Embodiment 1

[0011] Under the condition of heating in a water bath at 60°C, the sodium alginate was dissolved in deionized water, and after 8 hours of continuous stirring, a 5% solution was prepared. Add sodium hypochlorite to the prepared solution at a ratio of 0.02ml volume relative to the mass of sodium alginate per gram, and stir for another 6 hours under the condition of a water bath at 60°C to obtain a solution with a viscosity of 14000-15000 mPa·s.

[0012] After filtering, degassing for 8 hours to prepare spinning solution. Then, at a speed of 12.9m / min, it passes through a 60-hole spinneret with a diameter of 0.075mm into a coagulation bath at a temperature of 30°C. The coagulation bath is BaCl with a mass fraction of 11% 2 Solution. After the first coagulation bath, the fiber enters a water bath with a temperature of 70°C for stretching. Among them, the first drawing roller is negative drawing, the linear speed is 9.4m / min, and the second drawing roller is about 100% stretching, and ...

[0014] Under the condition of heating in a water bath at 60°C, the sodium alginate was dissolved in deionized water, and after 8 hours of continuous stirring, a 5% solution was prepared. Add sodium hypochlorite to the prepared solution at a ratio of 0.02ml volume relative to the mass of sodium alginate per gram, and stir for another 6 hours under the condition of a water bath at 60°C to obtain a solution with a viscosity of 14000-15000 mPa·s.

[0015] After filtering, degassing for 8 hours to prepare spinning solution. Then, at a speed of 12.07m / min, it passes through a 60-hole spinneret with a diameter of 0.075mm into a coagulation bath at a temperature of 30°C. The coagulation bath is ZnSO with a mass fraction of 13% 4 Solution. After the first coagulation bath, the fiber enters a water bath with a temperature of 70°C for stretching. Among them, the first drawing roller is negative drawing, the linear speed is 9.4m / min, the second drawing roller is 130% stretching, and the linea...

Embodiment 3

[0017] Under the condition of heating in a water bath at 60°C, the sodium alginate was dissolved in deionized water, and after 8 hours of continuous stirring, a 5% solution was prepared. Add sodium hypochlorite to the prepared solution at a ratio of 0.02ml volume relative to the mass of sodium alginate per gram, and stir for another 6 hours under the condition of a water bath at 60°C to obtain a solution with a viscosity of 14000-15000 mPa·s.

[0018] After filtering, degassing for 8 hours to prepare spinning solution. Then, at a speed of 11.8m / min, it passes through a 60-hole spinneret with a diameter of 0.075mm into a coagulation bath at a temperature of 40°C. The coagulation bath is CuSO with a mass fraction of 7.2% 4 Solution. After the first coagulation bath, the fiber enters a water bath with a temperature of 70°C for stretching. Among them, the first drawing roller is negative drawing, the linear speed is 9.5m / min, the second drawing roller is 150% stretching, and the linea...

Abstract

The invention relates to a multi-ion alginate marine fiber, wherein metal cation of multi-ion alginate is barium, zinc or copper ions or mixture of random two or more ions, or the mixture of random one or more ions and calcium ions. The invention further relates to the process for preparing the multi-ion alginate marine fiber.

Description

Technical field [0001] The invention relates to a multi-ion alginate marine fiber. The invention also relates to a preparation method of the polyion alginate marine fiber. More specifically, the present invention relates to a multi-ion alginate marine fiber and a preparation method thereof, wherein the metal cation in the multi-ion alginate is barium, zinc or copper ion, or any two or more of them A mixture of ions, or a mixture of any one or more of them with calcium ions. Background technique [0002] The marine resources are rich in reserves and varieties, without pollution to the environment. Therefore, marine resources have unique advantages compared with petroleum resources. The most prominent marine resource is sodium alginate, which is made from natural seaweed and has a wide range of sources. The alginate (alginate M) fiber made from sodium alginate has good strength, elasticity and has anti-bacterial and anti-electromagnetic radiation functions, so it can be produced in...
