High functional textile market has been growing rapidly as a result of the accumulation of high-density fabric manufacturing technology and post-processing technology and the recent development of various functional fiber materials related to chemical fiber. Introduction of high functional fabric has resulted in changes in daily clothing. It appears that the clothing market based on sensible materials is transforming rapidly to functional materials. Now, it is apparent that the world’s clothing market recognizes the high functional fiber as the buzz word. In the interior market, which has been boosted by the "5-days-per-week" system and the high interest in "well-being", the brand-differentiation strategy has helped accelerate the usage of functional materials by the general public. While the new material development iscontinuing, the development of high functional fabric has become the biggest issue for the domestic chemical fiber fabric industry, which is striving for the high value creation. Many types of fabrics have been introduced one by one from the simple function of absorbing and removing sweat to the multiple functions of anti-germ, smell removal. Moreover, nano-processing technology has made the boundary unclear between the fashion materials and the frontier industrial materials, and helped open up a new dimension of high functional textile era. Therefore, in order to enhance the international competitiveness of the textile industry and pursue human health and richness, it is essential to achieve functional complexity and material property improvement, and for this it will be a powerful method if the existing textile technology is merged with the functional complexing technology. This will not only contribute to the development of other industry, but also help improve the quality of life by satisfying people whose life style is becoming more complex and at higher standard, and support the improvement of industrial environment as it is developed towards environment protection, resource and energy conservation. In addition, we expect job creation for high tech talents as the development of new processing technology will require new technical people. It analyzes the quality of consumer group from the research which it sees, the consumer is purchased the function characteristic soft goods and it advances the investigation against the quality star frequency of the right and wrong and purchase group with against the effect where the advertisement contact goes mad to the direct purchase of the consumer it analyzes and it proposes an improvement point the fact that in objective.

In order to enhance Hong Kong non-Chinese speaking (NCS) students’ ability to learn practical writing and presenting ideas appropriately in Chinese, Dr. Mark Shum Shiu Kee’s research team received funding from the Hong Kong Education Bureau to develop Chinese practical writing teaching materials for NCS students in 2016/17. This paper describes how the researchers develop these teaching materials by adopting Functional Grammar Theory, and investigates the effectiveness of the teaching material package at equipping the NCS students’ with ability in using function words. This paper aims at exploring how effective the newly developed practical writing teaching material package at enhancing NCS students’ ability to use function words is. With reference to the Systemic Functional Linguistic (SFL) Theory, Chinese practical writing teaching material package suitable for NCS students was developed. The package reading materials were developed by looking into the communicative function, schematic structure and metalanguage of different genres. Besides, NCS students’ difficulty in using function words and expressions of different genres were also analyzed. By referring to “Genre Function” theory and “Reading to Learn” pedagogy, interactive exercises that combine reading and writing were designed. These suggested exercises guide students to learn in a process, from deconstruction of the sample texts to joint construction and individual construction. Apart from the above, frontline Chinese language teachers were invited to conduct tryout sessions to test the effectiveness of the teaching material package. The analysis of students’ writings in pre-tests and post-tests, together with the research data from teachers and students interviews, provide a comprehensive evaluation on the effectiveness of the practical writing teaching material package. Feasible suggestions for enhancing NCS students’ ability, particularly in using function words and constructing practical writing, are provided for teaching NCS students to construct practical writing.

Potential Backfill Materials for Deposition Tunnels in a High-Level Waste Repository

Jae Owan Lee,Yohan Cha,Jin-Seop Kim 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.2

Backfill is one of the main components of engineered barrier in a high-level waste repository. The material selection of the backfill determines the barrier performance of the backfill. Overseas, its related research has been carried out mainly in Sweden, Finland, Canada, and Japan. However, Korea has recently started backfill research, and it is urgent to select a potential material for establishing the concept of backfill material and conducting backfill research. This study reviews NEA report, potential materials for overseas backfill research, advantages and disadvantages of single and mixed backfill materials, cases of license applications in Finland and Sweden for the selection of potential materials for backfill in Korea’s high-level waste repository. The review results indicated that it is reasonable to carry out backfill research according to the following plan: Both single and mixed materials are considered as potential materials for backfill research; experiments and performance studies are conducted with these materials; and, based on the results, a potential material or candidate material for the backfill suitable for the HLW repository in Korea is determined. For this plan, the single material is tentatively selected, as in Sweden, as bentonite with a montmorillonite content of about 40-50%. Then, if the selection criteria for montmorillonite content are determined through experiments and performance studies, we determine the final potential backfill material. As for the mixed backfill material, the bentonite/crushed rock mixture seems to be more advantageous than the bentonite/sand mixture considering the disposing problem of crushed rock generated from tunnel excavation and economic feasibility through its recycling. It is thought that the bentonite used in the bentonite/crushed rock mixture should have a higher montmorillonite content than bentonite used as a single backfill material since the crushed rock acts as an inert material in the mixture. The results of this study can be used as basic data for selecting the backfill material to be applied to the high-level waste repository in Korea, and can be used as a guideline for selecting the potential material required for backfill experiments and performance studies to be carried out in the future.

