Cold air meltblown apparatus and process |
摘要 |
An apparatus and process for producing meltblown fibers employs a coflowing primary cold air flow and secondary hot air flow in a meltblowing nozzle. The primary cold air flow provides the majority of the force used to attenuate the polymer stream into fibers, while a secondary hot air flow shrouds the die tip and prevents premature quenching. |
