FILTER MEDIUM FOR AIR FILTER HAVING ELECTROSTATIC SPINNING NANOFIBER LAYER, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a filter medium for an air filter of low pressure loss and high efficiency, which has an electrostatic spinning nanofiber layer by an easy and inexpensive method. SOLUTION: In the method of manufacturing a filter medium for an air filter having an electrostatic spinning nanofiber layer, a nanofiber layer containing nanofibers having a nano-order fiber diameter is formed by spinning a polymer solution in which particles are distributed using an electrostatic spinning method on the surface of an air-permeable support layer. In the filter medium for the air filter, a PF value can be made≥15. COPYRIGHT: (C)2011,JPO&INPIT
