PURPOSE: A three layered padding without stick-through is provided to prevent hard touching of the padding by performing surface treatment without stick-through as well as surface reinforcement for preventing stick-through, and a manufacturing method of the three layered padding without stick-through is provided. CONSTITUTION: In manufacturing a three layered padding, the method for manufacturing the three layered padding without stick-through comprises a binder adhesion step adhering a binder which is composed in a certain mixing ratio onto the surface of a web(50) passing through heat press rolls using a sprayer; a drying step of first drying and crosslinking the surface of the web obtained in the binder adhesion step using a band drier, and second drying and crosslinking the binder adhered backside of the web after adhering a binder onto the backside of the web using a sprayer; a heating step of heating the dispersed powder using a far-infrared heater(62) after dispersing powder from a powder hopper(61) onto the upper part of an intermediate heat insulation layer one side of which is exudation prevention treated obtained in the drying step; and cooling step of completing lamination by passing the laminated material through a cooling roll(65) after laminating a thermally bonded non-woven fabric(63) on the upper part of the intermediate heat insulation layer passing through the heating step by means of thermoplastic powder using laminating rolls(64).
