PROBLEM TO BE SOLVED: To provide an ecological dry pressing method for a bamboo fabric which uses a fabric manufactured not by a conventional wet paper making method using a pulp liquid but by a dry fabric processing method producing no waste liquid in a fabric processing process, and does not use water. SOLUTION: When a raw bamboo material is defibrated to obtain a long fiber part which is not powdery nor granular, and the fiber part is hot-pressed to make a bamboo sheet (bamboo press paper), the fiber part can be hot-pressed without adjusting moisture by drying. The occurrence of a burn by heat, a stain related to water vapor, and a blister (defective bonding) on the surface and back of the sheet is prevented. Hygroscopic starch, which is a similar substance to saccharides, about 2% in weight ratio is added in order to avoid the influence of saccharides contained as much as 20% in the bamboo fabric. Alternatively, the fine powder of polyvinyl alcohol which demonstrates viscosity by moisture absorption is added as a bonding agent. COPYRIGHT: (C)2005,JPO&NCIPI
