- Abstract
In order to improve the air filtration efficiency of polypropylene (PP) melt-blown nonwoven, polyacrylonitrile (PAN)/PP composite fiber membrane was prepared by electrospinning, and the effects of process parameters on its filtration efficiency, air filtration resistance and anti-bacterial performance were studied. Test results showed that filtration efficiency of the composite fiber membrane with both salt and oil particles was significantly improved compared with PP melt-blown nonwoven. The filtration efficiency of salt particles and oil particles could be reached the highest as the spinning solution concentration was 12%, the spinning voltage was 10 kV, and the spinning time was 90 min. When the spinning solution concentration was 10% and the spinning voltage was 10 kV, the anti-bacterial performance of the composite fiber membrane was enhanced with the increase of spinning time. After 90 min of electrostatic spinning, the composite fiber membrane already had a specific anti-bacterial performance. It is considered that the prepared PAN/PP composite fiber membrane has certain advantages as filter elements for breathing protection, such as masks.
