METHOD AND APPARATUS FOR TREATING MELTBLOWN FILAMENTS |
| 摘要 |
A meltblowing die (11) is provided with means for discharging crossflow air (17) onto meltblown filaments (36) to disrupt their shape and flow pattern between the die and the collector (16). The disruption enhances drag forces imparted by the primary meltblowing air and results in smaller diameter filaments.
