Description
Technical field
The invention belongs to functional textile fibrous material fields, and in particular to a kind of warming chitin fiber and its preparation
Method.
Background technique
The research and development of warming fiber are always one of the hot issue of functional textile developing material.Currently, existing in the market
Warming fiber exploitation be mainly following two in terms of: one kind is to realize far infrared transmission function by adding inorganic particle
Energy (such as CN201410546018.1), but this warming fiber is not suitable for the articles of pregnant woman, this kind of special population of children, and
And the crowd bad for heart should not also use；Another kind of is by fiber moisture absorption heat release to achieve the effect that fever (such as
CN201110098693.9), but the fiber there are certain limitations in terms of material, and heating effect is also bad.
Chitosan has the excellent properties such as good biocompatibility and antibacterial as a kind of emerging fibrous material.However
Chitosan causes it to be difficult to dissolve due to a large amount of intermolecular and intramolecular hydrogen bond, meanwhile, it is conventional to be prepared into using acid flux material
To chitosan material there is a problem of that mechanical property is more crisp, in addition, chitin fiber is assigned as a kind of novel textile fabric
Its application range can further be expanded by giving its different functionality.
Capsaicine can have an impact a kind of muscle protein for being SERCA, usual feelings as the active constituent in capsicum
Under condition, SERCA consumes a kind of molecule fuel of ATP() by the calcium channel on calcium ion " pump " cell membrane.Under certain condition,
The ATP that capsaicine can promote SERCA to consume can only be discharged in the form of heat, to reach the effect for making to dress position heating
Fruit.In addition, capsaicine has very good biocompatibility as natural alkaloid, promote blood circulation.Shell is prepared at present
Glycan/capsicum cellulose fiber work report is more rare, main reason is that capsaicine is also not readily dissolved in general solvent, energy
A kind of enough technologies that cellulose is dissolved in solvent jointly with capsaicine are relatively difficult to achieve.
Summary of the invention
The purpose of the present invention is being directed to above-mentioned existing invention, a kind of novel warming chitin fiber is provided
And preparation method thereof.Specific technical solution is as follows:
A kind of preparation method of warming chitin fiber, the ingredient of the warming chitin fiber are chitosan and capsaicine, packet
It includes the preparation of capsaicine/chitosan solution and wet spinning prepares two step of fibrous material.
Wherein capsaicine/chitosan solution preparation includes following process: step 1: capsaicine is dispersed in LiOH/ urine
It in plain aqueous solution, quickly stirs evenly, obtains capsaicine mixed solution；Step 2: chitosan is added simultaneously in the above solution
And KOH, mechanical stirring 5-30 minutes, system temperature was reduced to -30 ~ -50 DEG C, finally obtains capsaicine/chitosan solution, it should
The content of LiOH, KOH and urea is respectively 2 ~ 6wt%, 5 ~ 10wt% and 10 ~ 16wt% in capsaicine/chitosan solution.
The capsaicine being added is natural capsicum element, and the content of capsaicine is 0.5 ~ 1.5wt%.
The step of capsaicine/chitosan solution is prepared into warming chitin fiber through wet spinning are as follows: will be dissolved peppery
Spinning solution is made in green pepper element/chitosan solution after filtering and impurity removing, vacuum defoamation, and spinning solution is under the conditions of suppressing through spinneret
Plate is immersed in coagulating bath and is regenerated, and as-spun fibre is washed, oiled after regeneration, baking step obtains filament fiber.
Since the intensity requirement in long filament preparation process for as-spun fibre is higher, when preparing filament fiber, coagulating bath
It can be 35-75 DEG C for ethylene glycol or the aqueous solution of sodium sulphate, coagulation bath temperature.
To guarantee the spinnability of wet spinning, and make the fibrous material being prepared that there is preferable mechanical property,
The viscosity average molecular weigh of chitosan should be controlled 8 × 104 ~15 × 104In the range of；Since chitosan is easy in process
Embrittlement, drying course should be 60-90 DEG C using the method for staged heating drying, drying temperature.
It is yet another object of the invention to provide the applications of above-mentioned warming chitin fiber, using warming shell prepared by the present invention
Glycan fiber can be applied to production underwear, socks, heating knee pad, heating waist support alternate product.
Compared with reported method, the present invention has apparent technical advantage and significant using effect.
1) it is dispersed in capsaicine is organic in chitin fiber matrix, selection capsaicine is heating composition, biofacies
Capacitive is good, degradable, highly-safe.
2) present invention uses same alkali/urea solvent, efficiently uses each component in solvent and is formed with hydroxyl, amino and carbonyl
The ability of hydrogen bond, by capsaicine and chitosan co-dissolve in the solvent, and we have discovered that successively by capsaicine and shell
Glycan fiber is distributed to the total dissolution that can be optimal in solvent and dispersion effect.By selecting suitable coagulator, preparation
There is obtained warming chitin fiber porous structure to make capsaicine evenly dispersed, and fibre strength obtained can achieve
1.5-3.8 cN/dtex, elongation at break reaches 7-15%.Since capsaicine can be uniformly dispersed in glycan substrate, because
This fiber and have the advantages that stablize, it is wash fast.It is fine to gained spontaneous heating with the sodium dodecyl sulfate solution of 1-3wt%
Dimension is washed, and is washed 20-80 times and is differed, keeps 95% or more of primary heat function.,
3) application prospect of such warming chitin fiber is wide, and utility value is high, manufactured underwear, socks, heating knee pad, fever
Waist support alternate product has warming and certain health-care efficacy of warding off the cold.
