Abstract
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, which can be mutually overlapped and a step of forming a mold including forming surfaces in a certain size by partly mutually overlapping a plurality of the mold pieces 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.
Claims10
A method for manufacturing a three-dimensional non-woven fabric in which semi-molten fibers are spun onto a forming surface of a mold to form the three dimensional non-woven fabric, comprising
- preparing at least two mold pieces including a first mold piece, and a second mold piece which can be mutually overlapped with the first mold piece and whose area mutually overlapping with the first mold piece is adjustable, and
- forming a mold including a forming surface in an desired size by partly mutually overlapping the first mold piece with the second mold piece and adjusting the area in which the two mold pieces are mutually overlapped.
A mold used for a method for manufacturing a three-dimensional non-woven fabric in which semi-molten fibers are spun on a forming surface of a mold to form the three dimensional non-woven fabric, comprising at least
- a first mold piece, and
- a second mold piece which can be mutually overlapped with the first mold piece and whose area mutually overlapped with the first mold piece is adjustable.
