ABSTRACT

The seven kinds of polyester fabrics having different fabric characteristics were investigated in terms of their dyeing levelness under various liquor ratios. The levelness was evaluated statistically from color strength obtained at different sections of each piece of dyed fabrics. The color strength data were analyzed using a exponential decay function of 3 parameters, y=y0+ae-bx. The b value of the function was used as a index of sensitiveness of dependence on liquor ratio of levelness. The index, b value, showed a linear proportional relationship to thickness of fabrics. Average unlevelness of dyeings exhibited a inverse proportional relationship to both weight and thickness of fabrics.
