Document Type and Number:
Japanese Patent JP6727531
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a dry solid article of a cellulose nanofiber having properties that change in physical properties such as viscosity and transparency of a cellulose nanofiber dispersion, where the dry solid article of the cellulose nanofiber by drying a stably dispersed cellulose nanofiber dispersion is redispersed, is less compared to the cellulose nanofiber dispersion before drying (redispersion property).SOLUTION: There is provided a manufacturing method of dry solid article of a cellular nanofiber including adjusting an aqueous suspension for the cellular nanofiber to pH of 9 to 11 and dehydrating and drying it.SELECTED DRAWING: None
