Abstract:
PROBLEM TO BE SOLVED: To provide: a laminated sheet which is an impervious sheet for wastes, can be joined without interfering with waterproofness, has high strength of the joined part to make it hard to peel off, and has moisture-permeable waterproofness; and a method for joining the laminated sheets.SOLUTION: Provided is a laminated sheet 1 comprising a sheet body 2 formed by laminating non-woven fiber sheets 11 comprising polyethylene terephthalate fiber on both surfaces of a moisture-permeable waterproof sheet 10 and a heat-fusible film 12 containing a substance having a lower melting point than the moisture-permeable waterproof sheet 10 and the non-woven fiber sheets 11. In the laminated sheet 1, at least one surface side of the non-woven sheet 11 is provided with mechanical interlacing treatment, the moisture-permeable waterproof sheet 10 has an exposed surface where the non-woven sheet 11 is not present on at least one surface thereof on at least one side of sheet body 2, the heat-fusible film 12 is present on the exposed surface of the moisture-permeable waterproof sheet 10, the heat-fusible film 12 is present on at least one surface of the non-woven sheet 11 on the one side of the sheet body 2, and the heat-fusible sheet 12 or the moisture-permeable waterproof sheet 10 is present on side surfaces of the non-woven sheet 11.SELECTED DRAWING: Figure 1
