In this paper, various tow parameters such as equivalent tow thickness, amplitude of longitudinal tow and tow intervals were investigated and compared with each other by using microscopic observation to find out the exact deformation patterns between both directions of the fabric structure (Longitudinal and Transverse Directions). Specimens for the observation were taken from draped helmet which is made of fabric composite (Five Harness Satin Weave). From the observation results, it was found that there are different deformation pattern between tow directions and effect of geometric condition on the deformation of the fabric materials during draping process was verified.

The purpose of this study was to investigate how the weave type, yarn twist fabric count and fiber content of the worsted fabrics affect the subjective sensation of the hand. Thirty worsted fabrics that were mainly used for the spring and fall ladies'suits at national brands were selected. Variables were such as four different kinds of weave types, plain, twill, satin and decorative; two levels of yarn twist, normal and high; various fabric counts; two different fiber contents, pure wool and Lycra contained. Image analysis and wavelet transform techniques were used to quantify the surface fiber, For surface characteristics, MIU, MMD and SMD were measured by KES-FB system. The Questionnaires with 23 adjectives were used for the subjective hand evaluation. Panels were So specialists of fashion or fabric designers and merchandizers. By Factor Analysis, six factors that represent the subjective hand were extracted. The relationship between these factors and structural variables were analyzed. Yarn twist was significantly related to the surface characteristics and resilience. Weave structure affected surface characteristics, volume/warm-cool feeling and resilience. Fabric counts showed relations with volume/warm-cool feeling and the fiber contents with volume/warm-cool feeling, resilience and elastic properties. MIU, MMD and SMD showed no relations with the surface fibers. Subjective sensation of surface characteristics was affected by SMD and surface fibers.

This paper presents the microscopic observation results from the picture frame test using five-harness satin weave fabric composite. Aligned and misaligned specimens are observed to verify the exact tow deformation pattern such as tow interval and change in tow amplitude. To observe the micro-deformation of the fabric structure, appropriate specimens from picture frame test are sectioned and observed under the microscope. From the observation results, it is found that a picture frame test with a misaligned fibre orientation angle shows large differences in deformation between tensile and compressive tow directions.

This study emphasizes on the characteristics of the excavated fabrics from the tomb of Kimwhoak in the late 16th and early 17th centuries. All of 118 kinds of fabrics are used in excavated costume from the tomb of Kimwhoak. Classified by its materials, it is divided into small groups as follows: 63 pieces of spun silk tabby(53.6%), 14 of spun yarn silk(11.9%), 13 of thin filament silk tabby(11.0%), 8 of thin silk tabby(6.8%), 4 of satin without pattern(3.4%), 3 of filament silk tabby(2.5%), 3 of twill without pattern(2.5%), 2 of satin damask(1.7%), 2 of mixture fabric with silk and cotton(1.7%), and 2 of ramie fabric(1.7%), 1 of simple gauze without pattern(0.8%), 1 of damask with supplementary gold thread(0.8), 1 of cotton(0.8%), 1 of etc(0.8%). Classified by ways of weaving: 106 pieces of plain weave(89%), 6 of satin weave(5%), 3 of twill weave (3%), 1 of gauze weave(1%), 1 of compound weave(1%) and etc(1%). In point of patterns, the most of textiles are without pattern, there are only two of them are patterned textile. such as lotus patterns with vine, peony patterns with vine. Their patterns are very similar to those of other tombs in the same age.

