Waterproof and Moisture Permeability Performance of Laminated Fabrics with Electrospun Nano Fibrous Membrane

Abstract

A waterproof and moisture permeable fabric was fabricated by laminating polyester (PET) or polyurethane (PU) electrospun nano fibrous membranes inside of common blended fabrics, and the obtained laminated fabrics had good waterproof and moisture permeable performance. The waterproof and water permeable performance of the laminated fabrics were dependent on the component and thickness of the electrospun nano fibrous membranes that laminated inside by hot pressing. The laminated fabric with PET/PU composite electrospun nano fibrous membrane as functional layer has excellent moisture permeability of up to 8.82kg/(m2•d), air resistance value of 6.2kPa/(s•m) and hydrostatic pressure of 36.1cm H2O, respectively. Moreover, the hydrostatic resistance of the laminated fabric combined with PU electrospun nano fibrous membranes is higher than that of the laminated fabric combined with PET nano fibrous membranes and has a better hand feeling as well.
