일련의 dimethylformamide (DMF) 기반 폴리우레탄은 메틸렌 디 페닐 디 이소시아네이트(MDI) 1,4-부탄 디올 및 바이오 폴리올(1,3-프로판 디올: B-POL)에 기초한 폴리 트리 메틸렌 에테르 글리콜/폴리 에스터 폴리올(1,4-부탄디올: H-PET)으로 부터 합성하였다. 본 연구에서는 바이오 폴리올(B-POL)/폴리에스터 폴리올(H-PET)의 조성이 폴리우레탄의 물성에 미치는 영향을 조사하였다. B-POL/H-PET 혼합물의 B-POL 함량이 증가할수록 폴리우레탄의 소프트 세그먼트의 유리전이온도(Tgs)와 인장 강도는 감소하는 반면, 파괴 신도 및 인열 강도는 증가하였다. 한편 합성된 DMF 기반 폴리우레탄을 이용하여 습식공정으로 인조피혁을 제조하였다. 인조피혁에 형성된 다공성 셀의 평균 크기 및 밀도(단위부피당 셀의 수)에 미치는 B-POL/H-PET 조성의 영향의 차이는 거의 없는 것을 알 수 있었다. 이러한 결과들로부터 바이오 폴리올 기반 폴리우레탄을 습식공정으로 제조되는 인조피혁용으로 사용하는데 별 문제가 없음을 알 수 있었다.

This survey reports on the extensive examination of the qualify of 14 jogging and tennis shoes separately, availavable in the domestic market, Both jogging and tennis shoes were catagorised in two groups, namely the general goods(less expensive ones) and the exclusive goods(expensive models). The detailed classification are shown below; The domestic products meet the general purpose just as that of the foreign products. Due to the adhesion technology, the domestic tennis shoes consist of rubber sole with natural leather upper;In fact, the desirable combination, as foreign products, must be polyurethane/natural leather. The expensive models were heavier than the less expensive ones. The greater weight difference of right and left shoes are shown in the expensive models than that of the less expensive ones. The moisture absorption ratio of the expensive model is far superior in comparison with the less expensive model. The reason is identified by the material supplyed to produce the expensive model consisted of the natural leather and proper parts. The abrasion resistance of the expensive models were excellent that of the less expensive ones, because the rubber soles were showed the properties better than polyurethane sole which was used in the less expensive model.

The role of fashion image in modern society is being diversified from product planning to consumer satisfaction. In this research, after surveying female college students, the diversified modern fashion image was patterned. On the analogy of the relationship between these patterned image and design factors, the following conclusion was obtained. 1. The most popular styles are jacket and pants suits, three-piece outfits, tight mini-skirts and X-silhouette. Little decoration is used in general. simplicity is shown as trend by utility fabrics in single color-black, brown, beige and blue-with no pattern. Various materials such as wool, cotton, wool or cotton blended with other materials, silk, satin, knit, lace, vinyl and leather are used. 2. Fashion image is divided into four factors; factors that show fad, dignity, activity and simplicity. 3. Factors that show fad; style of tops, material of bottoms and length of bottoms reflect fad. blousons, three-piece outfits, pants rather than skirts, X-silhouette and mini-skirts are prevailing. Vinyl, leather, knit, lace and satin are the materials well used. 4. Factors that show dignity; Style and material of tops, the way of top and bottom pieces are matched and length of bottom or pieces reveal the characteristics. Jackets, blouses, half-coats and one-piece outfits rather than two-pieces are popular. Tight skirts in natural or midi length or pleated skirts are common. Wool, wool blended with other materials, leather and X-silhouette are design factors that reveal dignity well. 5. Design factors that show active image; Straight pants, three-piece outfits, T-shirts, shirt -blouses, vests, and blausons are popular. Knit and lace are used for tops, leather and vinyl are used for bottom pieces and cotton is widely used. Y- or H-silhouette are used to show active image.

At a time when the demand for environmentally friendly products is soaring, the fashion industry is following suit. The industry is showing particular interest in natural-dyed products. Against this backdrop, this study conducted a literature review on the history of natural dyeing for textiles and on the types of natural dyes. In addition, this study identified recent trends in the fashion industry and applied the findings from the literature review to those trends. Through this process, possibilities for new designs were suggested. This study proposed designs for various items-t shirts, one-piece dresses, blouses, skirts, and knitwear-by using threads and textiles dyed from mugwort, Polygonum indigo, safflowers, Lithospermum erythrorhizon, and Sophora japonica flowers. This study is also meaningful in that it broadens the boundaries of design for natural-dyed fashion products. To that end, various designs were attempted by combining natural-dyed textiles or knits with leather, denim, and fur.

