Entering the period of Mass Customization, and with the help of the Digital Textile Printing technology, the purpose of this study is to propose two customer involved design process models, based on the Digital Textile Printing technology, and to compare their efficiencies and appropriateness with those of the existing design process model, which would lead us to discover the possibilities of Mass Customized design process. By the result obtained from the survey of 166 females in their twenties and thirties, the second Mass Customized design process model which gave most choices to prosumers was preferred the most, while the existing design process which gave no choice seemed to be preferred the least, and among the design elements of textile, color appeared to be the most significant influential factor in the preference of the clothing by the consumers. In summary, it appeared that every aspect of the society requires a shift in the process of the thought from Mass Production to Mass Customization at this point, and a guideline was made from the Mass Customized design process suggested in this study.

Blowing film was prepared using polyester elastomer with thermally expandable microcapsule to investigate the optimum blowing properties and the film making process. Physical properties including specific gravity, blowing efficiency, foaming shape, tensile strength and elongation of polyester film were tested by varying the process condition of temperature and revolution per minutes of the extruder. The lowest specific gravity of 0.709 can be achieved with excellent foaming cells at $210^{\circ}C$ and 50 RPM conditions. The highest tensile strength and elongation was shown at $210^{\circ}C$, 100 RPM and $230^{\circ}C$, 25 RPM conditions. However, most of the prepared polyester films showed over $1kg_f/mm^2$ of tensile strength which is reasonable value to use in film applications.

This study sought to develop clothing for a companion animal that can provide stable ECG measurements. A pattern for the smart clothing of a companion dog was manufactured using the replica method to select a location and method that best suited the stable measurement of ECG and improved the clothing's fitness. The smart clothing was developed as the following three types: strap type, top type, and combined top and vest type with a detachable wireless ECG monitor. The detection abilities of these were observed using the PQRST rate taken after ECG measurements while the three companion dogs were tested while resting and moving. The results revealed that apart from using an electrode, applying a gel pad is the most effective way to achieve stable ECG measurements, and the central chest region is more reliable than the left armpit for providing steady readings. The combined top and vest type showed the highest average ECG PQRST detection number, meaning that the ECG signal measurement was steady. These results may contribute to the measurement of ECG in smartwear for U-Healthcare to measure other biometric data of a companion dog.

Recently, the consciousness of energy crisis is rapidly growing and sustainable eco-friendly energy sources are becoming issue. Therefore the portable electronic device requires new energy sources for providing continuous power supply and the power energy harvesting system of the human body that enables the power-harvesting research requests anytime, anywhere. One of the sources for energy harvesting is heat energy, which is the difference in temperature of the body and the surrounding environment. We tried to analyze the temperature difference between the environmental temperature and the temperature inside clothing according to the structure of the closed portion. And we examined the temperature difference between the environmental temperature and the temperature inside clothing according to the material of the clothing. The analysis showed that we have been able to get different results at parts of the body in the temperature inside clothing according to the structure of clothing. In upper torso of the chest and back, the temperature inside clothing of 'closed structure' was higher than the temperature inside clothing of 'opened structure'. In the section of arm and leg, it was reduced the difference of temperature inside clothing between 'closed structure' and 'opened structure'. It was particularly noticeable in the section of leg. The results of analysis of the difference between the environmental temperature and the temperature inside clothing according to the material of the clothing, in both cases of the two materials, 'closed structure' was higher than the 'opened structure' in the difference value between the environmental temperature and the temperature inside clothing. There was a difference according to the material in the section of leg. In this study, we outlined the basic guidelines for developing heat energy harvesting clothing by exploring the structure and material of clothing suitable for the heat energy harvesting.

The purpose of this study is to examine the hand of spring/fall fabrics for 'Saenghwal Hanbok' on subjective hand, objective hand and the preference. In this study, 28 varieties of spring/fall fabrics such as cotton fabrics, synthetic fabrics, blended fabrics and a silk fabric for 'Saenghwal Hanbok' are used. To evaluate the subjective hand of fabrics, the holistic touch and preferences, 33 seven ranks' segmentic differential scale questions are developed with adjective pairs and are gathered by surveying experts on clothes. The mechanical properties, HV and THV of them are measured and calculated by KES-FB system. Through subjective hand, items could be classified into six hand expressions: 'bulky/extensibility', 'stiffness', 'feeling of weight', 'surface property', 'drapability' and 'moisture property'. Through mechanical properties, the results indicated that the character of cotton fabrics are slight flexible, tough, rough, uneven, a bit heavy, thick and low resilience on tensile and compression, and then those of synthetic fabrics, blended fabrics and a silk fabric are thin and light, smooth, flat and bulkless. In correlation on subjective evaluations and the preference for 'Saenghwal Hanbok', cotton fabrics mainly depend on 'surface property' and 'moisture property' and then synthetic fabrics, blended fabrics and a silk depend on 'bulky/extensibility' and 'surface property' In correlation on objective hand and the preference for 'Saenghwal Hanbok'. people aren't satisfied with low resilience. high stiffness and low drape.

