Abstract
The effect of shape parameters of seam puckering on its fractal dimension has been analyzed to evaluate the seam pucker of the garments. The shape of seam puckering has been defined as three-dimensional waves that are generated on the seam line and propagate to the edge line. Five shape parameters are defined to characterize the wavy nature of seam pucker. An objective five-rating method of seam pucker, using fractal geometry, has been suggested with the five AATCC reference puckered samples. The 'Box Counting Method' has been employed to determine the fractal dimension of seam puckers generated by the simulator, as well as measuring them with a laser scanning system. The fractal dimensions of various seam puckers with different shape parameters have been statistically analyzed through experimental design. The five shape parameters of seam pucker distinctly affect its fractal dimension. Also, the fractal dimension of each reference puckered seam has been closely related to its AATCC seam pucker grade. Regression analysis of the fractal dimension with the objective five-rating of seam pucker has been conducted. It has been shown that fractal geometry can be effectively used to objectively evaluate seam pucker. A new objective five-rating as well as a ten-rating scale for a puckered seam using fractal geometry has been suggested as a substitute for the conventional subjective AATCC five-rating method.
