摘　　要：研究了制备纤维素纤维的新型原料——纤维素氨基甲酸酯（CC）溶液的制备工艺及其稳定性。结果表明：在-5～10℃条件下,用聚合度为350～612的纤维素浆粕（棉浆粕、木浆粕）合成的氮含量（酯化度）为2.34%～3.56%的CC能很好地溶解在质量百分比浓度为8%～11%的NaOH溶液中,形成淡黄色透明溶液,该溶液稳定性良好,可用于纺丝。另外,尿素、AlCl3及ZnCl2在一定范围内对CC有助溶作用。The preparation and stability of cellulose carbamate solution by dissolving cellulose carbamate——a new spinning cellulose were studied. The results showed that the cellulose carbamate which synthesized with cellulose pulp that polymerization degree was in the range of 350～612 and the content of N in the range of 2.34 %～3.56 % could be dissolved in sodium hydroxide solution of 8 % to 11% at temperatures of -5～10 ℃ form 7 % cellulose carbamate solution with straw yellow. The obtained solution could be directly used for spinning. The urea、AlCl3 and ZnCl2 would help to dissolving in a given range.
