Abstract
A seating structure including fabric support webs is provided. The seating structure includes a webbed support surface formed from a warp knit fabric with weft insertion of an elastomeric yarn. The stretch in the warp is substantially linear over a full range of applied stress from zero pounds to failure. The stretch in the weft has two substantially linear components wherein the first linear component operates over the range of zero to about 10 pounds applied force and the second linear component operates over the range of 10 pounds applied force to failure.
Claims9
A warp knit, weft-insertion elastomeric fabric structure having a performance side and an aesthetic side, the fabric structure comprising:
- a plurality of elastomeric monofilament yarns running in a first direction, said monofilament yarns lying in a first plane and forming the performance side of said fabric structure;
- a plurality of elastomeric wrapped filament yarns running in a second direction generally transverse to said first direction, said wrapped filament yarns lying in a second plane substantially parallel to said first plane and forming the aesthetic side of said fabric;
- and a plurality of knit filament yarns running between said first plane and said second plane and tying said elastomeric monofilament yarns to said elastomeric wrapped filament yarns.
A warp knit, weft-insertion elastomeric fabric structure having a performance side and an aesthetic side, the fabric structure comprising:
- a plurality of elastomeric monofilament yarns having a denier of about 2500 running in a first direction at a construction density of between about 12 and about 32 yarns per inch, said monofilament yarns lying in a first plane and forming the performance side of said fabric structure;
- a plurality of elastomeric wrapped filament yarns running in second direction generally transverse to said first direction at a construction density of between about 16 and about 24 yarns per inch, said elastomeric wrapped filament yarns lying in a second plane substantially parallel to said first plane and forming the aesthetic side of said fabric structure;
- and a plurality of knit filament yarns having a denier of between about 100 and about 250 running between said first plane and said second plane and tying said elastomeric monofilament yarns to said wrapped filament yarns.
