ActiveNonwovens—Test method for porosity
非织造布 孔隙率测试方法
Application Summary AI generated
This standard specifies the test method for determining the porosity of nonwoven fabrics, defining procedures for measuring the ratio of void volume to total volume. It is applied in the textile industry for quality control and product development of nonwovens used in filtration, hygiene products, and medical textiles, where pore structure directly affects performance. The method is relevant for manufacturers and testing laboratories evaluating material permeability, liquid absorption, and barrier properties.
