Abstract

The invention belongs to the field of fiber manufacturing and relates to a fiber manufacturing device and process. The fiber manufacturing process refers to a melt spinning process, and melt is prepared by steps: step one, preparing a-Al2O3 coated magnetic material particles; step two, mixing the a-Al2O3 coated magnetic material particles obtained at the step one with other fiber materials, and melting to obtain the melt. The magnetic particles which are a-Al2O3 coated magnetic material particles are included in the melt prepared according to the process. By external coating of a magnetic material with high-strength a-Al2O3, on the one hand, strength and toughness of obtained fibers can be improved, and on the other hand, due to high melting point of a-Al2O3, wrapping the magnetic materialinside avoids magnetism loss of inner magnetic substances due to reaction with other fibers.

Description

technical field [0001] The invention relates to a fiber manufacturing device and process, belonging to the field of fiber manufacturing. Background technique [0002] Magnetic fibers are chemical fibers that contain magnetic substances and are magnetic. Currently, fiber preparation methods mainly include melt spinning and solution spinning. Fiber-forming polymers that generally do not decompose significantly in the molten state are melt-spun, such as polyester fibers, polyamide fibers, and the like. The melt spinning process is simple, the spinning speed is high, and it is the most widely used spinning method. At present, there are many methods for preparing magnetic fibers by melt spinning, such as wrapping or attaching a layer of magnetic material on the existing fibers, so that the obtained fibers can obtain certain magnetic properties. It is also possible to mix the magnetic material into the slurry for preparing the fiber when the fiber is prepared, so that the magne...
