AUFLADEGERÄT UND VERFAHREN FÜR SCHMELZGEBLASENE VLIESSTOFFE

摘要

Electrically charged meltblown webs are formed by convergingly discharging electrically charged hot air onto a row of extruded polymer fibers to contact the fibers thereby (i) attenuating and stretching the fibers and (ii) imparting an electric charge to the fibers. The fibers may be continuous or discontinuous.
