Composite waterproof breathable textile fabric made with membrane must be characterized by better water resistance and simultaneously good possible permeability of water vapour in order to use as protective clothing or sportswear. This paper describes an experimental analysis on multi-layered textile-polymeric fabrics prepared by microporous polyurethane membrane along with polyester woven and knitted fabrics. Polyurethane membrane was used with three different polyester plain woven fabrics and a one type of single jersey polyester knitted fabric to prepare two-layered and three-layered laminated fabrics. Different properties of these layered fabrics were analyzed on the basis of their different fabric parameters. Water resistance property was measured by SDL ATLAS Hydrostatic Head Tester, whereas water vapour permeability was evaluated by Permetest. Mechanical properties, i.e., bending rigidity and tensile strength which also play vital roles for the comfortability of the users were measured by TH-7 machine and Testometric M350-5CT machine respectively. From the test results and statistical analysis, it has been obvious that there are significant influences of different fabric parameters, i.e., fabric thickness, fabric weight, fabric density along with other fabric composition on their different properties, i.e., water resistance, water vapour permeability, bending rigidity and tensile strength for these two-layered and three-layered fabrics.
