In the direct digital textile printing process, the pre-treatment process is an essential condition for products by forming a clear pattern by sticking and penetration of DTP dye without spreading on the fabric. Recently, pre-treatment agent is changing from high viscosity to low viscosity in order to reduce defects of fabric during pre-treatment process. In this study, pre-treatment agent of acrylic polymer with low viscosity(less than 50cps) was prepared according to the solid content of the polymer, pre-treated on the cotton fabric, and direct DTP printing was performed to compare the color and sharpness. As a result, it showed high color at a viscosity of 50cps or less. When the solid content of the polyacrylic acid having a high molecular weight(A1) was 2.5wt%, when the solid content of the polyacrylic acid having a low molecular weight(A2) was 1 - 1.5wt%, the color was the best. And when the solid content of A1 and A2 was 1.5wt%, the degree of spreading was small and A1 was superior to A2 at the sharpness.

Fabrics for Digital Textile Printing (DTP) are different from it of general textile printing. It is necessary to pre-treatment of chemical agents for desired quality. But this process does not correspond with simplification of DTP processing. In this research, we pre-treated of cotto is necessary to pre-treatment of chemical agents for desired quality. But this process does not correspond with simplification of DTP processing. In this research, we pre-treated of cotton fabric for DTP by atmosphere plasma treatment and we understood that pre-treatment of fabric by atmosphere plasma treatment was more simple DTP process.

This study was to develop a dress form that is highly representative of the body shapes of senior men in their 50s and 60s. And this research was compared the measurements and forms of three different dress forms available in the market, in order to analyze the body type and suitability and provide a standard for developing and utilizing the dress forms. After extracting the body shapes of the senior men's 3D shape, the body type that is curvature on the back prevalent among senior men, was chosen. The dress form was created as follows: 3D modeling and rendering, printing with a FDM-type 3D printer. The dress forms were 3D-scanned and the 3D data was analyzed - classification drop value, area deviation, compared horizontal section and vertical section. The results were as follows: This suggested that the area deviation amount at the chest and hip circumference levels was larger in the commercial products than in the dress form in this study, while that at the waist circumference level was larger in the dress form in this study. The vertical length of the lateral shoulder point-waist circumference was smaller, the side shape showed severe curvature on the back, and the waist circumference was larger in the senior men dress form than the commercial products. The dress form developed in this study reflected the body type of senior men and, therefore, were suitable for fitting when creating clothes for senior men.

To develop a piezoelectric inkjet printhead for high-resolution and high-speed printing, we studied the characteristics of an inkjet printhead by analyzing the major design parameters. An analytical model for the inkjet printhead was established, and numerical analysis of the coupled first-order differential equation for the defined state variables was performed using state equations. To design the dimension of the inkjet printhead with a driving frequency of 100 kHz, the characteristics of the flow rate and discharge pressure of the nozzle were analyzed with respect to design variables of the flow chamber, effective sound wave velocity, driving voltage, and voltage waveform. It was predicted that the change in the height of the flow chamber does not significantly affect the Helmholtz resonance frequency and discharge speed of the nozzle. From the analysis of change in flow chamber width, it is observed that as the width of the flow chamber increases, the ejection speed greatly increases and the Helmholtz resonance frequency decreases considerably, thereby substantially affecting the performance of the inkjet printhead.

Industrial innovation in Britain, during the eighteenth and nineteenth centuries, stimulated the introduction of the factory system and the migration of people from rural agricultural communities to urban industrial societies. The factory system brought elevated levels of economic growth to the purveyors of capitalism, but forced people to migrate into cities where working conditions in factories were, in general, harsh and brutal, and living conditions were cramped, overcrowded and unsanitary. Industrial developments, known collectively as the 'Industrial Revolution', were driven initially by the harnessing of water and steam power, and the widespread construction of rail, shipping and road networks. Parallel with these changes, came the development of purchasing 'middle class', consumers. Various technological ripples (or waves of innovative activity) continued (worldwide) up to the early-twenty-first century. Of recent note are innovations in digital technology, with associated developments, for example, in artificial intelligence, robotics, 3-D printing, materials technology, computing, energy storage, nano-technology, data storage, biotechnology, 'smart textiles' and the introduction of what has become known as 'e-commerce'. This paper identifies the more important early technological innovations, their influence on textile manufacture, distribution and consumption, and the changed role of the designer and craftsperson over the course of these technological ripples. The implications of non-ethical production, globalisation and so-called 'fast fashion' and non-sustainability of manufacture are examined, and the potential benefits and opportunities offered by new and developing forms of social media are considered. The message is that hand-crafted products are ethical, sustainable and durable.

