The kind and the use of the fabrics for crown manufacture in the Baekje period has been studied by characterizing the imprinted fabrics on the crowns and the diadem ornaments from the old tomb. The contact region with the skin inside of the crown and the region between the bark of white birch and the gilt bronze openwork plates contained fabrics. The fabrics used in the gilt-bronze crown were all plain weave silk except that of Yongwonri tomb where loosely woven thin tabby was used. There have been 4-types of iron framed diadem of the Baekje, which comprise the inverted triangle-shaped diadem only with iron frame, the diadem with gold plate ornament in the iron frame, the diadem decorated with mica plate and gold plate, and the diadem with silver ornament in the iron frame. The fabrics used in the triangle shaped iron frame diadem include plain weave silk, irregular plain woven silk, thin tabby, complex silk gauze, twill weave on plain ground, and warp-faced compound weave. The iron frames were wrapped with the fabrics from one layer up to three layers, and the iron diadem was covered with one later of loosely woven textile such as irregular plain woven silk, thin tabby, and complex silk gauze. But in case of decorating the iron diadem with gold Plate ornaments, multiple layers of fabric were used to sustain the weight of the ornaments. The fabrics in the iron diadem frame were sewed with running stitch, overedge stitch or hemming stitch, diagonal hemming stitch, half back stitch), and overcast stitch.

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.

This paper proposes a numerical optimization method to design the mesoscale architecture of textile composite for simultaneously enhancing mechanical and thermal properties, which compete with each other making it difficult to design intuitively. The base cell of the periodic warp and fill yarn system is served as the design space, and optimal fibre yarn geometries are found by solving the optimization problem through the proposed method. With the help of homogenization method, analytical formulae for the effective material properties as functions of the geometry parameters of plain-woven textile composites were derived, and they are used to form the inverse homogenization method to establish the design problem. These modules are then put together to form a multiobjective optimization problem, which is formulated in such a way that the optimal design depends on the weight factors predetermined by the user based on the stiffness and thermal terms in the objective function. Numerical examples illustrate that the developed method can achieve reasonable designs in terms of fibre yarn paths and geometries.

The mechanics of woven fabric-based laminated composites is complex. Then, many researchers have studied woven fabric CFRP materials but fracture resistance behaviors for composites have not been still standardized. It also shows the different behavior according to load and fiber direction. Therefore, there is a need to consider fracture resistance behavior in conformity with load and fiber direction at designing structure using woven CFRP materials. In this study, therefore, the tensile strength and resistance for plain-weave CFRP composite materials were investigated under various different angle condition(load to fiber angle: $0^{\circ}$, $15^{\circ}$, $30^{\circ}$, $45^{\circ}$). Tensile strength and fracture toughness tests were carried out under mode I transverse crack opening load by using compact tension specimens.

Since the early 2000s, various fashion design products that use 3D printing technology have constantly been introduced to the fashion industry. However, given the nature of 3D printing technology, the flexible characteristics of material of textile fabrics is yet to be achieved. The aim of this study is to develop the optimal design conditions for production of flexible and elastic 3D printing fabric structure based on plain weave, which is the basic structure in fabric weaving using SLS 3D printing technology. As a the result this study aims to utilize appropriate design conditions as basic data for future study of flexible fashion product design such as textile material. Weaving structural design using 3D printing is based on the basic plain weave, and the warp & weft thickness of 4mm, 3mm, 2mm, 1.5mm, 1mm, and 0.7mm as expressed in Rhino 6.0 CAD software program for making a 3D model of size $1800mm{\times}180mm$ each. The completed 3D digital design work was then applied to the EOS SLS Machine through Maker ware, a program for 3D printer output, using polyamide 12 material which has a rigid durability strength, and the final results obtained through bending flexibility tests. In conclusion, when designing the fabric structure design in 3D printing using SLS method through application of polyamide 12 material, the thickness of 1 mm presented the optimal condition in order to design a durable digital textile structure with flexibility and elasticity of the 3D printing result.

