  • Nonwoven fabric and filter
    Patent number: 11491429
    Abstract: A nonwoven fabric, including fibers, in which the fibers have an elongational viscosity, as measured under conditions at an elongational strain rate of 2.5×102 (1/s) and a temperature of 160° C., of from 430 Pa·s to 1200 Pa·s, and a ratio of the elongational viscosity (Pa·s) to a shear viscosity (Pa·s) of the fiber, as measured under conditions at a shear strain rate of 2.5×102 (1/s) and a temperature of 160° C., is from 35 to 65.
    Type: Grant
    Filed: October 26, 2018
