  • Apparatus and process for impregnating fibers with an aerosol of electrostatically charged polymer powder particles
    Patent number: 5328736
    Abstract: Apparatus and continuous process for impregnating fibers with polymer powders in which the fibers are caused to circulate in an aerosol passed through a fluidized bed contained in an earthed fluidization vessel. The particles constituting the fluidized bed are chosen so as to charge the powder particles electrostatically. The aerosol is continuously fed with a flow of fresh powder particles equal to that at which it is desired to impregnate the fibers per unit time and all the powder particles previously introduced which have not been impregnated into the fibers are continuously reintroduced into the fluidized bed without any change in the supply flow rate of fresh powder particles.
