Abstract: This article introduced the automatic control system for the production of the antistatic agent for polyester tent fabrics,and described the principle of the hardware make-up and the programming of the software of the automatic control system.The antistatic property of the plastic coated polyester tent fabrics treated with the antistatic agent produced using automatic control was tested.It demonstrated through comparison and analysis that the antistatic property of the treated fabric has improved remarkably and that the automatic control system operates reliably.
