Classification of Apparel Fabrics according to Rustling Sounds and Their Transformed Colors

The purpose of this study was to classify apparel fabrics according to rustling sounds and to analyze their transformed colors and mechanical properties. The rustling sounds of apparel fabrics were recorded and then transformed into colors using Mori's color-transforming program. The specimens were clustered into five groups according to sound properties, and each group was named as 'Silky', 'Crispy', 'Paper-like', 'Worsted', and 'Flaxy', respectively. The Silky consisted of smooth and soft silk fabrics had the lowest value of LPT, $\Delta$f ARC, loudness(z) and sharpness(z). Their transformed colors showed lots of red portion and color counts. The Crispy with crepe fabrics showed relatively low loudness(z) and sharpness(z), but diverse colors and color counts were appeared. The Paper-like showed the highest value of LPT, $\Delta$f and loudness(z). The Worsted composed of wool and wool-like fabrics showed high values of LPT, $\Delta$f loudness(z) and sharpness(z). The transformed colors of the Paper-like and Worsted showed the blue mostly but color counts were less than the others. The Flaxy with rugged flax fabric had the highest fluctuation strength, and their transformed colors showed diversity.
