智能发热户外防寒服装研制与性能评价

摘要

The composition of clothing can affect its thermal performance.According to the requirements of protection against the outdoor cold environment,a piece of novel multi-layer cold protective clothing was developed,including waterproof jacket,fleece and pants.Meanwhile,a smart electrical heating element was applied to improve the thermal performance of cold protective clothing.Evaluations of the thermal properties of clothing were performed by thermal manikin tests in constant temperature mode and human trial tests under two conditions (heating and non-heating).The effects of two wind speeds (0.4 and 1.5 m/s) on the protective performance of cold protective clothing were also discussed.The cold protective performance of the developed smart heating outdoor clothing was assessed by the changes in skin temperature and psychological perception as well.The research findings will provide technical basis and guideline for the design and optimization of cold protective clothing in cold environments.%服装的构成方式会对其防寒性能产生影响.根据户外冷环境的防护要求,研制了新型的多层户外防寒服套装,包括防水外套、抓绒内胆、防寒裤,采用智能电加热装置提高户外防寒服装的调温性能.通过暖体假人试验和真人试验分别评价防寒服装在两种状态下(加热和不加热)的保暖性能.暖体假人试验还探讨了两种风速(0.4和1.5 m/s)对户外防寒服的冷防护性能的影响,结合真人试验表征的皮肤温度变化以及主观感受,从而评价所研制的智能发热户外服装的防寒性能.研究结果将为优化户外防寒服的设计提供科学依据.
