摘要
为了解和评价消防服舒适层面料的热湿舒适性,并为其设计研发提供参考,对现役消防服常用的 6种舒适层面料进行热湿舒适性测试,并运用灰色综合评价和灰色关联分析对6种消防服舒适层面料的综合热湿舒适性进行评价,分析每种因素对舒适性的影响程度.结果显示隆起管状结构,成分为进口原液芳纶+高性能阻燃纤维,经密375根/10 cm,纬密490根/10 cm,面密度 140 g/m2,厚度为 1.79 mm的面料热湿舒适性综合性能最好,近优度为0.958,最接近1.面料的8种测试指标中透气性对热湿舒适性的影响最大,8种测试指标对近优度的关联度数值在0.8左右,相差不大.消防服舒适层面料的热湿舒适性主要与织物组织结构、紧密度、厚度及面密度有关.
Abstract
In order to understand and evaluate the thermal wet comfort performance of the lining of firefighter protective cloth-ing,and to provide reference for their design and development,the thermal wet comfort performance of six types of lining com-monly used for firefighter protective clothing in service was tested,and the comprehensive thermal wet comfort performance of the six types of lining for firefighter protective clothing was evaluated by using grey comprehensive evaluation,the degree of influence of each factor on the comfort was analyzed by using grey relational analysis.The results showed that the fabric with a bulg-ing tubular structure,imported stoste Nomex fibers and high-performance flame retardant fibres,warp density of 375 roots/10 cm,weft density of 490 roots/10 cm,areal density of 140 g/m2,and thickness of 1.79 mm has the best comprehensive perfor-mance in terms of thermal wet comfort performance,with a pre-mium degree of 0.958,which is the closest to 1.The air perme-ability has the greatest impact on the thermal wet comfort perfor-mance among the 8 test indexes for the fabrics.The relevance of the 8 test indexes to the premium degree is around 0.8,which is not much different.The thermal wet comfort performance of the lining of firefighter protective clothing is mainly related to the fab-ric structure,tightness,thickness and areal density.
