1. A production method for a nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite comprising:

dispersing a bacterial cellulose hydrogel in water to obtain a uniformly dispersed bacterial cellulose microfibril aqueous solution;

adding sodium alginate and zinc salt to the bacterial cellulose microfibril aqueous solution, and then subjecting to a heating treatment, to obtain a nano-zinc oxide-supported bacterial cellulose microfibril aqueous solution; and

immersing an alginate fiber spunlace non-woven fabric into the nano-zinc oxide-supported bacterial cellulose microfibril aqueous solution, and then freeze-drying, to obtain the nano-zinc oxide-supported bacterial cellulose microfiber-alginate fiber composite.
