【摘要】 采用超声、DMAc、DMAc+KMnO4、甲醇+DMAc等四种不同的物理和化学方法对脱脂棉纤维进行预处理,并通过扫描电镜(SEM)及X射线衍射(XRD)等手段表征了处理前后脱脂棉纤维结构和形态的变化,其结构和形态随预处理方法的不同而发生不同变化.在这四种方法中以第三种DMAC+KMnO4预处理的处理效果较好.更多还原

【Abstract】 Absorbent cotton cellulose is pretreated by four kinds of techniques as ultrasonic wave,DMAc,DMAc+ KMnO4,Methanol+DMAc.The structure and configuration are investigated by SEM and XRD.Results show that after pretreated,the contents of cellulose decrease.The morphological structure changes with different pretreatments.Of four pretreatment techniques,DMAc+ KMnO4 is better for Absorbent cotton cellulose.更多还原
