  • Publication number: 20090311933
    Abstract: A low-resilience urethane foam cushion that is comfortable and has high flame retardancy. It sufficiently retains the unique texture and comfort inherent in low-resilience urethane foam materials for use as cushions or pillows. It further retains the intact excellent texture, touch feeling, and other properties inherent in fibrous materials. The low-resilience urethane foam cushion is obtained by covering a low-resilience urethane foam with a flame-barrier fabric made of at least two members selected from the group consisting of halogenated fibers (A), flame-retardant cellulosic fibers (B), cellulosic fibers (C), and polyester fibers (D), wherein the sum of (A) and (B) is 25 to 75 wt. % of the flame-barrier fabric, the sum of (B) and (C) is 30 wt. % or more of the flame-barrier fabric, the amount of (C) alone is up to 75 wt. % of the flame-barrier fabric, and the amount of (D) alone is up to 30 wt. % of the flame-barrier fabric.

  • Publication number: 20090025144
    Abstract: The object of the present invention is to provide a bedding in which polyester having excellent elasticity is used for a batting therein, and which is provided with high-grade flame retardance so as to withstand long-time flaming, even though only a small amount of a halogen-containing fiber is used therein. By configuring the flame-retardant bedding product so that it is composed of a batting and a ticking for covering the batting and that the batting comprises a cellulose fiber (A), a polyester fiber (B), and a halogen-containing fiber (C) as essential components, the bedding product is caused to achieve the above-described object. In addition to the excellent flame retardance, the bedding product of the present invention is allowed to have excellent cushiony properties, since a large amount of a polyester fiber can be used therein because the amount of a halogen-containing fiber used therein is relatively small.
