摘　　要：研究了香蕉纤维的碱法脱胶工艺。在分析碱剂用量、亚硫酸钠用量、多聚磷酸钠用量、脱胶温度和时间等单因素影响香蕉纤维脱胶效果的基础上,通过正交实验确定香蕉纤维碱法脱胶的优化工艺:碱剂1.5 g/L,多聚磷酸钠2.5 g/L,亚硫酸钠2.0 g/L,85℃脱胶70 min。脱胶后香蕉纤维的白度为25.79%,断裂强度为21.03 cN/dtex,失重率为15.62%,满足纤维可纺性要求。The alkaline degumming process to banana fibers was studied.On the basis of studying the effect of alkaline agent dosage,sodium sulfite consumption,sodium polyphosphate concentration,scouring temperature and time on degumming performance,the optimal degumming technology was determined via orthogonal experiments.The optimum degumming processes were as follows:sodium carbonate 1.5 g/L,polyphosphate sodium 2.5 g/L,sodium sulfite 2.0 g/L,scouring at 85℃for 70 min.The results indicated that the whiteness of the banana fiber was 25.79%,breaking tenacity was 21.03 cN/dtex,and the weight loss ratio was 15.62%.All indexes meet the requirements of fiber spinnability.
