Dissolve soy protein isolate into water-solution of alkali (by weight) to gained solution of soy protein isolate which concentration is 1 - 1.5 g/ml. Mix the solution above symmetrically according to the proper proportion, and then percolate it and deaerating it in low pressture. Prepare blend fiber of sodium alginate/soy protein isolate in coagulation fluid by means of spinning. The stretches ratio is 15 - 20%. The blend fiber has good capability of mechanics.
Description
Technical field
The present invention relates to a kind of sodium acetylide/soybean separation protein commixed fiber and its production and use, belong to the macromolecule chemical material field.
Background technology
Sodium alginate is a kind of natural polymer mixture, 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, sodium alginate dressing has obtained more and more widely application in today.But the sodium alginate fiber has very strong water imbibition, becomes fine back elasticity, intensity all not ideal enough, and its financial cost is also higher in addition.
Summary of the invention
In order to overcome the deficiency of sodium alginate dressing elasticity, intensity difference, the invention provides a kind of sodium acetylide/soybean separation protein commixed fiber and its production and use.The sodium acetylide/soybean separation protein fiber all is better than the sodium alginate fiber at aspects such as mechanical property and water retention values, is particularly suitable for weaving nonwoven fabric as wound dressing, is with a wide range of applications in fields such as medicine, weavings.。
Technical scheme provided by the invention is to adopt following steps to prepare sodium acetylide/soybean separation protein commixed fiber:
(1) sodium alginate being dissolved in pure water, to obtain mass percent be 3～6% sodium alginate soln.
(2) soybean protein isolate being dissolved in mass percent is to obtain the soybean protein isolate solution that concentration is 1～1.5g/ml in 5～10% the strong alkali aqueous solution.
(3) with above-mentioned two kinds of solution be 10%～50% the abundant mixing of ratio in soybean protein isolate shared quality percentage composition in end product, refilter, behind the vacuum deaerator, make sodium acetylide/soybean separation protein fiber with solution spinning in room temperature in solidification liquid, the tensile fiber rate is 15～20%.
But wherein used strong alkali aqueous solution sodium hydrate aqueous solution; Solidification liquid is for containing the CaCl of 5%～10% (mass percent)
2Mixed liquid with the HCl aqueous solution and 30～60% (percent by volume) absolute ethyl alcohol of 1%～5% (mass percent).
This sodium acetylide/soybean separation protein commixed fiber is particularly suitable for weaving nonwoven fabric and makes wound dressing.
The present invention with sodium alginate and soybean separation protein commixed, has improved the performance of pure sodium alginate fiber by the simple and effective method of this raising macromolecular material performance of blending and modifying, eliminates the weakness of its one-component.Again because soybean protein isolate is a accessory substance behind the soybean extract oil, the globular protein that it is made up of several amino acids, the source is abundant, cheap, so the present invention also has simple, the lower-cost advantage of preparation method.
