As can be seen from the table, flame retardant wool, when the amount of flame retardant to a certain extent, wool growth rate decreases with varying concentrations. This is due to a specific flame retardant wool wool for Shandong, -NH 3 + wool on the total number of positive ions is constant, when the flame retardant concentration reaches a certain value, its remaining -NH + 3 the relative amount of positive ions is reduced to a certain extent, it continues to increase the concentration of the growth rate has little effect. Therefore, the concentration generally choose 2 to 3 percent that is sufficient to meet flame retardant requirements. Shandong Antai New Material Technology Co., Ltd.
