Title:
積層体及びその製造方法
Document Type and Number:
Japanese Patent JP6748420
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate which is flexible, is excellent in air permeability, and reduces a load on the environment.SOLUTION: A laminate has a laminated structure formed by directly joining a first substrate and a second substrate that have different kinds and have sheet shapes, the first substrate is a film mainly containing a thermoplastic resin or a nonwoven fabric, and the second substrate is a fiber assembly mainly containing a cellulose-based resin. A method for manufacturing a laminate includes: an atomospheric plasma treatment step of subjecting one surface of a rolled sheet for a first substrate to atomospheric plasma treatment of bringing atomospheric plasma generated by a plasma device using gas for treatment under atomospheric pressure into contact with the one surface; and an integration step of overlapping a rolled sheet for a second substrate on one surface of the rolled sheet for the first substrate subjected to the atomospheric plasma treatment, heating and pressurizing the overlapped body, and integrating both of the sheets.SELECTED DRAWING: None
