In this paper, micro dried bio-potential electrodes are demonstrated for sEMG (surface ElectroMyoGraphic) signal measurement using conductive epoxy on the textile fabric. Micro dried bio-potential electrodes on the textile fabric substrate have several advantages over the conventional wet/dry electrodes such as good feeling of wearing, possibility of extended-wearing due to the good ventilation. Also these electrodes on the textile fabric can easily apply to the curved skin surface. These electrodes are fabricated by the screen-printing process with the size of $1mm{\times}10mm$ and the resultant resistance of these electrodes have the average value of $0.4{\Omega}$. The conventional silver chloride electrode shows the average value of $0.3{\Omega}$. However, the electrode on the textile fabric are able to measure the sEMG signal without feeling of difference and this electrode shows the lower resistance of $1.03{\Omega}$ than conventional silver chloride electrode with $2.8{\Omega}$ in the condition of the very sharp curve surface (the radius of curvature is 40 mm).

India has had a rich and diverse textile tradition since the 3rd millennium BCE. The origin of Indian textiles can be traced back to the Harappan period. Owing to the hot and humid climate in most parts of India, cotton has remained India's favourite choice of fabric for normal use. Thus, India is supposed to be the first nation to have grown, woven, and patterned cotton fabrics. Moreover, India is one of the leading cotton-growing countries in the world. The earliest occurrence of cotton thread in India is roughly datable to 4000 BCE and of dyed fabrics to about 2500 BCE. Large numbers of needles and spindle-whorls found in Harappa and other early historic sites in India reveal the prosperous state of textile production and its trade in the early period. The textile producers used a wide range of skills to process raw materials and make regionally idiosyncratic dyes, weaves, prints, and embroideries. Additionally, the silk from wild indigenous forms of silkworms was known in the Indian sub-continent roughly contemporary with the earliest clear archaeological evidence for silk in China. The analysis of thread fragments found inside a copper bangle and ornament from Harappa and steatite beads from Chanhu-daro, have yielded silk fibers dating to 2500-2000 BCE. Apart from other products, cotton and silk textiles were important export materials from India right from the Harappan period. Actually, the sea-borne trade had played an important role in the economic growth and prosperity of the Harappan civilization. Several ancient seaports in the entire coastline of India played a vital role in the maritime trade during the Harappan period and cotton and silk textiles of Indian origin have been found in various countries. The contemporary writings and epigraphy have also attested to the vast maritime trade network of India and the export of textile materials. The paper discusses in detail the origin and development of cotton and silk textile production in India through the ages and its role in maritime trade networks.

This paper deals with the grey fabric deformation during relaxation. It investigates the effect of twist direction and twist liveliness on the 2/2 twill weave woven fabric distortion, during relaxation This experimental work shows that twist liveliness increases the natural tendency of the twill weave woven fabric to skew. In addition when the twist direction of the warp and weft is opposite to each other the bias curling occurs too.

This paper proposes a new color feature and a corresponding distance measure for content-based retrieval of design images such as trade marks, pattens, logos, textile images, and icons. Simulation results with textile images show that the proposed method outperforms the traditional color-based retrieval methods which was originally proposed fer content-based retrieval of natural images.

In this paper, in order to examine the torsional behaviour of twisted yarn closely, the torsional rigidity would be derived in terms of physical and mechanical characteristics of its constituent fibers and yarn structural parameters by energy-method. And the propriety of the theory will be discussed by comparing with experimental results. The torsional rigidity of yarn in both experimental and theoretical results decreases with surface helix angle increases. But the experimental values are more higher than those of the theoretical ones.

Inflatable panels made of modern and new textile materials can be inflated at high pressure to have a high mechanical strength. This paper is based on the finite element method as a general solution to determine the characteristics of deformed inflatable panels at high pressure in various end and loading conditions. Proposed method is based on the construction of weak form of formulation and application of Reduced Integration Element method (RIE) to solve the numerical problem of shear locking. The numerical results are validated as an outcome of comparison with other published results.

