| Abstract |
| The objectives of this study were to investigate the psychoacoustic properties of PTFE(Poly tetra Fluoroethylene) laminated vapor permeable water repellent fabrics which are frequently used for sportswear, to examine the relationship among fabrics`` basic characteristics, mechanical properties and the psychoacoustic properties, and finally to propose the predicting model to minimize the psychoacoustic fabric sound. A total of 8 specimens`` frictional sound were recorded and Zwicker`s psychoacoustic parameters such as loudness(Z), sharpness(Z), roughness(Z), and fluctuation strength(Z) were calculated using the Sound Quality Program. Mechanical properties of specimens were measured by KES-FB system. Loudness (Z) of specimen D-1 was the highest, which means the rustling sound of the specimen D-1 was the most noisy, Statistically significant difference among film type was observed only in loudness (Z) for fabric sound, Based on ANOVA and post-hoc test, specimens were classified into less loud PTFE film group (groupⅠ) and loud PTFE film group (groupⅡ). Loudness (Z) was higher when staple yarn was used compared when filament yarn was used. According to the correlation between the mechanical properties of fabrics and loudness(Z) in groupⅠ, the shear properties, compression properties and weight showed positive correlation with loudness(Z). According to the regression equation predicting loudness(Z) of groupⅠ, the layer variable was chosen. In groupⅡ, variables explaining the loudness(Z) were yarn types and shear hysteresis(2HG5). |
