Parameter Optimization by Taguchi Method for Thermoplastic Polymer Using a Melt Spinning Machine\

Fused spinning method is the most commonly used method to manufacture man-made fiber and the most important physical property of as-spun fiber is tenacity, which is affected by process parameters including spinning nozzle temperature, cooling temperature, cooling wind speed and winding speed. First, we selected the appropriate orthogonal array for the experimental plan to conduct experiments. Coupled with signal-to-noise (SN) ratio and main effect analysis, we understood the impact of process parameters on quality and confirmed the reproducibility of the experiment, and furthermore obtained the optimal combination of process parameters.
