Abstract
A process for predicting and adjusting particle removal efficiency of fiber-based filter media based on quantification of disorder. An order parameter may be extracted through Raman spectroscopy or scanning electron microscopy. Production processes may be adjusted to change (e.g., increase) the particle removal efficiency of fiber-based filter media utilizing a predefined correlation between order parameter and particle removal efficiency. The filter media may be utilized in masks, filters, and other applications.
