The invention discloses a flocking plant of a screen printing process. The flocking plant comprises a conveyer belt and a plurality of platens on the conveyer belt, wherein a screen printing unit or a flocking unit are arranged on each platen; the quantity of the screen printing units and the quantity of the flocking units are both equal to or greater than 2; each flocking unit comprises a rack box as well as a flock box, a filter screen, a positive power grid and a screen frame in the rack box; and the lower sides of the screen frames directly face toward the patens. During the use, the filter screens are used as cathodes and the positive power grids are used as anodes to electrify so as to form electric fields between the filter screens and the positive power grids; the electric fields are used for sucking the flocks out from the flock boxes; the sucked flocks pass through the filter screens, the positive power grids and the screen frames in sequence, and then fall on the cloth on the patens so as to complete the flocking of sub-flocking patterns; each sub-flocking pattern corresponds to one flocking unit; and after the patens pass through all the flocking units along the conveyer belt, the flocking of the whole pattern is completed. The flocking plant is relatively high in efficiency of multicolor or multi-pattern flocking, relatively strong in safety, relatively strong in environment-friendliness and relatively high in recovery efficiency.
