Good with human compatibility, be especially suitable for doing medical surgical material, so medical dressing based on alginic acid fibre, gauze,
Binder is just widely applied.
In the preparation of alginate fibre, need to through sodium alginate extraction, produce spinning liquid, spinning, be dried, the step such as coiling,
Conventional drying steps substantially uses hot-air seasoning.Therefore, the fracture strength intelligence of its obtained alginate fibre reaches
About 1-1.1, and the time of hot-air seasoning is the longest, and consumed energy source is relatively costly.
Summary of the invention
It is an object of the invention to provide the high intensity sea that a kind of fracture strength is high, drying time is fast, help the saving energy
The preparation method of algae fiber, to overcome weak point of the prior art.
The object of the present invention is achieved like this:
The preparation method of a kind of high intensity alginate fibre, comprises the following steps:
Step one, produce alginate spinning liquid: alginate is obtained alginate after polyvinyl alcohol blending or crosslinking
Spinning liquid；

Beneficial effects of the present invention is as follows:
The present invention, when prepared by alginate fibre, uses microwave equipment to be dried, instead of traditional air drying methods, it is possible to
It is greatly improved the fracture strength of obtained alginate fibre, and significantly reduces drying time, help raising production efficiency, subtract
The cost of miscellaneous goods, the sorption enhanced rate of microwave is higher, is more beneficial for saving the energy.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
The preparation method of a kind of high intensity alginate fibre, comprises the following steps:
Step one, produce alginate spinning liquid: alginate is obtained alginate after polyvinyl alcohol blending or crosslinking
Spinning liquid；
Step 2, spinning: alginate spinning liquid, obtain fiber filament through wet method or dry-wet spinning；
Step 3, be dried: fiber filament is dried by microwave equipment；
Step 4, coiling: dried fiber filament is made yarn through spinning.
The method producing alginate spinning liquid is: preparation alginate solution and poly-vinyl alcohol solution respectively, according to sea
The solute of alginate soln is 9:1 to 1:1 with the mass ratio of the solute of poly-vinyl alcohol solution, by alginate solution and poly-second
Enolate solution mixes or adds cross-linking agent upon mixing, stirs, vacuum defoamation 24 hours.
Wherein, a kind of or the most two or more by arbitrarily joining during cross-linking agent is oxidized sodium alginate, genipin, glutaraldehyde
The mixture of ratio；Alginate is a kind of or the most two or more by arbitrarily joining in sodium alginate, potassium alginate, ammonium alginate
The mixture of ratio.The method of spinning is through wet method or dry-wet spinning, obtains the fiber filament of alginate composite fiber.
In following process, the yarn obtained by abovementioned steps four can be made looped fabric through knitting machine or loom or spin
Gauze (i.e. binder).
During microwave drying, its preferred parameter is as follows: one, the microwave frequency of microwave equipment is 914 hertz to 2450 hertz
Between.Two, drying time is 3-9 minute, most preferably at about 6 minutes.Three, the power of microwave equipment is 10-20 kilowatt, optimum
It is selected in 15 kilowatts.
As shown in the table: hot-air seasoning and microwave drying alginate fibre contrast table:
| Furnace drying method | Fracture strength | Fiber extensibility | Drying time | Dry power | Dry frequency |
| Hot-air seasoning | 1.1 cN/dtex | 30% | 1 hour | 20 kilowatts | - |
| Microwave drying | 1.9 cN/dtex | 51% | 8 minutes | 18 kilowatts | 914 hertz |
