Dry-laid nonwoven fabric production method

Abstract

A dry-laid nonwoven fabric production method may include: affixing resin particles including polymeric molecules to a plurality of first fibers; applying an external force to the plurality of first fibers to which the plurality of resin particles are affixed so as to reduce gaps between the first fibers; relieving the applied external force to form in gas, from the plurality of resin particles, second fibers each having an outer diameter smaller than that of the first fiber and the outer diameter of each of the second fibers have a value in a range from 30 nm to 1.0 μm; and forming a nonwoven fabric that is a fiber composite including the first fibers and the second fibers.
