The permeability of fiber-based materials and general medical textiles is very important, it commonly believed that air water are correlated. This property expressed as the breathability material. Knowing helpful in predicting vapour well, but whether this really works for at different pressures humidities still needs to be explored. In study, hypothesis examined, discovered phenomenon does not...

This paper describes an experimental study aimed at evaluating the influence of soil microstructure on air permeability in compacted clay. Air measurements, estimated using gas pressure decay method, were carried out for a wide range compaction states. The evolution during wetting and drying paths was also evaluated. results show that, increase as-compacted degree saturation, may either or decr...

This research study experimentally analyzed the effect of ring and rotor yarns which are 100% cotton spun yarn with 30s Ne count on physical comfort characteristics single jersey, rib, interlock knitted fabrics. The such as fabric Thickness, Tightness factor, Bursting strength, Abrasion resistance, Pilling behavior were studied according to ASTM Standard statistically using Minitab software ANO...

A fabric?s moisture/air permeability is a main factor for the fabric design advanced applications, and no theoretical model was available in literature an optimal permeability. In this paper, we use capillary-like effect to elucidate property, of nano/micro particles on surface studied by geometric potential theory. Our analysis shows that unclean gives negative impact superhydrophobic needed g...
