摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a non-asbestos sheet having good incombustibility by a papermaking process though cellulose pulp and synthetic organic fibers are used together as a fiber raw material.
SOLUTION: The method is characterized in that a green film obtained from a raw material slurry by the papermaking process is wound around and superposed on a making roll through endless felt up to a disired thickness, and thereafter, this green film is taken out of the making roll to obtain a green sheet and a plurality of the obtained green sheets are laminated, molded under pressure and aged/cured. As the fiber raw material, cellulose pulp and synthetic organic fibers are together used and the green sheets are laminated so as to constitute both surfaces of a laminate by the surfaces not coming into contact with the making roll of the green sheets. The non-asbestos sheet obtained by the papermaking process is characterized in that the total heat value thereof at the time of 20-min heating using an ISO 5660 cone calorimeter is not more than 8 MJ/m
