Abstract
The present invention relates to a pressure-formed bamboo sheets or bars composed of bamboo materials having a reduced variation in fiber density. A bamboo is split in the peripheral direction into a plurality of long bamboo slices, then the long bamboo slices are subjected to heat mothproofing. The heat-mothproofed bamboo slices are separated under pressure into a plurality of extra-fine bamboo slivers and are coated with resin until one complete bamboo sheet or bar is obtained.
Claims15
A method of shaping bamboo fibers, comprising the steps of:
- splitting bamboo rods along an axial direction thereof to obtain a plurality of divisional bamboo pieces;
- heat treating the divisional bamboo pieces in a manner sufficient to exterminate insect eggs in the divisional bamboo pieces;
- applying mechanical pressure to the divisional bamboo pieces in a direction transverse to an axial direction of the divisional bamboo pieces to obtain a plurality of bamboo slivers;
- applying an adhesive to the plurality of bamboo slivers;
- and
- shaping the plurality of bamboo slivers having the adhesive applied thereto in a form.
