Novel Bonding Process for CBW Protective Electrospun Fabric Laminates Phase 2

摘要

Report developed under Small Business Innovation Research contract. Electrospun membranes for CBW protective fabric were modeled, developed, and tested. Theoretical models for gas permeation, as well as filtration efficiency, were developed as functions of fiber diameter. The effects of varying the process variables on the fiber morphology were also explored. The mechanical properties of the electrospun nonwoven fabrics were tested, as well as the filtration efficiency of electrospun Estane membranes. Bead-free Estane membranes were evaluated for filtration efficiency using custom fabricated test equipment and showed filtration efficiencies in excess of 98.5% against 1 micron polystyrene-latex spheres.
