  • Publication number: 20070224405
    Abstract: This invention relates to a thin reinforced nonwoven fabric for fire blocking an article, articles containing such fabrics, and methods for making the fabrics and fire blocking the articles. When exposed to heat or flame, the fabric is capable of increasing its thickness by at least three times. The fabric comprises an open mesh scrim having a having crimped, heat-resistant organic fibers compressed thereon and held in a compressed state by a thermoplastic binder. When subjected to high heat or flame, the binder in the structure softens and flows, releasing the restrained crimped fibers and allowing the thickness of the fabric to increase dramatically.

  • Publication number: 20070199494
    Abstract: This invention relates to a multilayer spunlaced nonwoven composite useful as a fire blocking component for an article, an article such as furniture or a mattress comprising the nonwoven composite, and processes for making the nonwoven composite and fire blocking an article with the nonwoven composite. The multilayer nonwoven composite comprises a first layer comprising 75 to 25 weight percent regenerated cellulosic fiber that retains at least 10 percent of its fiber weight when heated in air to 700° C. at a rate of 20 degrees C. per minute and 25 to 75 weight percent heat-resistant fiber, said first layer having a basis weight of from 1 to 5 ounces per square yard (34 to 170 grams per square meter); and a second layer comprising up to 75 weight percent of a regenerated cellulosic fiber that retains at least 10 percent of its fiber weight when heated in air to 700° C. at a rate of 20 degrees C.

  • Publication number: 20060048302
    Abstract: This invention relates to a fabric composite for use in fire-blocking a mattress, a fire-blocked mattress set, and a process for fire-blocking mattresses; the fabric composite comprising, in order, (a) sacrificial outer ticking, (b) sacrificial cushioning material, and (c) fire-blocking fabric, the fire-blocking fabric being a single layer of nonwoven fabric comprising at least 0.5 ounces per square yard (17 grams per square meter) of a cellulose fiber that retains at least 10 percent of its fiber weight when heated in air to 700 C at a rate of 20 degrees C. per minute, and at least 0.5 ounces per square yard (17 grams per square meter) of a heat-resistant fiber. Mattress sets fire-blocked with this fabric composite have a peak heat release rate of less than 150 kilowatts within 30 minutes, preferably less that 150 kilowatts within 60 minutes, and a total heat release of less than 25 megajoules within 10 minutes when tested according to Technical Bulletin 603 of the State of California.
