ABSTRACT:
The present invention provides a nonwoven fabric of which at least one of fiber orientation, fiber density, and basis weight is adjusted, and in which at least one of a predetermined groove portion, an opening, and a protrusion is formed, a manufacturing method for the nonwoven fabric, and a nonwoven fabric manufacturing apparatus. The nonwoven fabric manufacturing apparatus of the present invention manufactures a nonwoven fabric of which at least one of fiber orientation, fiber density, and basis weight is adjusted, or in which at least one of a predetermined groove portion, an opening, and a protrusion is formed by blowing fluid mainly containing gas onto a fiber web which is formed in a sheet shape, and which is in a state where at least a portion of the fibers constituting the fiber aggregate has a degree of freedom.
