BASE FABRIC FOR FILTRATION

摘要

PROBLEM TO BE SOLVED: To provide a base fabric for filtration that sufficiently suppresses deterioration of mechanical strength of a base fabric while securing desired metal ion adsorption capability.SOLUTION: A base fabric for filtration is structured by a nonwoven fabric and has metal ion adsorption capability. In the base fabric for filtration, there is a difference between adsorption capacity of one surface side and adsorption capacity of the other surface side. The base fabric for filtration has 2 N or higher tensile strength and 5% or higher tensile elongation.
