The operation of the method is very simple, the equipment can be obtained by slightly improving the conventional wet process spinning equipment, and the cost is low. The used raw material bamboo has the characteristics of large output, easy availability, and low cost. The provided functional bamboo fiber has the antibacterial and healthcare effect, can absorb and maintain the moisture, and releases the drug effect sustainably.
Description
Technical field
The invention belongs to the deep processing and utilization field of agriculture and forestry product, particularly relate to one and utilize ionic liquid
for solventproduce after process bamboo powder and there is Chinese medicine that is antibacterial, health care
functionalthe method of bamboo fibre.
Background technology
Bamboo, as a kind of natural reproducible resource of abundance, has that growth is fast, output is high, strong to carbon dioxide absorption ability, can slow down features such as " greenhouse effects ".The bamboo fibre simultaneously extracted from bamboo has certain moisture absorption hydrofuge, antibacterial row, biodegradable row and biocompatibility etc.Current China bamboo germ plasm resource, bamboo grove area, accumulation and output all occupy first place in the world, also there is flourish trend in the domestic exploitation for bamboo at present, as various bamboo wood sheet material, bamboo commodity, bamboo carbon, bamboo pulp and the nearest bamboo fibre fabric etc. occurred.But it is not high that these all also exist producing level to the utilization of bamboo, the feature that added value of product is lower.Comprised the method for the method, mechanochemistry combination method and the chemistry that utilize physical mechanical at present with the technique producing textiles by bamboo extraction bamboo fibre.The bamboo fibre that physical mechanical processing method and mechanochemistry combination method obtain containing lignin and colloid more, general restriction that is comparatively thick and stiff or bamboo fibre filament length is generally used for coarse average family daily necessities and makes or handicraft knitting, the bamboo fibre that the textiles for clothes processing then mainly utilizes the method for chemistry obtained.Make the solvent chemically producing bamboo fibre be generally adopt to produce the dissolving of viscose or the solvent of sky silk at present, it has certain defect in environmental requirement.
Ionic liquid is a kind of environmental protection solution being in recent years newly widely used in Green Chemistry field, its distinctive good solvent, non-volatile, to advantages such as water and air are stable, particularly its good good solvent, is widely used for the green replace solvents as volatile organic solvent.Ionic liquid is found dissolved cellulose, utilize bamboo to be dissolved in ionic liquid and form homogeneous phase solution, then Chinese medicine is added wherein, form Chinese medicine and be partly dissolved the not molten state of part, then form a kind of functional fiber element with Chinese medicinal health-care function by the method for wet spinning.
Summary of the invention
What the technical problem that the present invention solves was the pure homogeneous phase of acquisition of the characteristics among new solvents of cellulose operability utilizing a kind of environmental protection can spinning bamboo fibre solution, then mixes with certain Chinese medicine and generate a kind of Chinese medicine with special efficacy
functionalbamboo fibre.
Object of the present invention is achieved through the following technical solutions: a kind of method producing Chinese medicine regenerated bamboo fiber, it is characterized in that comprising following operating procedure:
(1) by after bamboo pulverizing, filtration, filter and dewater, then carry out after activation processing through sodium hydroxide solution after being soaked in water, by deionized water rinsing pH value to 7, filter, vacuumize, obtains pretreated bamboo powder;
(2) in the pretreated bamboo powder of step (1) gained, ionic liquid 1-butyl-3-methyl imidazolium villaumite is added, heating-up temperature to 80 DEG C, after insulation 2 ~ 5min, add dimethyl sulfoxide (DMSO) (DMSO) while stirring, after carrying out solubilizing reaction, centrifugal filtration, obtains bamboo powder ionic liquid solution;
(3), in Chinese medicine being pulverized, joining bamboo powder ionic liquid solution that step (2) prepares after drying, carry out stirring, deaeration, according to technique spray silk, the traction of wet spinning, qualitatively obtain Chinese medicine Functiaonl bamboo fiber.
Hinge structure of the present invention, has following advantage and beneficial effect: present invention employs a kind of novel efficient and environment-friendly type solvent and dissolve bamboo wood, then mixes with ultra-fine herb powder to carry out spinning and produce Chinese medicine regenerated bamboo fiber.The inventive method is simple to operate, and existing wet spinning equipment increases less equipment investment can be reached.The raw material bamboo simultaneously used has the advantages that output is large, raw material is easy to get, cost is low, the solvent used in the present invention, can by simple distillation and recoverable after solvent reaches finite concentration in coagulating bath after using owing to having nonvolatile feature.Therefore whole technological process has the low feature of cost.And the volatilization of organic gas less in whole flow process, ensure that the environment-friendly type of whole flow process.Middle drug fiber manufactured by the present invention has and antibacterial, the health care of the Chinese medicine of Chinese tradition and the lasting function of drug effect slowly-releasing has been joined in fiber, thus generates the novel antibiotic health care had, moisture-absorbing moisture-keeping characteristic Chinese medicine Functiaonl bamboo fiber.
