The purpose of this study is to develope a design prototype of 'Smart Battle Jacket' for the future soldier system. Future battle field is supposed to be the place where the information is the most important. Future soldiers are also supposed to get digital devices to have more possibility of survival in the battle field. To design the smart battle jacket that has digital devices inside, it's needed to forecast the body sizes and shape of the future soldiers, to research the human bodies and movements, and to study the functions of the digital devices and the relationship between the bodies and the devices. The usability of the 1st model for the Smart battle jacket had been tested, and the model had been corrected by the results from the test. After all, a smart battle jacket design prototype for the future soldier system has been developed.

This study aims to develop electromyography (EMG) textile electrodes and assess their performance and signal stability by examining variations in layer count and fabric types. We fabricated the electrodes through layering and pressing techniques, focusing on configurations with different layer counts (Layer-0, Layer-1, and Layer-2). Our findings indicate that layer presence significantly influences muscle activation measurements, with enhanced performance correlated with increased layer numbers. Subsequently, we created electrodes from five distinct fabrics (neoprene, spandex cushion, 100% polyester, nylon spandex, and cotton canvas), each maintaining a Layer-2 structure. In performance tests, nylon spandex fabric, particularly heavier variants, outperformed others, while the spandex cushion electrodes showed superior stability in muscle activation signal acquisition. This research elucidates the connection between electrode performance and factors like layer number and electrode-skin contact area. It suggests a novel approach to electrode design, focusing on layer properties and targeted pressure application on specific sensor areas, rather than uniformly increasing sleeve pressure.

In order to reflect emotion and sensibility of consumers to textile pattern design, the effect of design elements of block stripe pattern on sensitivity was investigated. The stimuli were manipulated with 4 design elements of value difference (3 levels), arrangement (2 levels), width (2 levels) and interval (3 levels). Among the 36 combinations, 27 stimuli, which showed independent sensibility results in the pretest, were adopted as final stimuli. Male and female university students (n=30) evaluated each sensibility subjectively using a questionnaire developed for this study. The effect of design elements on 12 sensibility dimensions drawn by factor analysis and the relationships between the physical quantities of each stimulus and the sensibilities were investigated. As the results of ANOVA for the effect of design elements on sensibility, there were more significant differences in sensibility in the orders of value difference, interval, width, and arrangement. The value difference showed the highest explanatory power. Looking at the sensibility differences according to the level of design elements, the narrower the width of the stripe, the more 'humble', 'clean', 'modern', 'simple', and 'comfortable', and the narrower the interval between stripes, the more 'impressive' and 'conservative' The smaller the value difference, the more 'luxurious', 'modern', 'humble', 'simple', 'soft', and 'clean'. Regression models to predict the 12 sensibilities showed higher values of goodness of fit except 'conservative', 'casual' and 'modern', which were all over 0.6. Based on these results, 2 design prototypes reflecting consumer's sensibility were presented.

Interest in bio-signal monitoring of wearable devices is increasing significantly as the next generation needs to develop new devices to dominate the global market of the information and communication technology industry. Accordingly, this research developed a resistive textile strain sensor through a wetting process in a single-wall carbon nanotube dispersion solution using an E-Band with low hysteresis. To measure the resistance signal in the E-Band to which electrical conductivity is applied, a universal material tester, an Arduino, and LCR meters that are microcontroller units were used to measure the resistance change according to the tensile change. To effectively handle various noises generated due to the characteristics of the fabric textile strain sensor, the filter performance of the sensor was evaluated using the moving average filter, Savitsky-Golay filter, and intermediate filters of signal processing. As a result, the reliability of the filtering result of the moving average filter was at least 89.82% with a maximum of 97.87%, and moving average filtering was suitable as the noise filtering method of the textile strain sensor.

This study aims to create a highly conductive E-textile made by recycling PET with a Dip-coating process. PET fiber with hydrophobic properties is characterized by the difficulty in imparting great conductivity when both Virgin and Recycled are made of electronic fibers through a Dip-coating process. To advance the effectiveness of the Dip-coating process, a sample made of recycled PET was surface modified for 50 w 5 minutes and 10 minutes employing a Covance-2mprfq model from FEMTO SCIENCE. After that, the sample was immersed in an SWCNT dispersion (.1 wt%, Carbon Co., Ltd.) for 5 minutes, and then dip coating was conducted to allow the solution to permeate well into the sample through a padder (DAELIM lab). After the procedure was completed, the resistance measurement was measured with a multimeter at both ends and then accurately remeasured with a wider electrode. As a result of this contemplation, it was affirmed that great conductivity might be given through an impregnation process through the plasma surface modification. When the surface modification was performed for 10 minutes, the resistance was reduced by up to 2.880 times. Dependent on the results of this research, E-fibers employed in the smart wearable sector can also be made of recycled materials, improving smart wearable products that can save oil resources and reduce carbon emissions.

