Abstract: The preparation process and stability of cellulose carbamate solution—a new spinning cellulose were studied.The results showed that the cellulose carbamate with content of N in the range of 2.34%-3.56% synthesized from cellulose pulp with polymerization degree ranging from 350 to 632 can be well dissolved in sodium hydroxide solution with the concentration 2.25 mol/L to 3.0 mol/L at-5-5℃,forming a cellulose carbamate solution with straw yellow.Through osmotic treatment,the solution can be directly used for spinning,for it lives up to the requirement that the weight ratio of cellulose carbamate to sodium hydroxide should be≥1,and has improved viscosity and stability.In addition,researches reveal that the urea、AlCl3 and ZnCl2facilitate the dissolving of cellulose carbamate.
