    • PROBLEM TO BE SOLVED: To provide a carbonization raw sheet using vegetable fibers for easily producing a carbonized sheet at low cost; and to provide a method and apparatus for producing the same.SOLUTION: In a carbonization raw sheet A, a vegetable fiber layer 1 is used as a core layer, and vegetable-based regenerated fiber layers 2, 2 are stacked on both of the front and back surfaces of the vegetable fiber layer. The vegetable fiber layer 1 and the vegetable-based regenerated fiber layers 2, 2 on both of the front and back surfaces are fixed to each other by entanglement using part of vegetable-based regenerated fibers 2a in each vegetable-based regenerated fiber layer 2. The vegetable fiber layer 1 and the vegetable-based regenerated fiber layers 2, 2 are entangled without using an adhesive or heat-fusible fibers, so that binding force between fibers is not lost even by baking. As a result, carbonized products D1 and D2 can be obtained only by baking, so that production is simplified, and production cost can be reduced. The obtained carbonized products D1 and D2 can exhibit antibacterial and deodorizing performance, electromagnetic wave shielding performance, and far-infrared radiation performance.
    • 要解决的问题:提供一种使用植物纤维以低成本容易地生产碳化片材的碳化原料片; 并提供其制造方法和装置。解决方案:在碳化原料片A中,植物纤维层1用作核心层,植物性再生纤维层2,2堆叠在前面 和植物纤维层的背面。 通过使用植物性再生纤维层2中的植物性再生纤维2a的一部分,通过缠结将植物纤维层1和前后表面的植物性再生纤维层2,2彼此固定。 植物纤维层1和植物性再生纤维层2,2在不使用粘合剂或热熔纤维的情况下缠结,因此即使进行烘烤也不会损失纤维之间的结合力。 结果,碳化物D1和D2只能通过烘烤获得,从而简化了生产,并且可以降低生产成本。 获得的碳化产物D1和D2可以表现出抗菌除臭性能,电磁波屏蔽性能和远红外辐射性能。
