摘　　要：为了制备一种同时含有多种阻燃元素的莱赛尔纤维用阻燃剂,采用磷酸和尿素在高温下对二羟甲基二羟基乙烯脲进行改性处理,得到了一种同时含有氮和磷2种阻燃元素的阻燃剂,并用其对莱赛尔纤维进行阻燃整理.通过优化阻燃剂和催化剂的密度、浸泡时间、整理液的pH、焙烘温度以及焙烘时间等影响因素,使得阻燃整理后的莱赛尔纤维其极限氧指数达到36%,断裂强度达到2.80 cN,且经10 g/L碳酸钠和25℃及90℃水洗30 min后仍具有较好的阻燃性能.In order to prepare a flame retardant for Lyocell fiber containing multiple flame retardant elements at the same time,dimethylol dihydroxy ethylene urea was modified by phosphoric acid and urea at high temperature to obtain a flame retardant agent containing nitrogen and phosphorus at the same time,and the flame retardant finishing of Lyocell fiber was carried out with it.By optimizing the concentration of flame retardants and catalysts,soaking time,pH of finishing solution,baking temperature and baking time,the limiting oxygen index and breaking strength of the flame-retardant finished Lyocell fiber reached 36%and 2.80 CN,and it still has good flame retardancy after washing with 10 g/L sodium carbonate and at 25℃and 90℃for 30 min.
