Process and apparatus for obtaining natural fibres, in particular bamboo fibres, for use as a reinforcing material

摘要

The present invention relates to the field of extraction and processing of natural fibers from fibrous natural thus renewable raw materials, especially from bamboo materials to be useful as reinforcing materials in the currently most commonly used matrix materials. It is the technical problem of the invention seeks to provide a method and an arrangement which causes the holistic technical solution a comminution of the feed material along the structure boundaries with a high proportion of ingredients in the length / diameter ratio of 100 in Austragungsgut. According to the invention the technical problem is solved in that any desired pre-comminuted in flowability, fibrous organic materials, but in particular of bamboo, a single- and / or multi-stage treatment process, consisting of a washing step, a Druckbedampfung or shiftable wash, a grinding process and a downstream classification stage, are subjected. Are obtained as a finished product depending on the procedure and conditions fibers _F l ≤60 mm, or example, _F d ≤1-2 mm. There are both wet-dry as exclusively dry type method sequences provided.
