Title:
BIOMASS JUNCAO REGENERATED CELLULOSE FIBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/017399
Kind Code:
A1
Abstract:
Provided in the present invention are a biomass Juncao regenerated cellulose fiber and a preparation method therefor. The preparation method comprises: impregnation, pressing, aging, etiolation, dissolving, filtering, defoaming and spinning processes. A catalyst and an impregnation aid are added into an impregnation liquid in the impregnation process. In the present invention, a Juncao pulp is used to replace the traditionally used cotton pulp and wooden pulp, so as to innovate the traditional regenerated cellulose fiber production device and process, and a preparation method of the biomass Juncao regenerated cellulose fiber is established. The Juncao raw material used is high in yield and low in price, and the production process of the Juncao pulp is environment-friendly, thereby effectively relieving the problem of existing cellulose fiber production raw materials being insufficient. Meanwhile, after innovating the existing cellulose fiber production device, mass production of the Juncao cellulose fiber can be achieved, so that production cost is saved, and production requirements of textile enterprises are met.
