This research was analyzed regarding comparing features of expressions between clothes in movie, , and cyber clothes that were made by Marvelous Designer2 which is a design CAD. This research was studied to experiment an expressing possibility of clothes simulation software which was developed currently. Therefore, we picked clothes that are good at movement and detail in the movie. The dress theory of the renaissance which is the period background of movie, was considered and studied as pattern, silhouette, material, color, detail and animation. The movie's dresses are made with 3D virtual and compared so 3D virtual clothes's benefits and weaknesses can be analyzed. As a result, we found that 3D virtual dress can show the real movie's feature accordingly with current developed IT standard. This will assist a development in fashion industry and become a new indicator for 3D movie clothing.

Herein, a highly elastic e-textile band with a two-wire transmission line was designed and fabricated for smart clothing applications. A conductive yarn with a very uniform low electrical resistance of 0.0357 Ω/cm was developed and used for the signal and ground lines. To control the elasticity of the e-textile band, spandex yarns were added in the warp direction during knitting and the tension was adjusted. As the length of the e-textile band increased, its RF performance deteriorated. Furthermore, the frequency corresponding to -3 dB S21 was lower in the 30% stretched band than in the unstretched band. For the e-textile bands with lengths 10, 50, and 100 cm, the frequencies corresponding to -3 dB S21 were 107.77, 24.56, and 13.02 MHz when not stretched, and 88.74, 22.02, and 12.60 MHz when stretched by 30%. The fabricated bands were flatter, more flexible, and more elastic than transmission line cables; thus, they can be easily integrated into wearables and smart clothing. However, to increase RF performance and achieve optimum utilization, future studies must focus on the fabrication of transmission lines with lower resistance and reduced distance between the signal and ground lines, and thus the number of transmission lines can be increased.

This study aims to analyze short sleeve cycling tops from three brands for a change in garment fit and pressure depending on the static and cycling postures. To this end, it used a 3D virtual garment system to virtualize the garments. Further, a cross-section of the 3D virtual garment data was obtained, and the space length was measured in the design-X program to prove the objectivity of the 3D virtual garment. The results indicated that three brands had a large space length at the front than the back because of the bent posture in cycling. Therefore, appropriate ease was required for the waist and abdomen. Although there were various cutting lines of the bodice panel by brand, the design of the cutting lines should consider the changes in the surface to reflect the bent posture in cycling. The results of this experiment confirmed that the wrinkles present in the 3D virtual garment were reflected in the cross-section and that the space length was small in the high-stress area, as shown in red. Therefore, it was proven the stress of the 3D virtual garment could be used for 3D virtual garment evaluation.

Polyesteramide(PEA) has been synthesized with different molar ratio of 6-aminocaproic acid(ACA) and oligo butylene terephthalate(OBT) prepared from Dimethyl terephthalate(DMT) and 1, 4-butanediol(BD) by the melt polymerization. Oligomer and polymer molecular structure were characterized by IR spectra, H'-NMR spectra. Also the thermal properties were examined by thermogravimetric analysis(TGA) and differential scanning calorimetry(DSC). DSC and TGA results exhibited that the$ T_m$ s were detectable in the vicinity of $170-220^{\circ}C$ and the Ta's were detectable in the vicinity of $380-390^{\circ}C$ . X-ray diffraction analysis results show that the synthesized polyesteramide has high degree of crystallinity.

This study was carried out to analyse body configuration and to observe any space between skin and foundation. A special 3D scanner was used to analyze this foundation. Experimental foundations were brassiere, girdle, and all-in-one. Four subjects volunteered, each subject was scanned while wearing foundation and not wearing foundation. Body shape variations were analyzed with an Auto CAD and ScanWax program which analyzes cross section of the skin surface to look for any changes. Height was increased all parts of body, circumference was increased in breast and bust while wearing the foundation. The hip thickness was not increased with wearing the foundation. Therefore this foundation makes people have a different appearance due to unexpected body shape variations. The effects of this foundation should be classified by observing height, circumference, and thickness changes in the body.

For many years researchers have been attempting to establish the relations among the preparation history, structure and properties of ceramics. In this study, the strength property of $Al_2O_3$ ceramics with components and giudes of the textile machinery was investigated. The optimized conditions of ressureless sintering were investigated in order to obtain the maximum strength of $Al_2O_3$ ceramics for using at the textile machinery. As the sintering conditions, $1,400{\sim}1,700^{\circ}C$ of temperatures and $30{\sim}150$ minutes of times were applied. Three-point bending test was conducted on the sintered materials to obtain the strength property. From test results, the optimum sintering temperature has $1,600^{\circ}C$. And the optimum sintering time in $1,600^{\circ}C$ has about 100 minutes.

