Abstract

Thermal protective performance of protective clothing is greatly affected by structural parameters of fabric, air gap, and orientation of testing. This paper used Box-Behnken design experimental design to see the influence of pick density of shell (outer) layer, air gap, and orientation of test on thermal protective performance in terms of protection time. The testing was done at constant radiant heat flux. Thermal protective performance was measured in terms of second degree burn time using Stoll’s curve. The model showed F value of 72.98 and p-value 0.0001 which shows that model was significant. It was also found that there was significant effect of pick density, air gap, and orientation angle on thermal protective performance. There was positive effect of pick density and air gap but negative effect of orientation angle. This was also observed that effect of pick density was more when air gap increases. The study can help in development of thermal protective clothing for different parts of body.

测试方向对多层防寒服外层辐射防护性能的影响

防护服的热防护性能受织物结构参数、气隙和测试方向的影响很大。本文采用 Box-Behnken 设计实验设计来观察外壳（外层）的撷取密度、空气间隙和测试方向对热防护性能（防护时间）的影响。测试是在恒定辐射热流量下进行的。热防护性能是通过斯托尔曲线以二度灼伤时间来衡量的。模型显示 F 值为 72.98，P 值为 0.0001，表明模型是显著的。研究还发现，取样密度、气隙和取向角对热保护性能有显著影响。取样密度和空气间隙有正效应，但取向角有负效应。同时还发现，当空气间隙增大时，取样密度的影响更大。这项研究有助于开发适用于人体不同部位的热防护服。

期刊介绍： Fire Technology publishes original contributions, both theoretical and empirical, that contribute to the solution of problems in fire safety science and engineering. It is the leading journal in the field, publishing applied research dealing with the full range of actual and potential fire hazards facing humans and the environment. It covers the entire domain of fire safety science and engineering problems relevant in industrial, operational, cultural, and environmental applications, including modeling, testing, detection, suppression, human behavior, wildfires, structures, and risk analysis. The aim of Fire Technology is to push forward the frontiers of knowledge and technology by encouraging interdisciplinary communication of significant technical developments in fire protection and subjects of scientific interest to the fire protection community at large. It is published in conjunction with the National Fire Protection Association (NFPA) and the Society of Fire Protection Engineers (SFPE). The mission of NFPA is to help save lives and reduce loss with information, knowledge, and passion. The mission of SFPE is advancing the science and practice of fire protection engineering internationally.
