Windmill palm fiber/polyvinyl alcohol nonwoven fibrous polymeric materials

Abstract

Three types of wet-laid nonwoven materials with windmill palm fibril (WPFL), WPFL /windmill palm fiber bundles (WPFB) and windmill palm fiber (WPF)/polyvinyl alcohol (PVA), were prepared. The morphology and length distribution of WPFL and WPFB were analyzed by digital microscopy and image processing software. The filtration efficiency, air permeability and sound absorption properties of 12 samples of wet-laid nonwoven materials were tested. Adding PVA improved the porosity and enhanced the filtration efficiency, air permeability and acoustic properties of the nonwovens.
