Dry pressing method for bamboo fabric

Abstract

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
【課題】竹材を有効利用する。 【解決手段】竹材を生竹状態で解繊して粉・粒状でない長い繊維部を得て熱プレスにより竹シート(竹圧紙)を作成際に、水分を乾燥によって調整せずに熱プレスできるようにする。この時シートの表裏に熱による焦げ、水蒸気が関係する染み、膨れ(結合不良)を発生させないようにする。竹繊維物に20数%も含まれる糖類の影響を押さえるために類似物である吸湿性のある澱粉を重量比で2%程度添加する。または吸湿により粘性を発揮するポリビニールアルコール微粉末を結合材として添加する。 【選択図】図2
