摘要： 在实际高温、强热对流等存在显著热风险的作业场景中，阻燃防护服装是确保人员生命安全的关键装备。服装在燃烧过程中的热收缩性能变化，会显著影响阻燃防护服装的热防护效能。本文通过假人燃烧试验，结合三维扫描装置，获取假人燃烧后的烧伤面积占比、烧伤位置分布和三维点云数据。通过Geomagic Studio和Qualify软件，计算服装表面积收缩率、体积收缩率等多个反映服装热收缩性能的特征参数。通过主成分分析法，确定了能够有效反映芳纶1414热防护服热防护性能的热收缩参数，并计算了参与假人燃烧试验服装样本的主成分得分。结果显示，面密度为260 g/m2的服装综合得分值明显小于面密度为230 g/m2的防护服，表现出更优异的耐热收缩性能，进一步说明了服装热收缩与热防护性能具有强相关性，也表明了本文确定的热收缩率特征值能够有效反映芳纶1414热防护服装的热防护性能。

Abstract: In practical working scenarios with significant thermal risks such as high temperature and strong thermal convection, flame-retardant protective clothing serves as critical equipment for ensuring personnel safety. The thermal shrinkage behavior of clothing during combustion significantly affects the thermal protective performance of flame-retardant protective garments. This study conducted manikin burn tests combined with 3D scanning technology to obtain the burn injury area percentage, burn location distribution, and 3D point cloud data after combustion. Using Geomagic Studio and Qualify software, multiple characteristic parameters reflecting the thermal shrinkage properties of clothing were calculated, including surface area shrinkage rate and volume shrinkage rate. Through principal component analysis, thermal shrinkage parameters that effectively reflect the thermal protective performance of aramid 1414 protective clothing were identified, and principal component scores were calculated for clothing samples tested in manikin burn experiments. The results showed that clothing with a fabric density of 260 g/m² had significantly lower comprehensive scores than protective clothing with 230 g/m² fabric density, demonstrating superior thermal shrinkage resistance. This further confirms the strong correlation between clothing thermal shrinkage and thermal protective performance, and validates that the thermal shrinkage characteristic values determined in this study can effectively reflect the thermal protective performance of aramid 1414 protective clothing.