It was intended to conduct basic research to reduce development lead time and cost consumed in DTP process technology development. For the simulation of HTPE fabric, virtual engineering software was used to generate fiber model, yarn model, fabric model, and finite element model of HTPE fiber. The purpose of this study is to analyze the correlation and error rate between the stiffness numerical analysis results according to the direct DTP process parameters using reactive dyes in the generated finite element model and the stiffness measurements of the actual sample ac- cording to ASTM D1388. And, after dyeing the HTPE plain fabric according to the direct DTP process parameters, we want to analyze the dyeability of the HTPE fabric fabrics according to the direct DTP process parameters through the color fastness analysis. When looking at the results of the analysis of the finite element model, a higher value was shown when the distance between the nozzle and the fabric was 3mm than when the distance was 10mm. When the distance between the nozzle and the fabric was 10mm and 7mm, the reactive dye did not penetrate sufficiently, resulting in poor clarity when viewed with the naked eye.

본 연구는 먼저 자연주의와 자연주의 복식이 무엇인가에 대하여 고찰하고 그 개념을 바탕으로 자연의 요소 중 그 화려함과 다양함을 보여 주는 나비를 선택하여 자연 소재인 데님과 접목시킴으로써 인간 체형에 자연의 형태를 입혀 자연과 친화될 수 있는 고부가가치의 현대 복식 디자인을 창출하는 것을 목적으로 하였다. 그리고 디자인 도출방법으로는 요즘 디자인 작업에서 많이 활용피고 있는 CAD 시스템 중 가장 대중화되어 있는 Adove illustrator 10, Photoshop 7.0, Prima Vision Textile Design System을 이용하여 디자인을 하였다. 본 논문의 연구결과는 다음과 같다. 자연주의의 개념은 인간의 본질에 관심을 가지고 과학에 근거를 둔 사실적인 묘사로 객관성을 가지며 이로 인해 자연 속에서 삶의 본질을 찾고자 하는 것이다. 자연주의 복식의 개념은 천연의 가공하지 않은 소재와 자연의 색이나 천연염료의 색을 사용하고 자연의 모티브인 식물$\cdot$동물 등 자연 형상을 모티브로 하며 편안하고 자연스러운 실루엣을 의미하는 복식인 것을 알 수 있었다 그리고 나비의 뚜렷한 시각적 강조를 드러내는 구조는 어느 곤충들보다 화려하여 우리의 관심을 끌어들이는 데에 사용될 수 있고 작가가 의도하는 방향으로 발전시킬 수 있는 가능성을 확인할 수 있었다. 마지막으로 캐드를 이용한 프린팅 디자인은 수작업으로 이루어지는 일반 프린팅 기법에 비해 더욱 풍부한 색의 프린트 디자인과 다양한 시도를 할 수 있어 프린트 디자인에 더욱 많은 기회와 경제성을 제공하는 것을 확인할 수 있었다.

최근 젊은 세대의 전통 복식 체험이나, 퓨전 한복의 일상복화 등의 추세에 따라 한복용 헤어 액세서리의 개발이 필요한 실정이다. 본 논문의 연구 목적은 왕실 여성의 머리 장식을 활용하여 한복과 어울리는 실용적이고 현대적인 헤어 액세서리 디자인을 개발하여 한복 문화를 활용한 패션 콘텐츠 개발의 영역을 확장시키고, 전통 문화의 다양한 경험에 대한 수요를 충족시키는 것이다. 연구 방법은 문헌연구를 통해서 전통 머리모양 및 영왕비의 전통 장신구들을 조사하였고, 실증연구로 실물을 제작하였다. 제작과정은 먼저 전통 머리모양을 응용하여 나일론 메쉬로 기본 형태를 만들었고, 그 위에 장엄하고 화려한 왕실 유물을 활용한 디지털 텍스타일 프린팅 원단을 접목하여 궁극적으로 전통 장신구를 착용한 듯한 트롱프뢰유 기법을 줄 수 있도록 디자인을 설계하였다. 결과적으로 총 6개의 헤어 액세서리 디자인이 완성되었으며, 헤어 밴드, 헤어 핀, 헤어 고무밴드의 구조로 제작하였다. 또한 착용자의 헤어 스타일에 관계 없이 간편하게 착용할 수 있도록 하였고 나일론 메쉬 소재의 특유의 빳빳하면서 유연한 재질을 이용하여 볼륨감 있는 머리 모양을 효과적으로 표현하였는데, 이는 마치 머리카락과도 같은 시각적인 착시 효과를 즐길 수 있다는 장점이 있다. 이러한 연구 결과를 통해 일상의 유희와 희소성 있는 가치를 추구하는 대중들에게도 독특한 미적, 문화적 경험을 제시할 수 있을 것으로 생각된다.
