Abstract: The present invention relates to a flame resistant fiber composite obtained by compounding: 20 to 85% by weight of a fiber (A) containing 0.5 to 50 parts by weight of an Sb compound to 100 parts by weight of a polymer containing halogen atom of not less than 17% by weight; 5 to 80% by weight of a heat-resistant fiber (B); 0 to 40% by weight of a cellulosic fiber (C); and 0 to 40% by weight of an inflammable fiber (D). Use of the composite in furniture, beddings, etc. in house increasingly improves flame resistance of materials, enabling use in fields requiring advanced flame resistance.

Abstract: There is provided a flame-retardant knit fabric which can exhibit texture and comfort inherent to materials such as cotton and urethane foam used for upholstered furniture such as a mattress and chair and bedding products such as a pillow, mattress pad and bedding, the flame-retardant knit fabric which can provide these products with high flame retardance. The internal structure of a mattress is covered with a flame-retardant knit fabric that comprises at least two fibers selected from the group consisting of (A) a halogen-containing fiber, (B) a cellulosic fiber, (C) a flame-retardant cellulosic fiber and (D) a polyester fiber, has a weight per unit area of at least 140 g/m2 and a thickness of at least 0.5 mm, and contains a flame retardant at a ratio of at least 2% by weight based on the while fabric.
