The reaction time and reaction mechanism were determined by tracking the reaction process using ultraviolet spectrum.The cotton cloth finished with DCMA, by rolling baking process, when the flame retardant concentration from 10% to 30%.the smoldering time decreased from 3S to 1 S, carbon length decreased from 10.5 to 6.3, limiting oxygen index by 31 increased to 36.4.the tensile breaking strength of cotton fabric decreased from 6.46MPa to 3.12MPa.展开更多
