Abstract
The present invention discloses a blend fiber of sodium alginate/ gelatin and its usage and preparation. The blend fiber of sodium alginate/ gelatin is made as following ways: Dissolve right amount of the sodium alginate into pure water to gained solution of sodium alginate which concentration is 3 - 5% (by weight); Dissolve right amount of gelatin into water which temperature is 80 - 90 Deg. C to gained solution of gelatin which concentration is 10 - 20% (by weight); Mix the solution above at the ratio of gelatin contains 10 - 70% of the production (blend fiber), and then percolate it and deaerating it in low pressture. Prepare blend fiber of sodium alginate/gelatin in coagulation fluid by means of spinning. The stretches ratio is 10 - 30%. The blend fiber has good capability of biological activity, good capability of mechanics and water-absorptivity. It has good prospect in the domain of medicine, weave and so on, especially for for chitosan nonwoven as dressing of wound.
Description
Technical field
The present invention relates to a kind of blended fiber of sodium alginate/glutin of making nonwoven fabric and its production and use that is used to, belong to the macromolecule chemical material field.
Background technology
Alginic acid is by β-1, and 4-D-mannuronic acid and α-1, the heteroglycan that the 4-L-glucuronic acid is formed.With Ca
2+Solution is solidification liquid, and sodium alginate can be made fiber by the hygrometric state spin processes.Ca in the fiber
2+Can with the Na in the human body wound exudate
+Carry out ion-exchange and suffering from mouthful place's formation hygrometric state gel.Owing to have these two advantages of human body absorbability that can form hygrometric state wound healing environment and height, alginic acid dressing has obtained more and more widely application in today.But the elasticity of alginic acid fibre, intensity are all not ideal enough, and its financial cost is also higher.Gelatin is the soluble mixtures of polypeptides of a kind of hot water, is to be got by the collagen hydrolysate in the connective tissues such as the skin that is present in higher mammal, bone, because it and biological tissue have good compatibility, thereby it is widely used at medical domain.Studies show that: gelatin has activated macrophage and anastalsis, and it often is used to make wound dressing, hemostatic material and artificial skin, but owing to membranous crisp, the poor mechanical property of gelatin, is widely used thereby limit it.
Summary of the invention
The present invention is directed to all dissatisfactory shortcoming of elasticity, intensity of alginic acid fibre, simple and effective method by this raising macromolecular material performance of blending and modifying, with sodium alginate and gelatin cross-blend with hemostatic function, provide a kind of combination property comparatively desirable blended fiber of sodium alginate/glutin, this blended fiber has excellent mechanical property, and the present invention also provides the method for preparing blended fiber of sodium alginate/glutin, and this method simple possible, cost are lower.
Technical scheme provided by the invention is to adopt following method to prepare blended fiber of sodium alginate/glutin:
(1) be 3～5% sodium alginate soln with the water-soluble mass percent that obtains of an amount of sodium alginate;
(2) an amount of gelatin is dissolved in to obtain mass percent in 80～90 ℃ of water be 10～20% gelatin solution;
(3) with above-mentioned two kinds of solution be 10%～70% the abundant mixing of ratio in gelatin shared mass percentage content in product (blended fiber), after filtration, behind the vacuum deaerator, prepare blended fiber of sodium alginate/glutin with solution spinning in room temperature in the capacity solidification liquid, the tensile fiber rate is 10～30%.
Wherein used solidification liquid is 5%～10%CaCl for containing mass percent
2The mixed liquid of the aqueous solution and 30～50% (percent by volume) absolute ethyl alcohol.For reducing the impurity in the product, preparation sodium alginate soln, the used water of gelatin solution are preferably distilled water.
Because blended fiber of sodium alginate/glutin not only has the advantage of sodium alginate fiber and gelatin, and mechanical property and water imbibition are also fine, abundant because of its raw material sources again, low price, so be with a wide range of applications, especially be suitable for making nonwoven fabric and make wound dressing usefulness at medical field.
The specific embodiment
Embodiment 1: get the 45g sodium alginate and be dissolved in the sodium alginate soln that 855ml distilled water obtains 5% (mass percent); Get the 5g gelatin and be dissolved in the gelatin solution that obtains 10% (mass percent) in 90 ℃ of distilled water.With above-mentioned two kinds of abundant mixings of solution, behind filtration, the vacuum deaerator, consisting of 5% (mass percent) CaCl in room temperature
2The solidification liquid of mixed liquid of the aqueous solution and 30% (percent by volume) absolute ethyl alcohol in prepare blended fiber of sodium alginate/glutin by solution spinning, the tensile fiber rate is 30%.
Embodiment 2: get the 35g sodium alginate and be dissolved in the sodium alginate soln that 840ml distilled water obtains 4% (mass percent); Get the 15g gelatin and be dissolved in the soybean protein isolate solution that obtains 15% (mass percent) in 90 ℃ of distilled water.With above-mentioned two kinds of abundant mixings of solution, filter, behind the vacuum deaerator, consisting of 7% (mass percent) CaCl in room temperature
2The solidification liquid of mixed liquid of the aqueous solution and 40% (percent by volume) absolute ethyl alcohol in prepare blended fiber of sodium alginate/glutin by solution spinning, the tensile fiber rate is 20%.
Embodiment 3: get the 25g sodium alginate and be dissolved in the sodium alginate soln that 808ml distilled water obtains 3% (mass percent); Get the 25g gelatin and be dissolved in the gelatin solution that obtains 20% (mass percent) in 90 ℃ of distilled water.With above-mentioned two kinds of abundant mixings of solution, filter, behind the vacuum deaerator, consisting of 10% (mass percent) CaCl in room temperature
2The solidification liquid of mixed liquid of the aqueous solution and 50% (percent by volume) absolute ethyl alcohol in prepare blended fiber of sodium alginate/glutin by solution spinning, the tensile fiber rate is 10%.
Because of solution spinning is the conventional method of preparation fiber, no longer it is elaborated here.
Embodiment 1,2,3 products therefroms are carried out mechanical property and water absorption rate test, and test result sees the following form.
By data in the table as can be known, blended fiber of sodium alginate/glutin has excellent mechanical property and water imbibition.
