Title:
METHOD FOR MANUFACTURING NANOCELLULOSE FIBER HAVING LONG FIBER LENGTH BY USING ECO-FRIENDLY ELECTRON RAY PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/194378
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a nanocellulose fiber by using an eco-friendly process, comprising the steps of: (step 1) manufacturing pulp from wood or non-wood, which is a material; (step 2) irradiating, with electron rays, the pulp obtained in step 1; and (step 3) separating and obtaining nanocellulose by grinding the electron ray-irradiated pulp of step 2. In addition, the present invention provides, in order to obtain a nanocellulose fiber by means of electron ray emission without using a strong acid, a method for manufacturing a nanocellulose fiber having a long fiber length by using an electron ray process, the method compensating for the disadvantages of a chemical separation method and a physical separation method, and maximizing yield by means of an effective method while minimizing environmental pollution.
