Abstract: A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.

Abstract: A flame-retardant upholstered furniture includes an inner structure, and a flame-blocking fabric that covers the inner structure. The flame-blocking fabric contains flame-retardant modacrylic fibers (A) in an amount of 60 mass % or more and 90 mass % or less, and cellulose fibers (B) in an amount of 10 mass % or more and 40 mass % or less, with respect to the overall mass of the fabric. The flame-retardant modacrylic fibers (A) contain a magnesium compound. The flame-blocking fabric contains the magnesium compound in an amount of 1.5 mass % or more and 13.5 mass % or less with respect to the overall mass of the fabric. Time until both afterflame and afterglow go out of the flame-retardant upholstered furniture is 120 seconds or less when measured through a flammability test based on BS 5852: 2006.

Abstract: The present disclosure relates to a flame-retardant fabric that includes a modacrylic fiber and a cellulose fiber. The cellulose fiber is one or more selected from a regenerated cellulose fiber and a natural cellulose fiber. The flame-retardant fabric contains the modacrylic fiber in an amount of 65 to 90 wt % and the cellulose fiber in an amount of 10 to 35 wt % with respect to the overall weight of the fabric. The modacrylic fiber contains a magnesium compound inside the fiber. The flame-retardant fabric contains the magnesium compound in an amount of 2.5 to 4.5 wt %. Afterflame time and afterglow time of the flame-retardant fabric measured using a flammability test based on ISO 15025: 2000 are 2 seconds or less and 2 seconds or less, respectively.

Abstract: A flame-retardant modacrylic fiber including a modacrylic copolymer in an amount of 100 parts by mass, and a zinc stannate compound in an amount of 1 to 18 parts by mass, wherein the zinc stannate compound has an average particle size D50 of 0.5 μm or more is provided. Further, a flame-retardant fiber composite and a flame-retardant work clothing including the flame-retardant modacrylic fiber in an amount of 30 to 80 mass %, and one or more other fibers selected from the group consisting of natural fibers and chemical fibers in an amount of 20 to 70 mass % are provided.
