Embodiment 1
[0017] Step 1: Mix sodium alginate and water to obtain a sodium alginate solution, wherein the mass of sodium alginate is 520g, the water is 4L, the mixing temperature is 45°C, and the mixing time is 45min. Add the sodium alginate solution into the flask, And after adjusting the pH of sodium alginate, add NaHCO with a concentration of 8mol / L 3 solution, so that the pH of the solution is 6, after the reaction is over, add ether to the beaker to mix and filter to obtain a filter residue, which is washed with ether;
[0018] Step 2: The sodium alginate solution prepared in step 1 is subjected to degassing and wet spinning to obtain sodium alginate primary fibers, and the sodium alginate primary fibers are stretched, shaped, dried, and spun to obtain sodium alginate cloth;
[0019] Step 3: Soak the sodium alginate coat prepared in Step 2 in 4L of 3mol / L zinc borate solution for 10 hours, and keep the temperature at 30°C;
[0020] Step 4: Put the soaked sodium alginate cloth in a...
