Abstract

The influences of ultrasonic dyeing on color values, color fastness and tensile properties of

PBT yarns were assessed by comparing the conventional dyeing method. The darker colors

were generally achieved by conventional dyeing with more saturated colors. Because of the

lower color strengths of ultrasonic dyed PBT yarns, unacceptable color and hue differences

were obtained according to commercial tolerances. The color fastness results to washing of

conventional and ultrasonic dyed PBT yarns were almost same. Ultrasonic energy reduced the

elongation of PBT yarns while the tensile strengths of both ultrasonic and conventional dyed

samples were similar.

Keywords: Ultrasonic dyeing, PBT fiber, Color strength, Tensile strength, Washing fastness.
