The invention belongs to the field of cellulose materials, and relates to a preparation method of flame-retardant cellulose fiber. The specific method comprises the following steps of uniformly mixing a flame retardant microcapsule wrapped by melamine resin with an aqueous solution of N-methylmorpholine oxide, heating and dissolving cellulose under reduced pressure, and finally carrying out spinning to obtain the fiber uniformly doped with the flame retardant microcapsule. The production process is short, the production process is environment-friendly, and continuous and stable production can be realized. The produced fiber is high in strength, soft in hand feeling, uniform in embedded microcapsule dispersion, washable and excellent in flame retardant property. 本发明属于纤维素材料领域，涉及一种阻燃纤维素纤维的制备方法。具体方法是将一种蜜胺树脂包裹的阻燃剂微胶囊与N-甲基吗啉氧化物水溶液均匀混合，加热减压溶解纤维素，最后经过纺丝后得到均匀掺杂阻燃剂微胶囊的纤维。本发明生产流程短，生产过程环保，可实现连续化稳定生产。生产的纤维强度高，手感柔软，嵌入微胶囊分散均匀耐水洗，阻燃性能优良。
