Fractal Derivative Model for Air Permeability in Hierarchic Porous Media
Abstract and Applied Analysis, 2012 Air permeability in hierarchic porous media does not obey Fick's equation or its modification because fractal objects have well-defined geometric properties, which are discrete and discontinuous. We propose a theoretical model dealing with, for the first

Effect of Yarn Linear Density and Thread Density on the Air Permeability of Light- to Medium-Weight Plain Woven Fabric Derivatives Used as Summer Shirting Fabrics [PDF]
Tekstilec, 2018 This article presents the results of an analysis of the air permeability behaviour of shirting fabrics. Woven fabrics comprising derivatives of plain fabric, such as voile, poplin and canvas, were selected.
