摘要： 介绍织物的辐射热防护性能 RPP 测试原理。选用 25 种阻燃面料进行测试，分析辐射热源强度与阻燃织物 RPP 值 的关系。借助于 SEM 测试对受热实验后织物微观变化进行表 征，分析实验现象及实验后织物的宏观变化。结果表明：在热流密 度较低的情况下，影响织物辐射热防护性能的主要因素是织物物 理结构参数；本征型阻燃织物的 RPP 值随着热流密度的增加而 减小，非本征型阻燃织物的 RPP 值随着热流密度的增加出现减 小、增加交替现象。热流密度增大时，烧伤时间减小的幅度大于辐 射热流密度增加的幅度，RPP 值总体上呈减小趋势。RPP 值不 宜作为评价织物在宽分布辐射热流量下的辐射热防护性能的唯一 指标。随着辐射热源强度的增加，本征型阻燃织物外观几乎没有 变化，而后整理织物和混纺织物炭化分解逐渐加深。

Abstract: The RPP test principle of radiation heat protection property of fabric was introduced. The relationship between the radiation heat source intensity and the RPP value of the flame retardant fabric was analyzed by 25 kinds of common flame retardant fabrics. The microcosmic changes were characterized by SEM, experimental phenomena and macroscopic changes of the fabric after the experiment were analyzed. The results showed that the physical structure parameters of the fabric are the main factors affecting the radiant heat protection performance of the fabric under the condi⁃ tion of low heat flux density. The RPP value of non-essential flame retardant fabric decreases with the increase of heat flux, while the RPP value of non-essential flame retardant fabric decreases and increases alternately with the increase of heat flux. When the heat flux increases, the burn time decreases more than the radiation heat flux increases, and the RPP decreases. RPP value cannot be used as the only index to evaluate the radiant heat protection performance of fabric. With the increase of radiation heat source inten⁃ sity, the appearance of essential flame retardant fabric hardly changes, and then the carbonization decomposition of finished fabric and blended fabric gradually deepens.
