Abstract
A method, application and device for obtaining fibres from at least one plant stem or from plant bast is disclosed. The at least one plant stem is treated with at least one high-speed liquid jet or high-speed gas jet. At the start of treatment with the high-speed liquid jet or the high speed gas jet the at least one plant stem has a moisture content of at least 25% and/or vegetable glues, in particular the pectin and hemicelluloses, of the plant stem are in a swollen state.

A method for obtaining plant fibers from at least one plant stem or from at least one unit of plant bast separated from wood, with or without cuticula, comprising steps of:
- breaking down the plant stem or the unit of plant bast, with or without cuticula, through treatment with at least one high-speed liquid jet or high-speed gas jet, and wherein the at least one plant stem or the at least one unit comprising plant bast, with or without cuticula, has a moisture content of at least 25%, or vegetable glues of the plant stem or the unit of plant bast are in a swollen state at a start of the treatment with the high-speed liquid jet or high-speed gas jet.
An application of at least one high-speed liquid jet or high-speed gas jet for obtaining plant fibers from at least one plant stem or from at least one unit of plant bast separated from wood, with or without cuticula, wherein the plant stem or the unit of plant bast, with or without cuticula, is broken down through treatment with the at least one high-speed liquid jet or high-speed gas jet, and the at least one plant stem or the at least one unit comprising plant bast, with or without cuticula, has a moisture content of at least 25%, or vegetable glues of the plant stem or the unit of plant bast are in a swollen state before starting the treatment with the high-speed liquid jet or high-speed gas jet.
A device for obtaining plant fibers from at least one plant stem or from at least one unit of plant bast separated from wood, with or without cuticula, comprising:
- a retention or guide element for at least one plant stem or at least one unit comprising plant bast separated from wood, with or without cuticula;
- and
- a device for treating the at least one plant stem or unit comprising plant bast separated from wood received in the retention or guide element with at least one high-speed liquid jet or high-speed gas jet.
