PURPOSE:To obtain an agent impregnated material having a liquid agent uniformly permeated and impregnated into pore part of each impregnated material and void part between layers by capillary phenomena, by laminating materials of given shape to be impregnated and coating each visible face with the liquid agent by spray. CONSTITUTION:Materials (e.g. rectangular mat for repelling mosquitoes) 1 of given shape to be impregnated are made into a piled state, a spray nozzle 3 is moved in the arrow direction above the materials or each mat is transferred based on a fixed spray nozzle and a liquid agent is sprayed from the spray nozzle 3 to give an agent impregnated material. By this method, the liquid agent is uniformly impregnated into each material and there is no problem of ununiformity between outside and inside which is found in an impregnated material wherein a beltlike material is wound in a cylindrical state. An insecticidal germicide, perfume or deodorant is used as the liquid agent and the liquid agent may contain a synergist, antioxidant, pigment, dyestuff, extender or thickening agent. The above-mentioned method has high productivity since a large amount of the agent impregnated material of any shape in a facial state can be continuously treated.
