How to select comfortable dressings with seasons in the course of Industrial Arts and Home Economics at Junior High School was summarized in a 15 minutes video tape as a teaching material. One of the reasons we took the video tape is to help students to easily get a better understanding of the content by eye, and the other is to support teachers to effectively teach the content to their students in a classroom. This video tape showed comparison of comfortable dressings on fabrics commponents (Cotton 100%, Linen 100% and PET/Cotton＝65/35), two types of design (an open collar shirt and a shirt collar shirt) and color (black, blue, green, red, yellow and white).
The results shown in the video tape were as follows :
1. Elevated ratio of skin temperatures in thermogram at 30 minutes after walking was highest with PET/Cotton among the fabrics components, then Cotton and Linen was lowest.
2. Skin temperature with a shirt collar shirt design was higher than an open collar design in thermograms at 30 minutes after walking.
3. Dressings with deep colors such as black, blue, green and red led to higher skin temperature than the one with weak colors such as yellow and white, because of absorption efficiency of radiant heat. Temperature difference in two color types of dressings under sun light was bigger than under fluorescent light.
In conclusion a suitable and comfortable dressing in summer time was composed of fabric made by Linen and Cotton, design with less covering area and breathable property like an open shirt, and weak colors.
