The influence of Double Layer Knit Fabric Structures on Air and Water Vapor Permeability

P. Kanakaraj, B.S. Dasaradan, R. Ramachandran


The double layer fabrics are produced in circular knitting machine. The face and back surfaces of the fabrics are connected by a) Loop and b) Tuck. The developed fabrics are taken to measure the water vapor permeability and air permeability properties. The test results were discussed statistically with ANOVA single factor data analysis. The significant results in the analysis of variance concluded with Tukey’s least significant test. Based on the tests conducted in this study, between double layer structures are highly significant on the WVP and air permeability property of the knit fabrics. The stitch density in the fabric surfaces influence more on the permeability property of the fabrics.
