Document Type and Number:
Japanese Patent JP2011000520
Kind Code:
A
Abstract:

To provide a frictional electrification filter medium which can attain its long service life in addition to low pressure loss and high particle capturing efficiency.

This frictional electrification filter medium can be obtained by frictionally electrifying a fibrous mixed layer containing (i) and (ii) fibers which account for 65 to 85 mass% and 35 to 15 mass% respectively. (i) The fine fiber includes a polyolefin-based fiber with a fiber diameter of 10 to 20 μm and a polyester-based fiber with a fiber diameter of 10 to 20 μm in the mass ratio of 30:70 to 70:30, and (ii) the gross fiber has a fiber diameter of 20 to 40 μm.
