摘要(Abstract)：
纤维素浆粕活化工艺的主要目的是打开纤维素的结晶区,利于溶剂进入。介绍了Lyocell活化工艺的原理及重要性,活化工艺控制参数为:选用纤维素活化酶,其与纤维素质量比为0.003~0.006,活化p H值5~6,活化温度40~60℃,活化时间40~60 min,活化终止p H值10~13。经过活化工艺,纤维素聚合度略有降低,浆液过滤指数好,浆粕的选型范围更宽,有利于产品品种的开发。
The main purpose of the activation process is to open the crystalline region of cellulose, it is favor-able for solvent in the cellulose. The principle and importance of Lyocell activation process are introduced.The activation process parameters as follows: enzyme is cellulose enzyme, enzyme and cellulose weight ratiois 0.003~0.006, activation p H value is 5~6, activation temperature is 40~60 ℃, the activation time is 40~60 min, activated terminated p H value is 10~13. After activation process, cellulose DP is reduced less,dope filtration index is well, pulp selection range is wider, and it is benefit for the product variety develop-ment.
