Method for producing simple nonwoven fabric having unevenness and method for simple processing of nonwoven fabric

摘要

It is an object of the invention to provide a method of easy production of a nonwoven fabric having at least one projection and at least one recess and to a method of easy processing of a nonwoven fabric. A method of producing a nonwoven fabric having at least one projection and at least one recess, comprising the steps of non-homogeneous stretching a nonwoven fabric so as to form a nonwoven fabric with high-stretch regions and low-stretch regions, and forming a nonwoven fabric having at least one projection and at least one recess by placing the nonwoven fabric with high-stretch regions and low-stretch regions on a support and spraying a fluid onto the nonwoven fabric with high-stretch regions and low-stretch regions for treatment.
