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. A method of producing the artificial sueded leather as described above comprises imparting an 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, to one face of 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.
