A liquid dispensing module and nozzle or die tip for discharging at least one liquid filament. The nozzle includes a wedge-shaped member having a pair of side surfaces converging to an apex. A liquid discharge passage extends along an axis through the wedge-shaped member and through the apex. The wedge-shaped member extends in a radially asymmetrical manner around the liquid discharge passage. Four air discharge passages are positioned at the base of the wedge-shaped member. At least one air discharge passage is positioned adjacent each of said side surfaces and each of the air discharge passages is angled in a compound manner generally toward the liquid discharge passage and offset from the axis of the liquid discharge passage.

1. A nozzle for discharging at least one liquid filament onto a moving substrate with a swirled pattern, comprising:a nozzle body having a first side and a second side, said first side adapted to couple with a module body and including a liquid supply port and an air supply port adapted to couple with respective liquid and air supply passages of the module body; a wedge-shaped member on said second side including a base, an apex and a pair of side surfaces converging toward said apex; a liquid discharge passage extending along an axis through said apex of said wedge-shaped member, said liquid discharge passage communicating with said liquid supply port, and said wedge-shaped member extending in a radially asymmetrical manner around said liquid discharge passage; and a plurality of air discharge passages in said nozzle body and positioned adjacent said base of said wedge-shaped member, at least two of said air discharge, passages positioned adjacent each of said side surfaces, and each of said air discharge passages angled in a direction generally toward said liquid discharge passage and offset from the axis of said liquid discharge passage to produce a swirled liquid filament pattern on the substrate upon impact of the liquid filament discharged from said liquid discharge passage.
