Artificial sueded leather being excellent in flame retardance and method of producing the same

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.

Waterborne polyurethane waterproof moisture-permeable coated fabric and preparation method thereof

The invention discloses a waterborne polyurethane waterproof moisture-permeable coated fabric and a preparation method thereof. The waterborne polyurethane coating is prepared from the following raw materials in parts by weight: 140-150 parts of polyester polyol, 20-24 parts of toluene diisocynate, 40-50 parts of diphenyl-methane-diisocyanate, 8-12 parts of 2,2-dimethylolpropionic acid, 7-9 parts of neopentyl glycol, 3-5 parts of trimethylolpropane, 6-10 parts of dibutyltin dilaurate, 4-6 parts of a DH-1 reinforcing agent, 2-3 parts of an antioxidant TNP, 9-11 parts of an ultraviolet absorbent, 8-12 parts of a dyeing agent, 6-7 parts of liquid paraffin, 4-5 parts of antimony trioxide, 5-7 parts of polytetrahydrofuran dibasic alcohol, 6-8 parts of nanosilicon dioxide, 0.8-1.2 parts of dicumyl peroxide, 7-9 parts of 2,6-Di-tert-butyl-4-methylphenol (BHT), 15-19 parts of deionized water and 7-9 parts of auxiliary. The coated fabric which is high in elongation at break and high in moisture and air permeability is prepared, and the properties such as the elongation at break, the moisture and air permeability, the aging resistance, the flame retardance and the electrostatic resistance of modified polyurethane can be effectively improved.