The purposes of this study are to evaluate mechanical properties and sensibility of tencel jacquard fabrics treated with ginkgo biloba extract and silicon softener, and to contribute to the research and development of the bedclothes made of the tencel jacquard fabrics. Mechanical properties and objective fabric hand evaluation were measured by using KES-FB system. Subjective sensibilities such as sensory, touch, and purchasing preference were estimated by using blind field test. The tensile properties such as EM, WT, and RT of tencel jacquard fabrics treated with ginkgo biloba extract and silicon softener showed increase. Bending properties and shear properties were decreased, but compression properties were increased compared to untreated fabric. With ginkgo biloba extract and silicon softener treatment, thickness and weight were increased. Therefore, tencel jacquard fabrics became more stretchable, softer, and bulkier than untreated fabrics. Consequently, THV of tencel jacquard fabrics treated with ginkgo biloba extract and silicon softener were increased. When fabrics were treated sequentially with ginkgo biloba extract and silicon softener, fabrics were estimated softer, more flexible, and bulkier than untreated fabrics. Also, tencel jacquard fabrics treated with ginkgo biloba extract and silicon softener were estimated to have good touch and preference.

Current global textiles and fashion industries have gradually shifted focus to high value-added, high sensibility, and multi-functional products based on new human-friendliness and sustainable growth technologies. Textile design CAD systems have been developed in conjunction with computer hardware and software sector advances. This study compares the patterns or images of actual woven fabrics and virtual fabrics prepared with a textile design CAD system. In this study, several weave structures (such as fancy yarn weave and patterns) were prepared with a shuttle loom. The woven textile images were taken using a CCD camera. The same weave structure data and yarn data were fed into a textile design CAD system in order to simulate fabric images as similarly as possible. Similarity Index analysis methods allowed for an analysis of the index between the actual fabric specimen and the simulated image of the corresponding fabric. The results showed that repeated small pattern weaves provide superior similarity index values than those of a fancy yarn weave that indicate some irregularities due to fancy yarn attributes. A Complex Wavelet Structural Similarity(CW-SSIM) index resulted in a better index than other methods such as Multi-Scale(MS) SSIM, and Feature Similarity(FS) SSIM, across fabric specimen images. A correlation analysis of the similarity index based on an image analysis and a similarity evaluation by panel members was also implemented.

This study aims to investigate the characteristics of Chinese consumers, who are growing up as the global biggest consumption market, according to G sensibility types, and to provide the data base for China market by analyzing the consuming pattern per sensibility and the preferred color. For the investigation, the survey on G sensibility and consuming pattern was conducted for consumers in four cities of China. As a result of classification of G sensibility types, it was found that Chinese consumers tended to behave in accordance with their values and identities and the most general type in them was G1 pursuing the reasonable and logical consumption, unlike Korean consumers who tended to be shown as G3 for the most general type according to the preceding study. As to characteristic of consumption, Chinese consumers preferred to purchase clothes from the department store, and in case of G2 type, the characteristics was corresponded with Actionist's character which shows the wide range of behavior and high-consumption, by preferring the road-shop next to the department store. Chinese consumers tended to purchase the clothes on the basis of their preferred colors, and especially it was shown that achromatic color was very commonly preferred. Also the black color was on the highest preference, and white, dark gray and light gray were followed. Meanwhile, in chromatic color, it was found that brown, orange, red and blue were preferred in order, and in case of G4, it was found that they preferred more various colors compared to the other types. This result could be used as the data base for the marketing strategy of fashion design industry and the related companies, as well as the new communication method for the consumers.

The objectives of this study were to find the relationship between the olfactory sense such as perfume and sense of sight and how it affects the sensibility based on the fact that ,senses are compound feeling from detective parts of human body. First, to build the emotional rate stale we selected the 19 pairs of adjective from the previous studies that overlaps smell, color, and clothes and added one pairs of related clause. Then each pair was divided into 7 level of emotional stage. In the experiment by the selected 15 man and woman from the visual design major student of Hong-ick Univ each student was given floral, jasmin, lavender, papaya and asked them to pick one color from I.R.I Hue & Tone chart for each smell. Then, analyzed the emotional rating of selected color for given smell. The emotional structure of smell and color consists five parts; 'Esthetics', 'Romance', 'Character', 'Intensity', 'Nature', There were significant differences in frequencies of selected colors for each given smell and gender difference also affected the color selected. Average value of emotional rating scale of smell and color was ,similar to the results from previous studies on relationship between smell and emotion.

최근 직물전극을 의복에 적용하여 의복을 착용한 상태에서 심전도, 심박과 같은 생체신호를 측정하는 방법이 다양하게 연구되고 있다. 그러나 대부분 직물전극의 경우, 높은 임피던스와 피부-전극 간의 불안정한 접촉으로 인해 생체신호를 측정하는 것은 매우어렵다는 문제점들이 지적되어 왔다. 이 논문에서는 피부-전극 간의 접촉을 향상시키기 위한 전극의 구조를 고안하여 의복에 적용함으로써, 착용자의 피부와 직물전극간의 접촉을 안정화 시킨 후, ECG(Electrocardiogram)를 측정하였다. 본 연구의 실험에 사용한 전극의 특성 분석 방법으로는 전극의 임피던스와 그에 따른 ECG 를 측정하여 SNR 분석을 실시하였다. 직물전극의 두 가지 구조와 직물전극과 트랜스미터 연결 스냅간 접촉 방식에 따른 ECG 측정을 비교한 결과, 전극 구조와 전도성 paste 사용 여부는 모두 ECG 측정에 영향을 미쳤다.
