Bamboo Fiber Sheet

Abstract

The present invention relates to a bamboo fiber sheet. The bamboo fiber sheet is provided with filamentous bamboo fibers (7) and pulp bamboo fibers (8), wherein the filamentous bamboo fibers have a fiber thickness of over 0.3 mm in the bamboo fibers split from bamboos and have vascular bundles containing the outer skin side; and the pulp bamboo fibers have a fiber thickness of lower than 0.3 mm in the bamboo fibers and have vascular bundles containing the inner skin side. The filamentous bamboo fibers (7) and the pulp bamboo fibers (8) are integrally mixed. With adoption of the bamboo fiber sheet provided by the utility model, no matter what the degree of fragmentation of the bamboo fibers is, the strength and rigidity of the bamboo fiber sheet can be raised.

Description

technical field [0001] The invention relates to a bamboo fiber sheet made by taking bamboo fiber as a raw material. Background technique [0002] Conventionally, bamboo fiber is known as a plant fiber material instead of wood. Among non-wood plant fibers, bamboo fiber has higher specific strength and has excellent material properties. In addition, since bamboo grows faster than wood, it is also advantageous in terms of productivity. Therefore, technologies for applying bamboo fibers to various products such as vehicle interior materials, building materials, and acoustic materials have been developed. [0003] Patent Document 1 describes a nonwoven fabric containing heat-sealable composite fibers made of a thermoplastic resin and bamboo fibers. In this technique, after laminating bamboo fiber and heat-sealable composite fiber, it heat-processes and manufactures a bamboo fiber sheet. The heat-fusible composite fiber is softened and melted by heat treatment, and functions a...

Problems solved by technology

However, in this case, compared with the case where glass fibers and resin fibers are used together, it is difficult to secure sufficient strength and rigidity.
