Abstract
A flame-resistant fabric for shelters including a flame-resistant interior layer, an flame-resistant, insulating middle layer adjacent the interior layer, a flame-resistant exterior layer adjacent the insulating middle layer, and at least one threaded seam quilting the insulating middle layer between the interior layer and the exterior layer to form a flame-resistant fabric. The flame-resistant fabric is capable of being formed into a flame-resistant, insulated shelter for use in extreme weather.
Claims33
A shelter comprising:
- at least one wall made of flame-resistant fabric, the flame-resistant fabric comprising:
- a flame-resistant interior layer;
- a flame-resistant, insulating middle layer adjacent the interior layer, the middle layer comprising a blend of modacrylic, aramid, and polyester fibers;
- a flame-resistant exterior layer adjacent the insulating middle layer;
- and
- a threaded stitch quilting the insulating middle layer between the interior layer and the exterior layer to form a quilted flame-resistant fabric, the threaded stitch being repeated at a regular interval to produce at least three parallel quilt lines extending along an entire length of the fabric;
- and
- an opening in the wall for entering and exiting the shelter.

A shelter comprising:
- a collapsible and erectable frame;
- a ceiling and a plurality of side walls attached to and surrounding the frame to form a shelter, the ceiling and side walls made of flame-resistant fabric, the flame-resistant fabric comprising:
- a flame-resistant interior layer;
- a flame-resistant, insulating middle layer adjacent the interior layer, the middle layer comprising a blend of modacrylic, aramid, and polyester fibers;
- a flame-resistant exterior layer adjacent the insulating middle layer;
- and
- a threaded stitch quilting the insulating middle layer between the interior layer and the exterior layer to form a quilted flame-resistant fabric, the threaded stitch being repeated at a regular interval to produce at least three parallel quilt lines extending along an entire length of the fabric;
- and
- an opening in at least one side wall for entering and exiting the shelter.

A method of making a shelter, the method comprising the steps of:
- placing a flame-resistant, insulating middle layer between a flame-resistant interior layer and a flame-resistant exterior layer, the middle layer comprising a blend of modacrylic, aramid, and polyester fibers;
- quilting the middle layer between the interior layer and the exterior layer with a threaded stitch to form a flame-resistant fabric;
- repeating the step of quilting the middle layer between the interior layer and the exterior layer with a threaded stitch to produce at least three parallel quilt lines extending along an entire length of the fabric;
- and
- forming the flame-resistant fabric into a shelter.
