Abstract
The present invention provides a method for easily and efficiently manufacturing microfibrous cellulose composite sheets. The present invention is a method for manufacturing microfibrous cellulose composite sheets, including a preparation process in which a polymer emulsion is mixed with an aqueous suspension including microfibrous cellulose, thereby preparing a mixed fluid, a papermaking process in which the mixed fluid is dehydrated on a porous base material through filtration, and a sheet including moisture is formed, and a drying process in which the sheet including moisture is heated and dried. In addition, the present invention is a method for manufacturing a microfibrous cellulose composite sheet laminate, in which the microfibrous cellulose sheets are thermally compressed and thus laminated as they are or after being provided with a polymer layer on at least one surface thereof.
