Improvement of function and comfortableness of forestry-workers' clothing

本文对夏季灌丛采伐迹地的衣内气候进行了调查。胸部和腹部气候的个体差异得到了承认。而且后背紧闭，受到直射光线的影响。在此基础上，以棉、麻为原料制作了四种割灌衣。并且认识到生理负荷可以如下改善。(1)通过颈部大开，胸部皮肤温度保持在较低水平，并保持稳定。(2)在炎热的天气下辛勤工作时，衣服的湿度达到100%，无论材料和设计如何，这成为一种感觉。亚麻衬衫比棉衬衫更不容易与肩部皮肤粘连，因此穿着舒适。氯乙烯雨衣不通风，不散热，即使在17-18摄氏度时也会感到寒冷，因为汗水会变冷。另一方面，斯堪的纳维亚森林工人的雨衣并不冷，因为适度的通风不会使汗水变冷，所以它保持温暖。但当气温下降到12摄氏度时，人们会感到寒冷。冬季下雨或进行集材作业时，衣服内的温度为30-31摄氏度。所以，根据季节和天气，感觉温暖或寒冷。该值对野外作业人员冬季服装设计具有一定的参考价值。

The climate inside clothing in summer on brush cutting sites was investigated. Individual differences in the climate of the chest and the abdomen were recognized. And the back was shut tightly and was affected by the direct rays. Four kinds of shirts for brush cutting were made from cotton and flax based on the above results. And it was recognized that the physiological load could be improved as follows.(1) By the neck wide open, the temperature of the chest skin were kept in low level and was stable.(2) When working hard under the hot weather, the humidity in clothing reached at 100% irrespective of materials and designs, and it became a matter of feeling. A flaxn shirt was comfortable because it adhered to the shoulder skin less than cotton shirts.The climate inside raincoats was also investigated. Usual raincoat of vinyl chloride had no ventilation and did not radiate heat, and was felt cold even when 17-18ﾟC because the sweat got cold. On the other hand, a Scandinavian forest-worker's raincoat did not felt cold because the sweat did not so get cold by moderate ventilation that it kept warmth. But it was felt cold when the temperature went down to 12ﾟC.The temperature inside clothing was 30-31ﾟC when rainy or yarding operations in winter. So, it was felt warm or cold according to the season and the weather. This value will be helpful in designing outdoor-workers' winter-clothing.
