Document Type and Number:
WIPO Patent Application WO/2023/048309
Kind Code:
A1
Abstract:
Disclosed are a method for dissociating and extracting a cellulose raw material, comprising: a first step of mixing a cellulose raw material and a swelling agent so as to swell the cellulose raw material; a second step of adding a sublimable material to the swollen cellulose raw material; a third step of irradiating electron beams to the cellulose raw material to which the sublimable material has been added; and a fourth step of nanobubbling the raw material to which the electron beams have been irradiated, a method for producing a cellulose microfiber comprising the method for dissociating and extracting the cellulose raw material, a cellulose microfiber produced according to the method for producing a cellulose microfiber, and an apparatus for manufacturing a cellulose microfiber in which the method for producing a cellulose microfiber can be performed. The method for producing a cellulose microfiber of the present invention has advantages in terms of production cost and performance conditions.
