Description
Technical field
The present invention relates to the man-made cellulose fibers technical field, relating in particular to a kind of is the composite fibre of main raw material by cellulose and alginate, the invention still further relates to the preparation method of cellulose/alginate composite fiber.
Background technology
Alginate is a kind of natural polymer of being made up of β-D mannonic acid aldehydic acid salt and the linear copolymer that α-L guluronic acid salt (1 → 4) is connected.The application of alginate on health care originates from the invention of " wet method therapy ", alginate can interact with wound exudate and generate wet gel, on the wound original position, produce wet treatment environment, thereby the promotion wound healing is accelerated because the inflammation healing that scytitis, ringworm and allergic reaction cause.Alginate has very high hygroscopicity simultaneously, thereby is particularly suitable for medicine and hygiene fields, and protection plays an important role to health.
Chinese patent application CN1297957 discloses a kind of cm-chitosan and alginic acid blend film or fiber preparation method, its manufacture method is with carboxymethyl chitosan sugar aqueous solution and sodium alginate aqueous solution blend, obtain blend film or fiber through knifing or wire drawing, again with this film or fiber CaCl
2The aqueous solution is handled, after the cleaning again with regenerating the product of gained after the clean dry in the HCl aqueous solution.Chinese patent application CN1687496 discloses a kind of sodium acetylide/soybean separation protein commixed fiber and preparation method thereof, its manufacture method is that the raw material sodium alginate is dissolved in pure water, soybean protein isolate is dissolved in the strong alkali aqueous solution, two kinds of solution by mixing, are prepared the sodium acetylide/soybean separation protein fiber by solution spinning in solidification liquid.Chinese patent application CN1687498 discloses a kind of blended fiber of sodium alginate/glutin and preparation method thereof, its manufacture method is that sodium alginate is water-soluble, gelatin is water-soluble, two kinds of solution are mixed, in solidification liquid, prepare blended fiber of sodium alginate/glutin with solution spinning.
Mostly the preparation of above-mentioned alginic acid fibre is the method for employing and non-alginic acid high polymer co-spun yarn, but because sodium alginate has been sneaked into other high polymer compositions, the physical and mechanical properties of gained final finished fiber is all relatively poor, fiber strength, degree of stretching are all lower, its application only is confined to some specific area, has limited the range of application of this kind fiber greatly.
Summary of the invention
First technical problem to be solved by this invention is: a kind of cellulose/alginate composite fiber is provided, and poor to solve known alginate fibre physical and mechanical properties, the problem that the fiber strength and elongation is low.
Second technical problem to be solved by this invention is: a kind of method for preparing cellulose/alginate composite fiber is provided.
For solving above-mentioned first technical problem, technical scheme of the present invention is: described alginic acid composite fibre mainly is made up of according to following weight parts cellulose and sodium alginate,
Cellulose 99.8～85 weight portions;
Sodium alginate 0.02～15 weight portion.
As with a kind of design, for solving above-mentioned second technical problem, technical scheme of the present invention is: the preparation method of cellulose/alginate composite fiber, comprise the steps,
A) under 18～75 ℃ temperature conditions, ratio according to weight ratio 1: 15～120 is dissolved in sodium alginate in the deionized water, again in the NaCl or the KCl solution that add 0.01～0.5mol/l with respect to the ratio of sodium alginate 0.2%～2%, through 4～24 hours continuous stirring, obtain the viscosity solution that viscosity is 5～15Pa.S; And in described viscosity solution in sneaking into aloe gel with respect to the ratio of sodium alginate 0.2～5%;
B) under the temperature conditions of 35 ℃, 36 ℃, 38 ℃ or 39 ℃, cellulose pulp was alkalized 0.4～4 hour through the NaOH of 200～300g/l solution, generate alkali cellulose, 20～45 ℃ were descended experienced 0.3～16 hour, obtain the alkali cellulose of cellulose 25～35%, add CS again with respect to cellulose 35～65%
2Reacted 2～6 hours, and obtained cellulose xanthate;
C) solution of described cellulose xanthate with 0.2%～10% the sodium alginate that is equivalent to content of cellulose is fully mixed, stir and obtain spinning solution after 4 hours;
D) with described spinning solution in spinning head is pressed into 25～50 ℃ coagulating bath, through drawing-off, sodium alginate and cellulose xanthate solidify and are regenerated as the composite fibre that sodium alginate and cellulose are formed; Described coagulating bath is by 30～100g/lH
