The invention relates to a production process of a hot-molten non-woven fabric electrostatic fiber filter screen, and belongs to the technical field of new material processing. The production process comprises the following steps of firstly, fiber unpacking and mixing, secondly, carding, thirdly, web forming, fourthly, compounding, fifthly, hot melting bonding, sixthly, cooling and seventhly, edge cutting, winding and packaging. According to the production process, the hot-molten non-woven fabric electrostatic fiber filter screen can be obtained without adopting an electret technology. Odorless electrostatic adsorbed polypropylene fibers are adopted as raw materials, a hot-molten non-woven fabric production process method is utilized, in the carding process, electrostatic rods with the polarity opposite to that of the odorless electrostatic adsorbed polypropylene short fibers are arranged in front of a carding machine, meanwhile, a humidifier is mounted below the carding machine, and it is guaranteed that relative humidity in the carding process is 60% or above; and under the combined action of the electrostatic rods and the humidifier, electrostatic fibers overcome the electrostatic fiber bonding phenomenon in the carding process, and the hot-molten non-woven fabric electrostatic fiber filter screen is manufactured.
