Clothing Hygienic Study of Protective Coveralls

本研究旨在阐明防护服的小气候和生理效应。测试了四种防护服（石棉消除工作防护服、化学防护服、农用化学品防护服和隔热服），获得的结果如下。1.在25-27 ℃的最佳降温工作环境中，生理性劳损不严重，但在2-3 ℃的高温环境中，心率为140-170次/分，肛温升高约40 ℃。患热病的风险很高。2.从气候室穿着试验结果来看，防护服的微气候变得湿热，非常不舒适。3.为改善防护服的微气候，对织物结构、纺织性能和运动功能进行了研究。从提高运动效率的角度看，防护服应增加长度方向的舒适度。4.从农药防护服的穿着试验结果来看，使用罩式鼓风机显示出良好的生理反应。5.设计了一种用于防化服，特别是防酸服织物评价的装置，该装置可用于防化服织物的筛选。

This study was carried out to clarify the microclimate and physiological effect of protective clothing. Four protective clothings (Protective Coveralls for Asbest abatement work, Chemical Protective Clothing, Protective Clothing for Agricultural Chemicals and Thermal insulative Clothing) were tested.Results obtained were as follows. 1. At the asbest abatement work in 25-27ﾟC,physiological strains were not so severe,but at the work in 2-3ﾟc higher environment,heart- rate counted 140-170 beat/min and rectal temperature rose about 40ﾟc. There was a high risk of suffering from heat illness. 2. From the results of wearing tests in climate room,microclimate of protective clothing became hot and humid, so it was very uncomfortable condition. 3. To improve the microclimate of protective clothing,the structure of fabrics, he textile properties and motional function of protective clothing were studied. From the view point of improvement of motional efficiency, protective clothing were necessary more amount of ease of length direction. 4. From a result of wearing test of protective clothing for agricultural chemicals, use of hood type blower showed good physiological responses. 5. An apparatus for a fabric evaluation of chemical protective clothing,especially acid protective clothing was designed.This apparatus was useful for screening of fabrics for chemical protective clothing.
