Document Type and Number:
WIPO Patent Application WO/2024/066726
Kind Code:
A1
Abstract:
Provided in the present invention are a cellulose fiber regenerated from Juncao by means of an NMMO solvent method and a preparation method therefor. The preparation method comprises the steps of: (1) adding a DMSO/NMMO mixed solvent to Juncao pulp, simultaneously adding an antioxidant and cobalt chloride thereto, and mixing same until uniform, so as to obtain a mixed system; and (2) swelling and dissolving the mixed system to obtain a Juncao viscose solution, and filtering, defoaming and spinning the Juncao viscose solution to obtain a cellulose fiber regenerated from Juncao. In the present invention, Juncao pulp is used to replace traditional cotton pulp and wood pulp, and the existing dissolution conditions for regenerated cellulose fibers are innovated, such that the problem of insufficient raw materials for the production of cellulose fibers at present is effectively relieved, and the prepared cellulose fiber regenerated from Juncao can reach the standard of first-class products.
