Applying the taguchi method to enhance soil and stain removal

摘要

Mandated energy savings and changes in detergent formulation and consumer laundry practices push the washing machine industry to understand more completely how various factors affect soil and stain removal. We examined the laundry process from a holistic perspective by integrating important factors. The Taguchi experimental design method weighs all factors equally in assessing the impact of accelerated laundry variables on soil/stain removal. Dependent variable was stain/soil removal; independent variable were stain/soil type, fabric, wash time and temperature, detergent, and agitation. We used AATCC 151 Soil redeposition: Launder-Ometer Method and evalauted results by calculating the change in specimens' Y-values.
