Document Type and Number:
Japanese Patent JP7443071
Kind Code:
B2
Abstract:
To provide an extensible composite material which is free from being bulky in packaging or shipping, and can easily form a gather-like uneven structure having a good feeling on one surface or both surfaces due to extending operation at use.SOLUTION: An extensible composite material has a structure in which a boundary surface between a first base material A1 and a second base material 2 is connected by connection parts 3. The extensible composite material is such that: the first base material A1 is provided at one surface side of the second base material 2; the first base material A1 and the second base material 2 are extensible base materials; in an extension direction set to the extensible composite material, the permanent strain of the first base material A1 at 50% extension is 2.5-25%, and the permanent strain of the second base material 2 at 50% extension is 0-10%; the permanent strain of the first base material A1 is 2.5% or more larger than the permanent strain of the second base material 2; and the connection parts 3 are disposed at intervals in a pattern shape, and intervals between the connection parts 3 are non-connection parts 4.SELECTED DRAWING: Figure 1
