과테말라의 알타 베라파즈 지역에서 원주민들의 민속의상의 하나인 Huipil 재료로 생산되는 반투명의 백생 무명 수직물은 독특한 직조기법과 구성을 보이고 있다. 이에 대한 부분적인 연구는 O'neale 과 Osborne 등에 의하여 이루어 졌으며, 본고에서는 이들 연구를 기초로 이 지역의 Huipil 재료의 직조과정과 기법에 대하여 고찰하였다. 또한 구체적인 직물구조의 분석은 Iowa 주립대학의 직물소장품중 4점의 이지역 Huipil 재료를 실측하여 이들 각각의 전체적인 구조와 기본적인 직조방법, 그리고 무늬를 형상하는 기법에 대하여 검토하엿다. 본 고찰을 통하여 이 지역에서 생산된 Huipil은 대부분 원시적인 형태의 직조기에 의해 완성되었으며 복잡한 무늬를 짤 경우에도 보조적인 도구는 사용되지 않고 특유의 수직기법에 의해 이루어졌음을 밝혓다. 또한 Huipil의 바탕은 plain weave, gauze, 도는 brocade의 변형으로 구성되었으며 바탕과 무늬의 변화는 실의 굵기의 변화로 더욱 강조되어 독특한 효과를 나타내고 있다.

The purpose of this study is to examine the unique differentiation of dance-sports costume design and improve the professionalism of design in this field. for this, the documentary study and practical case study have been executed. the visual data in 'weave' prosperity data and a dance-sports technical book are used. The results of this study are as follows. First, dance-sports costume has the general character of dance costume, and it belongs to the category of stage costume. Second, the physical characteristics peculiar to dance-sports costume come from its specialized usage in dance-sports. Third, the design of dance-sports costume changes accordingly with the situation it is worn: exercise costume, party costume, competition costume. Fourth, arranged dance-sports costume trends since 1998. It had shown biennial changes in shilhouette.

Laminated composites are liable to fatal damage under impact load due to the fact that they have no reinforcement in the thickness direction. To overcome the inherent weakness, three dimensional (3D) textile reinforcements have drawn much interests. In this paper, impact performance of 2D and 3D textile composites has been characterized. For 2D composites, fiber bundle size and fiber pattern have been varied. For 3D composites, orthogonal woven preforms of different density and type of through-thickness fibers have been studied. To assess the damage after the impact loading, specimens were subjected to C-scan nondestuctive inspection. Compression after impact (CAI) were also conducted in order to evaluate residual compressive strength.

There are record that ancient Korean WOOl fabrics male from sheep, camel, rabbit. bear, horse. calile, raccoon dog, fox and so on. Wool fiber fabriher were also reported Kye, Gal, China, Tap Dung, Kuyu anul ram. These wool fabrics wre named amongling to their fineness and weaving method in the fabric. Technology of wool fabric weaving was developed and from Sam Kuk dynasties to to Koryo Dynasty wool fabrics were reported to weave and trade to China, Japan and Arabia. These fabrics were mainly used as clothes, rugs or blankets. In Koryo Dynasty, especially Kye Kurn was used for trading goods to China. There is another record that two thousand sheep, camels offord Koryo by Yo and Kum Dynasty. In this study, the characteristics of Korean wool fabrics will be disscussed from the literature survey of the relevant references.

The air-jet loom represents a major step in the development of shutterless weaving due to its ability to weave a wide range of yarns at high speeds. The air-jet weaving involves inserting a pre-measured length of yarn through the wraps, which is shed by means of compressed air. The analysis of air flow characteristic of the main nozzle and acceleration tube is required for improving the loom performance. In this paper, we examined the effects of the main nozzle with different acceleration tubes as well as diameters. Also, we compared the performance of a straight-type tube with a Laval-type tube and the effect of installing a suction hole on the acceleration tube.

The principal purpose of this study is focused on the fabrics used in Kaya period by investigating the imprinted fabrics on the remains of the old tomb of Dohang-ri and Jeesan-dong which were built around the late 4th century to the late 6th century. Most of the remains are plain weaved, however there is one remain that 4-end complex gauze with patterned, and the other is weaved with geometrical pattern which were plain weave with 2 · 1 twill and 3 · 1 twill. The imprinted fabrics that had twists had S twists only. Of all the fabrics that were examined, the most loose one had the density of 8 × 6/cm, the most fine fabric had the weft density of 91.8 strands/cm and the warp density cannot be counted. It is No. 416 of Doharg-ri tomb that has the highest ratio of density as 3.15. All the fabrics observed by SEM and Polarizing Microscope are hemp.

To study numerically the mechanical behaviors of advanced composite materials considering the microscopic phenomena as well as the macroscopic properties and behaviors, a multi-scale modeling and analysis by the mathematical homogenization method with the help of the finite element method(FEM) are reviewed. The hierarchical modeling strategy and the formulation are briefly described first to give some idea of the multi-scale framework. The latter half of this article focuses on the verification of the multi-scale analysis by the homogenization method in its applications to real advanced materials. The first example is the verification of the predicted macroscopic(homogenized) properties based on the microstructure of porous ceramics. In spite of the complexity of the random microstructure, the error between the predicted and the measured values was only 1%. Next, two applications to the process simulation of fiber reinforced polymer matrix composites are presented. The permeability characteristics are evaluated for sheared weave fabrics for resin transfer molding(RTM) simulation, and the thermoforming of FRTP sheet is analyzed considering the large deformation of the knit structure during the deep-draw forming was verified by comparison with the experimental results.

This study surveys the warp and weft tension differences between projectile and air-jet looms and analyses the mechanical properties of worsted fabrics for garment with relation of these loom characteristics using KES-FB system. The paper is divided by two parts. In the 1st paper, the worsted fabric is woven as 5 harness satin weave using 1/40 Nm sirofil worsted warp yarn and 1/30 Nm worsted weft yarn by projectile(Sulzer) and air-jet looms(Picanol PAT and OMNI), respectively. The weavability is also analysed by measuring warp tension variation according to the warp position and weft tension of 3 kinds of looms. The relationship between shed amount and the warp tension is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.

This research was aimed to identify the artifact type and their characteristics of the textile related materials excavated from Koryo Dynasty tombs of Hyungok-ni Danyang. Microscopy solubility test energy dispersive X-ray spectroscopy(EDS) and fourier transform infrared spectroscopy (FT-IR) fabric density test were used for the identification and when necessary standard samples were made in order to compare its characteristics with hose of the original artifact, the result indicated that the artifacts included both textile and paper. Artifacts from Burial 14 were comprised of textile fragments FT-IR and the solubility test conducted on the artifact indicated that the textiles were made with ramie woven with plain weave technique in a fairly loose fabric density. Rest of the artifacts were all comprised of paper.
