  • Publication number: 20220212451
    Abstract: A problem to be solved by the invention is to provide a stretchable laminate achieving both of excellent elongation and an excellent breaking strength, and a method of manufacturing the laminate. A stretchable laminate of the present invention includes non-woven fabric layers and an elastomer layer. The non-woven fabric layers are each a long-fiber hydroentangled non-woven fabric. The stretchable laminate achieving both of excellent elongation and an excellent breaking strength is obtained by using the long-fiber hydroentangled non-woven fabric, which is a non-woven fabric formed through the fixation of fibers formed by a spun-laid method by a hydroentangling method.
