A meltblowing method and system for dispensing first and second fluids (F1,F2) from corresponding first and second orifices of a die assembly (100) to form a meltblown first fluid filament (FF). The die assembly (100) directs the first and second fluid flow flows parallelly, or divergently, or directs the two second fluid flows convergently toward a common first fluid flow, whereby the first and second fluids are dispensed from orifices at equal first fluid flow rates and equal second fluid flow rates. The die assembly (100) is compressibly retained between opposing end plates (160,170) coupled to an adapter (320) for further coupling to a main manifold (10) having a fluid metering device (210) for supplying first fluid to the die assembly. The meltblown filaments are depositing onto a moving substrate (S) by vacillating the filament non-parallel to a direction of substrate movement, whereby vacillation a first fluid flow is controllable by an angle between the first fluid flow and one or more flanking second fluid flows, among other variables. <IMAGE> |
