< jats: title>摘要< jats: p>采用一种分析方法预测了用作过滤织物的非织造厚合成膜的过滤性能。许多商业织物的形态分析已被用来确定负责其水力性能的内部结构参数，并预测这些织物中的颗粒的透水性和保留。< jats: p>进行实验性过滤测试以收集用于预测堵塞水平的水渗透率的数据。用图像分析仪测量了织物的纤维密度和孔径直方图，并建立了织物的透水性与纤维密度之间的关系。< jats: p>最后发现，厚度大于1.5 mm的无纺布的孔径直方图可以简单地通过测量其透水性并使用经验相关性来计算。
< jats: title> Abstract< jats: p> The filtration performance of non‐woven thick synthetic membranes used as filter fabrics is predicted from a proposed analytical method. The morphological analysis of many commercial fabrics has been utilized to identify internal structure parameters responsible for their hydraulic properties and also to predict the water permeability and the retention of particles in these fabrics.< jats: p> Experimental filtration tests were performed to gather data on the water permeability used in predicting clogging level. Also fibres' density and pore size histograms of fabrics were measured with an Image Analyser and a relationship was developed between the water permeability and the fibres' density.< jats: p> Finally it was found that the pore size histogram of non‐woven fabrics of thickness greater than 1.5 mm could be calculated simply by measuring its water permeability and using an empirical correlation.
