【Abstract】 The organic salt was synthesized from diethanolamine and phosphite, and the flame retardant was obtained by adjusting the organic salt solution to a certain pH with 28% ammonia. The flame retardancy, whiteness and breaking strength of the finished cotton fabric were tested. The results showed that the best synthesis process of the flame retardant was: 100 g diethanolamine, 100 g phosphite, 30 g water, 3.82 g 28% ammonia, reaction temperature 75 ℃, adding phosphite aqueous solution for 2.5 h, holding reaction temperature 75 ℃ and holding reaction 1 h; the best finishing process of the flame retardant was: 400 g/L flame retardant, baking temperature 110 ℃, baking time 2 min. After finishing, the continuous burning time of cotton fabric was 1.4 s, smoldering time was 0.2 s, damage length was 2.4 cm, whiteness was 80,breaking strength was 368 N/5 cm.更多还原
