This study examines 74 pieces of textiles of Daegaya found in the Jeesan-dong Tomb and Saeng-cho Tomb, and analyzes their characteristics and weaving techniques. Dagaya is known to have produced ramie and hemp from bast fibers. The hemp textiles were all woven in plain weave, and the ramie textiles were woven either in plain weave or plain braid. The ramie textiles were slightly more dense compared to the hemp textiles, however, both had average densities between 0.92 to 0.93, showing that they are balanced plain weave textiles. It was also found that S twist threads were used in the production of the hemp and ramie textiles. The dyed textiles on iron remains were found to be the oldest textiles to use dying techniques for patterns. Silk textiles were woven in plain weave, twill weave, and leno weave. All of the silk were made with non-twisted thread. The densities were between 30 to 58.3 and the the density rates were 1.0 to 2.5 for plain weave silk, this showed that varieties of plain weaver created by different densities of warp and well. The average density of cho was $53.4{\times}22.5/cm^2$ the density rate was about 2.40, therefore warp was woven more dense compared to the weft. There were degummed and raw silk used in silk textiles, but most of them were found to be degummed thread.

In general, laminate effective orthotropic thermal conductivities are dependent on fiber and matrix material properties, fiber volume fraction and fabric geometric parameters. This paper deals with the predicting method of the transverse and the in-plane thermal conductivities of plain weave fabric composites based on the three dimensional series-parallel thermal resistance network. Thermal resistance network was applied to unit cell model that characterizes the periodically repeated pattern of plain weave. Also, an experiment apparatus is setup to measure the thermal conductivities of composite material. The numerical and experimental results of carbon/epoxy plain weave are compared.

Carbon nanotubes (CNTs) have shown great potential for the reinforcement of polymers or fiber-reinforced composites. In this study, mechanical properties of multi-walled carbon nanotube (MWNT)-filled plain-weave glass/epoxy composites intended for use in radar absorbing structures were evaluated with regard to filler loading, microstructure, and fiber volume fraction. The plain-weave composites containing MWNTs exhibited improved matrix-dominant and interlaminar fracture-related properties, that is, compressive and interlaminar shear strength. This is attributed to strengthening of the matrix rich region and the interface between glass yarns by the MWNTs. However, tensile properties were only slightly affected by the addition of MWNTs, as they are fiber-dominant properties.

In this study, a new constitutive model has been developed to predict the elastic behavior of plain weave textile composites, using the finite element (FE) method. The geometric conditions and basic assumptions of this model are based on the basics of a continuum theory developed for the plane curved composites. In this model, the mechanical properties of the weave region and pure matrix region is calculated separately and then imported for the FE analysis. This new constitutive model is used to implement the mechanical properties of weave region in the representative volume element (RVE). The constitutive relations are implemented as user-material subroutine code (UMAT) in ABAQUS® FE software. The results of FE analysis have been compared with experimental results and other data available in the literature. These comparisons confirmed the capability of the presented model for the prediction of effective elastic properties of plain weave fabric composites.

A study on shrinkage after wash of several cotton textiles for embroidery on the market produced the following results : 1. As the wash temperature rises, the shrinkage increases. 2. Shrinkage of sample 2 and 3, variant weave of plain weave, is greatest, and the next is that of sample 1, a variant of plain weave. Shrinkage of sample 4 and 6, which have more floating, is small. 3. In the wash, thickness of the textile increases with rise of the temperature. 4. Strength of the textile increases with rise of the wash temperature.

This study analyzed the characteristics of Korean traditional plain weave excavated from Sang-go period to Joseon Dynasty. To do this, this study classified the Korean traditional plain weave into fiber types(cotton, hemp & ramie, plain weaved silk), analyzed and compared the thickness, twist type of yarns and density by times. First, in characteristics of cotton, the average and maximum density of Joseon Dynasty were higher than those of Goryeo, twist type was mainly s-twist and the density of warp was higher than that of weft. Second, the maximum density of hemp & ramie was found in era of Three Kingdoms of Korea. In common characteristics of hemp & ramie, twist type was mainly s-twist(sometimes non-twist) to the Three Kingdoms of Korea and was changed into non-twist from the Goryeo. The density of warp was higher than that of weft in common. Generally, the average density of ramie was higher than that of hemp. Third, in the characteristics of plain weaved silk, twist type was mainly non-twist(sometimes s and z-twist) from Sang-go period to Joseon Dynasty. Warp-faced ribbed tabby was excavated in Goryeo, the average density of warp-faced ribbed tabby was higher than that of other fiber types plain weave. Generally, in all fiber types, the density of warp was higher than that of weft.

The optimum fabric design plan is recently needed with the relevant fabric shrinkage in dyeing and finishing processes for the various sensible fabrics for garment. For responding this need, the difference of fabric design plan such as fabric density, yarn count and finishing shrinkage has to be surveyed with weaving looms such as water jet, air-jet and rapier looms, and also has to be analysed with weave pattern such as plain, twill and satin according to the fabric manufacturers. Therefore, in this study, 420 polyester weave pattern sheets are collected from 5 fabric manufacturers, and the weave density coefficients of these fabrics are calculated using yarn count, fabric density and 1 repeat weave pattern. These weave density coefficients are analysed according to the fabric manufacturers, weaving looms and various weave patterns. And also the weave density coefficients of 420 polyester fabrics are analysed with finishing shrinkage according to the fabric manufacturers and various weave patterns such as plain, twill and satin fabrics.

The purpose of this study is to analyze the subjective fabric hand of sleepwear fabrics, and to assist in developing sleepwear fabrics that offer maximum comfort in wearing sensation. In general, the respondents noted that sleepwear fabrics made with polyester had better tactile sensation than those made with cotton, while satin weave fabrics felt better than plain weave fabrics. As regards the difference in fabric hand according to gender, female students responded with more receptiveness and sensitivity than male students in the category of woven fabric evaluation. As regards the same textile materials, the evaluations of female students and male students differed in fabric hand descriptors, particularly for the evaluation on cotton fabrics. Male students responded that both plain weave fabrics and satin weave fabrics were stiff while female students replied that satin weave fabrics had better tactile sensation.

본 논문에서는 평직복합재료에 있어서 섬유다발의 위상각 변화와 적층수에 따른 등가탄성계수의 저 균일도 문제를 연구하였다. 각 적층수에 따라 단순히 적층된 모델과 무한히 반복되어 적층된 모델에 대해 단위구조 해석을 수행하였다. 수치실험을 통해 탄성계수를 계산하였고, 이를 통계적으로 처리하였다. 계산 결과 평직복합재료의 등가탄성계수는 위상각과 적층수의 변화에 크게 의존하며 임의의 조합에 대하여 그 분포양상은 큰 차이를 보였으나, 전반적으로 적층수가 증가함에 따라 균일도가 높아지는 경향을 보였다.
