FILTERING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a filtering material developing performances such as collecting efficiency of fine particle, pressure drop in good balance.

SOLUTION: The filtering material comprising a nonwoven cloth containing synthetic resin fiber and fibrillated lyocell fiber as essential components is characterized in that the ratio the fiber having the maximum frequency peak between 0.00 to 1.00 mm and having fiber length of 1.00 mm or more in a fiber length distribution histogram of the fibrillated lyocell fiber is 10% or more.
