Multi response optimization of yarn strength, imperfections and yarn evenness for rotor spun yarn.

Abstract

In this study, a multiple response optimization model based on response surface methodology was developed to determine the best rotor speed and yarn twist level for optimum rotor yam strength and unevenness and imperfections. Cotton yam of 30 tex, was produced on rotor spinning machine with different twist levels (i.e. 500, 550, 600 and 700 tpm) at different rotor speeds (i.e. 70000, 75,000, 80000, 90000 and 100000 rpm). Yam quality characteristics were determined for all the experiments. Based on the results, a multiple response optimization model was developed using response surface regression on MINITAB® 17 statistical tool.
