Production method of washable electromagnetic shielding fabric

The invention provides a production method of washable electromagnetic shielding fabric. The production method comprises the following steps: (1), adding copper sulfate and a silver nitrate solution into water, then adding JFC and a dye-retarding agent, uniformly mixing, and adding sulfuric acid to adjust the PH value; (2), adding acrylic yarn or acrylic fabric into a prepared chemical reaction bath, adding a sodium thiosulfate solution, sodium sulfite and a sodium potassium tartrate solution, running in a container for 30min, then raising the temperature according to a temperature raising curve, preserving heat at 100 DEG C for 60min, reducing the temperature to 60 DEG C according to a temperature reducing rate of 1 DEG C/min, washing by using warm water, dewatering and drying; (3), coating the dried conductive acrylic yarn with graphene-based water-based electromagnetic shielding coating and weaving to obtain the washable electromagnetic shielding fabric, and coating the dried conductive acrylic fabric with
