ABSTRACT:
A method for degumming decorticated plant bast fiber, such as ramie flax, or hemp 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 between about 10 to 20 minutes to degum the plant fiber. The treatment solution is maintained at an elevated temperature in the range between about 60.degree. C. and 65.degree. C. and has a pH between about 2.0 and 3.5.
