  • Publication number: 20090258182
    Abstract: It is intended to provide a novel artificial sueded leather having flame retardance, which is excellent inflame retardance, light resistance and abrasion resistance, suffers from no water spot and is free from any halogenated chemical (i.e., one having been treated with a so-called non-halogenated flame retardant), and a method of producing the same. The above artificial sueded leather comprises a thermoplastic synthetic fiber cloth made of a woven fabric, a knitted web or a nonwoven fabric, which has a raised-fiber or napped-fiber surface and has been impregnated with a polyurethane resin, and a flame retardant which contains at least a phosphate compound A having a solubility in water of 1% or less, a vinyl group-containing resin C capable of forming a carbonization skeleton in burning and a water-insoluble thickener D and is imparted to one face of the thermoplastic synthetic fiber cloth.

  • Patent number: 7588802
    Abstract: The invention provides a flame-retardant processing agent capable of imparting durable flame retardance to polyester-based fiber products without using halogen-based flame retardant. The flame-retardant processing agent is obtained by dispersing at least one phosphoric acid amide selected from the group consisting of 1,4-piperazinediyl bis(diarylphosphate), diaryl aminophosphate and aryl diaminophosphate as a flame retardant in a solvent in the presence of a nonionic surfactant or an anionic surfactant.
