Document Type and Number:
WIPO Patent Application WO/2022/158412
Kind Code:
A1
Abstract:
The present invention addresses the problem of obtaining: a substrate for a filter in which pressure loss does not readily increase when affixed through thermal fusion, and in which high peel strength is obtained between a porous film and the substrate for a filter; and a filtration material for a filter in which the substrate for a filter is used. The present invention is a substrate for a filter to be used as a filtration material for a filter in which a porous film is affixed by thermal fusion, wherein the substrate for a filter is a wet non-woven fabric including non-binder fibers (NB) and thermally fusible binder fibers (B). The present invention is also a filtration material for a filter in which the aforementioned substrate for a filter is used.
