PTFE覆膜防水织物的透气性研究

Study on Wet Permeability Properties with PTEE Membrane

以真丝、棉机织物和无纺布为研究对象,研究3类织物与聚四氟乙烯微孔薄膜复合后,覆膜织物的服用性能。PTFE覆膜织物有好的防水性,在透气性方面,基布透气性与孔隙率成正相关,与厚度无关;但覆膜后织物的透气性由PTFE覆膜本身透气性决定。

In this paper, three kinds of silk, cotton and nonwoven fabrics were covered with PTEE membrane, their permeability were researched. The fabrics covered with PTEE membrane owned good water resistance. The gas permeability of the fabrics is related with the porosity but not the thickness. But the gas permeability of the fabric covered PTEE is determined by the gas permeability of PTEE membrane itself.
