  • The hand of the sensitive mixture fabrics was analysed and discussed with measured mechanical properties of two kinds of woven fabrics according to the characteristics of air-jet loom. The 16 mechanical properties such as tensile, bending, shear, compression and surface were measured using KES-FB system and their differences of the mechanical properties between domestic and foreign looms were analysed with the deviation according to the position of the specimen. And also these mechanical properties according to the domestic and Japan air-jet looms were analysed and discussed with warp and weft insertion tensions during weaving. This research is aiming to make a data base of fabric mechanical properties and, these analysed data are given to weaver as a basic research data related to the effects of loom characteristics to the sensitive mixture fabrics required from weaving fields.

  • Polypropylene nonwoven fabrics were exposed to He/$O_2$ atmospheric pressure glow discharge plasma. Surface chemical analysis and contact angle measurement revealed the surface oxidation by formation of new functional groups after plasma treatment. Weight loss (%) measurement and scanning electron microscopy analysis showed a significant plasma etching effect. It was investigated in low-stress mechanical properties of the fabrics using Kawabata Evaluation System (KES-FB). The surface morphology change by plasma treatment increased surface friction due to an enhancement of fiber-to-fiber friction, resulting in change of other low-stress mechanical properties of fabric.

  • In this study, the correlations of the two frictional testers have been investigated; one is the KES-FB4 system, the other is the Fabric-on-Fabric Frictional tester which was devised by authors. According to the results, the correlation between the frictional coefficients measured by the two testers has been shown highly as the load increased. But the effect of roughness of fabric surface was not dearly revealed in this study. The frictional characteristics of fabric woven from filament yarns were different with those of fabric woven from spun yarns. And, like the other materials, the effect of load on fabrics used in this experiment was related with the frictional force between two fabrics. The frictional behaviors, however, were obviously different with harder material because the frictional coefficients were not constant as the load increased.

  • In order to investigate the mechanical properties of working clothes materials considering industrial settings, the test weaving materials were compared with the existing materials depending on the season. The material design of the test fabrics were changed through fineness, composition, density of materials then subsequently treated with functional finish. As a result of evaluation of the forms according to KES-FB system, Koshi was deduced, and Numeri and Fukurami were increased. Thereby, the test weaving materials became flexible, surface became smoother, elasticity and volume characteristics indicated to have been improved. Consequently, the THV value of working clothes materials for test weaving was increased compared to existing materials which indicated improved result of the total hand value. Specially, the winter cloth material indicated improved drape characteristics and dimensional characteristics, showed improved liveliness as being compressed softly.

  • 본 연구에서는 표면처리를 달리한 폴리에스테르/면 교직물에 대한 표면특성의 측정기법을 비교·검토하였다. 시료로는 미처리 직물과 silicone 처리 직물, pu 코팅직물, silicone/pu 처리 직물을 이용하였다. 측정 기법은 비접촉식 방법으로 위치에 따른 직물 표면잔털의 grey scale을 FFT하여 그 대수값의 관계식의 기울기값을 결정하였다. 또한, 레이저 변위센서를 이용한 촉각 측정 장치에 의해 표면 거칠기와 표면마찰 계수를 측정하였다. 접촉식 방법으로는 평판과 직물을 접촉시켜 영상처리에 의해 접촉면적을 정량하고 fractal 차원을 도출하였다. KES-FB system에 의해 표면특성을 측정하였다. 주관적 접촉감각 평가는 표준환경에서 20명의 여성을 대상으로 실시하였고 분석에 ANOVA와 상관분석을 이용하였다. 측정기법에 따른 표면특성치와 주관적 감각평가치의 상관분석 결과, 접촉식 방법인 KES-FB에 의한 방법보다 다른 접촉식 방법인 영상처리에 의한 접촉면적, fractal 차원과 비접촉식 방법인 FFT 분석에 의한 기울기 및 레이저 변위센서에 의한 표면거칠기 결과가 주관적 접촉감각과 더욱 밀접한 관련이 있는 것으로 나타나 접촉 감각을 객관화하는데 보다 타당한 것으로 나타났다.

  • The purpose of this study is to verify the visual perception on various cotton fabrics of the same color. Results obtained through subjective evaluation of cotton fabrics showed that the textural adjectives could be classified into 3; warm/cool, flexibility and surface property, the sensibility adjectives into 5; simple, attractive, masculine, conservative, comfortable and visual perception adjectives into 6; hard, warm, smooth, brilliant, classic and casual. Image distribution results on 12 different fabrics, showed different distributions among textiles on visual perception due to varying texture and sensibility. In thickness, weight, weave type, bending and surface characteristics which are structure characteristics, significant differences were shown for visual perception examination. Having placed into an image scale, visual perception dimension developed divided into the 'soft-hard' axis and the 'warm-cool' axis.

  • The purpose of this study is to examine the hand of spring/fall fabrics for 'Saenghwal Hanbok' on subjective hand, objective hand and the preference. In this study, 28 varieties of spring/fall fabrics such as cotton fabrics, synthetic fabrics, blended fabrics and a silk fabric for 'Saenghwal Hanbok' are used. To evaluate the subjective hand of fabrics, the holistic touch and preferences, 33 seven ranks' segmentic differential scale questions are developed with adjective pairs and are gathered by surveying experts on clothes. The mechanical properties, HV and THV of them are measured and calculated by KES-FB system. Through subjective hand, items could be classified into six hand expressions: 'bulky/extensibility', 'stiffness', 'feeling of weight', 'surface property', 'drapability' and 'moisture property'. Through mechanical properties, the results indicated that the character of cotton fabrics are slight flexible, tough, rough, uneven, a bit heavy, thick and low resilience on tensile and compression, and then those of synthetic fabrics, blended fabrics and a silk fabric are thin and light, smooth, flat and bulkless. In correlation on subjective evaluations and the preference for 'Saenghwal Hanbok', cotton fabrics mainly depend on 'surface property' and 'moisture property' and then synthetic fabrics, blended fabrics and a silk depend on 'bulky/extensibility' and 'surface property' In correlation on objective hand and the preference for 'Saenghwal Hanbok'. people aren't satisfied with low resilience. high stiffness and low drape.

  • In this study, breathable waterproof materials were prepared by electrospinning. Five kinds of electrospun nanofiber web layered systems with different levels of nanofiber web density, as well as different substrates and layer structures were fabricated, and their mechanical properties (tensile, bending, shear, compression, surface, and thickness & weight) were measured by the KES-FB system and compared with those of conventional breathable waterproof fabrics (densely woven fabric, PTFE laminated fabric and PU coated fabric). The KES-FB measurements demonstrate that the lab-scale nanofiber web layered systems are more flexible and fuller than commercial nanofiber web layered systems, which have a more compact structure than the lab-scale nanofiber web layered systems. Densely woven fabrics and lab-scale nanofiber web layered systems showed lower values of tensile linearity (LT), bending stiffness (B), and shear stiffness (G) than those of PU coated and PTFE laminated fabric. These results indicate that they are more flexible and have less resistance to the shearing movement, corresponding to a more pliable material having a better drape, than PU coated fabrics and PTFE laminated fabrics.
