Method for extracting bamboo fibers from bamboo in layering mode

Abstract

The invention provides a method for extracting bamboo fibers from bamboo in a layering mode. The method comprises the steps that bamboo materials are classified, selected, sliced and layered into bamboo outside layer bamboo canes, bamboo middle layer bamboo canes and bamboo inner skin layer bamboo canes, and then fixed-length bamboo cane softening and continuous rolling splitting are carried out in sequence to obtain crude bamboo fibers of the bamboo outside layer and crude bamboo fibers of the bamboo inside layer; the procedures of stewing and degumming, bleaching, acid pickling, drying, emulsified oil adding for maintenance and mechanical carding are carried out on the crude bamboo fibers of the bamboo outside layer in sequence, and the bamboo fibers for spinning are obtained; the procedures of emulsified oil adding for maintenance, mechanical carding and fiber cutting off are carried out on the crude bamboo fibers of the bamboo inside layer in sequence, and the bamboo fibers for a general purpose are obtained. The bamboo fibers for spinning and the bamboo fibers for the general purpose can be obtained at the same time, and the utilization rate of the bamboo materials is effectively increased.

Description

【Technical field】 [0001] The invention relates to a treatment process in the field of bamboo processing, in particular to a method for extracting bamboo fibers from bamboo layers. 【Background technique】 [0002] Bamboo raw fiber is also known as primary bamboo fiber. It is a fiber directly processed from bamboo by mechanical, physical, biochemical and other methods. It has been used in construction materials, automobile manufacturing, sewage treatment, daily products and other industries. It also has extremely important application prospects. Some scientific research institutes and enterprises at home and abroad have carried out the research and development of bamboo fiber. Japan was the earliest in 1994 by ASK Co., Ltd., and Sanshin Heating Industry Co., Ltd. (Kanagawa Prefecture, Japan) proposed the production method of bamboo fiber. [0003] Extracting bamboo fiber from bamboo is a current research hotspot and the future development trend of bamboo industry. But up to ...

AI Technical Summary

Problems solved by technology

The main problem of the current mechanical processing method is that the structural characteristics of bamboo fiber distribution are not considered, and the whole bamboo or bamboo segments are directly processed. Although the processing technology in the early stage is relatively simple, the quality of the extracted crude fibers is different, making subsequent fiber post-processing difficult. Increased, the technical performance index of the extracted refined fiber is low, and important technical indexes such as fiber fineness, strength and uniformity are difficult to meet the product requirements

This processing technology divides the bamboo material into pieces according to bamboo green and bamboo yellow, and the prepared bamboo fiber can have better quality than the traditional process, but the prepared bamboo fiber is single and has the problem that the quality is not ideal, especially it cannot Solve the problem of fiber uniformity
