PET fabric is used as a regular clothing in the middle-east region which is called Chador as a women's clothing and Thobe as a men's clothing. Then there is a big difference of export price according to the minute hand characteristics of the PET fabrics, of which characteristics are due to the fibre and manufacturing process characteristics. This research surveys the optimum manufacturing conditions related to the fibre and fabric for the Thobe clothing which were developed in this study through comparison with high price Teijin Thobe manufactured in Japan. In this research, four kinds of Teijin fabrics made in Japan were prepared as a target quality specimen, and five kinds of developed fabrics were produced as an experimental specimens. These specimens were made by changing yarn denier, twist, yarn setting conditions and fabric density, which are also changed by twist contraction, weaving and finishing shrinkages. As a result of this study, the sensitive characteristics of Teijin Thobe fabrics can be analysed from fibre and fabric, and then the manufacturing design technology was constructed under the base of low twist texturing and 3 dimensional fabric design simulation technologies.

This study has been performed to investigate into some effects of temperature, gas mixing ratio and time on the optical microstructure, hardness and wear characteristics of medium carbon alloy steel treated by plasma nitriding. The results obtained from the experiment are summarized as follows: (1) Optical micrographs of AISI 4140 steel plasma-nitrided by the double stage technique have revealed that the nitrided layer is composed of the compound layer and the diffusion layer. The variation in temperature at the first stage gives effects, on the formation of compound layer and the growth rate is shown to be relatively fast at $460^{\circ}C$. (2) The thickness of compound layer has been found to increase with increasing nitrogen percentage in the gas mixture and the holding time. It is therefore recommended that a shorter holding time and a lower nitrogen percentage are more effective to produce a tougher compound layer and a diffusion layer only. (3) X-ray diffraction analysis for AISI 4140 steel has shown that the compound layer consist of ${\gamma}^{\prime}-Fe_4N$ and ${\alpha}-Fe$ and that tough compound layer diffustion layer only can be obtained by the double stage plasmanitriding process. (4) There is also a tendency that the total hardened layer depth increases with increasing temperature, time and nitrogen percentage in the first stage during the double stage plasma nitriding. (5) The wear resistance of plasma nitrided specimens has been found thobe considerably increased compared to the untreated specimens and the amount of increment has appeared to increase further with increasing nitriding temperature, holding time and notrogen percentage of gas mixture in the first stage treatment.

The purpose of this study is to examine the recent various developments of men's fashion by analyzing how exotic tastes were presented in men's modern fashion from 2001 to 2010. For this purpose, a researcher reviewed relevant studies to identify the styles of exotic tastes that were reflected in men's modern fashion specifically in Chinese, Japanese, Indian, East Asian, American, North American and South American styles. Findings of this study is summarized as follows. Main examples of men's modern fashion were found in Chinese-style apparel such as the magwae, queue, coolie hat and the Mao jacket. The Kimono and the samurai robe, both of which best represent Japanese apparel and the Japanese traditional patterns also had an influence on men's modern fashion Indian style clothing such as dhoti, veshti and lungi which cover the lower body, vajani as loose trousers, kurta of full-over tunic form and turban also had an effect as well. The men's modern fashion is also impacted by Middle Asian styles that includes the thobe, sirwaal, futah, which is sort of a skirt that is long enough to cover the calf and whose front parts overlap each other, turbans and the hempen hood which is fixed with the agal. Exotic elements such as animal skins, body painting, tattoos and head dresses found in African styles can also be found in men's modern fashion. Parts of North American style influence come from the applications of Indians' costume and head dress. The surveyed men's modern fashion of the South America style was represented by the applications of natives' costume and Andean tunic, loincloth and shawl. In all of the exotic styles found in men's modern fashion, historicity, eclecticism, aestheticism and nature-orientation are implied. They are the source of inspirations that promote changes and diversity in men's modern fashion.
