Development of tight protective clothing against noxious chemicals

主要结果如下：1)5名受试者中有4名在电动跑步机上步行40min，然后在30ﾟC和50%的温度下休息20min，前臂出汗率的增加幅度高于服装B(防水整理的棉质服装)。A型防护服的全身总出汗率也明显高于棉质防水整理防护服。结论：与尼龙湿涂层聚氨酯防护服相比，新型防水整理棉质防护服在主观表现力和减少热应变方面都有明显提高。2)在30ﾟ条件下，冷却上半身可以减少穿防护服者的生理应激。

Main results are summarized as follows :1) The increase of forearm sweat rate was higher in clothing A (nylon with wet coating polyurethane) than in clothing B (cotton with water repellent finish) in 4 out of 5 subjects walking on a motor-driven treadmill for 40 min, followed by 20 min rest at 30ﾟC and 50%. Total sweat rate of the whole body was also significantly larger in clothing A.It was concluded that the new cotton protective clothing with water proof finishing was improved in terms of subjective voting and reduction of heat strain compared with the protective clothing consisting of nylon with wet coating polyurethane.2) Cooling the upper torso could reduce the physiological strain in the working subjects wearing protective clothing at 30ﾟC.3) The boots materials are of importance in reducing physiological psychological strain under hot environmental conditions.
