Description
Technical field
The invention belongs to fibre manufacturing technology fields, and in particular to a kind of superabsorbent water alginate fibre and preparation method thereof.
Background technique
Alginic acid (Alginic acid) is a kind of natural polysaccharide, extracted from natural seaweed by monosaccharide aldehydic acid line
Property be polymerized, seaweed acid monomers be β-Isosorbide-5-Nitrae-D-MANNOSE aldehydic acid (M) and α-Isosorbide-5-Nitrae-L- guluronic acid (G), in the application
Alginic acid is usually utilized in the form of alginate, such as sodium alginate, calcium alginate.
Alginate fibre is polysaccharide to extract in natural seaweed as raw material, and water-soluble metal salt solution is coagulating bath, is led to
Cross a kind of novel high-performance fiber that wet spinning production technology obtains.Because of its unique physicochemical property and good bio-compatible
Property, biodegradability, are widely used in pharmaceutical preparation, organizational project, clinical treatment, cell culture, food processing and change
The fields such as adornment industry, for example facial mask cloth can be processed into.
But present common facial mask cloth exists bad with skin affinity, gas permeability is poor, the bad defect of skin sense,
And the biggish facial mask cloth of liquid absorption amount is generally all thicker.Moreover, dispelling in very widely used today skin care item, suncream, whitening
In the cosmetics such as spot, there are many cosmetics to contain the ingredients such as heavy metal, hormone or violated antibiotic to varying degrees.These have
Evil ingredient is easy to accumulate on human skin surface layer, it would be possible to, at any time may be to health as hiding in the intracorporal hidden danger of people
Generate harm.Mainstream facial mask cloth on the market does not have the effect of absorption heavy-metal residual object substantially.
Summary of the invention
The present invention solves the technical problem of in view of the deficiencies of the prior art, providing, a kind of sepiolite calcium alginate is multiple
The preparation method of condensating fiber, obtained by the calcium alginate compounded fibrous mechanical property of sepiolite improve, there is water suction well
Property.
To achieve the above object, the invention adopts the following technical scheme:
A kind of preparation method of superabsorbent water alginate fibre, comprising the following steps:
(1) high-temperature roasting will be carried out after sepiolite coarse crushing, then the sepiolite after roasting is crushed, 400- is made
Sepiolite powder, is then placed in the nitric acid solution of 1-2mol/L by the sepiolite powder of 600nm, and 2h is impregnated at 40 DEG C, and filtering is washed
It washs, it is dry；
(2) sepiolite powder of step (1) after dry is placed in chitosan acetic acid solution, stirs 1h, flax is then added
Oil carries out emulsification 1h, and then adjusting pH value is 6, and the stirring solidification of moderate amount of sulfuric acid sodium is added, and filtering, drying obtain modified meerschaum powder；
(3) gelatin being added in distilled water, then modified meerschaum powder made from step (2) is added in stirring and dissolving dispersion,
Ultrasonic disperse forms homogeneous phase solution；
(4) sodium alginate is added in homogeneous phase solution made from step (3), stirring, preparation obtains sodium alginate quality point
Number is the mixed solution of sodium alginate of 3-8%, is then heated with stirring to 60 DEG C, and water soluble polymer, the microwave at 60 DEG C is added
Oscillation or high-speed stirred 1-2h, obtain uniform spinning solution；
(5) spinning solution that step (4) is prepared carries out deaeration, is ejected to solidification from spinneret through metering pump-metered
In bath；
(6) fiber by step (5) Jing Guo coagulating bath enters washing bath washing, then through drawing-off, drying, rolling step to obtain the final product
The superabsorbent water alginate fibre.
Further, in the step (2), the solid-to-liquid ratio of the sepiolite powder and nitric acid solution is (1-2): 10.
Further, in the step (3), in the homogeneous phase solution, the mass fraction of modified meerschaum is 2-5%, institute
The mass fraction for stating glue clearly is 5-10%.
Further, in the step (4), the water soluble polymer is xanthan gum, chitosan oligosaccharide, polyethylene glycol oxide, shell
One of glycan, gelatin, polyvinyl alcohol, carboxymethyl cellulose are a variety of.
Further, in the step (4), the mass ratio of the water soluble polymer and sodium alginate is 1:(20-
100)。
Further, the concrete operations of the step (5) are as follows: the spinning solution that step (4) is prepared carries out deaeration,
It is ejected in the first coagulating bath through metering pump-metered from spinneret, first coagulating bath is the chlorination that mass fraction is 2-3%
Calcium aqueous solution, the temperature of the first coagulating bath are 50 DEG C, setting time 3-5min；Then it is washed, then drawn with sodium hydroxide solution
Enter into the second gelation, the second gelation is chitosan acetic acid solution, and the temperature of the second gelation is 40 DEG C, when solidification
Between be 20min.
Further, the preparation method of the chitosan acetic acid solution are as follows: the acetic acid that the mass fraction of every 100mL is 1%
3g chitosan stirring and dissolving is added in solution, stirs evenly, standing and defoaming is to get the chitosan acetic acid solution.
Further, the preparation method of the chitosan acetic acid solution are as follows: the acetic acid that the mass fraction of every 100mL is 1%
3g chitosan stirring and dissolving is added in solution, 10% glycerine is then added, stirs evenly, standing and defoaming is to get described
Chitosan acetic acid solution.
Pass through superabsorbent water alginate fibre obtained by above-mentioned preparation method the invention also discloses a kind of.
Compared with prior art, the invention has the benefit that
(1) present invention by sepiolite carry out it is acidified modified after, further through chitosan acetic acid solution stir infiltrate, linseed oil cream
Change, curing and drying can not only improve the adsorptivity of sepiolite, moreover it is possible to which the compatibility for improving sepiolite and sodium alginate makes Hai Pao
Stone can uniformly exist in spinning solution, be homogeneous spinning solution, alginate fibre surface and inside are distributed with after spinning
Sepiolite.
(2) spinning solution is carried out twice coagulating bath by the present invention, and it is compound that first of coagulating bath forms sepiolite alginate
Fiber after the processing by chitosan acetic acid solution, not only can be such that sepiolite is not easy from seaweed subsequently into the second gelation
Fiber surface falls off, moreover it is possible to avoid because alginate fibre flexibility, the defect of poor mechanical property caused by sepiolite is added.
(3) during the preparation process, undope superabsorbent water alginate fibre of the invention other toxic or irritating solvents, former
Material is only sepiolite, sodium alginate and aqueous solution biopolymer, so that superabsorbent water alginate fibre made from this method
With more higher safety, better biocompatibility has good adsorptivity, can adsorb heavy metal, and liquid absorption amount is high,
It can preferably apply in bioengineered tissue material or beauty and make-up field.
Specific embodiment
The following specific embodiments are described below, is described in further details to technical solution of the present invention and effect.
Following the description is used to explain the present invention, rather than limitation of the present invention.
