Manufacture of Composite Nanofiber Mats with Fiber Diameters Grads by Electrospinning for Filtration Use
The objective of this study is to prepare a filtration material with fiber diameter grade by electrospinning technique using meltblown nonwovens as collecting materials. The average fiber diameter of PET electrospinning in the top layer was 309.60nm and PET meltblown nonwoven in the bottom layer was 1.82um respectively. And this structure leads to the average pore size of electrospinning-meltblown composite material was 0.73um while it is up to 5.36um for the PET meltblown nonwoven. This design is especially good for high accurate filtration such as cells filtration, hydronium filtration.
