 This study uses the Taguchi method and gray relational analysis to identify the optimal levels of coating process parameters for cotton-villaste and blend denim fabrics, resulting in a combination of tear strength and stiffness properties. The most effective parameters are weft density and fabric passing speed, with an optimal common combination found as 14px cm weft density, 160°C drying temperature, 50 dpa.s viscosity, 3 bar squeeze pressure, and 30m minute fabric passing speed.
