Abstract
The present invention is directed to a fabric composed of nylon or polyester fibers and having both liquid barrier properties and fire retardant properties without sacrificing many of the desirable properties of the fabric. In particular, the present invention helps overcome many of the disadvantages associated with prior art fabrics by providing a fabric having feel and drape of a textile fabric while having good fluid barrier characteristics and fire retardant characteristics. In one embodiment, the invention is also directed to a breathable nylon or polyester fabric having liquid barrier and fire retardant properties. The present invention also provides methods of making such fabrics.
Claims20
A fire resistant fabric that is resistant to water and permeable to moisture vapor, comprising:
- a woven fabric substrate formed of polyester or nylons fibers;
- a fluid saturant impregnating the fabric and covering the surfaces of the fibers, the fluid saturant comprising a fire resistant oligimer and an oil and water repellent composition;
- and
- a layer of fire resistant polyurethane coating covering at least one surface of the fabric substrate, the polyurethane coating comprising polyurethane;
- a thermally degradable aromatic halogen containing compound;
- an antimony oxide;
- and a metal hydroxide, wherein the fabric has a moisture vapor transmission rate of at least 600 g/m2/day and a hydrohead of at least 30 cm.
A fire resistant fabric comprising:
- a woven fabric substrate formed of polyester or nylons fibers;
- a fluid saturant impregnating the fabric and covering the surfaces of the fibers, the fluid saturant comprising a fluoroalkyl acrylate copolymer and thiourea formaldehyde;
- and
- a layer of fire resistant polyurethane coating covering at least one surface of the fabric substrate, the polyurethane coating comprising polyurethane;
- a thermally degradable aromatic halogen containing compound;
- barium metaborate monohydrate;
- and a metal hydroxide.
A method of forming a flame-retardant substrate comprising steps of:
- providing a piece of woven fabric composed of nylon or polyester fibers;
- impregnating the fabric with a composition comprising a fire resistant oligimer and an oil and water repellent composition;
- applying heat to the fabric at a rate sufficient to cure the composition;
- and
- coating at least one surface of the fabric with a polyurethane layer comprising polyurethane;
- a thermally degradable aromatic halogen containing compound;
- barium metaborate monohydrate or antimony oxide;
- and a metal hydroxide.
