Embodiment 1
[0022] Embodiment 1 Preparation of blended fiber of the present invention
[0023] Prepare a polyacrylonitrile solution with a mass concentration of 15% and a polyvinyl alcohol solution with a mass concentration of 15%; prepare a cellulose solution with a mass concentration of 5%, and vacuum-dry chitosan and polylysine (70°C, vacuum under the condition of 100Pa and vacuum drying for 12 hours, the drying temperature is 45), and then added to the cellulose solution at 50°C to obtain the spinning stock solution, and the spinning stock solution was mixed with polyacrylonitrile solution and polyvinyl alcohol solution at 75°C uniform, so that the solution contains 60 parts of natural cellulose, 10 parts of polylysine, 3 parts of polyacrylonitrile, 2 parts of polyvinyl alcohol, and 0.5 part of chitosan, and the mixed mixture is extruded by a twin-screw extruder to obtain Blending the tow; washing the blended tow through a water tank to remove the ionic liquid, stretching, drying, cro...
