Optimization of Cotton Melange Yarn Quality Using Desirability Function

This paper deals with the optimization of different quality parameters of blow room blended and draw frame blended cotton melange yarn using the desirability function approach. Melange yarn qualities such as tenacity, evenness, imperfection and hairiness index are combined to yield as ‘overall desirability’. The overall desirability has been maximized against target values for yarn tenacity and minimized versus target values for yarn evenness, imperfection and hairiness index. Experimental validation confirms that the applied method can be effectively used to manufacture a cotton melange yarn with desired quality characteristics.
