NONWOVEN FABRIC PRODUCTION METHOD

WIPO Patent Application WO/2020/189170

A1

Provided is a nonwoven fabric production method capable of producing nonwoven fabric wherein hole diameters change from one edge to the other edge without boundaries.　A nonwoven fabric production apparatus (10) applies voltage between a collector (52) and nozzles (25a) and jets a solution (23a) from the nozzles (25a) toward the collector (52) to form fibers (11). The formed fibers (11) are collected on the collector (52) to form a nonwoven fabric (20). The nonwoven fabric production apparatus (10) is provided with a static eliminator (28). The static eliminator (28) eliminates static electricity of the nonwoven fabric (20) so that if the basis weight of the nonwoven fabric (20) is W (g/m2) and the charge is v (kV), "0. 03
