Electrically charged nonwoven fabric, filtration material using same, and method for producing electrically charged nonwoven fabric |
| abstract |
A novel filter medium having excellent heat resistance and flame retardancy, which is improved in performance compared with the conventional one, and an electrified nonwoven fabric to be used therefrom are provided by the electrification nonwoven fabric formed by using a fiber composed mainly of an amorphous polymer. Preferably, the surface charge density is 1 x 10 < -10 > Coulomb / cm < 2 > The desorption efficiency of the dust having a particle size of 1 mu m at a surface velocity of 8.6 cm / sec is preferably 40% or more, the QF value is 0.05 or more, and the reduction rate of the dust collecting efficiency after being left at 100 DEG C for 24 hours Is less than 10%. The present invention further provides a method for producing a filter material and a charging nonwoven fabric using such a charging nonwoven fabric. |
