Abstract
A process of decortication for separating the bast from the inner core of fibre plants using a disc refiner includes the steps of cutting the straw to a predetermined length; refining the straw by passing the cut straw of the predetermined length through a disc refiner with an applied energy less than about 150 kWh/t; and screening the refined straw to separate the bast fibres from the inner core.
Claims13
A method of producing bast fibres by processing the straw of a plant having a bast layer and an inner core, said method comprising the steps of:
- a. cutting the straw to a predetermined length;
- b. refining the straw by passing the cut straw of the predetermined length through a disc refiner with an applied energy less than about 150 kWh/t;
- and
- c. screening the refined straw to separate the refined straw into specific fractions comprising clean bast fibres, crude bast fibres, crude inner core, and dust.
A method of producing bast fibres by processing the straw of a plant having a bast layer and an inner core, said method comprising the steps of:
- a. cutting the straw to a predetermined length;
- b. dry refining the straw by passing the cut straw of the predetermined length through a disc refiner with an applied energy less than about 150 kWh/t;
- and
- c. screening the refined straw to separate the bast fibres from the inner core.
