A Fabric Sound Evaluation System for Totally Auditory-Sensible Textiles

Abstract

In order to provide a fabric sound evaluation system for designing auditory-sensible fabrics, sound parameters are obtained, including the level pressure of total sound (LPT), sound color factors (Δ L and Δ f ), three coefficients (ARC, ARF, ARE) of autoregressive models based on the fast fourier transform spectrum, loudness(Z) and sharpness(Z) from Zwicker's psychoacoustic models, and mechanical properties from KES values for wool suiting fabrics. As psychophysical characteristics, subjective sensations of softness, loudness, sharpness, clearness, roughness, highness, and pleasantness of the fabric sounds are evaluated by the free modulus magnitude estimation. Tropical wool has the lowest loudness(Z) and the highest Δ L value among the fabrics. Melton, a thicker and heavier woolen, shows a trend similar to saxony and flannel for sound parameters. Wool suiting fabrics have higher scores for loudness and highness rather than clearness and pleasantness, except for tropical wool, which has the highest scores for pleasantness among the fabrics. Using the modified stepwise regression of Kawabata, all sensations are predicted by both sound parameters and mechanical properties. The sound sensation of wool suiting fabrics is related mainly to tensile, surface, and shear properties in mechanical measurements and with autoregressive coefficients as sound parameters.Fabric sounds have recently attracted both researchers and manufacturers of textiles and apparel. Fabric sound affects the sensorial comfort of clothing [ I ]. Because consumers are interested in the sensorial qualities of fabrics, auditory-sensible textile products are expected to broaden the market now more than at any other time. The tactile and visual aesthetic performance of textiles is already commonly understood, but auditory-sensible textiles are in the early stages of development and production. There have been only a few reports on fabric sound: Fukuhara reported that two edges of a micro-slit in a trilobal-shaped cross section of a polyester fiber imitate silk-scrooping [4]. To develop textile products with auditory comfort for the sensory satisfaction of consumers, however, the physical characteristics of fabrics that can be measured should be identified for application in the manufacturing process. In previous studies [2, 31, we discussed the relationship between the physical characteristics of fabric sounds and the mechanical properties of the fabrics. In addition, we observed some physiological responses to the rubbing sounds of several fabrics, including silk and polyester, in order to determine the relationship between objective physical measurements and human physiological attributes [13]. An approach by Pollard [9] proposed that complex sounds such as music may be determined by following three levels of sound analysis-physical, psycho-physical, and feature analysis. According to this suggestion, fabric sound can be, subjected to psycho-physical and feature analysis as well as physical analysis, indicating the usefulness of h...

Fabric Sound Depends on Fiber and Stitch Types in Weft Knitted Fabrics

“…Given the importance of fabric sound in the textile and clothing industry, many textile research papers have focused on quantifying the sound of various fabrics and understanding the relationship between sound and mechanical properties [1][2][3][4][5][6]. However, most of this research has focused on woven fabrics, not on knitted fabrics.…”

Intelligent Model to Investigate the Sound of Woven Fabric by Using Signal Processing and Artificial Neural Network

“…Fabric sound can affect psychological stability of the garment wearer and others in the vicinity of the garment user (Cho et al, 2009). Fabric sound can be either pleasant or irksome, the extent of which is dependent on circumstances (Yi and Cho, 2000;Yi et al, 2002;Yi, 2005).…”

“…Fabric sound amplitude and frequency are considered to be affected by factors such fabric friction, roughness, shear, and bending stiffness (Yi and Cho, 2000). Previous researches in the field of fabric sound have investigated the fabric sound in relation to mechanical properties of the fabric and have attempted to characterize frictional generated fabric sound (Yi et al, 2002;Cho and Yi, 2000). Fabric sound has been objectively analyzed in terms of the effect of constituent fiber cross-section shape, fiber type, and weaves Kim et al, 2002).…”

Characteristics of sounds generated from vapor permeable water repellent fabrics by low-speed frictions

“…In the previous studies of fabric sound, the relationship between mechanical properties and sound parameters for various fabrics has been investigated to quantify the characteristics of frictional sounds [3][4][5]. The fabric noise has been analyzed by cross-sectional shapes of fibers, fiber type, and weaves to calculate objective factors affecting them [6][7][8].…”
