Description
Technical field
The present invention relates to technical field of biological materials, particularly to the preparation method and application of a kind of high swelling type calcium alginate fibre.
Background technology
Calcium alginate fibre is with alginic acid for raw material, by alginic acid fibre prepared by wet spinning, there is the good characteristics such as the hygroscopicity of excellence, anti-flammability, biocompatibility and biodegradability and be applied to the fields such as textile, medical accessory, interior decoration, bio-absorbable raw material, it is the functional fibre material of a kind of high added value, is also one of current hot fields studied.
In a particular application, its Property requirements is different because application is different for calcium alginate fibre.Swellability and ion exchangeable as required calcium alginate in field of textiles are low, are more beneficial for its weaving；But as nuring wound, bleed, the hospital gauze suppurated, medicinal dressing time, high swelling property, high-hygroscopicity calcium alginate fibre effect more excellent.The hemostatic gauze of the adhesive bandage with similar effect also has this requirement, and therefore this high swelling type special requirement calcium alginate fibre has the market demand widely at field of medicaments
In addition, along with people are original more high to beautiful pursuit, facial film is subject to the favor of consumer as one of quick-acting beauty skin care products always deeply, wherein non-woven fabrics facial film is one of modal facial film kind, also it is daily first-selection, but it is thick and heavy that existing mask nonwoven fabric has quality, moisture absorption, moisture retention is poor, poor air permeability, the shortcomings such as the effect only acting as medium are eliminated just gradually, and high swelling type calcium alginate fibre prepared by the present invention is a kind of desirably one of succedaneum, not only there is high swelling water suction moisture retention, and be derived from natural seaweed and process the calcium having contained by natural seaweed, magnesium, vitamin A, E, the biological nutrients such as C, thus being more than serving as medium, promotion skin blood supply can also be played, the metabolic effect of active cell, just cater to people instantly and pursue nature skin protection, the green idea of skin Caring.There is fabulous market application foreground
But rarely have the report of preparation special requirement " high swelling type calcium alginate fibre " technology at present.Patent " a kind of calcium alginate fibre and its preparation method and application " patent No.: 201210336779.5, adopt the fiber of alginate and the blended preparation of propylene glycol alginate, improve the hygroscopicity of fiber, but it is that sodium alginate obtains with expoxy propane esterification that this kind of method uses propylene glycol alginate (PGA), cost is high, and because expoxy propane is explosive when preparing, dangerous big, there is certain limitation.
Summary of the invention
The invention provides " preparation method and application of a kind of high swelling type calcium alginate fibre " and the deficiencies in the prior art can be overcome, it is provided that a kind of high swelling type, highly hygroscopic, humidity-preserving type calcium alginate fibre.
The technical solution used in the present invention is the preparation method of a kind of high swelling type calcium alginate fibre to achieve these goals, and its feature has the following steps:
(1) preparation quality percentage ratio is 2～4% alginate sol solutions；
(2) preparation quality percentage ratio is the calcium type coagulating bath of 3～8%；
(3) preparation quality percentage ratio is 1～3% composite sodium salt organic solvent ion exchange liquid；
(4) the alginate glue prepared sequentially passes through calcium type coagulating tank, composite sodium salt organic solvent ion exchange liquid groove, and spin processes produces calcium alginate fibre in a wet process.
Technical scheme is improved further: in described step (1), alginate is one or both in sodium alginate, potassium alginate.
Technical scheme is improved further: in described step (1), alginate specification is the viscosity of 1% sol solution 20 DEG C is 150～350mPa.s.
Technical scheme is improved further: in described step (2), calcium type coagulating bath is the aqueous solution of calcium chloride.
Technical scheme is improved further: in described step (3), composite sodium salt is that one or more in sodium chloride, sodium sulfate, sodium carbonate, sodium citrate are composite.
Technical scheme is improved further: in described step (3), organic solvent is one or both in glycerol, ethanol.
Technical scheme is improved further: in described step (4), alginate glue hardening time in calcium type coagulating tank is 3～5min, is 1～3min in the time of composite sodium salt organic solvent ion exchange liquid.
The above-mentioned calcium alginate fibre swellability of the present invention is high, swelling ratio in deionized water > 5%, moisture pick-up properties is strong, can be used for manufacturing the product that the water suctions such as medical adhesive-bonded fabric, facial film Sargassum non-woven fabrics, adhesive bandage, moisture pick-up properties requirement are high.
Compared with prior art, advantages of the present invention and having the benefit effect that
1, the present invention be directed to calcium alginate fibre characteristic needed for medicine, the concrete application of daily use chemicals, the specific technique carried out is studied, and makes product be more suitable for market, improves the competitiveness of product.
2, the technology of this invention makes full use of the ion exchangeable of calcium alginate fibre, plus a compound sodium salt organic solvent exchanger cell it is achieved that cost is low, simple to operate on the basis of existing production line.
3, this invention technical products is one of desirable natural substitute of mask nonwoven fabric, and this has widened its market application.
