研究了具有不同重叠配置和0.5 mm至5 mm之间的各种厚度的非织造布的火灾危险性，以澄清重叠配置的差异引起的可能的恶化情况。热薄非织造布的火灾危险性的特征在于火焰蔓延，火焰高度，温度分布和质量损失。随着非织造布厚度的增加，火焰蔓延速率和火灾发展指数先增大后减小。OL构型（逐层重叠构型）样品的火灾危险性高于AO构型（手风琴式重叠构型）样品，表现在FDI、平均火蔓延速率和火焰高度较高，着火时间较短。通过对传热机理的分析，确定了两种重叠结构火灾危险性的差异。由于包装方法的不同，AO和OL构型的非织造布在燃烧过程中表现出不同程度的收缩和卷曲效应。层间较大的气隙和样品边缘的重量是AO结构样品收缩较弱的原因。OL型试样的收缩增强了预热区的对流换热，在一定程度上强化了火焰传播。
The fire hazard potential of nonwovens with different overlap configurations and various thicknesses between 0.5 and 5 mm were investigated to clarify the possible worsening situation induced by the difference in overlapping configurations. The fire hazard of thermally thin nonwovens is characterized by flame spread, flame height, temperature distribution, and mass loss. The flame spread rate and FDI (fire development index) increase and then decrease as the thickness of the nonwovens increases. The fire hazard potential of samples with OL configuration (overlapping layer by layer configuration) is higher than that with AO configuration (accordion-style overlap configuration), which is reflected in the high FDI, average fire spread rate, and flame height, and low ignition time. The difference between the fire risk of the two overlapping configurations was confirmed by analyzing the heat transfer mechanism. Due to the different packaging methods, the AO and OL configurations of nonwovens show different degrees of shrinkage and curling effects during combustion. The large air gap between the layers and the weight of the sample edge are the reasons for the weak contraction of the sample with an AO configuration. The sample shrinkage with OL configuration strengthens the flame spread to a certain extent by increasing the convective heat transfer in the preheat zone.
