Taguchi Optimization to Determine Optimal Denier of the Polyester Fibre

Abstract

Polyester fibre is the synthetic fiber made with man-made fibers. Its surface is smooth with the texture of fine linen. It has good flexibility and durability and is the best non-iron fibres. In order to promote the accuracy and reduce the quality deviation of melt spinning, the Taguchi method was adopted in the melt spinning process. The aim of the research is to enhance the optimization of the melt spinning process using the material polyester. First, the Taguchi method is applied to establish the design of experiment. An analysis of variance will be done to arrive at the significant factors that influence the melt spinning quality the most. Lastly, confirmation experiments verified the reproducibility of this experiment. Confirmed by the experiments, results showed that the obtained SN ratios were greater than the signal-to-noise ratio of nine orthogonal array experiments and this means the experiment is reliable.
