  • For the development of high quality textiles, silk fabrics were dyed repeatedly with persimmon juice by padding mangle. We evaluated the mechanical properties and hand value by Kawabata Evaluation system for dyed silk fabrics. The results obtained from this study were as follows. With the increase of repeating padding times of dyeing, the linearity load-extension curves of the silk fabrics were increased; however, the tensile resilience of fabrics decreased. The hysteresis values of shear force were increased without significant change of shear stiffness. The coefficient of friction values were also decreased and geometrical roughness values were increased. The silk fabrics dyed with persimmon juice had shown the thickness and weight grow as the number of padding increases. The hand values of silk fabrics which were classified into 6 items in the Kawabata Evaluation System, were evaluated as repeating times of dyeing with persimmon juice. The hand values of Koshi(stiffness) and Hari(anti-drape stiffness) were increased, whereas Shinayakasa (flexibility with soft feeling) and Fukurami(fullness and softness) were decreased by dyeing with persimmon juice. However there was no significant change in hand values according to repeating padding times of dyeing.

  • Various fabrics, including natural fibers, regenerated cellulosic fibers, synthetic fibers, blend yarn, and mixture fabrics, were treated with the solutions of high purity chitosan in 1% acetic acid, having high viscosity of 930cps or low viscosity of 8cps. Physical/ mechanical properties of the treated fabrics samples were measured using Kawabata Evaluation System and drape tester. From these, hand values and total hand values of the fabric samples were calculated using Kawabata-Niwa translation equations. KOSHI, SHARI, HARI values have increased for the treated samples, while FUKURAMI values have decreased in general.

  • In order to introduce the touch to engineering and industries, it must be preceded to dstablish a quantitative barometer of the feeling. for this purpose, we developed a tactile measuring system to measure physical properties of texture, such as surface roughness, friction coefficient and compliance. The tactile measuring system uses a LASER type displacement sensor, which is a non-contacting system, in measuring the surface roughness. By considering that human tactile system is a contacting mechanism, this non-contacting method needs to be modified. As a precedent research of that, we compared the contacting and non-contacting method in this paper. Surface roughness of ten cloths were measured by using the measuring system, then compared to the test results using the Kawabata evaluation system(KES), which uses a contacting method in measuring the surface roughness.

  • Synthetic fabrics, such as nylon and polyester, were dyed with persimmon juice by using a padding mangle repeatedly. The mechanical properties of these synthetic fabrics were analyzed using the Kawabata evaluation system. The following findings were obtained from this investigation. As the number of repetitions of padding dyeing increased, the tensile energy per unit area and the tensile resilience of synthetic fabric remained almost unchanged, whereas the linearity of the load-extension curve of the synthetic fabrics increased. As the number of padding repetitions increased, the synthetic fabrics dyed with persimmon juice exhibited increases in thickness and weight. As the number of repetitions of padding treatment with persimmon juice increased, the values of stiffness, anti-drape stiffness, fullness, and softness also increased, whereas the flexibility with soft feeling, crispness, and scrooping sensation significantly decreased. The amount of coated persimmon juice on the surface of the fabrics increased after three repetitions of padding treatment with persimmon juice. Nylon and polyester fabrics were dyed evenly with persimmon juice treated using a padding mangle.
