METERING MELTBLOWING SYSTEM |
摘要 |
A meltblowing system with a modular die design and on-line monitoring of web properties is described. The modular die consists of individually fed side-by-side meltblowing units. Automated control of the polymer feed rates to the units have been shown to produce a web with excellent uniformity of basis weight. The die also features a valve assembly for minimizing polymer afterflow and die tip plugging. |
