THREE-DIMENSIONALLY SHAPED NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a nonwoven fabric having three-dimensionally uneven shape without using a specific production method, being flexible and having low basis weight. SOLUTION: The three-dimensionally shaped nonwoven fabric 10 has many pressed and bonded parts 25 in which the component fibers are pressed or thermally pressed and bonded and intersecting points of the component fibers are joined by a means other than thermal pressing in the parts other than these pressed and bonded parts 25 and the nonwoven fabric 10 has uneven shapes in which these pressed and bonded parts 25 become recessed parts 12 and parts between these recessed parts 12 become protruded parts 11 on at least either one surface. A thermally extensible fiber in which the length is extended by heating is used as the component fiber. COPYRIGHT: (C)2006,JPO&NCIPI
