<p>A heat-bonding method for interior material includes heating one electrode of a high-frequency welder. The temperature to which the elctrode is heated is generally about 100 DEG C less than the melting point of the outermost interior finishing material. The increased temperature raises the susceptibility of the cushioning material to dielectric heating due to a high-frequency oscillating voltage from the high-frequency welder. There is also disclosed a method for selecting a urethane foam as a cushioning material which is optimal for use with the disclosed heat-bonding method, by determining the specific gravity and the air permeability rate of the urethane foam.</p> |
