摘　　要：采用Ca2+激活生物酶脱胶方法对苎麻纤维进行脱胶,测得脱胶后精干麻纤维的细度、断裂强力、断裂伸长、残胶率、白度等5项品质指标,并与传统的碱脱胶、复配生物酶脱胶结果进行比较;通过扫描电镜、红外光谱、X-衍射等测试手段对不同脱胶方法所得的精干麻纤维性能进行表征,研究结果表明:经Ca2+激活复配生物酶脱胶后的苎麻纤维表面光滑,光泽较好,纤维细度变细,强力增加,残胶率降低,纤维断裂伸长降低。To degum the ramie by use of Ca^2＋ activated complex biological enzyme and have the 5 quality indexes of fiber fineness, breaking strength, elongation at break, residual glue rate and whiteness of the degummed ramie measured and compared with that gained after traditional akali and complex enzyme degummed. And scanning electron microscopy, infrared spectroscopy and X - ray diffraction are used to test the degummed fiber. The result shows that the fiber degummed by Ca^2＋ activated compound enzyme is of surface smooth, better shiny, much finer, increased strength and low enlongation breaking and low plastic residue.
