Patent ID: 6946093

Claim:
A method of meltblowing first and second liquid materials into multi-component filaments, comprising: feeding the first liquid material into a first liquid inlet; feeding the second liquid material into a second liquid inlet; passing the first liquid material between a first outer surface of an intermediate manifold element and a first opposed surface of a first outer manifold element; passing the second liquid material between a second outer surface of the intermediate manifold element and a second opposed surface of a second outer manifold element; directing the first and second liquid materials, respectively, from passages located between the intermediate manifold and the first and second outer manifolds into first and second elongate slots extending along a lengthwise dimension of a die tip; discharging multi-component filaments comprised of the first and second liquid materials from the die tip; and impinging the discharged multi-component filaments with process pressurized air from the die tip.
