On standpoint of home-making education, a convenient measuring method of the heat transmission of cloths is examined. It is difficult for teachers to explain well the term of the heat transmission of cloths for their students. However, it will become easier for teachers to make students understand the concept of heat transmission if teachers adopt some visual experiment. There are many devices such as ASTM method, thermo-labo method, and others, to measure the thermal insulation and the heat transmission of cloths. However these are not only expensive but also difficult to operate them, and seem to be unsuitable as teaching materials. On these reasons, a method comparable easily on the difference of heat transmission values of cloths by using an automatically controlled electric iron and some heat sensitive papers for word processors was devised and established. By this method, the heat transmission phenomena can be obtained not on the form of its absolute value but on one of sample direct difference which can be confirmed and compared by the observer's eyes. Moreover, this device is thought to be an extremely effective means for the visual teaching materials because of its performance with the iron and the heat sensitive papers only.
