Bamboo short fiber extraction technology

Abstract

The invention relates to the technical field of bamboo processing, in particular to a bamboo short fiber extraction technology. According to the specific scheme, the bamboo short fiber extraction technology comprises the steps that 1, bamboo joints of bamboo are removed, the bamboo is processed into bamboo pieces, and the bamboo pieces are washed clean; 2, the bamboo pieces are crushed into bamboostrips, and high-temperature high-pressure processing is carried out; 3, the bamboo strips obtained in step 2 are rolled to obtain bamboo cakes; and the bamboo cakes are put into a fiber splitting machine for carding to obtain crude fiber; 4, the crude fiber is cleaned and cut into segments; 5, fiber bundles obtained in step 4 are ground, washed and dried to obtain bamboo fiber. According to thebamboo short fiber extraction technology, the degumming effect of the bamboo fiber is improved, the quality of the bamboo fiber is improved, and the utilization rate of the bamboo is improved; moreover, the technology is convenient to operate, the extraction time is short, and no wastewater polluting the environment is generated.

Description

technical field [0001] The invention relates to the technical field of bamboo processing, in particular to a bamboo short fiber extraction technology. Background technique [0002] Cizhu is a plant widely planted in Southwest my country, and is widely used in the preparation of household bamboo products. It has the characteristics of softness, good toughness, and easy separation of bamboo green and bamboo yellow. Bamboo fiber refers to the fiber directly separated from bamboo using a unique process. Generally, according to the different spinning systems used by textile mills, the natural bamboo is sawn into the length required for production, and the lignin, hemicellulose, pectin and other impurities in the bamboo are removed by physical and chemical methods. Bamboo fibers are extracted directly from the [0003] In the prior art, though physical methods are used to extract raw bamboo fiber from Cizhu, although it is relatively environmentally friendly, it generally requi...

Problems solved by technology

[0003] In the prior art, though physical methods are used to extract raw bamboo fiber from Cizhu, although it is relatively environmentally friendly, it generally requires high temperature and high pressure, which not only requires high equipment, but also the quality of the extracted bamboo fiber is poor, and the hardness, fineness, uniformity, and strength of the fiber Such indicators cannot meet the requirements of textile fibers, and even cannot meet the requirements of preparing composite materials and non-woven materials; while the wastewater, waste residue, and waste gas produced by chemical methods will cause certain pollution to the environment, and the pollutants will be treated. In the process, not only the cost is high, but also the problem of difficult handling
