A kind of method for extracting bamboo fiber from bamboo layers

Abstract

The invention provides a method for extracting bamboo fibers from bamboo by layering. Bamboo materials are classified and selected, sliced ​​and layered into bamboo strips with green bamboo layer, bamboo strips with bamboo flesh layer and bamboo strips with bamboo yellow layer, and then the length-fixed bamboo strips are sequentially carried out. The strips are softened and continuously rolled to obtain the thick bamboo fibers of the bamboo green layer and the thick bamboo fibers of the bamboo flesh layer; the thick bamboo fibers of the bamboo green layer are sequentially steamed and degummed, bleached, pickled, dried, emulsified oil is added for health preservation and The mechanical carding process is used to obtain bamboo fibers for textiles; the thick bamboo fibers in the bamboo flesh layer are sequentially subjected to the processes of adding emulsified oil for health, mechanical carding and fiber cutting processes to obtain general-purpose bamboo fibers. The invention can simultaneously obtain the bamboo fiber for textile use and the bamboo fiber for general use, and effectively improves the utilization rate of the bamboo material.

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] 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. [0005] Extracting bamboo fiber from bamboo is a current research hotspot and the future development trend of bamboo indust...

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
