  • Flame-retarded bedding product
    Patent number: 5506042
    Abstract: A flame-retarded bedding product comprising (A) 85 to 15 parts by weight of a fiber comprising a polymer containing 17 to 86% by weight of a halogen, and 6 to 50% by weight of an Sb compound based on the polymer, and (B) 15 to 85 parts by weight of at least one fiber selected from the group consisting of natural fibers and chemical fibers, the total amount of the fibers (A) and (B) being 100 parts by weight. The bedding product has not only the desired flame resistance but also excellent visual feeling, feeling of touchness, hygroscopic property, washing resistance, durability, and the like.
