Patent number: 7611771Abstract: The flame retardant according to the present invention is prepared by complexing a flame retardant polyphosphate compound with a silicone resin. The silicone resin is applied to cover the particles of the polyphosphate compound. As the polyphosphate compound, it is preferred to use ammonium polyphosphate having a weight average polymerisation degree of 20 to 2000. By applying the flame retardant of the present invention on fibers as a flame retardant resin composition containing a binder resin, environmentally soft flame retardant textile products can be stably obtained.Type: GrantFiled: August 22, 2005Date of Patent: November 3, 2009Assignee: Kawashima Selkon Textiles Co., Ltd.Inventor: Kohei Ohara

Publication number: 20090214813Abstract: A flame retardant polymer fiber, a process for making such a fiber, and a material containing such fibers are provided. The flame retardant polymer fiber is a high tenacity fiber formed of a poly(trimethylene terephthalate) co-polymer containing a trimethylene terephthalate monomer and a phosphorous containing flame retardant monomer. The flame retardant PTT co-polymer fiber is produced by a process in which the trimethylene terephthalate monomer or its precursors and the phosphorous containing flame retardant monomer or its precursors are combined to form the PTT co-polymer in one or more pre-polymerization and polymerization steps, and the PTT co-polymer is spun into a fiber. Materials including such flame retardant PTT co-polymer fibers, e.g. carpets and textiles, are also provided.Type: ApplicationFiled: December 16, 2008Publication date: August 27, 2009Inventors: Robert Van Den Berg, Wouter Koen Harteveld, Hans Joachim Heinen, Thomas Paul Von Kossak-Glowczewski

Publication number: 20040185731Abstract: The present invention concerns a flame retardant (FR) nonwoven fabric useful in wall panels, especially for cubicles. The nonwoven fabric comprises from about 15 to 65 weight % of a low melt binder, and least one of FR rayon fiber, FR acrylic fiber, FR melamine fiber, or FR resin coated synthetic or natural fibers, and optional nonbonding fibers. The total amount of FR fibers and FR resin coated synthetic or natural fibers is about 30-85 wt. % of the fabric. The present invention also contemplates a wall panel constructed from the nonwoven fabric comprising FR rayon fibers, FR acrylic fibers, FR melamine fiber or a combination of these, and/or FR resin coated synthetic or natural fibers, with about 15 to about 65 weight % low melt binder. The wall panel from this construction passes the ASTM E 1354, 1999 tests. Preferably the nonwoven fabric has a batt weight of at least about 40 oz./sq. yd. and preferably between about 40 oz./sq. yd. and 60 oz./sq. yd.Type: ApplicationFiled: March 20, 2003Publication date: September 23, 2004Inventor: Sheri L.

Publication number: 20040092184Abstract: A flame-retardant substrate is present herein. The flame-retardant substrate includes a material layer surrounded by a flame-retardant coating. The coating is made of a chemical mixture that serves as a flame retardant barrier when exposed to fire. The flame-retardant substrate may be attached beneath the upholstery or surface layer of a textile-based item such as a piece of furniture or mattress. As such, the flame-retardant substrate serves as a barrier to flame to which the item is exposed while further impairing the further spread of fire.Type: ApplicationFiled: November 12, 2002Publication date: May 13, 2004Inventor: Rus Kingman

Patent number: 6723668Abstract: The cigar and cigarette burn resistant gaming cloth table includes a layer of fire retardant treated knit fabric laminated to a thin sheet of aluminum and wherein the other side of the aluminum sheet is laminated to a layer of non-woven synthetic fabric. Preferably, the top layer knit fabric is laminated to the aluminum via a latex adhesive. The lower non-woven fabric is laminated to the aluminum sheet via latex adhesive. Preferably, the knit layer, prior to being laminated to the thin sheet of aluminum, is treated with a fire retardant and an oil and water repellant chemical composition. Most preferably, the fire retardant and oil and water repellant chemical composition is a phosphorus fluorocarbon. The method includes treating the knit polyester fabric with fire retardant chemical, laminating a thin sheet of aluminum between the knit fabric layer and a layer of non-woven synthetic fabric. Preferably, the lamination is accomplished with a latex adhesive.Type: GrantFiled: June 1, 2001Date of Patent: April 20, 2004Assignee: Graph to Graphics, Inc.Inventor: Ivette Principe
