Title:
NONWOVEN FABRIC, METHOD FOR MANUFACTURING NONWOVEN FABRIC, AND LIQUID FILTER
Document Type and Number:
WIPO Patent Application WO/2022/054378
Kind Code:
A1
Abstract:
A nonwoven fabric having high filtration performance, a method for manufacturing said nonwoven fabric, and a liquid filter are provided. At a nonwoven fabric manufacturing facility (15), a fiber (11) formed by applying a voltage between a solution (23a) and a collector (52) and jetting out the solution (23a) through a nozzle (25a) is captured by the collector (52) to acquire a nonwoven fabric (10). The solution (23a) contains a heat-cured material (18), and the heat-cured material (18) is cured in a heating section (40). When the thickness of the manufactured nonwoven fabric (10) is H30 when a pressure of 30 kPa is applied and the thickness when no load is applied is H0, H30/H0 is greater than 0.1 and within the range of 0.5 or less.
