This study covers the stages of testing whether the azo dye with chemical name (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc (II) chloride (DMT), known as Maxilon Red GRL in the dye industry, can be used as an anticorrosive feasible inhibitory agent, especially in industrial areas other than carpet, yarn and fibre dyeing. These test stages consist of the electrochemical measurement techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) for diverse concentrations and durations. The adsorption of the viewed DMT molecule on the mild steel surface obeyed the Langmuir isotherm. The zero charge potential (PZC) of mild steel was also found to assess the inhibition mechanism in containing DMT solution. The inhibition performance of DMT on the mild steel in a 1.0 M HCl solution was also investigated using methods such as metal microscope, atomic force microscope (AFM) and field emission scanning electron microscope (FE-SEM).

In this study, a kiwifruit-produced protease was used to improve the quality of the wool and silk fabrics. The wool and silk were treated with the actinidin from kiwifruit. Following this protease treatment, changes in the surface of a single yarn of the fabrics were observed via both an optical microscope and a scanning electron microscope (SEM). In order to determine the amount of dye uptake in the fabric, changes in the K/S value of the wool and silk were measured by spectrophotometric analysis. Also, we performed a tensile strength examination to determine variation in their mechanical properties. By increasing the protease treatment time to 48h, the dyeing properties of fabrics were enhanced, and the surfaces of the single yarns of the fabrics became smoother, because of the removal of soil and scale in them. However, no mechanical changes were detected in the fabrics. Thereby, we suggest that the kiwifruit-produced actinidin treatment can improve the quality of the fabrics.

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.

이전의 연구에서 기존의 ATY 장치에 ITY 노즐을 접목하여 개조한 사가공기로 제조한 탄성복합사를 자동차 시트용 트리코트 원단으로 편직하여 일광견뢰도가 우수한 염료를 선정하고 $125^{\circ}C$에서 염색하여야 견뢰도와 spandex의 물성을 저해하지 않음을 알 수 있었다. 폴리에스테르 탄성복합사의 염색성 평가에 이어 본 연구에서는 나일론 필라멘트 (70/24, Full-dull, 2ply사와 40D spandex 1ply사 복합)와 레이온사(75D, 1ply)를 투입하여 직물 원단(중량 216g/yd, 밀도 경사 78, 위사 52본/inch)을 제직한 후 2욕에서의 염색공정을 거칠 경우, 탄성복합사의 견뢰도와 물성에 미치는 영향을 조사하였다. 나일론, 레이온, 폴리우레탄의 3종 원단을 염색성 평가를 위하여 반응성염료로 먼저 레이온 부분을 염색한 후 산성염료로 나일론 부분을 염색하였으며, 이 때 spandex가 미치는 영향을 비교하기 위하여 spandex가 함유되지 않은 나일론, 레이온 복합 제직원단도 함께 염색한 후 견뢰도를 평가하였다. 또한, 레이온 부분은 CPB염색법과 제트염색기로 나누어 염색하여 염색기에 따른 인장강도와 인열강도를 평가하였다. 레이온 염색에는 셀룰로오스용 2관능기 반응성염료 3원색을 이용하여 khaki color로 combination염색하였으며, 나일론 부분에는 입자크기가 커서 견뢰도가 우수한 산성염료를 선정하여 combination염색한 후 냉수세하였다. 견뢰도를 비교한 결과, spandex가 포함된 탄성복합사 원단과 나일론과 레이온 만으로 제직된 원단 모두 세탁, 마찰, 물, 땀, 일광 견뢰도 모두가 4~5급으로 우수하여 spandex에 이염된 염료가 견뢰도에 미치는 영향은 없음을 확인하였다. 또한, 레이온 부분의 반응성염료 염색 시 CPB와 제트염색법의 두 가지 종류에 대한 인장강도와 인열강도 평가결과는 CPB 염색물이 제트염색물보다 약간 높게 나타났지만 3% 이내의 차이로 거의 차이가 없음을 나타내었다. 일반적으로 제트염색 시 원단은 로프상으로 이동하고, CPB염법은 확포상태 그대로 염색되기 때문에 제트염색 시 강도가 낮아지는 것으로 알려져 있으나, 본 연구에서는 탄성복합사를 경사, 위사 모두 사용함으로써 spandex가 신장하는 특성 때문에 강도의 저하가 없는 것으로 사료된다.