Sodium cellulose carbonate (CC-Na) dissolved in $8.5\;wt\%$ NaOH/ZnO (100/2-3, w/w) aqueous solution was spun into some acidic coagulant systems. Diameter of regenerated cellulose fibers obtained was in the range of $15-50\;{\mu}m$. Serrated or circular cross sectional views were obtained by controlling salt concentration or acidity in the acid/salt/water coagulant systems. Velocity ratio of take-up to spinning was controlled up to 4/1 with increasing spinning velocity from 5 to 40 m/min. Skin structure of was developed at lower acidity or higher concentration of coagulants. Fineness, tenacity and elongation of the regenerated cellulose fibers were in the range of 1.5-27 denier, 1.2-2.2 g/d, and $8-11.3\;\%$, respectively. All of CC-Na and cellulose fibers spun from CC-Na exhibited cellulose II crystalline structure. Crystallinity index was increased with increasing take-up speed.

This paper investigates the physical properties of aramid and aramid/nylon hybrid air jet textured filaments for protective garments relative to ATY nozzle diameters. Three types of para-aramids(840d, 1,000d, 1,500d) and nylon(420d) filaments were prepared; in addition, 840d aramid/420d nylon and three kinds of aramid filaments were texturized with a variation of air jet nozzle diameters(0.6, 0.75, 1 and 1.2 mm) on the AIKI air jet texturing machine. The measured physical properties of 16 specimens are as follows. The linear densities of aramid and aramid/nylon hybrid ATY increased with a larger nozzle diameter. The tenacity and initial modulus of aramid and hybrid ATY linearly decreased with a larger nozzle diameter; in addition, the breaking strain increased with the nozzle diameter. The dry and wet thermal shrinkage of hybrid ATY increased with a larger nozzle diameter from 0.6 mm to 1 mm and then decreased at a nozzle diameter of 1.2 mm (which seems to be a critical diameter). The wet and dry thermal shrinkage of aramid/nylon hybrid ATY are influenced by the nylon part of the hybrid yarns because the wet and dry thermal shrinkages of aramid ATY are less than 0.2%. The instabilities of aramid and aramid/nylon hybrid ATY were not influenced by the air jet nozzle diameter; however, they increased with the linear density of ATY.

The industry-wide development of digital technologies has also affected the textile and fashion industries immensely. The applications of 3D technology, virtual reality, and/or augmented reality systems have helped to create novel fashion brands based on the marriage of IT and textile/fashion industries. 3D digital virtual clothing systems have been developed to help the textile and fashion industries in terms of the planning, manufacturing, marketing and sales sectors. So far, most of the development effort for the 3d virtual clothing systems has been focused on the woven fabrics. The characteristics of woven fabrics differ from those of knitted fabric. Since the physical structures and mechanical properties of the knitted fabrics are definitely different from those of woven fabrics, the simulation process for the knitted fabrics should follow different approaches. The loops in a knitted fabric deform easily. The deformation results in a readily stretchable fabric appearance. Cloth simulation mostly employs models that approximate the mechanical properties of linear elastic planes. This simulation scheme does not, however, describe well enough the behavior of knitted fabrics, which deviate largely from the linear isotropic material characteristics. This study aims at characterizing the tensile deformation and surface textures of a knitted fabric product. Tensile deformation curves for the wale, course, and bias direction are analyzed. The surface texture of the knitted fabric is analyzed by using a 3-dimensional scanning device.

국제회계기준위원회(IASB)에서 규정한 R&D 산업은 다양한 분야에서 '연구'와 '개발'을 동시에 진행하는 3차 산업에 해당한다. R&D 산업과 관련한 기존 정성적 연구들은 공간군집 사례들을 기반으로 분류한 클러스터 유형 중 하나인 하이테크 혁신 클러스터로 취급하여 분석한다(Coe et al., 2007). 그러나 이는 다양한 R&D 산업의 공간군집 사례들을 일반화하는데 그쳤으며, 특히 클러스터 형성 과정에서 시간의 흐름을 고려하지 않은 R&D 클러스터가 시공간적으로 유의미한 것인지 알 수 없다. 이에 본 연구는 기존 공간적인 혹은 시간적인 측면만을 강조하는 클러스터 분석의 한계를 인식하고, 섬유 및 의복 제조업의 비교를 통해 R&D 시공간 클러스터를 탐색해본다. 연구방법으로는 시공간 클러스터의 발견 및 위치탐색을 위해 시공간 K-함수와 시공간 스캔통계를 이용하였다. 그 결과, R&D는 공간적 측면만 고려한 분석에서는 유의미한 클러스터가 발견되었지만, 공간적 분포와 시간적 흐름을 동시에 고려한 시공간 클러스터는 발견되지 않았다. 즉, 시간에 따른 R&D의 신설 과정은 이미 존재하는 R&D의 공간적 위치와 독립적인 것으로 나타났다. 반면 섬유 및 의복 제조업은 공간과 시공간 클러스터 모두 유의미한 클러스터를 발견했다.
