Title:
NONWOVEN FABRIC AND METHOD FOR MANUFACTURING NONWOVEN FABRIC
Document Type and Number:
WIPO Patent Application WO/2021/199717
Kind Code:
A1
Abstract:
Provided are a nonwoven fabric of a large basis weight, and a method for manufacturing the nonwoven fabric. 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 electrical conductivity of the solution (23a) is within a range of more than 2 mS/m but less than 50 mS/m. A conductive liquid (31a) is adhered to the fiber (11). The manufactured nonwoven fabric (10) has an average fiber diameter within a range of 10 nm-2000 nm, a porosity of 90% or higher, and a basis weight within a range of 120-2000 g/m2.
