Abstract
This paper analyses collected data from an actual dyeing process in the field and proposes a prediction model of the rate of dyeing curves based on variables that affect dyeing fixation on polyester fiber. Analysis of variance is used to find varying relationships between the variables and temperate rising velocity and maintain time. The relationships show different results based on color strength. For medium color fabric, the temperature rising velocity is positively correlated with the length and volume of the fabric. For darker color, the rate is found to be negatively correlated with weight of the fabric. A multiple regression model that predicts maintaining time of dyeing process depending on color, weight and length is proposed. A prediction model for the temperature rising velocity based on the same factors is found statistically significant but the coefficient of determination is considered too low for a prediction model.
