Numerical Estimation of the Thermal Response of Thermal Protective Clothing-Air Gap-Human Skin Micro-system

Thermal protective clothing has been recognized as the primary shielding against emergency fire hazard and inflammable gas leakage. Therefore,the thermal response of human covered with thermal protective clothing under high temperature is the key work to investigate the thermal insulation of thermal protective clothing. A coupling model composed of thermal protective clothing,air gap and human skin is established and the temperature of the micro-system is numerically solved via the finite element method( FEM).Especially,the heat transfer of air gap located between clothing and human skin considering conduction and radiation is established while the human skin layers involve the effect of blood perfusion. Then the effect of thermophysical properties( thermal conductivity and volumetric capacity) of fabric and thickness of fabric and air on the thermal response of the micro-system is elucidated and compared.The results indicate that the volumetric heat capacity of fabric is the key parameter to affect the thermal shielding performance of thermal protective clothing,and the thicker fabric thickness and air gap thickness can improve the thermal protective properties of the micro-system.

服装开口部位对着装热舒适性的影响

服装开口是促进衣下空间与外界环境之间热交换的重要途径.采用暖体假人和人体生理试验方法,在无风和有风两种条件下,对胸部、背部和腋下等不同部位开口及无开口状态下的服装热阻、平均皮肤温度、衣下湿度和主观舒适感等指标进行测量.研究结果显示,服装开口部位对服装总热阻有影响,腋下开口的服装热阻最低;服装开口部位对人体体温调节有显著影响,在胸部和腋下开口有助于增强衣下空气与外界环境之间气体交换,增加对流和蒸发散热,从而减缓皮肤温度和衣下湿度升高.试验结果同时表明,风速对服装热阻及人体各项生理指标的影响更为显著.总体而言,服装腋下部位开口对人体热湿生理调节起到促进作用,具有较好着装舒适感.

Clothes Keypoints Detection with Cascaded Pyramid Network

With the development of the society, people's requirements for clothing matching are constantly increasing when developing clothing recommendation system. This requires that the algorithm for understanding the clothing images should be sufficiently efficient and robust. Therefore, we detect the keypoints in clothing accurately to capture the details of clothing images. Since the joint points of the garment are similar to those of the human body, this paper utilizes a kind of deep neural network called cascaded pyramid network(CPN) about estimating the posture of human body to solve the problem of keypoints detection in clothing. In this paper, we first introduce the structure and characteristic of this neural network when detecting keypoints. Then we evaluate the results of the experiments and verify effectiveness of detecting keypoints of clothing with CPN, with normalized error about 5%-7%. Finally, we analyze the influence of different backbones when detecting keypoints in this network.

环境色彩对着装温度舒适性的影响

环境、服装、人体是一个统一系统，环境中温湿度以及其他物理指标的变化对人体着装舒适性产生显著影响。讨论环境色彩的改变对人体着装温度舒适性的影响，从而为舒适的环境色彩设计提供理论依据。采用试验方法，在人工气候室内进行人体主观评价和客观生理量测试，并对所获得的数据进行统计分析。通过数据分析认为环境色彩的改变对着装温度舒适性产生影响，并引起皮肤温度的波动从而影响着装温度舒适性，同时环境色彩的变化刺激人体神经系统从而影响舒适感觉，但在正常环境下这个影响因素为非主要影响因子，因此，在正常环境中可以通过调节环境色彩来改变和提高人体着装温度舒适性。
