Embodiment 1

[0011] A kind of bamboo fiber processing technology, according to the following steps: (1) pretreatment: moso bamboo is cut off, scrapes off green bark, grinds along fiber direction; % Ca(OH) 2 Solution, the Phyllostachys pubescens after the pretreatment is dropped into the pretreatment pond, also adds the NaOH of 0.01%, the (Na) of 0.01% in the pretreatment pond 2 CO 3 , and 0.001% NaHCO 3 soaked in the solution for 30 days; remove the non-fibrous components in moso bamboo to obtain preliminary bamboo fibers; (3) put the soaked preliminary bamboo fibers into the washing tank to rinse, scrape off impurities, and obtain pure bamboo fibers bamboo fiber.

Embodiment 2

[0013] A kind of bamboo fiber processing technology, according to the following steps: (1) pretreatment: moso bamboo is cut off, scrapes off green bark, grinds along fiber direction; % Ca(OH) 2 Solution, the Phyllostachys pubescens after the pretreatment is dropped into the pretreatment pond, also adds the NaOH of 0.05%, the (Na) of 0.05% in the pretreatment pond 2 CO 3 , and 0.03% NaHCO 3 soaked in the solution for 10 days; remove non-fibrous components in moso bamboo to obtain preliminary bamboo fiber; (3) put the soaked preliminary bamboo fiber into the washing tank and rinse it clean, scrape off impurities, and obtain pure bamboo fiber bamboo fiber.

Embodiment 3

[0015] A kind of bamboo fiber processing technology, according to the following steps: (1) pretreatment: moso bamboo is cut off, scrapes off green bark, grinds along fiber direction; % Ca(OH) 2 Solution, the Phyllostachys pubescens after the pretreatment is dropped into the pretreatment pond, also adds the NaOH of 0.03%, the (Na) of 0.02% in the pretreatment pond 2 CO 3 , and 0.015% NaHCO 3 soaked in the solution for 13 days; remove the non-fibrous components of moso bamboo to obtain preliminary bamboo fibers; (3) put the soaked preliminary bamboo fibers into the washing tank to rinse, scrape off impurities, and obtain pure bamboo fiber.

Abstract

The present invention relates to the technological scheme of treating bamboo fiber. The treating process of bamboo fiber includes the following steps: pre-treating via cutting bamboo, scraping out green skin and rolling; soaking the pre-treated bamboo in pre-treatment pond with Ca(OH)2 solution of 5-10 wt% concentration for 10-30 days to obtain coarse bamboo fiber; and flushing in the flushing pond to eliminate impurity and obtain pure bamboo fiber. The present invention features that additive mixture comprising NaOH, Na2CO3 and NaHCO3 is added into pre-treatment pond. The present invention has the advantages of less investment, low cost, fast effect, cheap processing solution of Ca(OH)2 and small amount of additive, short processing period and raised mechanical performance of bamboo fiber.

Description

technical field [0001] The invention relates to a bamboo fiber processing technology, in particular to a bamboo fiber processing technology with less investment. Background technique [0002] At present, with the development of science and technology, bamboo fiber can be widely used. However, the existing processing technology of bamboo fiber is relatively complicated, usually requires heating, complicated equipment, and large one-time capital investment, which is not suitable for the needs of deep processing of moso bamboo in vast rural areas and mountainous bamboo production areas. Contents of the invention [0003] The purpose of the present invention is to provide a kind of bamboo fiber processing technology that input is little, cost is low, does not need heating. The tensile strength and other mechanical properties of the bamboo fiber obtained by the processing technology are better. [0004] Technical scheme of the present invention is: [0005] A kind of bamboo ...
