The invention relates to the technical field of textile production processes, in particular to a viscose producing process based on hemp pulp. The viscose producing process includes the following steps of firstly, preparing raw materials, wherein the hemp type raw materials are collected for use; secondly, preparing the hemp pulp, wherein the hemp type raw materials prepared in the first step aresubjected to enzyme cold piling, oxygen rinsing, washing and drying treatment to prepare the hemp pulp; thirdly, preparing viscose, wherein the hemp pulp prepared in the second step is subjected to pulverizing, sulfonating, dissolving, ripening, spinning, drafting, refining desulphurization and drying treatment to obtain the viscose. The production process is simple, mild in condition, environmentally friendly and capable of saving energy; the produced viscose is large in specific surface area, the dye-uptake and elongation at break of the fiber can be increased, the viscose is good in antibacterial property, the antibacterial property of the viscose can be kept to be 70-80% of that of original hemp, and the textile fabric is higher in drape factor and softer and more smooth in handfeel.
