Woven articles from synthetic self twisted yarns
View Patent ↗A woven panel is formed from a plurality of elongated yarns, with and without a center core. The core yarns provide mechanical strength for the woven material in supporting the coreless yarns when used in load bearing articles such as the seat or back portions of an article of furniture.
1. An article of furniture having a simulated natural wicker appearance adapted for supporting a person, said article comprising:
a frame having the shape of an article of furniture, said frame including at least a seat portion and a back rest portion formed from said frame for supporting a person in a seated position, and
a woven panel attached to at least one of said seat portion and said back portion formed by said frame, said woven panel forming a supporting portion when attached to one of said seat portion and said back portion adapted to support a person when in a seated position, said woven panel comprising a plurality of elongated synthetic polymer first yarns woven together with a plurality of elongated synthetic polymer second yarns having substantially elliptical cross sections and a longitudinal axis, said synthetic polymer second yarns each comprising a single yarn including an elongated body having a helical shape in said woven panel by being self twisted into either an S-twist or Z-twist about its longitudinal axis prior to forming said woven panel, wherein said helical shape of said synthetic polymer second yarns is visible in said woven panel.
2. The article of furniture of claim 1 , wherein said plurality of synthetic polymer first yarns comprise a composite yarn of at least a first and second synthetic polymer yarn twisted together over their length.
3. The article of furniture of claim 1 , wherein said first and second yarns are at least partially adhered to each other over their length.
4. The article of furniture of claim 1 , wherein said first yarns are different from said second yarns in at least one of color, configuration, surface ornamentation, shape and size.
5. The article of furniture of claim 1 , wherein at least one of said first and second yarns includes at least one node extending uninterrupted longitudinally along the entire length thereof.
6. The article of furniture of claim 1 , wherein said first and second yarns are at least partially adhered to each other at the interstices formed between said first and second yarns within said woven panel.
7. The article of furniture of claim 1 , wherein a plurality of said second yarns include at least one groove in the outer surface of said second yarns extending substantially in a longitudinal direction along the length thereof.
8. The article of furniture of claim 7 , wherein said second yarns having said groove have a deformed outer surface and a non-uniform cross-section over their length.
9. The article of furniture of claim 1 , wherein a plurality of said second yarns include at least one visual representation of a stripe on the outer surface of said second yarns extending substantially in a longitudinal direction along the length thereof.
10. The article of furniture of claim 9 , wherein said second yarns having said stripe have a deformed outer surface and a non-uniform cross-section over their length.
11. The article of furniture of claim 1 , wherein said first yarns comprise self-twisted yarns.
12. The article of furniture of claim 1 , wherein said seat portion is formed from said frame having at least lateral side members and front and back members spanning said side members, wherein said support element is attached to said side members and said front and back members, and is extending substantially unsupported therebetween.
13. The article of furniture of claim 1 , wherein said synthetic polymer first yarn is a core yarn.
14. The article of furniture of claim 1 , wherein said synthetic polymer second yarn is a core yarn.
15. The article of furniture of claim 1 , wherein said synthetic polymer second yarns include one or more of a node, a non-uniform surface, and a non-uniform cross-section.
16. The article of furniture of claim 1 , wherein said synthetic polymer second yarns include a node.
17. The article of furnishing of claim 1 , wherein said synthetic polymer second yarns have substantially cylindrical cross sections.
18. An article of furniture having a simulated natural wicker appearance adapted for supporting a person, said article comprising:
a frame having the shape of an article of furniture supported by a plurality of legs, said frame including at least a seat portion and a back rest portion formed from said frame for supporting a person in a seated position, and
a woven panel attached to at least one of said seat portion and said back portion formed by said frame, said woven panel forming a supporting portion when attached to one of said seat portion and said back portion adapted to support a person when in a seated position, said woven panel comprising a plurality of elongated synthetic polymer first yarns woven together with a plurality of elongated synthetic polymer second yarns having a longitudinal axis, said synthetic polymer second yarns each comprising a single yarn having a substantially elliptical cross section and including an elongated body having a continuous helical shape in said woven panel by being self twisted into either an S-twist or Z-twist about its longitudinal axis along the entire length of said yarn prior to forming said woven panel, wherein said helical shape of said synthetic polymer second yarns is visible to the naked eye in said woven panel.
19. The article of furniture of claim 18 , wherein said synthetic polymer second yarns include one or more of a node, a non-uniform surface, and a non-uniform cross-section.
20. The article of furniture of claim 18 , wherein said synthetic polymer second yarns include a node.
21. The article of furniture of claim 18 , wherein said synthetic polymer second yarns have substantially cylindrical cross sections.
