Manufacturing technique for preparing bamboo fiber by using biophysical technique

Abstract

The invention relates to a production process which adopts a biophysical technology to produce the bamboo fiber; the method comprises the following steps : breaking the joints in the bamboo and soak in the 1<#> biochemical treatment liquid and heating the liquid with steam, then soaking for two hours at the 70 DEG C under the atmospheric pressure; then obtaining the coarse bamboo fiber after opening and grading the fiber; then taking the coarse bamboo fiber as the raw material and soaking in the 2<#> biochemical treatment liquid, heating the liquid with steam, then soaking for 1-2 hours at the 60 DEG C under the atmospheric pressure, then drying, teasing and grading the fiber to obtain the fine bamboo fiber products. Both the 1<#> and 2<#> biochemical treatment liquid adopt the biochemical agent as the main ingredients, the composition of the biochemical agent includes 7.5-10.8% of TX-10; 7.5-8.3% of sulfonic acid; 5-6.9% of Peregal O; 6.5-9.2% of AE-S; 8.3-11.3% of 6501 and 53.5- 65.2% of wilted hay enzyme. The process has the advantages of low energy consumption, free pollution of wastewater and good fiber quality.

Description

The Production Technology of Bamboo Fibers Prepared by Biophysical Technology technical field The invention relates to a method for preparing plant fibers, in particular to a production process of using natural bamboo as a raw material to prepare bamboo raw fibers. Background technique Bamboo is known as the second largest forest resource in the world. The world's bamboo forest area is 22 million hectares. China is a country rich in bamboo resources, with a bamboo forest area of ​​5 million Km2, a stock of about 130 million tons, and an annual output of 8 million tons. The growth period of bamboo is half a year, and the forestation period is 2-3 years. After the bamboo is felled, new bamboo will naturally be produced. If the bamboo is not felled for a long time, the entire bamboo forest will die due to lack of ventilation. Therefore, rational felling and utilization of bamboo is beneficial to the growth of bamboo forests. Because bamboo grows fast, it is highly renewab...

Problems solved by technology

Disadvantages are large investment in disposable equipment, difficult technical operation, high power consumption, and easy carbonization of bamboo fibers during the production process, resulting in hard hand feeling

Its main disadvantage is that it produces more waste liquid, and the treatment of waste liquid is a big problem, otherwise it will seriously pollute the environment; secondly, due to the effect of high temperature and strong alkali, the mechanical strength of bamboo fiber decreases, which affects the use in the textile industry.
