纺织品上火焰传播的定性观察表明，纤维素织物、尼龙织物和绒毛纤维素材料的控制机理不同。对于纤维素织物，重要的过程包括从火焰到原始材料的热传递和可燃蒸汽的产生来为火焰提供燃料。纤维素织物的精细结构（即孔隙率和交织几何形状）似乎不影响火焰传播速度。相反，火焰传播速度主要与单位面积的织物质量有关，正如de Ris的固体燃料火焰传播理论或燃烧材料的固-气界面处的简单能量平衡所预测的那样。对于尼龙织物，火焰传播过程的物理性质受到其热塑性行为的极大影响，即受到收缩、熔化和滴落的影响;对于绒毛纤维素材料，受到火焰跳跃、阴燃和重力引起的火焰熄灭的影响。进一步的实验和理论研究...
Abstract Qualitative observations of flame spreading over textiles indicate different governing mechanisms for cellulosic fabrics, for nylon fabrics, and for fuzzy cellulosic materials. For cellulosic fabrics, the important processes involve heat transfer from flame to virgin material and generation of combustible vapors to fuel the flame. The fine structure (i.e. the porosity and the interlacing geometry) of the cellulosic fabrics does not seem to affect the flame-spreading speed. Rather, the flame-spreading speeds are related primarily to fabric mass per unit area, as predicted by de Ris's solid-fuel flame-spread theory or by a simple energy balance at the solid-gas interface of the burning material. For nylon fabrics, the physics of the flame-spreading process are greatly affected by their thermoplastic behavior, i.e. by shrinking, melting and dripping; and for fuzzy cellulosic materials, by the occurrence of fire jumps, smoldering and gravity-induced flame blow-outs. Further experimental and theoretic...
