医用防护服用非织造布的热湿舒适性能研究

Thermal Comfort Properties of Nonwovens Used in Medical Protective Clothing

测试了医用防护服用非织造布的结构特征参数,热湿舒适性方面的透湿透气性,以及KES测试的低负荷下各项力学性能等各项性能。分析了非织造布相较于传统医用服装机织面料在热湿舒适性、触觉舒适性及成型性等方面的特点。通过所设计的实验装置用DL-700C红外热像仪监测了模拟衣下微气候的热湿传递特性,以及不同状态时面料表面温度的变化规律。提出了织物表面温度变化率作为表征非织造布的热湿舒适性能的评价指标。

Thermal comfort properties of nonwovens used in medical protective clothing were studied in this study. Nonwovens characteristic of heat and moisture transmission, touching comfort, molding performance and so on were comparatively analyzed. A test apparatus were developed to simulate the heat and moisture transmission in microclimate under clothing. Using the apparatus fabric surface temperature was measured,and the relation to thermal comfort properties was summarized. A new index named as fabric surface temperature changing rate was proposed to indicate heat and moisture performance of nonwovens used in medical protective clothing.
