Biomass fungus grass regenerated cellulose fiber and preparation method thereof

The invention provides a biomass pennisetum hydridum regenerated cellulose fiber and a preparation method thereof, the preparation method comprises the following steps: dipping, squeezing, aging, yellowing, dissolving, filtering, defoaming and spinning, and a catalyst and a dipping auxiliary agent are added into a dipping solution in the dipping process; traditional cotton pulp and wood pulp are replaced by the Juncao pulp, existing regenerated cellulose fiber production equipment and process are innovated, the preparation method of the biomass Juncao regenerated cellulose fiber is established, the used Juncao raw materials are high in yield and low in price, the production process of the Juncao pulp is green and environmentally friendly, and the production cost is low. The problem that existing cellulose fiber production raw materials are insufficient can be effectively relieved. Meanwhile, after the existing cellulose fiber production equipment is innovated, the mass production of the Juncao cellulose fiber
