摘　　要：探讨碱处理对竹浆纤维微观结构的影响规律。通过对竹浆纤维和普通粘胶纤维分别采用浓度为15 g/L、30 g/L、45 g/L、60 g/L、75 g/L、90 g/L、120 g/L、150 g/L、180 g/L、210 g/L、240 g/L的NaOH溶液进行处理,对比分析了不同浓度碱处理对两种纤维形态结构和结晶结构的影响。结果表明:碱处理对竹浆纤维和普通粘胶纤维的作用相似;在较低浓度时,碱处理使纤维截面中出现孔隙,经碱处理纤维的结晶度得到了提高。Effect rules of alkali treatment on bamboo fiber microstructure were discussed. Bamboo fiber and common viscose were treated in NaOH of 15 g/L,30 g/L,45 g/L,60 g/L,75 g/L,90 g/L,120 g/L,150 g/L,180 g/L,210 g/L and 240 g/L. Effeet of different concentration treatment on the two fiber morphologies and erystal structures were eontrasted and analyzed. The result shows that effect of alkali treatment on bamboo fiber and eommon viscose is similar. When the eoncentration is lower, void would be appeared in fiber cross section after alkali treatment, fiber crystallinity would be increased after alkali treatment.