This study attempts to examine compound weave among silk fabrics of Cho-Sun Dynasty. These silk fabrics have colorful patterns. They can be classified into two types by their texture structure one is called polychrome woven silk of which structure is plain or twill fabric : another is called satan damask of which structure is stain fabric. Their texture structure consist of warp and weft. In addition. there are other types of warp and weft for pattern structure ; various twill structures were used for patterns. A variety of colorful threads, including gold and silver ones. are used fur patterns in them. The brocaded-type fabric was primarily developed during Won Era of China. It was most developed in Ko-Rye Kingdom. During that era flat strip was used the most but its length was usually not long enough to finish one pattern. However, wrapped thread was increasingly used during the middle and later period of Cho-Sun Dynasty due to the development of weaving technology for gold thread. The brocaded-type fabric was produced in Korea and it was also Imported from China according to some record. There are some domestic empirical documents that show the names of imported Satin Samite, Brocaded satin and these are good evidence to prove the nationwide use of the cloth during Cho-Sun Dynasty. The density ratio of warp and weft is almost same except Samite in the third and Satin with flower motif in the second period is most density among them. C·F of Brocaded satin with Mang motif in the third period values the highest price. Brocaded satin, used with both gold and silver threads, is thickest.

The purpose of this study was to determine the pore size distributions (PSDs) of polyester woven fabrics by using liquid extraction method. Three types of PSDs-percent PSD, PSD per unit area of sample and PSD per unit weight of sample-were evaluated. Plain, twill and satin polyester fabrics with various fabric counts were used as specimens. Results showed that the interyarn PSDs reflected the fabric characteristics such as the fabric count and the weave type and the intrayarn PSDs reflected the thread characteristics such as the number of fibers, the fiber diameter, the thread diameter and the thread twist. Of three types of PSDs, the PSD per unit area of sample best reflect fabric and thread characteritics. As the fabric count decreased, rc increased and interyarn pore volume increased. The PSDs were skewed to the small pore sizes and the pore volumes decreased in the order of plain> twill> satin. As the number of fibers, the fiber diameter and the thread twist decreased, the intrayarn pore volumes were increased.

In this paper, the fabric specimen undergoes repeated laundering under given condition. After this cyclic laundering was applied, the crease recoveries of the specimen were measured using shirley crease revovery tester in order to evaluate the effect of factors at given condition during crease deformation. 5 samples of grey plain cloth were desized, alkali-scoured, bleached, whased with water, and air-dried. All tests were made on samples preconditioned to $65\%\;RH\;and\;20^{\circ}C$. The experimental results were analysed statistically to relate crease recoveries and the properties of smaples, recovery periods (time) of crease. Furthermore, the crease recoveries of core-spun yarn woven fabrics were discussed in comparison with those values for $100\%$ combed cotton yarn woven fabric and $65\%$ polyester $35\%$ carded cotton blended yarn woven fabric. The results obtained are as follows; 1. Regardless of materials, remarkable decrease are observed in crease recoveries about 1-5 cycles of the repeated laundering, but slack decrease are observed in crease recoveries after 5 cycle of the re-peated laundering. 2. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to recovery periods (t) of crease as follows; log$\alpha$=0.01415 log t+2.1168 ($r^2=0.94$) 3. Core-spun yarn woven fabrics were superior to $100\%$ combed cotton yarn woven fabrics and $65\%$ polyester $35\%$ carded cotton blended yarn woven fabric in crease recoveries. 4. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to cover factor (CF), thickness (T) at pressure 0.5 $gf/cm^2$, weight (W) as follows; log$\alpha$=-0.3482 log CF-0.4924 log T-0.4727 W+2.4243 ($r^2=0.88$) 5. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to 2HB/B, 2HB/W, $\sqrt[3]{B/W}$, WC/T which are concerning to formation of weared clothes and bending Iran formation behavior as follows: log $\alpha$=0.0091 2HB/B+0.4667 2HB/W+0.0185 $\sqrt[3]{B/W}$+0.0114 WC/T+1.8433 ($r^2=0.86$)

In this paper, elastic behavior of woven fabric composites with various fiber yarn structure were predicted through a theoretical calculation model. A representative volume elements (RVE) that can represent the mechanical properties of the woven composites were selected and crimp angle of the weave yarn was defined by several sinusoidal functions. The effective material properties of the woven composite such as young's modulus, shear modulus and poisson's ratio was predicted by classical laminate theory (CLT). The fiber volume fractions were calculated according to the shape and pattern (plain, twill weave) of the fiber yarn, and the elastic behavior of each woven composite was obtained through a theoretical calculation model. Also, to verify the theoretical predictions, woven composite specimens of plain and twill weave were fabricated by vacuum assisted resin transfer molding (VARTM) process and then mechanical test was conducted. As a results, a good correlation between theoretical and experimental results for the elastic behavior of woven composites could be achieved.
