Abstract
A fire-resistant fabric suitable for use as a flame barrier comprising a flame durable textile fabric substrate formed of corespun yarns, the yarns comprising a core of flame resistant filament and a sheath of staple fibers, and an intumescent coating carried by one surface of the textile fabric substrate. In normal use, the fabric is flexible and conformable and has good air porosity. When exposed to high temperature and/or a flame, however, the intumescent coating reacts and swells to form a char which closes the pores or interstices of the fabric to thus prevent flame or hot gases from penetrating therethrough.
Claims43
A fire-resistant fabric suitable for use as a flame barrier, and comprising:
- a flame durable textile fabric substrate formed of corespun yarns, said yarns comprising a core of a flame resistant filament and a sheath of staple fibers, and an intumescent coating carried by one surface of said textile fabric substrate.
A fire-resistant fabric suitable for use as a flame barrier, and comprising:
- a flame durable knitted textile substrate formed of intermeshed corespun yarns, said yarns comprising a core of a flame resistant fiberglass filament and a sheath of staple fibers, and an intumescent coating comprising a carbonific compound, a catalyst and a source of non-flammable gas, said intumescent coating carried by one surface of said textile fabric substrate.
A fire resistant laminate comprising an underlying flammable layer, a flame barrier fabric overlying said flammable layer, said flame barrier fabric comprising a flame durable knitted textile fabric substrate formed of intermeshed corespun yarns, said yarns comprising a core of a flame resistant fiberglass filament and a sheath of staple fibers, an intumescent coating carried by one surface of said knitted textile fabric, and a decorative surface fabric overlying said flame barrier fabric, said intumescent coating contacting the decorative surface fabric layer.
A method of producing a fire-resistant fabric suitable for use as a flame barrier, said method comprising:
- (a) forming a flame durable textile fabric substrate from corespun yarns having a core of a flame resistant filament and a sheath of staple fibers,
- (b) applying to one surface of the textile fabric substrate an intumescent coating comprising a carbonific compound, a catalyst and a source of a non-flammable gas, and
- (c) curing the coating to produce a fire-resistant fabric.
A method of producing a fire-resistant laminate comprising:
- (a) forming a flame durable textile fabric substrate from corespun yarns having a core of a flame resistant filament and a sheath of staple fibers,
- (b) applying to one surface of the textile fabric substrate an intumescent coating comprising a carbonific compound, a catalyst and a source of a non-flammable gas, and
- (c) bonding a decorative surface fabric to the textile fabric substrate, the intumescent coating contacting the decorative outer fabric.
