Architectural covering with woven material
A covering for an architectural feature includes a woven material. The woven material is made at least partially from binder yarns to form a woven fabric. The binder yarns are heated after the fabric is woven to a temperature sufficient to cause the binder yarns to bond and fuse to adjacent yarns at crossover points. The woven material is inherently resistant to fraying and/or unraveling.
1. A woven material for use in architectural coverings that is inherently resistant to unraveling, said woven material comprising:
a non-laminated woven fabric having longitudinal edges and lateral edges, said woven fabric comprising warp yarns and weft yarns, said weft yarns intersecting with said warp yarns to define crossover points, at least some of said warp yarns and at least some of said weft yarns comprising binder yarns, said binder yarns defining an outer surface made from a low melting temperature polymer, wherein said binder yarns are bonded with adjacent yarns at said crossover points for preventing said woven fabric from unraveling along said longitudinal edges,
wherein the woven fabric is a sheer fabric.
2. The woven material as defined in claim 1 , wherein said woven fabric comprises interstitial openings between intersecting yarns.
3. The woven material as defined in claim 1 , wherein said binder yarns comprise monofilament yarns.
4. The woven material as defined in claim 1 , wherein said binder yarns comprise multifilament yarns.
5. The woven material as defined in claim 1 , wherein said binder yarns comprise spun yarns.
6. The woven material as defined in claim 5 , wherein said binder yarns are spun yarns having a yarn count of less than or equal to about Ne 200 and greater than or equal to about Ne 6.
7. The woven material as defined in claim 1 , wherein said binder yarns have a denier of less than or equal to about 600 and greater than or equal to about 10.
8. The woven material as defined in claim 1 , wherein said woven material is a sheer fabric, further wherein said binder yarns have a denier of less than or equal to about 30 and greater than or equal to about 10.
9. The woven material as defined in claim 1 , wherein all of said warp yarns and all of said weft yarns comprise said binder yarns.
10. The woven material as defined in claim 1 , wherein said low melting temperature polymer comprises a polyester polymer.
11. The woven material as defined in claim 1 , wherein said low melting temperature polymer has a melting point of less than or equal to about 220° C.
12. The woven material as defined in claim 1 , wherein the binder yarns are formed from monocomponent fibers.
13. The woven material as defined in claim 1 , wherein the binder yarns are formed from bi-component fibers.
14. The woven material as defined in claim 1 , wherein said woven fabric has a basis weight of greater than or equal to about 10 gsm and less than or equal to about 175 gsm.
15. The woven material as defined in claim 1 , wherein said woven fabric is a sheer fabric that has a basis weight of greater than or equal to about 10 gsm and less than or equal to about 28 gsm.
16. The woven material as defined in claim 1 , wherein said woven fabric has a yarn density such that there are greater than or equal to about 22 warp yarns per centimeter and less than or equal to about 38 warp yarns per centimeter and there are greater than or equal to about 22 weft yarns per centimeter and less than or equal to about 38 weft yarns per centimeter.
17. The woven material as defined in claim 1 , wherein the binder yarns are textured.
18. The woven material as defined in claim 1 , wherein said woven fabric has a plain basket weave.
19. The woven material as defined in claim 1 , wherein said binder yarns are solution dyed.
20. The woven material as defined in claim 1 , wherein the woven material has a longitudinal cut edge that is not cauterized.
21. An architectural covering comprising:
a facing layer spaced from a backing layer, a sheer woven material as defined in claim 1 comprising said facing layer or said backing layer of said architectural covering.
22. An architectural covering comprising:
a backing layer comprising a sheer woven material as defined in claim 1 , said backing layer extending in a longitudinal direction; and
a plurality of horizontally-oriented vane elements spaced along said longitudinal direction of said backing layer, each of said vane elements including first and second parallel edges that are perpendicular to said longitudinal direction, said second edge being moveable towards and away from said first edge for selectively controlling a spacing between the vane elements.
