Abstract :The production of flame retardant leather is significant for some leather types as aircraft and automotive upholstery leathers, and protective leathers as for motorcyclist jackets. For this reason, in this research it was aimed to modify effect of commercial flame retardant insert ignore into journalissuearticles values(CFR); on upholstery leathers treated with borax, boric acid and zinc borate. Control insert ignore into journalissuearticles values(group 1);, 200 g/L CFR insert ignore into journalissuearticles values(group 2);, 10 g/L borax + 60 g/L boric acid + 200 g/L CFR insert ignore into journalissuearticles values(group 3); and 10g/L zinc borate + 60 g/L boric acid + 200 g/L CFR insert ignore into journalissuearticles values(group 4); chemical solutions were applied to the leathers by padding finishing technique, and after the flame retardant application the leathers were finished with traditional finishing recipe. Flame retardant property of leathers was determined by vertical flammability insert ignore into journalissuearticles values(ISO 6941:2007); and limit oxygen index insert ignore into journalissuearticles values(LOI); insert ignore into journalissuearticles values(ASTM D 2863-77); fire resistance tests. In addition, the treated leathers were characterized by ATR-FTIR and SEM devices. According to LOI results, CFR CFR+borax+boric acid and CFR+zinc borate+boric acid treated groups of leather had 28.5%, 29.2% and 29.9% oxygen concentration respectively, while control sample had 27.0%. Flame retardant property of leathers was significantly enhanced by the effect of boron derivatives.
