Title:
METHOD FOR MANUFACTURING HIGH-STRENGTH NANOCELLULOSE LONG FIBER THROUGH STEAM TREATMENT AND EXTRUSION
Document Type and Number:
WIPO Patent Application WO/2020/022532
Kind Code:
A1
Abstract:
The present invention can provide a high-strength nanocellulose long fiber, which has extrusion stability such that the nanocellulose long fiber is extruded in a state in which nanocellulose is homogeneously dissolved and combined with an extruded long fiber even without addition of a separate chemical substance, through an inter-nanocellulose covalent bond increasing effect obtained due to saturated steam and a predetermined pressure and temperature by steaming a nanocellulose ointment material in which a nanocellulose powder is mixed with ultrapure water.
