Using genetic programming to predict the macroporosity of woven cotton fabrics

This paper reports the effect of woven fabric construction on macroporosity properties. The area of a macropore's cross section, equivalent, maximum, and minimum pore diameters, pore density, and open porosity are observed in this research involving woven fabric construction parameters-yarn linear density, fabric tightness, weave type, and denting. Predictive models, determined by genetic programming, are derived to describe the influence of fabric construction. The results show very good agreement between the experimental and predicted values. This work provides guidelines for engineering stapleyarn cotton fabrics in a grey state in terms of macroporosity properties.
