Research and development of nanofibres has gained significant prominence in recent years due to the heightened awareness of their ability to enhance the performance of various forms of filter media. Nanofibre technology, i.e. the fabrication of very small fibres typically having a diameter of less than I micron, has been known and practiced for many years. Currently, the most commonly used process for manufacturing nanofibres is the electrospinning process. This article highlights the drawbacks of the electrospinning process as compared to a new process, nanofibre coating. Further discussed are the advantages of using a nanofibre coating in filtration applications to improve depth filtration and pulse cleaning ability.
