<p><P>PROBLEM TO BE SOLVED: To provide a nonwoven fabric adjusted so that a prescribed fluid can quickly move. <P>SOLUTION: This nonwoven fabric is formed by blasting a fiber web 100 supported on a prescribed air-permeable support member from the lower side with a fluid consisting mainly of a gas from the upper side to move the fibers 101 constituting the fiber web 100. In the nonwoven fabric, groove portions 1 and convex portions 2 are formed in the extension direction of the blasted regions, and a fiber density in the groove portions 1 which are regions blasted with the gas is lower than that in the convex portions which are non-blasted regions not blasted with the fluid consisting mainly of the gas. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
