A new approach for optimizing water resistance and air permeability of denim cotton fabric

The quality of the denim fabric is a phenomenon that requires successfully meeting several properties at the same time among these properties are air permeability and water resistance Very little study has been carried out on multiple properties and parameters at the same time In this study we used Response Surface Methodology to optimize levels of thickness and optimum and levels of fabric mass per unit area which simultaneously maximize water resistance and minimize air permeability of denim cotton fabric A response surface methodology was employed for data analysis experimental results of denim cotton fabric A set of expressions expressed by contours plot was obtained for predicting the water resistance and air permeability performances of denim fabric quality as a function of fabric thickness and fabric mass per unit area Those fabric rsquo figures were optimized by first graphical approach based on overlaid contour plot and second by the desirability function approach to achieve maximum water resistance and minimum air permeability simultaneously
