a clear trendgold
From the Surface plot ( Figs 7(A) , 7(B) and Figs 8(A) , 8(B) ) and the scatter diagram ( Fig 9E ), a clear trend was observed in the variation of Finished Fabric Width (FW) and Areal Density (GSM) with Machine Diameter (D), where a raise in machine diameter results in a corresponding increment of Finished Fabric Width (FW).
