A method for degumming decorticated plant bast fiber such as ramie bast fiber, to remove pectin-containing material therefrom. The decorticated plant bast fiber is washed with a washing solution containing a surface active agent to penetrate the plant bast fiber to remove water soluble material therefrom. The washed plant bast fiber is then rinsed. The washed and rinsed plant bast fiber is treated with an aqueous, acidic treatment solution of fungal pectinase for a period of time up to about one hour to degum the plant fiber. The treatment solution is maintained at an elevated temperature and has a pH between about 2.0 and about 4.5.