박태영,전향란 한국니트디자인학회 2009 패션과 니트 Vol.7 No.1

Paper yarn is currently developed as multi-functional and eco-friendly textile materials. Conventionally, manufacturing system of paper yarn comprises three steps: the first step for forming paper sheet with bast fiber or abaca, the second step for slitting the sheet into a paper tape yarn and the third step for twisting tape yarn into paper yarn. Most of patents related functional paper sheet, slitting apparatus, paper yarn, and composited yarn are registered and applied around Korea and Japan. To produce a tenacious paper sheet, the longitudinal fiber orientation, elastic reinforcing agents, and bast fibers with aspect ratio(fiber length/fiber diameter), 150 or more are mostly preferred. Since the breakage of paper yarn happened frequently during knitting or weaving process, several methods such as adhesion of wax and oil, steam treatment, and wet crepe process could be supplied to the tape yarn. Also, to prevent the shrinkage and rupture of paper yarn and to increase color fastness to light, some methods for preparing a union fabric and composited yarn with other yarns, or modifying fabric structure may be applied. From the fact that paper yarn has excellent property in humidity control function, air permeability, absorbency, antibiotic, and deodorant efficiency, the paper yarn can be fairly used in specific end-uses as well as fashion materials or home textile materials.

In information recognition of functional outdoor clothing, 40s showed the highest recognition, while 20s showed the lowest recognition. Second, 40s and 50s preferred functional material to 20s and 30s. In particular, 40s and 50s preferred clothing items with water vapor permeability & water repellent material to 20s and 30s. All age groups preferred insulation material jumpers, water vapor permeability & water repellent material jumpers and stretch pants. Third, reasons for purchasing functional material clothing was: design for the age group 20s and 30s versus health and function for the age group 40s and 50s. It is necessary to develop functional clothing products based on exact consumer information and preferences.

Production of Al2O3/Ti/TiN functional materials by means of nitriding in ammonia salts of Al2O3/Ti composites

Elizabeth Refugio-García,José G. Miranda-Hernández,José A. Rodríguez-García,Enrique Rocha-Rangel 한양대학교 세라믹연구소 2011 Journal of Ceramic Processing Research Vol.12 No.3

The production of Al2O3/Ti/TiN functional materials through the nitriding in ammonia salts of previously Al2O3/Ti fabricated composites was achieved. The matrix for the preparation of the functional materials is to create an Al2O3-based composite that presents a fine and homogeneous dispersions of very fine metallic particles of Ti. After the nitriding, microstructural observations were carried out on the transverse zone of the materials’ surface showing the presence of a very thin film of about 20 μm of a constituent that was identified with the help of EDS as TiN. In addition, measurements of micro-hardness on the surface and in the core of the functional material were realized in order to determine the effect of nitride formation on the hardness.

Material Pixel-based Process Planning for Layered Manufacturing of Heterogeneous Objects

Kim, Hong Seok,Shin, Ki-Hoon Korean Society for Precision Engineering 2014 International Journal of Precision Engineering and Vol.15 No.11

Layered manufacturing (LM) is emerging as a feasible technology that enables the fabrication of three dimensional heterogeneous objects such as multi-materials or functionally graded materials (FGMs). In this paper, we present a new material pixel-based processing planning method that takes into account not only the geometry, but also material variation along the build direction. The continuous material distribution on each 2D slice is first approximated by a set of material pixels. Iso-material regions for tool path planning are then computed by applying marching square algorithm to these material pixels. Next, the layer thickness at the current z-height is adaptively determined by calculating both the geometry-dependent and the material-dependent layer thicknesses. Once the slicing is done by repeating the previous steps (calculation of material pixels, iso-material regions, and layer thickness) for each slice, extra contours serving as support structures are added to each slice to obtain a complete LM model. We first introduce the representation scheme for heterogeneous objects and the new process planning method is then described in detail. Examples are shown to illustrate the overall procedure.
