PROCESS FOR PRODUCTION OF FINELY FIBROUS CELLULOSE COMPOSITE PREPREG SHEET, PROCESS FOR PRODUCTION OF FINELY FIBROUS CELLULOSE COMPOSITE SHEET, AND PROCESS FOR PRODUCTION OF FINELY FIBROUS CELLULOSE COMPOSITE LAMINATE SHEET

摘要

The present invention relates to a method of producing a finely fibrous cellulose composite prepreg sheet, the method including a preparation step of mixing an emulsion of a reactive compound with an aqueous suspension containing a finely fibrous cellulose to prepare a mixed liquid, a papermaking step of dewatering the mixed liquid by filtration on a porous substrate to form a water-containing sheet, and a drying step of heating and drying the water-containing sheet; and a method of producing a finely fibrous cellulose composite sheet, the method including subjecting the finely fibrous cellulose composite prepreg sheet produced by the aforementioned production method to a curing treatment. The present invention is able to provide a method of producing a finely fibrous cellulose composite prepreg sheet with good efficiency, a method of producing a finely fibrous cellulose composite sheet, and a method of producing a finely fibrous cellulose composite laminate sheet.
