The invention discloses a preparation method for cold silks. The preparation method comprises the following steps: preparing a mucilage glue stock solution; preparing a cold mucilage glue stock solution and adding a cold storage agent; treating before spinning and injecting dispersing agent; spinning, weaving and thus obtaining the final cold silks. According to the method, the physical mixing mode of adding auxiliaries is adopted, so that the chemical structure of the viscose is not changed and the effect of the frozen silk in the market is achieved; the technique is simple; the main production technique of the current conventional viscose is not changed; the pipeline mixing and injection method is adopted, so that the preparation of the easily cooling mucilage glue stock solution is realized and the investment is less; the productivity is high; the cold silk product can increase the living quality of people and also can meet the market requirement.
