The protection of a human body against the negative environmental factors, especially the cold, is one of the crucial functions of clothing. Clothing creates a thermal barrier between the human body and the surroundings. The protective efficiency of clothing goods depends mostly on thermal insulation properties of textile materials applied in clothing. The clothing design, fitting to a user’s body, and a number of layers also play an important role in the phenomenon of the heat exchange between the human organism and its surroundings. The thermal insulation properties of textile materials can be measured by means of different testing devices, such as the “skin model,” the Alambeta, the Permetest, and the Thermo Labo. A measurement of clothing goods from the point of view of their thermal insulation is performed using a thermal manikin. The article presents an investigation of thermal insulation properties of vests by means of thermal manikin. The investigated vests have been made of different textile materials: woven and knitted. The thermal insulation properties of fabrics applied in vests have been measured by means of the Alambeta. The article presents and discusses the relationships between the thermal insulation of vests according to the thermal manikin and the thermal resistance of fabrics applied in the vests. 相似文献

The heat transport properties observed in nanostructured materials such as aerogel-treated nonwoven fabrics are promoting revolutionary breakthroughs as thermal insulators. This article is focused on the thermal transport characteristics of nonwoven fabrics treated with aerogel for potential uses in thermal protective applications. Highly efficient aerogel thermal blankets are now considered a viable option in applications such as clothing, building, and pipelines. A variety of fiber and fabric structures or finishing parameters influence the functional properties of nonwoven materials. In order to assess the thermal properties of aerogel-treated nonwoven fabrics, the KES Thermolabo II and NT-H1 (plate/fabric/plate method for thermal conductivity, qmax cool/warm feeling, and thermal insulation) was used. Fabrics of higher thicknesses show lower heat conductance and therefore higher thermal insulation properties. It has been found that thermal insulation is also related to the weight and compressional properties of the fabric. To make an insulating material effective, it should have low compression set and high resiliency to make the still air to be entrapped into the fibrous material. 相似文献

为实现防寒服保暖性能的动态调节,研发了以空气为保暖材料的Mountain充气夹克,采用外置手动按压充气泵连续改变充气量及其保暖性能。基于暖体假人实验,在不同充气量、有无袖子、是否穿抓绒衣3种实验条件下测试了充气夹克的局部热阻和总热阻,对比了NuDown充气夹克的隔热性能。实验结果表明:充气状态下的局部热阻和总热阻明显高于未充气状态,充气量会显著影响热阻,充气量越大服装热阻越高,且Moutain充气夹克在充气状态下比NuDown充气夹克具有更佳的保暖调节能力;有袖子时的局部热阻和总热阻明显高于无袖子状态,腹部和背部表现尤为明显;穿抓绒衣可有效增加服装系统热阻,但会很大程度地影响充气夹克的保暖调节能力。 相似文献

The article presents the possibilities of using hemp fiber as a loose-fill insulation material. The article presents the results of research concerning raw hemp fiber obtained from the Polish crop of industrial hemp of Bia?obrzeskie variety. The analysis involved evaluation of thermal conductivity in function of bulk density and air permeability, the properties important for insulation materials. The results of laboratory investigation were used to create the numerical simulation models of heat transfer in the frame wall partitions filled with hemp fibers. The study showed that with the increase of bulk density, the thermal conductivity and air permeability of material decrease. The obtained lambda values are comparable with the characteristic values for conventional thermal insulation materials. The results of heat transfer and temperature distribution reveal that hemp fibers characterize with strongly air permeance, what affects on the need for additional barriers against air filtration. 相似文献
