Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the preferred embodiments of the present invention.
[0022] The preparation method of nano silver wet spinning chemical fiber is characterized in that it comprises the following steps:
[0023] 1) Preparation of nano-silver colloid solution: dissolving nano-silver colloid powder in an organic solvent to form a 50g / L nano-silver colloid solution;
[0024] 2) Preparation of spinning stock solution: mixing the fiber-forming high polymer organic solution with nano-silver colloidal solution, then stirring, filtering and defoaming to obtain the spinning stock solution;
[0025] 3) Spinning and winding: Spin the spinning dope through the spinneret and enter the coagulation bath to form fibers, and finally wind the fiberized chemical fibers into fixed packages.
[0026] It should be pointed out that the volume ratio of the fiber-forming high polymer organic solution and the nano-silver colloid solutio...
