热防护服织物性能与综合防护能力的关系

Relationships between thermal protective performance and properties of fabrics

以13种可用于热防护服外层的阻燃织物为试样,通过热辐射和热对流综合热防护性能实验测试织物的TPP值,并计算燃烧前后的质量损失。用SPSS软件研究分析单层织物燃烧前后质量损失、厚度、面密度对其综合热防护性能的影响。研究认为,织物燃烧前后质量损失对其热防护性影响不大,织物厚度、面密度与TPP值之间均有线性正相关关系,但面密度对热防护性的影响没有厚度对热防护性的影响显著。并在TPP值与厚度之间建立了一元线性回归方程。

amples are taken from 13 kinds of fire-retardant fabrics that are suitable for thermal protective clothing′s outer layer,TPPvalues of the samples were tested through thermal radiation and thermal convective integrated experiments,and mass loss before and after combustion was calculated,then SPSS software was used to analyze the effect of mass loss before and after combustion,thickness and weight of single layer fabric on its TPPvalues.It is concluded that theTPPvalue is almost no influenced by mass loss before and after combustion,but more influenced by fabric thickness and weight.The impact of weight on thermal protective performance is not as significant as thickness.And a simple linear regression equation is developed between TPPvalue and thickness.
