The major advantages to use CAD System are that it reduce time and effort to manufacture products, and also can demonstrate the condition of the final product prior to the actual manufacturing process of the selected design using the simulation programs in CAD system. Specially in weave design, for use as Computer-Aided Weaving system, the complicated Dobby weave can figured out easily through calculating the complex weave plans of multi shafts. As to one of dobby weave structures, Supplementary warp is the warp threads which are in addition to the regular warps of the woven fabrics, and used for decorating the band or expressing some patterns. The purpose of this study is to research the weave design of Supplementary warp using Computer-Aided Weaving system, which is dobby weave design program of Weave Point. For performing this design study, it was researched the classified woven fabrics depending upon weaving processing, Computer-Aided Weaving system, and the characteristic of Supplementary warp fabrics. On the basis of the theoretical research, Supplementary warp was worked for the 24-shafts AVL computer dobby loom that applied to the various patterned images.

Fabrics shrinkage are affected by weaving conditions and are very difficult to be estimated when the amount of fiber consumption and production are calculated. Therefore, we need to standardize fabric shrinkage according to various weaving conditions. To develop the new textile products, we collected and analysed data of fabric shrinkage with the weaving conditions including twisting and covering process and denier of yarns used.

The article deals with issues related to the tradition of carpet production on the territory of Kazakhstan where, for the most part, tribes engaged in nomadic livestock raising lived. Analyzing the technological component of this traditional craft, the author focuses on the main factor that influenced carpet weaving along with arts and crafts-the nomadic method of production of the Kazakhs. The study of the ideological component that accompanies the process of making various types of carpets allows us to conclude that it has a sacred meaning and subordination to myth, rite, and ritual. At the mythmaking level, the process of making carpets, like any other activity among nomads, personified the process of creating the world, the marriage of Kok-Tengri (Heaven) and Zher-Su (Earth), and the creation of the Cosmos from Chaos. The process of carpet weaving, as well as the process of making felt, symbolized the act of creation, the marriage of Heaven and Earth, and male and female principles. The study of various types of ornaments that Kazakhs and their ancestors used to decorate carpets allows us to conclude that the ornament applied to carpet products was the bearer of the most valuable information about the mythological worldview of the people. Carpets in their structure reproduced the structure of the Universe, which has a binary, ternary, and quaternary system. The ornament has turned into a kind of coded text, reflecting ideas about the cosmogonic structure of the Universe and an awareness of the harmony of the world. The location of Kazakhstan on the northern routes of the Sogdian Road (Great Silk Road) allowed the spread of various ideas, due to which carpet weaving was influenced by other peoples in technical and stylistic design.

The process of weaving fabrics with high levels of tension and abrasion can cause damage to the yarn threads. To protect threadlines during the process, a protective polymer is coated on the surface of the yarns prior to weaving. This application process is known as slashing. The current slashing system is incompatible with today's demand activated manufacturing strategies. Methods of improving the uniformity of polymer coating application were studied, and several applicators were designed and evaluated. Prewetting of the threadlines before coating application was shown to greatly improve coating uniformity. The objective of the research is to design a single-end slashing process that is environmentally friendly and will improve productivity and flexibility.

This paper is focused on the traditional sash weaving handicraft of‘She’ethnic group, which is located in Fujian, Zhejiang, Jiangxi, Guangdong province of China. This research is main-ly based on the field work, analyzed and inter-preted the traditional sash in systematic and reasoned way. The summary of this study are as follows : 1. On its technological aspect, weaving structure of the traditional sash is made of warp rod backed weaving. The used tool is primitive one but the weaving process includes scientific method. 2. From the social-cultural point of view, the sash ha been the symbol of love towards her lover. Every woman of this group had taken training for this sash weaving from a child. 3. On its ethnological aspect, it has been long history and has interchanged with other ethnic group like Miao, Han and also Okinawa country of Japan. The pattern inside this sash are almost looks like characters, but they are not Chinese characters whereas are the inde-pendent code of‘She’ group and have been inherent from ancestors and which will be tran-smitted to their posterity. These independent code of‘She’group are the traditional message to their later generation implicating their natural circumstances, human relationship, ethnic myth, spirit etc. 4. I recognize that the pattern inside the sash is defined as the communicative code and in comparison to language, it is more repetition and less apparent as close code. Nowadays China has been developed es-pecially in the economical fields rapidly. Under the circumstances traditional weaving culture of ethnic groups has been facing a crisis of disappearance, which will be a great loss for the country as well as the human beings. For this reason, I emphasize that it is very immediate to make co-researches into the material culture of Chinese ethnic groups.

