Description

Solvent method for biologically preparing bamboo fiber
Technical field
The invention belongs to weaving and use new material technology field, more specifically relate to a kind of solvent method for biologically preparing bamboo fiber.
Background technology
The preparation of bamboo fiber was still having report in the disclosed patent in the past, and traditional method is to adopt caustic soda to carry out the lignin and the hemicellulose of the process removal bamboo wood of boiling, though made fiber to a certain extent, but equally with paper-making pulping produced a large amount of black liquor, because of black liquor is difficult to administer, bring severe contamination to environment.The present invention adopts solvent method for biologically preparing bamboo fiber, can recycle, and extracts lignin and hemicellulose from spent solvent, has reduced the problem in the environmental protection, in the prior art as yet not relevant for process with solvent method for biologically preparing bamboo fiber.
Summary of the invention
The object of the invention provides a kind of technology for preparing bamboo fiber with solvent method; the boiling point height of the solvent that adopts, chemical property is stable, can recycle; whole technical process does not produce black liquor; not to the environment structure severe contamination, belong to cleaning and give birth to process, obtain natural bamboo fiber; has hydroscopic fast-drying; cool and comfortable and antibacterial and deodouring etc. are significantly a bit, and be with low cost, has good economic benefits and environmental protection benefit.
Solvent method for biologically preparing bamboo fiber of the present invention is characterized in that: the preparation process of described method is:
(1) bamboo prepares the well-thought-out plan silk;
(2) with the bamboo silk through the immersion of solvent, the lignin that adds the heat abstraction cellulose surface, hemicellulose and other impurity; Preparation well-thought-out plan crude fibre
(3) the bamboo crude fibre is beaten water flushing simultaneously, centrifuge dries;
(4) bleaching clean;
(5) bamboo fibre is carried out soft treatment;
(6) with the soft pressure of bamboo fibre;
(7) heap storage fermentation health, the bamboo fiber that can obtain to have spinnability after the shredding combing.
Of the present inventionly be significantly a little: the solvent boiling point height that the present invention adopts, chemical property is stable, can recycle, whole technical process does not produce black liquor, to the environment structure severe contamination, does not belong to process for cleanly preparing.Make bamboo fiber and kept its physical characteristic, the surface still have countless fine grooves, in have cavity, edge crackle is arranged, just as capillary, can between Shun, absorb and evaporate moisture content, moisture absorption, lead wet and permeability occupies first of each fiber, has good deodorization, an anti-ultraviolet function.Can effectively suppress staphylococcus aureus, Candida albicans, Escherichia coli etc., antibiotic rate height.Higher, the good springiness of bamboo fiber intensity, its fabric have good wear resistance, drapability and gas permeability in addition, and good dyeability, bamboo fiber by pure spin or blending after can be used for producing underwear, nightwear, T-shirt, undershirt, gym outfit, socks, infant's clothes etc.Woven fabric is produced jacket, Casual Wear, Western-style clothes suit, shirt, one-piece dress, bedding and towel, bath towel etc.Bamboo fiber also can be used for producing new material products such as foot pad, summer sleeping mat, sofa cloth, carpet, gauze, mouth mask in addition, new technology can be utilized mao bamboon or bamboo kinds such as green bamboo and China pink, high boiling solvent (hbs) is recyclable to be recycled, and has good economic benefit and social benefit.
