| 摘 要： | 采用临界区思想推出了粉末粘结非织造布拉伸强度的理论估计模型。并根据模型需要对纤维从粘结纤维网中的平均抽拔力进行实测,进而对模型参数进行估计,最终实现对强度的估算。通过对比,发现强度的理论估计值和实测值与粉末含量的关系具有相同的趋势。由于理论的假设,使理论值与实测值之间存在差异,但它们之间存在着良好的线性关系。

| Abstract: | A theoretical modelling of tensile strength of powder bonded nonwovens is deduced according to the concept of critical zone. The pull - out force of single fibre from powder bonded nonwoven samples prepared in laboratory are tested based on the need of this model, then the model parameters estimated, and the tensile strength is calculated. The test results are compared with the predicted values based upon the proposed model. It is shown that the relationship between the theoretical values and the structure parameters varied in the same way as that of the tested results obtained. |
