Analysis of spinning process parameters on development of spun-dyed PET yarn using the Taguchi method

Abstract

The yarn tenacity of a spun-dyed yarn is predicted from the spinning conditions and other properties of the yarn are analyzed through the defined parameters using the Taguchi method. To develop a spun-dyed yarn using the Taguchi method, four factors that can largely influence the yarn properties are selected. From the experimental design based on four factors, the processes are executed to produce the specific yarns whose properties are measured to analyze the relationship between the process conditions and their results. The target properties of a spun-dyed yarn may be obtained through adjusting the spinning parameters that are related to the yarn properties by the Taguchi tool. (c) 2006 Wiley Periodicals, Inc.
