Designing Unidirectional Moisture Transport Fabric Based on PA/CA Membrane Fabricated by Electrospinning

In this research, cellulose acetate/blends of polyvinyl alcohol and polyacrylic acid (CA/PA) bilayer porous membrane was prepared by electrospinning and esterification. Then the developed membrane was laminated onto polyester fabrics to examine their practical applications in the textile area. Investigations for surface morphology, the water content distribution and the moisture absorption were done in detail to examine the unidirectional moisture transport performance of the CA/PA bilayer porous membrane and the laminated fabrics. The results illustrated that when the electrospinning arrangement time was PA-CA=6h-4h, the lamination pressure 2 MPa and the lamination time 35 seconds, the laminated fabric had the best performance. At this time, the composite laminated fabric exhibited a value for one-way moisture transport capability (R) of 960.76 % with overall moisture management capacity (OMMC) performance of 0.84 %. Additionally, the moisture absorption and perspiration of the laminated fabric can reach level 5.
