A fiber deposition method that can improve uniformity

Abstract

The application discloses a fiber deposition method capable of improving uniformity, which comprises the following steps: applying a spinning electric field between a receiving device and a nozzle device; the receiving device is provided with a concave-convex structure, and an electric field intensity difference is formed on the concave-convex structure, so that high electric field intensity positions and low electric field intensity positions are formed on the receiving device; a plurality of high electric field intensity positions and a plurality of low electric field intensity positions are staggered in an advancing direction and a width direction; and a base material advances along the advancing direction and passes through the high electric field intensity positions and the low electric field intensity positions which change alternately. The attraction of the high electric field intensity positions to the jet in the air is greater than the attraction of the low electric field intensity positions to the jet, so that the attraction caused by the high electric field intensity positions is added to the attraction of the base material on which the fibers have been deposited to the jet; the staggered high electric field intensity positions form staggered attractions to a plurality of jets formed by a plurality of nozzles, so that the fibers deposited on the base material are more uniformly distributed.
