Problems solved by technology

[0003] At present, the electrostatic field of electrostatic flocking in the world is a single DC electrostatic field or AC electrostatic field. The flocking speed of the AC electrostatic field is fast, but the implantation depth is shallow. It is necessary to use the action of the impact roller to obtain a better implantation depth of the fluff, so that Improve the flocking fastness, but the action of the impact roller will cause the fluff to be implanted irregularly, the direction will be disrupted, the upright state of the fluff will be destroyed, and the implantation of the subsequent fluff will be affected. The amount of pile will be limited, which will seriously affect the flocking material. Pile density, thus affecting its performance
Although the flocking in the DC electrostatic field is implanted in parallel to the plant body, because the flocking speed in the DC electric field is slower than that in the AC electric field, it is difficult to increase the flocking speed and flocking density at the same time, which makes it difficult to obtain high density under high-speed production conditions. High fastness flocking material
[0004] To sum up, the existing flocking technology is difficult to improve the production efficiency and at the same time ensure the high density of electrostatic flocking products, that is, high amount of flocking, and high fastness

Abstract

The invention provides a multi-electric field electrostatic flocking method and equipment. The method comprises the following steps: coating a base material with an adhesive, and carrying out multi-electric field flocking, fixation, after-treatment and rolling, wherein the multi-electric field flocking step comprises the multiple flocking steps, the time interval between every two flocking steps is 0.5-5 seconds, the flocking is direct current electrostatic field flocking or alternating electrostatic field flocking, and two types of electrostatic fields can be repeatedly or alternately used. Compared with the prior art, the quality of a flocking product is improved, the high-density high-firmness flocking is realized, the production efficiency is improved, the working procedures are reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to a multi-electric field electrostatic flocking method and equipment, belonging to the technical field of electrostatic flocking. technical background [0002] Electrostatic flocking technology is to use the physical characteristics of same-sex repulsion and opposite-sex attraction, so that the fluff is negatively charged, and the object that needs to be flocked is placed under zero potential or grounding conditions, and the fluff is attracted by the different potential and is attracted by the plant body. The vertical acceleration flies to the surface of the object that needs to be flocked. Since the plant body is coated with adhesive, the fluff is vertically stuck to the plant body. Therefore, electrostatic flocking is a new production process that uses the natural characteristics of electric charges. [0003] At present, the electrostatic field of electrostatic flocking in the world is a single DC electrostatic field or AC elec...
