Design Optimization of Nonwoven Processing Parameters Using Hybrid Taguchi and TOPSIS Approach

Abstract:

This study aimed to apply Taguchi method and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to optimize multiple qualities of needlepunched nonwoven fabrics with the fewest experiments. The quality characteristics are tear strength of machine direction (MD)/ cross machine direction (TD) and tensile strength of MD/TD. From nine experiments based on the L9 orthogonal array, the swing rate of the cross-lapper machine is 1500 rpm, the delivery rate of the cross-lapper machine is 15 cm/min, the depth of the needle penetration is 14 mm, and the punch density is 60 punches/cm2 were found to be the optimal processing parameters. Finally, ten confirmation experiments were executed to ensure the reliability and reproducibility of the TOPSIS predicted optimal conditions with a 95% confidence interval for the needlepunched nonwoven fabrics.
