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.
