Design Optimization of Processing Parameters for Polypropylene Fiber Based on the Taguchi Method

Melt spinning is the method that is most frequently used for manufacturing man-made fibers, while as-spun-fiber is the most important physical nature mainly of breaking strength for processing parameter will base on spinneret temperature, cooling temperature, cooling wind speed, and winding speed and so on to affect its physicality. First of all, suitable orthogonal arrays will be chosen to be applied on experiment plan to conduct experiment, and then it will work with SN (signal-to-noise) ratio and main effect analysis to appreciate the extent of impact of processing parameter on the quality, and confirm its reproducibility. As such, the optimized combination of processing parameters can be obtained.
