layer, a warp thread, about which the binder thread forms a binder thread loop, is a thin preshrunk warp thread.
