  • Patent number: 6670001
    Abstract: A sufficiently flame-retardant fabric for ink-jet recording with an ink accepting layer on its one side at least, the ink acceptability (ink holding capability) of which is the same as that of its non-flame-retardant counterpart, allowing the fabric to render highly deep/brilliant shade and sharp color images. The flame-retardant fabric for ink-jet recording includes a flame retarded fiber substrate with an ink accepting layer on its one side at least, which is made up of a 3-12 &mgr;m-thick top sub-layer and a bottom sib-layer with a flame retarding agent contained only in the bottom sub-layer wherein the flame retarding agent has its active ingredient applied to the substrate in an aqueous dispersion, accounting for 4 to 30% of the entire ink accepting layer by weight.

  • Publication number: 20030114070
    Abstract: A non-woven fabric which consists of a blend 75% to 95% by weight of polypropylene based fibers and 5 to 25% by weight of polyester based fibers. The polypropylene fibers are extruded from a melt mixture of about 80 to 99% by weight polypropylene and about 1 to 20% by weight of a suitable heat stabilizer. The polyester based fibers are extruded from a melt mixture of 80% to 100% by weight polyester and 0 to 20% by weight of other stabilizers and/or fire retardants. The flame retardant compounds are added to and blended with the polyester melt prior to the extrusion of the polyester based fibers. Most preferably, the extruded polypropylene and polyester based fibers are staple fibers of between about 2 and 12 denier.

  • Patent number: 5942006
    Abstract: A process for the flame-retardant treatment of a cellulosic fabric by impregnating a fabric with an aqueous solution of a tetrakis (hydroxyorgano) phosphonium (THP) and then at least partially drying it. The partially dried impregnated fabric is passed at a speed of 30 to 100 m/minute once through a chamber containing ammonia for a single cure. Both the moisture contained in the fabric and water produced as a by-product of curing are volatilized and condensed on an interior wall of the chamber and flow down the walls to a drain for removal of the condensed water from the apparatus. The process further includes measuring the rate of ammonia in the gas fed into the chamber, determining the ammonia content of the gas and measuring the temperature within the chamber, for maintaining the initial concentration of ammonia in the gas at 70% to 90% by volume and for maintaining the ratio of ammonia input to the THP composition in the range of at least 1.

    Abstract: The invention relates to coating compositions for producing watertight, vapor-permeable and flame-retardant coatings, comprising a vinyl chloride copolymer or vinyl acetate/ethylene dispersion, flameproofing agents, foam stabilizer and optionally crosslinkers. The invention further relates to a process for producing watertight, vapor-permeable and flame-retardant coatings by mechanically foaming the coating composition to produce a stable foam, applying the foam to a woven, knitted or nonwoven support material on one or both of the sides and drying it at a temperature of from 60.degree. to 180.degree. C. and optionally, after drying, compressing the foam layer. The textile support materials coated with the coating composition are suitable for use in building protection and in the geotextile sector.
