Abstract
Bamboo fibers are utilized to serve as a reinforcing material and for manufacturing an inorganic molded body. In order to produce the bamboo fibers with excellent durability, in a first step bamboo material is compressed to be roughly crushed and in a second step the roughly crushed bamboo material is fiberized using a grinding machine. The moisture content of the bamboo material subjected to the first step is set to be more than 65%. After the completion of at least one of the first and second steps a drying step is taken so that the moisture content of the bamboo material is adjusted to within the range of 3 to 35%.
Claims19
A method of producing reinforcing bamboo fibers, comprising:
- (1) compressing a bamboo material having a moisture content above 65% to roughly crush it;
- (2) fiberizing the roughly crushed bamboo material using a grinding machine to form bamboo fibers of said bamboo material;
- and
- (3) after the completion of at least one of said step (1) and said step (2), drying said bamboo material to a moisture content within the range of 3 to 35%, whereby said reinforcing bamboo fibers are formed, wherein moisture content is defined as ((water-containing weight-dry weight)/dry weight).times.100.
A method of producing reinforcing bamboo fibers, comprising:
- (1) compressing a bamboo material having an inner thin skin portion and having a moisture content above 65% to roughly crush it;
- (2) fiberizing the roughly crushed bamboo material using a grinding machine to form bamboo fibers of said bamboo material;
- (3) removing the inner skin portion of said bamboo material by mechanical separation;
- and
- (4) after the completion of at least one of said step (1) said step (2) and said step (3), drying said bamboo material to a moisture content within the range of 3 to 35%, whereby said reinforcing bamboo fibers are formed wherein moisture content is defined as ((water-containing weight-dry weight)/dry weight).times.100.
A method of producing reinforcing bamboo fibers, comprising:
- (1) compressing a bamboo material having an inner thin skin portion and having a moisture content above 65% to roughly crush it;
- (2) fiberizing the roughly crushed bamboo material using a grinding machine to form bamboo fibers of said bamboo material;
- (3) removing the inner thin skin portion of said bamboo material by water-immersion separation;
- (4) after the completion of at least one of said step (1) and said step (2), drying said bamboo material to a moisture content within the range of 3 to 35%, whereby said reinforcing bamboo fibers are formed, wherein moisture content is defined as ((water-containing weight-dry weight)/dry weight).times.100.
