Abstract

The invention provides a technology for preparing bamboo fiber by 1, 4-butanediol in a solvent method, which comprises the steps of preparing bamboo into bamboo filaments; soaking the bamboo filaments in the solvent and heating to remove lignin, hemicellulose and other impurities on the surface of the cellulose; preparing into coarse bamboo fibre; beating the coarse bamboo fibre, washing with water simultaneously, and then spin-drying through a centrifuge; bleaching and cleaning; conducting mellowing to the bamboo fiber; soft-impressing the bamboo fiber; stowing fermentation and curing, and finally obtaining the bamboo fiber with spinnability after opening and carding. The solvent adopted by the invention has high boiling point and stable chemical property and can be recycled; the whole technological process does not generate black liquor and seriously pollute the environment, and belongs to clean techniques; the obtained natural bamboo fiber has the remarkable advantages of moisture absorption, quick dry, coolness, comfort, antibacterium, deodorization and the like; and the method has low cost and good economic benefit and environmental protection benefit.

Description

technical field

[0001] The invention belongs to the technical field of new materials for textiles, and more specifically relates to a solvent method for biologically preparing bamboo fibres. Background technique

[0002] The preparation of bamboo fiber has been reported in previous published patents, and the traditional method is to use caustic soda to cook to remove the lignin and hemicellulose of bamboo. Although the fiber is made to a certain extent, it is the same as paper pulping. Produce a large amount of black liquor, because black liquor is difficult to control, brings serious pollution to the environment. The present invention adopts solvent method to biologically prepare bamboo fiber, which can be recycled, and extracts lignin and hemicellulose from the used solvent, which reduces environmental problems. In the prior art, there is no biological preparation of bamboo fiber by solvent method. process method. Contents of the invention
