The invention relates to a preparation method of viscose fibers, which belongs to the technical field of textiles. The preparation method comprises the following steps: heating pulp and an alkaline solution to facilitate the reaction, filtering to obtain filter residues, pressing and crushing the filter residues to obtain a crushed matter, heating the crushed matter and a sodium periodate solution to facilitate the reaction, filtering to obtain a filter cake, mixing the filter cake, the ethyl methacrylate and water, adding an initiator, centrifugally separating after the reaction, obtaining precipitates, heating and stirring the precipitates, a sodium hydroxide solution, sodium sulfite and carbon disulfide to facilitate the reaction, adding natural rubber and spider silk, stirring, mixing, then filtering to obtain filtrate, ultrasonically dispersing, standing and defoaming the filtrate to obtain a spinning stock solution, spinning stretching and after-processing the spinning stock solution, and obtaining the
