Among the components of disposable diaper, the top sheet contacting with baby skin directly is usually made of nonwoven fabrics. Therefore, the tactile properties of the nonwoven fabrics are important for the skin health of infants. In this study, we have explored the surface properties of hygiene nonwoven fabrics (100% cotton spunlace, 100% tencel spunlace, 100% polypropylene (PP) thermalbonding and 100% PP Thru-air bonded carded web (TABCW)), such as friction coefficient and geometrical roughness. used by KES-F system and a laser displacement sensor. Also, we evaluated the subjective responses about the hygiene nonwoven fabrics used by a questionnaire and compared with the objective values, measured by KES-F system and a laser displacement sensor respectively. From the result, we have found that surface sensation (such as soft, smooth, and rough) and bulkiness sensation (such as spongy and fluffy) of nonwovens were represented excellently by L-SMD values which are measured by a laser displacement sensor.

In this study, the effect of sizing on the physical and mechanical characteristics of Hansan ramie was studied. 2 kinds of Hansan ramie were used for this study and one kind of the chinese ramie was also used for comparing with the characteristics of Hansan ramies. The following results were obtained from this experimental study. The wrinkle recovery angle was gradually reduced according to the increasing of the concentration of sizing agent. As the size agent could easily penetrate between the thick yarms, the effect of sizing on the wrinkle recovery angle was evident on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently on the Chinese and Hansan coarse ramie. The result of KES-F system showed that the sizing affected much on the bending properties and shear properties. As the size concentration was increased the shear properties were increased more evidently than the bending properties. The other mechanical properties didn't changed much by sizing. The calculated primary hand value also showed that the ramie became more stiff after sizing.

직물의 질감을 객관화시키는 연구는 고부가가치의 의류제품을 생산하고 판매하는데 매우 중요한 요소이다. 질감은 직물의 역학적 성질과 표면상태에 따라 좌우되며, 이의 측정방법 중에서 KES-F system이 가장 객관화되어 있다. KES-F system을 이용한 표면 거칠기 측정방법은 피아노선을 굴곡 시켜 일정한 힘을 가한 상태에서 직물의 표면을 문질러 측정하므로 직물의 표면을 문질러 측정하므로 직물 표면의 잔털이 눌려진 상태여서 질감해석을 위한 정확한 측정이 어렵다. 따라서 우리는 기하학적인 직물 표면의 거칠기를 표면의 변형없이 측정 가능한 레이저 센서를 사용하였다. 한편 직물의 주로 경사ㆍ위사로 짜여져 있어 이방성 성질을 가지고 있으므로 직물을 3방향으로 측정하여 해석하였다. 측정된 신호는 FET를 이용하여 일정한 주기의 표면형태를 구하고, 표면 높낮이의 평균, 최저값과 최고값을 구하여 표면의 특성을 얻었다. 직물 표면에 존재하는 잔털은 영상처리장치를 이용하여 양을 측정하였으며 표면의 거칠기 측정결과와 비교 분석하여 레이저 센서를 이용한 비접촉식 측정방법의 오차분석 및 표면 특징을 해석하였다.

This study investigated the formability and appearance performance of 20 women's worsted fabrics. For this purpose, 10 foreign fabrics (9 Italian + 1 Japan fabrics) were prepared and 10 domestic worsted fabrics for women were made in Cheil woolen textile company for comparing with foreign fabrics. The mechanical properties of the 20 fabrics were measured using KES-FB and FAST systems; subsequently, fabric formability (F) and total appearance value (TAV) were calculated and compared with a virtual 3-D simulation silhouette by i-designer CAD system. The fabric formability of the domestic fabrics, calculated by KES-FB system, was lower than foreign fabrics, which was assumed to be caused by the stiff tactile property. The result was similar to that of the FAST system. Good wearing performance of the foreign worsted fabric was assumed to be caused by high extensibility and the compressibility of the fabrics. The TAV's of the domestic fabrics were also lower than foreign fabrics. Both the correlation between TAV and formability by the KESFB system and the correlation between TAV and formability by FAST system showed a good correlation coefficient. Fabric formability between KES-FB and FAST systems also showed a good correlation. The 3-D simulation silhouette of the foreign fabric by i-designer CAD system appeared superior to the domestic one, and assumed to be attributed to the low extensibility of the weft direction, stiff bending and high shear properties of the fabric.

The handle of fabrics including tactility and sense of visuality are closely related to the factors governing the preferences of end-users. This study shows the change of mechanical properties, thermal properties and optical properties by comparing two fabrics which are woven with circular shaped filaments and with triangular ones. The fabric mechanical characteristics required for primary hand values were evaluated with the KES-FB system. The mechanical properties measured by KES-FB system shows that fabrics made of circular filaments are greater than those made of triangular ones. The thermal properties measured by KES-F7(Thermo Labo II) system shows that the values of the initial maximum value(qmax) and the thermal conductivity(λ) are higher in the fabric made of triangular shaped ones. When the light rays tall on a surface, the fabric made of triangular filaments shows more lustrous than circular ones.

직물 표면을 문지를 때 느끼는 촉감은 여러 가지 기계적인 자극이 손 끝에 전달되어 느끼게 되므로, 직물의 표면의 특성을 분석하는 것은 매우 중요하다. 그러므로 표면을 덮고 있는 잔털의 양과 숫자를 측정하는 방법을 개발하고 촉감해석에 사용할 수 있도록 하였다. 표면의 거칠기는 비접촉으로 측정하여 잔털의 성질까지 포함된 스펙트럼을 얻었으며 FFT 분석을 통해 직물의 표면 구조의 특징과 상관되는 결과를 확인하였다. KES-F System에서 측정한 Hand Value와 비교 분석한 결과, 표면 거칠기와 잔털량과 잔털수는 객관적인 촉감해석에 중요한 요소로 사용할 수 있었다.

The purpose of this study was to determine the effect of dynamic characteristics of knitted fabrics on the clothing pressure of foundation. Five knitted fabrics of foundation were selected by different fiber types and blended ratios for the study. The dynamic characteristics of foundation wears made with five different fabrics were measured by KES-FB system method. The results of this study were as follows: 1. The tensile linearity and resilience of f1 were lower than those of other samples. While the tensile resistances of f1, f2 and f4 samples were high, the coefficients of friction of them were low. The bending rigidity and geometric roughness of f5 were higher than the others. 2. The clothing pressure of f3 all-in-one sample was the highest, and followed by f5, f4, f2 and f1, respectively. This result showed that the compression resilience affected on the clothing pressure greatly. 3. In terms of the clothing pressure by posture, the clothing pressure at $90^{\circ}$ bending posture was the highest and followed by that at standing and one-leg-up, respectively. The back part of abdomen was pressured most at $90^{\circ}$ bending posture.
