In this paper, we propose a new weaving trajectory algorithm for the arc welding of a articulated manipulator. The algorithm uses the theory of Bezier spline. We make a comparison between the conventional algorithms using Catmull-Rom curve and the new algorithms using Bezier spline. The proposed algorithm has been evaluated based on the MATLAB environment in order to illustrate its good performance. Through simulations, the proposed algorithm can result in high-speed and flexible weaving trajectory planning so that it's trajectory cannot penetrate into a base metal compared to the conventional algorithm using Catmull-Rom curve.

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.

The art of carpet weaving is the most habitual form of traditional art in Azerbaijan, it reflects a rich inner world and occupies a special place in the history of a national culture's development. The Azerbaijani carpet has always stood out for its plots, ornaments, compositions, and high quality and the Azerbaijani people, faithful to their spiritual values, have protected and developed it throughout the centuries. In this article, several Ganja-Gazakh-type carpets from the Azerbaijan National Carpet Museum collection and their artistic and technical characteristics are discussed. Specimens of material, sacred language, and ornamentation are considered. The deepest meaning is embodied in tamga in particular. Tamga is a unique phenomenon serving as an amulet, lineage sign, and self-identification of Turkic peoples. The Gazakh carpets of the Ganja-Gazakh type cover the Gazakh region of Azerbaijan, the Borchali region of Georgia, and the Goycha Lake region of Armenia. Karapapakh Azerbaijani Turks have inhabited these areas since ancient times. Tarakama (nomads) are often equated with the name Karapapakh (black hat).

This study attempts to address the development processing of yarn-dyeing jacquard design by using jacquard textile design professional CAD system to create high valued worth products. To carry out this purpose, two kinds of necktie samples were designed and each of them was different in three types of weaving method. The results are as follows; All over type is appropriate when the motive's size is small. And the work can be finished within short time and design can be illustrated by basic jacquard system. However, one point type can represent rather big and audacious motive but it needs lots of working hours and jacquard system. Though the motives are identical, showed many changes in cubicle representation according to weaving methods and the structure. To express simple and modest design, single fabric woven is suitable and in the need of colorful and technical design, expressing by double weft cloths and triple weft cloths rather than single fabric woven are better to give creativity and colorfulness. For the production of jacquard design, cad system using ability is important but the understanding and study of the whole process of weaving development should be made.

This study examined textiles used for the ancient costumes that are excavated from tombs of the Chosun dynasty, focusing especially on Po(overcoat). The result of the study is that silk occupies 79.8% of all the textiles used for Po, and cotton and linen follow. The weaving method of silk was primarily plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo dynasty, are considerably decreased in Chosun dynasty. Danlyeong(단령) and Cheollik(첩리) had been made of various textile fabrics like cotton, linen, silk and blended fabric before Imjinwaeran(임진왜란). After the war, they were simplified in gauze weaved silk or satin weaved silk, And also patterned fabric were widely used for them than other Po. Simple fabrics like cotton, linen and plain weaved silk had been used for Aekjureum(액주름) and Jiklyeong(직령) before Imjinwaeran. After the war, Jiklyeong was used as underwears of Danlyeong, so it was made of high quality patterned silk. Dopo(도포) and Changuiryu(창의류) were mainly excavated from tombs after the war, high quality plain weaved silk are used than gorgeous Patterned silk. For the Dopho(답호) and Bansuui(반수의), before the war, they were made with various textiles such as plain weaved silk, twill weaved silk, satin weaved silk, cotton, linen, and blended fabric. But after the war plain weave was mainly used. In Jangui(장의), since it was mostly for women, many kinds of women's patterned silk were used in than any other Po. There were only a few excavation of Simui(심의) and most of them were made of ramie and were hemmed in black satin without pattern.
