新型纤维素甲酸酯丝线的制备及其性能研究
Preparation and Properties of Novel Cellulose Formate Threads
摘要
Abstract
In this study,cellulose formate(CF)was prepared by the reaction of cellulose with formic acid,and a novel CF thread was pro-duced by wet spinning using the formic acid solution of CF.When the reaction temperature was 50℃and the reaction time was 5 h,the for-mic acid solution of CF was passed through two-stage coagulation baths of 1％NaOH mass ratio and of 5％ZnSO4 mass ratio,respectively,followed by washing and drying,obtaining the CF threads with uniform morphology,high strength(tensile strength of 151 MPa),excellent thermal stability(initial thermal decomposition temperature of 252℃)and water stability(showed no morphological change after being im-mersed in water for 3 months).CF threads had higher tensile strength than some reported nanocellulose,bacterial cellulose,and oxidized re-generated cellulose based threads.关键词
