Description

technical field [0001] The invention relates to a magnetic field-induced auxiliary spinning forming device for conductive / magnetic conductive chemical fibers and a production method thereof, belonging to the technical field of functional fiber production. Background technique [0002] With the continuous development of modern industry and electronic consumer industry, the hazards of static electricity and electromagnetic radiation are constantly emerging. Due to the improvement of industrial processing speed, the accidents caused by static electricity are increasing day by day. Due to the phenomenon of static electricity, chemical fiber not only makes spinning and weaving difficult, but also has poor wearing comfort. It can also cause electric shock and even cause serious disasters. Static electricity is one of the main factors causing fires, explosions and other accidents in industries such as pyrotechnics, chemicals, oil, and crushing processing. It is also one of the mai...

Chinese patent CN 200910154049 discloses a method for magnetically inducing multi-walled carbon nanotubes to be ordered in a chitosan matrix. After a certain treatment, a magnetic multi-walled carbon nanotube / chitosan mixed solution is prepared, and then the mixed solution is injected into the In a mold with permanent magnets placed at both ends, this method is simple and low in cost, and realizes the parallel and orderly arrangement and uniform dispersion of multi-walled carbon nanotubes in the polymer. However, this method uses permanent magnets, and the controllability of the magnetic field strength is poor. Not conducive to industrial production

[0005] The above magnetic field-induced auxiliary processing technology is mainly used in the static processing of polymer molding, but for the processing of chemical fiber, which is completed under high-speed shear and tensile flow field, there is no related equipment and Magnetic Field Assisted Induction Molding
