The invention relates to a viscose monofilament production process. Cellulose fiber pulp is adopted as a raw material, and the steps such as spinning solution preparation, spinning, and post-treatment are carried out, such that the viscose monofilament is obtained. The method specifically comprises the process steps that: (A) cellulose fiber pulp is subjected to impregnation, aging, yellowing, dissolving, defoaming, and filtering, such that the spinning solution is prepared; (B) the spinning solution is delivered into a spinning machine, and passes through a spinning hole with a single-hole nozzle under pressure, such that viscose thin stream is formed, and raw filament strip is formed after coagulation molding, wherein jet nozzle stretch is +60% to +80%, and a spinning hole inlet pore channel is in a parabolic shape; and (C) post-treatment is carried out, wherein the raw filament strip is subjected to desulfurization, bleaching, oiling, and bake-drying, such that the viscose monofilament is obtained. With the production process provided by the invention, produced viscose monofilament has fineness of 50-6000D, and high strength higher than 75CN. With the viscose monofilament, requirements by dyeing, weaving and finished garments can be satisfied.
