Abstract: Liquid phosphate ester flame retardants were applied onto polyester / cotton fabric at a loading of 5wt% based on dry fabric via impregnation, resulting a fabric with B level of United States FMVSS-302 standard. Six flame retardants were introduced into polyurethane to study the fire retardant effect. It was found that aluminum hydroxide/resorcinol dual/phosphate (12/2/2 by weight) composite fire retardant system may result in a combustion rate of 0 mm / min, achieving A level, from which environment-friendly, fire-retardant synthetic leather could be produced.

Key words: polyurethane, synthetic leather, flame retarding agents, flame retardency
