Problems solved by technology

This method can hydrolyze the hemicellulose in the bamboo fiber, the lignin is softened, the fiber yield is high, no chemicals are needed, no pollution, and the fiber uniformity is better, but the fiber treatment process is complicated, the fiber is thicker, and the fiber size is difficult to control. High equipment cost, darker fiber color, generally brown

Abstract

The invention provides a method for preparing bundle-shaped bamboo fiber separated by breaking the wall. The method comprises: cutting moso bamboo, removing knots, processing into bamboo strips, removing internal bamboo yellow, and cutting into sections to obtain bamboo chips, After soaking in the alkaline salt solution, use the pulsating vacuum pressure steam method to alternately evacuate and high-pressure hot steam, and then perform three-stage roller rolling to obtain loose bamboo chips. Filter, wash with water, sort and dry to obtain bundle-shaped bamboo fibers separated by wall breaking. The invention can realize integrated processing of high-performance bamboo fiber bundles, and the prepared bundle-shaped bamboo fibers have uniform fineness, long length, large aspect ratio, excellent breaking strength and tensile strength.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a method for preparing bundle-shaped bamboo fibers separated by breaking walls. Background technique [0002] Bamboo fiber comes from bamboo vascular bundles, and the vascular bundles are scattered in the parenchyma of the bamboo wall, which is a complex of conductive tissue and mechanical tissue. The average tensile strength of the lateral vascular bundles of bamboo bamboo can reach 648.03MPa. The bundled fibers that make up the vascular bundles are high toughness materials with an average tensile strength of 729.25MPa, while the parenchyma is a honeycomb high brittle material with an average tensile strength of 40.02MPa. In terms of chemical components, the content of cellulose in bamboo vascular bundles was higher, and the content of hemicellulose in parenchyma was higher. [0003] At present, the research on the preparation method of bamboo fiber mainl...