Textile and clothing in Ancient Egypt have carried long history and tradition. Especially, Egyptian textile culture, created mostly by the Copt, has the originality of weaving technology and the artistic beauty of the weaving motifs, making the textiles comparable to modern textiles. The purpose of this study is to research on the characteristics of Coptic textile designs of ancient Egypt and the tunic, a basic garment made of Coptic textiles, and offer materials for the development of the textiles and designs with artistic values which can be shared in the modern era, not just for the research of the relics of the past. Therefore, this study will follow the historical background of Coptic textiles and the process of the development, and look into the distinct features under the categories of material, colors and motifs. In addition, the tunic and its weaving technology will be explained and this will help understand the originality of Coptic textiles. The scope of this study is limited to the period of the 3rd to 12th centuries when the Egyptian weaving technologies advanced dramatically and many of the ancient Egyptian textiles discovered from the grave goods dates back, the research methode of the tunic as well as books published at home and abroad, research paper and photograph works. The textiles had developed along the Egyptian history which was influenced by different cultures such as Greek, Roman, pagan, Christian, and later, Islamic. For the textiles, they used a variety of pictorial motifs including Greek goddesses, pastoral scenes related to the Nile River and animals, human figures, geometrical figures and Christian icons. They are symbolic, natural, and mythological characters, and this explains that the world views and religions of the weavers influenced the development of specific motifs. Coptic textiles was used to make a tunic, a simple straight-sided gown without sleeves worn by men and women and was woven in a combination of linen plain weave and woolen tapestry weave for a tunic. Not only the excellence of the weaving technologies and the beauty of the colors used in the textiles, but also the diversity of the textures through weaving, embroidery, and knotting are detected in Coptic textiles.

It was attempted to improve seam-tracking performance by applying a new arc-sensing algorithm for FCAW(flux-cored arc welding) process in fillet joints. For this study the authors have introduced three different weight factors: $\circled1$ arc currents at the weaving end are more weighted, $\circled2$ arc currents are evenly weighted along the weaving, and $\circled3$ arc currents at the weaving center are more weighted. To evaluate the 3 factors the values of signal-to-noise(S/N) ratio has been measured. The values were obtained for various welding conditions with different gaps in horizontal and vertical fillet joints. The test results showed that the S/N ratio of the 1st case was highest which resulted in the best of seam tracking performance. In addition, the comparison between the seam tracking performance in horizontal fillet joints and that in vertical ones has been done, and the result showed that tracking performance in vertical joints was relatively better than that in horizontal joints.

An upflow BAF(Biological Aerated Filter) equipped with an expanded clay media was applied to reuse weaving wastewater of water jet loom. The performance of lab-scale biofilter was investigated by the adjustment of EBCTs(Empty Bed Contact Time) and the packing ratio of media, which were changed 1.1 to 3.7hr and 38 to 63%, respectively. In most conditions except 1.1hr of EBCT, BOD, CODcr, SS and Turbidity of the effluent were 1~4mg/L, 7~16mg/L, 1~5mg/L and 5~14NTU, where their removal efficiencies were 76~95%, 82~93%, 63~94% and 59~81%, respectively. From the observation of SEM(Scanning Electron Microscope) photographs of porous clay media, it was revealed that this media provided good performance of retaining microbes effectively. In addition, $0.44~0.49kgVSS/kgBOD_{rem}$. of low sludge reduction was expected. The most efficient back washing cycle and procedure were once per 4 to 9 days and air including collapse-pulsing method, respectively. Therefore, this system can be of use as an weaving wastewater treatment for reuse.

In this study a computer-aided textile pattern design system is implemented and a control methodology of a dobby motion is studied. The described system allows the user to design various weave patterns through graphic editor and to simulate weaving by displaying the dummy weaving process on the monitor. In addition, if the yarn colors are specified it is also possible to analyze color weaves. Thus it can replace effectively a conventional. design tool, a design paper. The main features of the system are to design weave patterns, to show weaving effect, and to make lifting plan for the dobby motion control. In dobby motion control, the mechanical. control method conventionally used is not adequate for the loom which is linked with the computer-aided textile pattern design system, so an electromagnetic control method is proposed.