본 연구는 지속적인 의류 환경 문제에 대응하기 위해, 지속 가능한 대안인 업사이클링(Upcycling)을 3D 의류 시뮬레이션 프로그램 Z-weave를 사용하여 해결책을 모색해 보는데 그 목적이 있다. 업사이클링 제품은 한정된 소재와 자원으로 샘플 제작이 어렵고, 폐의류들로 바로 완성품을 제작해야 한다는 한계점이 있다. 이러한 제약을 극복하기 위해 3D 의류 시뮬레이션 프로그램을 도입해 폐의류의 한정된 자원을 효과적으로 활용하고자 한다. 본 연구의 목표는 Z-weave를 통해 생성된 가상공간에서의 의류 원단과 현실 원단의 유사도를 확인하고, 이를 통해 실제 패션 산업에서의 활용 가능성을 평가하는 것이다. 연구 방법은 실제 작품과 유사하게 표현하기 위해 Z-weave 프로그램 안에서 물성을 조절해 실제 소재와 비교하고 전공자들을 대상으로 설문 조사와 인터뷰를 시행하였다. 이로써 Z-weave 프로그램의 패션업계에서 활용 가능성과 잠재적 한계점을 알아보고자 한다. 이 연구는 디지털 기술이 패션 산업에 미치는 영향에 관한 내용과 3D 의류 시뮬레이션 프로그램이 지속 가능한 패션 제작에 어떻게 활용될 수 있는지를 알아보고자 한다.

The purpose of this study was to investigate the difference of cotton fabric texture perceived between on-line(screening fabric) and off-line(real fabric), and to analyze fabric characteristics having an effect on the difference. The similarity of 55 various cotton fabrics perceived between on-line and on-line were measured showing simultaneously real fabrics and screening fabrics by 7-scale questionnaire. And the characteristics of cotton fabrics such as weave structure, thickness, weight, fabric density, stiffness, Hunter's L, a, b, and hue were measured. Cotton fabrics were classified into 3 groups by extent of similarity. There were no significant differences in weft density, stiffness, Hunter's L, a, b, and hue among 3 groups. But there were significant differences in weave structure, thickness, weight, warp density, and difference of warp ＆ weft density. The fabrics having large similarity were thick and heavy, had small warp density and difference of warp ＆ weft density, and distinct surface texture. The group having medium similarity included fabrics of medium thickness and weight, having weak surface texture, large warp density and difference of warp ＆ weft density. The group having small similarity, which the differences between on-line and off-line were large, included thin and light fabrics having smooth surface and large warp density and difference of warp ＆ weft density.

The Purpose of this study is to investigate the jeogori included in the buddist statue in 1748. The jeogori was similar in shape to excavated costume of Andong Kwon, Papyung Yoon, and Chungyeongunju in 18th century. This jeogori was useful to estimate the interesting process of shape change of jeogori in 18th century. Four different silk fabrics were used in the jeogori. Outer fabrics were satin weave with floral, lattice strip, dragon, and cloud patterns. The ground area was 5-harness warp faced satin and the patterned area was 5-harness filling faced satin. An inner fabric was simple plain weave. Warp and filling yarns of all fabrics in this jeogori had no twist.

To understand the tensile behaviors of GFRP at low temperature, three types of specimen have been used in this study. Tensile properties and fracture mechanisms for three orthogonal orientations of plain weave glass fabric reinforced epoxy resin laminate were investigated at temperature range of about -30 to $15^{\circ}C$. The tensile properties of axial and edge type specimen decrease slightly with decreasing temperature to $-20^{\circ}C$. However, at $-30^{\circ}C$ the decreases in the tensile properties increased considerably. Below $-20^{\circ}C$, thickness type specimen showed a marked decreases in the tensile properties. It was obvious that the fracture manner of thickness type specimen was adhesive failure at above $-10^{\circ}C$ and a mixed adhesive and cohesive failure at below $-20^{\circ}C$.

The anisotropic mechanical properties were measured for the three orthogonal orientations of plain weave glass fabric reinforced epoxy resin laminate. In tensile and flexural tests, axial and edge type specimens failed by pull-out of warp and fill yarns, respectively. In contrast, the thickness type specimens failed by adhesive failure process. Longitudinal cracking occurred in several of the edge type specimens during tensile test. That cracking caused pop-in in the stress-strain curve. Defects induced by improper coupon machining caused that cracking.
