Bast-fiber material processing method

A method of processing unscutched bast-fiber materials, comprising a woody part, cellulose, and encrusting substances, so as to elicit elementary fibers, comprising, in sequence, steps of:

• a. feeding raw materials comprising intermediate products of bast-fiber materials after biological enzyme treatment without subsequent mechanical scutching into a bale-breaker with a loosener;
• b. feeding the raw materials from said bale breaker with the loosener into a metering system;
• c. biochemically treating the raw materials;
• d. generating pulsed electric discharges between two electrodes disposed within a chamber containing a liquid medium and the biochemically treated raw materials so as to effectively generate enhanced hydraulic pressures and mechanical actions within the liquid medium, including shock waves and cavitation, which will tend to separate bast-fiber products from the raw materials, wherein said enhanced hydraulic pressures and mechanical actions result in generation of a discharge channel which expands at a rate of over 100 m/s and processing the biochemically treated raw materials in the chamber;
• e. rinsing the bast-fiber products with emulsifying reagents;
• and
• f. washing and pressing the bast-fiber products followed by loosening, final drying and fine loosening so as to obtain elementary fibers which retain the length, diameter and ordered crystalline structure of the cellulose in the bast-fiber material.
