Abstract

The object of the present invention is to provide a highly fire resistant fiber sheet and a molded fiber sheet thereof. The fibers of the fire resistant sheet of the present invention contain expandable graphite. When said expandable graphite is exposed to high temperatures, it will expand, giving self-extinguishing properties to said fiber sheet. Since said fire resistant molded fiber sheet is highly fire resistant and nontoxic to humans and animals, it is useful for car or building interiors, and the like.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a fire resistant fiber sheet and a molded fiber sheet thereof, used for car or building interiors, and the like. BACKGROUND OF THE INVENTION

[0002] Hitherto, for instance, needled nonwoven fabric, or needled felt, which are made by needle punching intertwining fibers, and resin nonwoven fabric, or resin felt, which is made by binding fibers with synthetic resin, or fiber knitting and fabric, and the like have been provided.

[0003] JP 11-61616 JP 8-39596

[0004] In said fiber sheet, fire resistance as well as sound proof and insulation properties are necessary.

[0005] To give said fiber sheet a fire resistance property, a fire retardant, such as tetrachlorophthalic acid, tetrabromophthalic acid, tetrabromobis phenol A, antimony trioxide, chlorinated paraffin, and the like are contained in said fiber sheet.

[0006] Said fire retardants cannot, however, guarantee an adequate fire resistance of said fiber sheet, and are feared...
