Characterization of Degummed Ramie Fibre (Variety R-1449).

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. [ABSTRACT FROM AUTHOR]