Patterns are something that comes out of necessity in human life, which is closely associated with it. Thus come the SFAA (Seoul Fashion Artists Association) collection which uses patterns varying in form, color, way of expression and material. For this research, I first categorized the patterns the SFAA designers used into: natural patterns, symmetric patterns, traditional patterns, stripe, plaid, dot and abstract patterns. As a result of the process. the designers most favored the natural patterns and symmetric patterns, and dot patterns were rarely used. The designer who most favored patterns in general was Sul Yun-hyoung, and the designer Kim Chul-ung rarely favored the surface effect. The seven kinds of patterns naturally differ according to the designer. as Park Hang-chi liked to use the plaid patterns along with yam dyeing material, whereas Jin Teok expressed stripe patterns using the yarn dyeing fabric. Natural patters were presented in a bizarre way with Lie Sang-bong. who took the motives appearing in Eastern ceramic and paintings into the clothes, using the print method. The symmetric patterns, which the SFAA designers most preferred. was used evenly among designers like Chang Kwang-hyo, Gee Choon-hee. Rubina, and Haneza. In contrast. Lie Sang-bong. who used abstract patterns that do not give out meaning of the actual form of the pattern. rarely used symmetric patterns. The dot patterns were most often used by Park Youn-soo. and traditional patterns were overwhelmingly chosen by Sul Yun-hyoung. Secondly. in expressing the colors, SFAA designers were much more likely to choose achromatic colors. not choosing to show off colors. This is especially apparent in works by Haneza and Lie Sang-bong. In the SFAA collections, numerous methods were used to create. For instance, Sul Yun-hyoung used the oriental embroidery method. and Rubina and Lie Sang-bong used many unique dying methods. In terms of materials, Sul Yun-hyoung preferred silk. due to her methods, and Lie Sang-bong was one of the designers that used a number of different materials such as vinyl. Jacques Mueclier of the Paris Clothes Association in France, who was invited to SFAA collection once, remarked. "While the choice of material and the actual sewing done were excellent, there lacked much difference among the designers, as most of them choose flowing silhouette In terms of composition," which is all too correct. In addition, there were cases in the collection where the inherent feelings of cultural artifacts was expressed without alteration. Summing up, the research aimed to analyze the surface expression methods, forms and color of SFAA designs. and I hope that it can open up ways for new projects in the future.he future.

Polytrimethylene terephthalate(PTT) offers several advantageous properties such as good tensile strength, uniformity, stiffness, toughness, UV stability, resilience, stain resistance, outstanding elastic recovery, and dyeability. The effects of annealing temperature on physical properties and the structure of PTT filaments and yarn were investigated by measuring wide-angle X-ray diffraction (WAXD), density, optical birefringence, dynamic visco elasticity, and tensile testing. The intensity of maximum tan ${\delta}$ decreased and the temperature of maximum tan ${\delta}$ shifted to a higher temperature as the annealing temperature of filaments increased; however, it shifted to a lower temperature when the annealing temperature exceeded $130^{\circ}C$. In addition, crystallinity, density and D-spacing of (010) crystal face increased as the annealing temperature increased. Optical birefringence and specific stress were almost constant up to $100^{\circ}C$ and then decreased above $130^{\circ}C$. The shrinkage of PTT filament is 0 in boiling water when annealed above $130^{\circ}C$; consequently, the use of annealed fiber above $130^{\circ}C$ can remove thermal instability when dyeing PTT fiber. In the case of yarns, the thermal stability and physical properties of yarns showed the best effect when the ply number is less than 5, twist number is less than 400tpm, and the annealing time is 20minutes.

It was proved the practical use of the unique traditional Korean paper through the previous researches. The purpose of this study was to suggest the adequate application which is making various applied patterns in the fashion products so as to contribute to textile, fashion, and Korean paper industry. Six kinds of vests with the same fashion material using the Korean traditional paper were manufactured in order to investigate the images of materials in case of wearing them on the actual human bodies. As the results of image assessment for the materials and the factor analysis, 'classical', 'natural', 'Korean traditional', 'rural' and 'luxury' images were presented as the representative image of the Korean traditional paper material. Making repeated patterns of stripes and zigzag by sewing-machine stitches showed the natural effect on Korean traditional paper. Well-matched harmony was shown between holes made by the needle in sewing and slits torn by the tension to the needle and the thread. Especially, transparency by irregular holes formed by artificial frictional washing could shown special formative arts harmoniously with semi-transparency of Korea traditional paper and touch of sewing yarn. After the unripe persimmon dyeing, holes made by the needle became more hard and tight. The changes were no longer shown by the artificial frictional washing and then fixed. As the result of applying the Korean traditional paper fashion materials with various patterns for the basic formed garments, it was shown that the common and simple garments were changed the garments with special formation which could be found on the art garments due to the creative touch and formative arts using the Korea traditional paper fashion material. A variety of formative application by means of the developed samples was suggested to enlarge the practicality. As the result of this study, it was discovered that the possibility and application of fashion goods through the developed samples made of Korean traditional paper.
