Title:
ACTIVE CARBON FIBER NON-WOVEN FABRIC, AND ELEMENT USING SAID NON-WOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2013/081049
Kind Code:
A1
Abstract:
The present invention provides an active carbon fiber non-woven fabric which is formed using a fiber having a fiber diameter enough to reduce the pressure loss of an element, and has tensile strength at such a degree that the non-woven fabric cannot be broken even when wrapped strongly around a cylinder. The active carbon fiber non-woven fabric according to the present invention is produced by subjecting a phenolic fiber to a non-woven fabric processing procedure and then carbonizing and activating the resultant product, wherein the phenolic fiber is produced by spinning a mixture prepared by mixing a phenolic resin with at least one compound selected from the group consisting of a fatty acid amide, a phosphoric acid ester and a cellulose and then curing the spun product, said non-woven fabric being characterized in that an active carbon fiber that constitutes the non-woven fabric has a fiber diameter of 21 to 40 μm and a toluene adsorption rate of 20 to 75% and the tensile strength of the non-woven fabric is 4 N/cm2 or more.
