摘要
为研究消防服用织物的湿态热防护性能,以4种适宜用作消防服装多层结构的面料为试样,通过热辐射和热对流综合热防护性能实验(TPP实验),测试织物在5种湿状态下热辐射和热对流综合热防护值TPP和二级烧伤时间,比较不同层面料吸湿后热防护性能的变化。用SPSS软件分析了单层织物吸湿后含水率对二级烧伤时间和TPP值的影响。结果显示,在高强度热流量短时间作用情况下,水分有助于提高单层织物的热防护性能。二级烧伤时间和TPP值均随面料含水率的增大而增大,含水率与二级烧伤时间和TPP值之间存在显著的线性正相关关系,并在TPP值、二级烧伤时间与含水率之间建立了一元线性回归方程。
To study the wet thermal protective performance of fabric for fire fighters wears, 4 kinds of fire- retardant muhilayer fabric suitable for fire fighters wears were used as samples, and the thermal protective performance value （TPP value ） of the sample fabrics were tested through thermal radiation and thermal convection integrated experiment under 5 kinds of wet state and required time leading to the second-degree burn. Different layer fabrics＇ thermal protective performance after absorbing water was compared. Then the effect of single layer fabric＇s moisture content percent after absorbing water on the second-degree burn time and TPP value was studied by SPSS software. The findings revealed that in the case of short time and high intensity heat flux, water is benefit to improve single layer fabric＇s thermal protective performance. Both the TPP value and the second-degree burn time increase with the moisture content. There are positive correlation relationship between moisture content percent, the second-degree burn time and TPP value. Simple linear regression equations are developed between TPP value, the second-degree burn time and moisture content percent.
