    • PROBLEM TO BE SOLVED: To make an effective use of a bamboo material and reduce the quantity of industrial waste to improve residential environments by molding a bamboo fiber with a regenerated pulp of milk packs and a starch adhesive as a binder under pressure. SOLUTION: A bomboo fiber and regenerated pulp made of milk packs are mixed by stirring at a ratio of 8:2, and the mixture is molded with a starch adhesive as a binder under pressure. Further, the molding is pressurized for a specified time, and is heated at a low temperature under pressure in such a state that the surface is dry and a core contains moisture. In order to fibrillate a bamboo cut out is that the bamboo is battered and boiled in an about 5% sodium hydroxide solution to have its fiber softened. Next, the fiber is water- washed to separate protein and the sugar content, and is mixed by a blender to completely separate protein and sugar content. After that, the bamboo fiber is further water-washed, hermetically sealed in a vessel, and is stored in a dark place. About one week later, the fiber is made more flexible by a residual alkali content in boiling, so that the color shade of the fiber is made uniform.
