Improvement of function and comfortableness of forestry-workers' clothing

对采伐现场夏季衣物内气候进行了调查。胸部和腹部气候的个体差异得到了认识。背部紧闭，受到直射光线的影响。在此基础上，以棉花和亚麻为原料，制作了4种毛剪衬衫。并且认识到生理负荷可以从以下几个方面得到改善。(1)颈部大张开，胸部皮肤温度保持低水平稳定。(2)在炎热的天气下努力工作时，无论材质和设计，衣服的湿度都达到100%，这是一种感觉。亚麻衬衫穿起来很舒服，因为它比棉质衬衫更不容易粘在肩膀上。对雨衣内部的气候也进行了研究。普通的氯乙烯雨衣不通风，不散热，即使在17-18℃的温度下也会觉得冷，因为出汗变冷了。另一方面，斯堪的纳维亚森林工人的雨衣感觉不到冷，因为适度的通风不会使汗水变冷，从而保持温暖。但是当温度降到12℃的时候，感觉很冷。冬季下雨或放草作业时，衣物内温度为30-31℃。因此，根据季节和天气的不同，人们会感到温暖或寒冷。该值对户外工作者的冬季服装设计有一定的指导意义。

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.
