单层与多层叠合非织造布透气性的关系

Permeabilities Relation Between Single Layer and Multilayer Laminated Nonwovens

本文运用流体经过均匀多孔介质时的层流运动理论，推导出单层非织造布与多层自然叠合非织造布之间的透气性关系，并用实验加以论证其关系式的正确性。

In the paper, the relation of permeabilities between single layer nonwovens and multilayer nonwovens is worked out by the use of the layer-flow movement theory when the fluid moves through a evenness perforated medium, and the correctness of this relation is demonstrated by the test data.
