Influence of pre-treatment on enzymatic degumming of apocynum venetum bast fibers in supercritical carbon dioxide

Pre-treatment of apocynum venetum bast fibers in supercritical carbon dioxide can improve the efficiency of enzymatic degumming of apocynum venetum bast fiber. This paper studies experimentally effect of pressure and degumming time on degradation rate, the results can be used for optimal design of degumming.
