The purposes of this research is to determine the optimal process parameters of woven fabric production process and the rank of factors that infuence the responses of  the fabric, namely tensile strength, tear strength, air permeability, drape ability and pilling. In this research, Taguchi method was used in the optimization of woven fabric production by involving four factors, namely weft yarn type, weft density, air pressure and warp tension each with three levels. Orthogonal Array L9 for experiment. Grey relational analysis and principal component analysis was used to determine the optimal process parameters. The results of experiments showed that the sixth treatment of the orthogonal array has the highest rank with a value of 0.803. The optimal settings are TC 30 of weft yarn type, 68 of weft density, 3 bar of air pressure and 1.75 kN of warp tension. Analysis of variance with minitab that weft yarn type become the most influence and significant factors of the responses.
