Nanofibre Production by Meltblown Enhancement
topic
Nanofibre meltblown production uses modified die designs with sub-100 micrometre orifices, very high air velocities above 500 metres per second, and high-MFI polymer grades to produce fibres approaching 500 nanometre diameter, with Nanoval process and similar advanced meltblown techniques achieving nanofibre diameter ranges that intermediate between conventional meltblown and electrospinning in both production rate and fibre fineness.
Role
Extends meltblown fibre diameter below one micrometre toward the nanofibre range that provides superior filtration efficiency from reduced interfibre pore size, positioning advanced meltblown nanofibre production as a higher-throughput alternative to electrospinning for filtration media requiring nanofibre performance at production rates compatible with commercial filtration media manufacturing economics.
