Abstract (en)
[origin: EP1323857A2] A method for manufacturing a three-dimensional non-woven fabric according to the invention is a method in which semi-molten fibers are spun on a forming surface of a mold to form the three-dimensional non-woven fabric. The method includes a step of preparing a plurality of mold pieces (12, 15), which can be mutually overlapped and a step of forming a mold (10) including forming surfaces (13, 14, 16, 17) in a certain size by partly mutually overlapping a plurality of the mold pieces (12, 15) and adjusting the area in which the mold pieces are mutually overlapped. This makes it possible to form plural types of three-dimensional non-woven fabrics whose sizes are different using only one unit of mold (10). <IMAGE>
