MELTBLOWING METHOD AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide novel meltblowing method and system for applying meltblown adhesives onto moving substrates.

SOLUTION: The meltblowing method comprises dispensing a first fluid from a first orifice to form a first fluid flow at a first velocity, dispensing a second fluid from second orifices corresponding to the first orifice at a second velocity along substantially opposing flanking sides of the first fluid flow to form separate second fluid flows, directing the separate second fluid flows convergently toward the first fluid flow and drawing the first fluid flow with the separate second fluid flows at a second velocity greater than the first velocity of the first fluid flow, wherein the drawn first fluid flow is attenuated to form a first fluid filament and to be applied to the substrate.