Natural colorant extracts were obtained by extraction from tumeric root, gardenia seeds, mugwort and green tea using water, methanol, ethanol and acetone as extractants at room temperature for 3 hours under shaking condition(180rpm) with liquor ratio(solid:solvent; 1:100). The main pigment components of tumeric root, gardenia seeds, mugwort and green tea are known to be curcumin, crocin, chlorophyll b and epigallocatechin gallate, respectively. The effects of the kind of extractant and pH on the color characteristics of natural colorant extracts were investigated. The solubility parameters of pigment components were determined to find adequate extractant. The solubility parameters of curcumin, crocin, chlorophyll b and epigallocatechin gallate were found to be 27.85, 29.40, 19.48 and $37.97(J/cm^3)^{1/2}$. As expected, solvents that have a solubility parameter similar to that of pigment component were generally found to be effective to obtain pigment extracts having high visible absorbance(A). The extract(pigment/solvent) with high visible absorbance was generally found to have low $L^*$(lightness) and high Chroma($C^*$, purity).

The purpose of this paper is to examine the street fashion, which is influenced by the youth culture in 1960s. Youth culture is the youth subculture which appeared multiform in the 1960s. It tried to create a new culture by subverting the ruling class culture with their combative life style and peculiar appearance which are distinguished from mother culture. Youth cultures as youth subculture are symbolically expressed in their style which had strong characteristics of sub-fashion and anti-fashion, and which are different from mother fashion in shape. Therefore youth subculture fashion had an effect on street fashion in the 60s. The influence that the youth culture fashion had had on the street fashion is summarized as follows: Beats fashion was intelligency look on black dress, black polo-neck shirts, black trousers, black glasses and heavy black eyeliner. Mods fashion was neat style on Edwardian suit with narrow trousers, pointer-toeshoes and smooth croped hair. Folkis fashion was ethnic look, middle east asian look, peasant look, Indian style, south america look, gypsy style, natural materials, natural dying, tie-dye, beads and hand made ornaments. Rockers fashion was violence appearance categorized 'blue collar' on black leather jacket decorated with metal studs and hand-painted insignia, blue jeans and boots for motor bike. Swinging London & the Psychedelics fashion was blend mods look with pschedelic color and motive pattern. Hippie fashion was intermix pschedelic and natural or ethnic style. It was appear to be a meaningless, unpredictable assortment of diverse items and style. Faded and tattered jeans, army jackets, vintage hat, beads, embroidered headband, white sheets, diverse theatrical costumes, sandals or bare feet, granny dress, peasant blouse, blanket cape, tie-dye T-shirts and long hair. Greasers fashion was adorned black leather jacket with chains, fringing, badges, insignia and sleeves had been crudely ripped off. They came to be known wore jeans so soaked with oil. Skinheads fashion was aggressive working class identity with donkey jacket, jeans rolled up, collarless union shirts, heavy boots, braces and hair cropped short.

This study looked into the trend of expression of animal motifs that appears in modern fashion, and the values embedded in them. As to the research method, empirical analysis was performed on the works presented at the four global collections of Paris, Milan, New York and London from 2001S/S to 2010F/W, as well as a literature review. As a result, animal motifs applied in modern fashion appeared in material groups, such as leather or feather. The first group shows a realistic material feel, with artificial leather or fur, expressed in a transformed complex animal motif, with process skill or various methods of expression. The second group is the case of a single motif or reality, mode, and ion pattern. Printing is a generic expression, but patchwork, collage or bead ornament are also used, and expressed in the various forms of pattern: pattern in a single animal, pattern in different animals, and pattern combining both animal and other shape. The third group is a small decorative ornament, including headset or accessory and makeup, which is transformed in an animal-characterized motif into part of clothing components for expression, or to set the real animal to the stage for a performance. The embedded values were also categorized as natural beauty, sensual female beauty, pleasure, and ornamentation, which could be an endless spiritual source, and a breakthrough that enables us to show a creative and new aesthetic for the modern fashion field.
