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

A method of producing a finely fibrous cellulose composite prepreg sheet, sheet or laminate sheet, the method including a mixing an emulsion of a reactive compound with an aqueous suspension containing a finely fibrous cellulose to prepare a mixed liquid dewatering the mixed liquid by filtration on a porous substrate to form a water-containing sheet; and heating and drying the water-containing sheet. A method of producing a finely fibrous cellulose composite sheet, the method including subjecting the finely fibrous cellulose composite prepreg sheet produced by the method described above to a curing treatment.
