The development of forestry worker's clothing with functions of mitigating severe climate.

1.研究了新材料电刷切割时衣物内部的气候变化。一种是棉和涤纶多层纱线的纺织，另一种是细旦腈纶的针织。它们不适合出太多汗。但它们在多云刮风或低湿度多风的晴朗天气条件下都能发挥其功能。2.上述服装包括棉织物和亚麻织物在人工气候箱中进行了测试。不同材料之间没有明显的差异。但也有人认为，间隙是必不可少的，需要开口来增加通风。3.研究了水冷背心在高温环境下的降温效果。衣服里的相对湿度增加了，但衣服里的温度被迫下降。水冷背心在工作和休息时都可以减慢心率。这对初学者来说尤其有效，尤其是在剪枝季节的早期，以及在休息日之后。4.冬季夹克是用棉和涤纶多层纱线织成的。他们有一个或两个缝隙，后面有紧固件。通过打开或合上缝隙来调节衣服内的湿度，保持皮肤和汗衫之间的夹层温度。5.利用非织造布纸开发出高吸汗性能的汗衫，并设计成穿着工人的衣服就可以脱掉。

1.Climate inside clothing of new materials when brush cutting was investigated. One was textile of yarn of multi-layrs of cotton and polyestel, and another was knitting of fine acrylic fiber. They could not be fitted to much sweating. But they would be able to display their functions in such conditions as cloudy and windy, or low humidity and windy fine weather.2.The above clothing including cotton and linen fabrics was tested in the artificial climate chamber. There could not be seen difference among materials. But it was suggested that the clearance was indispensable, and that openings were needed for increasing ventilation.3.Cooling effect of water-cooled vest was investigated in heat circumstances. The relative humidity inside clothing increased, but the temperature inside clothing was compelled to drop. The water-cooled vest could reduce the heart rate both when working and rest. It would be efficient espe-cially for beginners, early period of the brush-cutting season, and on after off days.4.Winter jackets were made using textile of yarn of multi-layrs of cotton and polyestel. They had one or two slits with fasteners in the back. They could adjust humidity inside clothing with keeping the temperature of the layr between the skin and the undershirt by opening or closing slits.5.Undershirts which had high performance of absorbing sweat were developed using nonwoven fabric paper, and they were designed to be removed with worker's clothing on.