The purpose of this study is to investigate effects of natural incense on the preservation of paper- and textile-based remains and the kinds and applications of natural anti-insect incense by reviewing relevant literatures of the ancient times. There are few ancient literatures of incense published in Korea. The researcher deducted how incense was used in this nation through reviewing verses contained in ancient literatures and medical books. In contrast, the kinds and applications of anti-insect incense used in China, where incense culture prospered, were investigated here through reviewing technical books about incense published during the Song(宋) and Ming(明) periods, $\ll$Incense record(香譜)$\gg$, $\ll$Chen's Incense record(陳氏香譜)$\gg$ and $\ll$Incense record(香乘)$\gg$. There were several methods of keeping clothes better from insects. In relation, how to use anti-insect incense varied in accordance with main materials of clothes, paper, textile, leather and others. Cymbopogon dstans(芸香), Brassica rapu var and Incarvillea sinensis(角蒿) are anti-insect incense which were used for paper. Anti-insect incense for textiles is classified into single and mixed incenses depending on whether only one kind of incense was used or more than seven kinds of the substance. Acori rhizoma(菖蒲), Capsella bursa-pastoris(薺菜花), Lactuca sativa L., Erigeron canadensis(莽草), Stemona japonica(百部) and Moschus sifanicus(麝香) are single anti-insect incense which were used for textile. While, the latter was called. ‘Yi Xiang(衣香)’ is mixed anti-insect incense which was used for textile. Artemisia asiatica(艾葉) and Zanthoxylum schinifolium(花椒) are anti-insect incense which were used for leather. Angelica dahurica(芳香) and Bamboo are anti-insect incense which were used for others. There were three main methods of using incense to prevent insects, that is, diffusing incense's strong scent and ingredients, exposing to smokes from burnt incense and washing with incense-boiled water. Diffusing incenses had a strong scent and antibiotic ingredients, which were put between books or clothes or into a storage box without being processed. If necessary, however, they were processed into rough powders that were in turn used singly, or otherwise mixed for a stronger scent and better insect elimination. Exposing to smokes from burnt incense was done as follows. A clothes was put on 'Long(籠)' underneath which there was a boiling water. The clothes was humidified by the water and then exposed to smokes from burnt incense. 'Long(籠)' had been long used since it was manufactured in the QinHan(秦漢) period for the first time. A local literature, $\ll$Koryo TuGing(高麗圖經)$\gg$ shows that in the Koryo(高麗) period, BoShaLu(博山爐) were used as a means of exposing clothes to smokes to prevent moths, similarly to China. Washing clothes with incense-boiled water was more effective in removing lots of worms and germs from clothes, but leaving the scent and ingredients of the used incense and maintaining the effect of anti-insect.

Korean Paintings have been drawn on in the main two types of support material - paper and silk. In these things, silk designates picture silk, that of a specially weaved textile for painting since CHO-SUN dynasty, different such as hemp, ramie have been started to use for support material In addition to picture silk. However the structure of hemp and ramie are so close and progue, They are not proper to express the technique of pigments on the back of the paintings. On the other hand, picture silk is efficacious in pigments on the back of the painting with its interval between the strands and translucent textile. As the result, paintings on the silk has many - sided techniques as compared with painting on the papers therfore various devices in conservation have to be considered to deal with the techniques. In this report the focus is on classifying the method of removing the Lining paper according to the several types of expression technique of paintings on the silk.

Various paper ornaments appear in Gut, the rite of shaman in Jeju, and these are frequently called Gime, Gimekijeon or Gimejeonji. Gime are slips of white or colored paper, made to resemble the shape of god and used in the ritual shaman dances of Jeju. These Gime are hung around an altar, fastened to the end of a green bamboo pole, or held in the shaman's hands when they dance. The purpose of the study is to develop textile design based on the formative features of Gime, as a way of using Myth of shaman in Jeju. This study is used Gime made by 'Kim Yoon-Su' Simbang (shaman) who plays a role of Intangible Cultural Assets of The 71th 'Jeju Chilmeoridang Yeongdeunggut'. As a result, it was to develop the Komusaljang pattern, Seongjukkot pattern, Jijeon pattern, Jowoangki pattern and Cheoljjukdae pattern design of Jeju image using Gime that is one of the unique, indigenous pattern of Jeju.
