Characterization of Degummed Ramie Fibre (Variety R-1449)

ABSTRACT

Decorticated ramie fiber (Variety R-1449) was degummed using different systems, namely, individual alkali, mix alkali, enzyme, mix enzyme, and peracetic acid to the optimal level of residual gum content. Further, the optimal degummed samples of various systems have been characterized through IR analysis, DSC thermographs, scanning electron microscopes, tensile properties etc. The chemical constituents of degummed samples of various systems at optimal level along with untreated decorticated ramie fiber have been determined and compared. Study suggests the use of new eco-friendly peracetic acid is best degumming method for decorticated ramie followed by synergetic effect of alkalis.

摘要

脱皮苎麻纤维 (品种R-1449) 采用不同体系脱胶, 即单独碱、混合碱、酶、混合酶和过氧乙酸, 以达到最佳残留胶含量. 此外, 通过红外分析、DSC热像图、扫描电子显微镜、拉伸性能等对各种体系的最佳脱胶样品进行了表征. 测定并比较了不同体系最佳脱胶样品和未经脱皮处理的苎麻纤维的化学成分. 研究表明, 新型环保过氧乙酸是脱皮苎麻的最佳脱胶方法, 其次是碱的协同作用.