아라미드는 일반적인 유기섬유와는 다른 우수한 역학적 성질을 바탕으로 보호의류 중에서 방탄방호 및 방검보호 의류에 사용되는 고부가 소재이다. 현재까지 ATY기계에서 사의 구조와 물성에 큰 영향을 미치는 Nozzle의 구조에 대한 연구결과는 많이 발표되어왔다. 그러나 최근 들어 소방방화방 검용 보호의류에 많이 사용되는 아라미드사에 ATY 공정 중에서 Nozzle의 직경이 ATY사의 물성에 어떤 영향을 미치는가에 대한 연구는 발표된 바가 없다. 따라서 본 연구에서는 Para-aramid/Nylon hybrid사를 이용하여 ATY로 제조할 경우, 표면에 생기는 loop로 인하여 타 소재와 접착시, 접착제 담지 성능이 향상되어 접착력이 상승되는 반면 아라미드 Hybrid사의 역학물성은 ATY가 가공되기 전의 물성보다 저하되는 약점을 가지고 있다. 따라서 본 연구에서는 ATY 제조공정에서 Nozzle의 직경을 달리할 때 Aramid/Nylon Hybrid ATY사의 물성변화를 분석함으로서 방화복과 방검용 보호의류에 적합한 아라미드 ATY사를 개발하고자 한다. 본 연구에서는 ATY 제조공정 중 다른 공정조건은 동일하게 하고 Nozzle의 직경을 0.6, 0.75, 1, 1.2mm로 변경하여 4가지 시료를 준비하고 물성분석을 위하여 제조된 시료의 강신도, 초기탄성률을 각각 측정하여 인장특성을 확인하였으며, 건열수축률과 습열수축률을 측정하여 시료의 열 수축률을 측정 분석하였다. 표면의 루프 발현 정도를 보기위하여 형태 불안정성을 측정 평가하였으며 영상현미경시스템을 사용하여 표면특성을 측정 평가하여 다음과 같은 결론을 얻었다. Nozzle의 직경이 증가함에 따라 절단강도는 30% 감소하였고 초기탄성률은 3배 가까이 감소하였다. 그리고 절단신도는 2배정도 증가하는 경향을 나타내었다. 또한 Nozzle의 직경이 증가함에 따라 ATY hybrid사의 건 습열수축률이 증가하다가 직경이 1.2mm일 때 감소하는 경향을 나타내었고 직경 변화에 따라 4~6%의 열 수축률의 분포를 보였다. Para-aramid/Nylon hybrid사의 형태불안정성은 0.3~0.5%를 분포를 나타내었고 Nozzle의 직경이 0.6, 1mm일 때 상대적으로 낮은 ATY의 불안정성이 확인되었다. Nozzle의 직경이 감소할수록 loop의 엉킴이 적으며 flat하였으며 직경이 1.2mm일 때 가장 조밀하고 표면에 loop가 많이 형성된 것을 확인하였다.

The COVID-19 pandemic increased people's time at home and caused an 80% increase in noise disputes between floors. The purpose of this study is to propose suitable materials for making indoor shoes (insoles) to minimize noise between floors. Subjects without back pain and leg-related disease (e.g. arthritis, etc.) from three different age groups (childhood, adolescence, and adulthood) were recruited for the study. Five polymer insole materials were considered: Chloroprene Rubber (CR foam), Ethylene Propylene Diene Monomer (EPDM foam), Natural Latex foam, Ethylene Vinyl Acetate (EVA foam), and Polyurethane (PU foam). From these materials, 20 combinations were prepared and randomly tested for noise and vibration. The results revealed a significant difference in noise and vibration levels based on the type of material used and the age of the subject. Nevertheless, all materials under consideration successfully reduced noise and vibration; in particular, type A-C greatly decreased. The CR foam material was especially effective at noise and vibration reduction (p<.01). This study suggests that adding insoles into socks that children wear at home could reduce noise vibration and disputes between floors.

This paper starts out with a review of the concepts of naturalism and natural clothes. Based on these concepts, the paper aims to create nature-friendly and high-value modem designs by grafting natural images from butterflies into human bodies. The images of butterflies are combined to show distinguished luxury and diversity with natural materials such as denim. As for the design technology, Adove Illustrator 10, Photoshop 7.0, and Prima Vision Textile Design System are used since they are very popular in the CAD system. The followings are the main findings of our research. Naturalism displays its objectivity based on its inherent interest in human nature and its factual description in scientific approaches with an intention to find a true meaning of human life in nature. Natural clothes can be defined as the clothes of natural silhouette which are made of pure materials in natural colors and dyes from natural motifs such as animals, plants or natural phenomena. We have realized that the visually distinguished looks of butterflies are indeed far more luxurious than those of any other insects and this visual distinction can be utilized to attract the attention from designers. Lastly, it turns out that the digital printing technique can create more variety in colors and design forms than the manual printing, thereby providing designers with more options and practicality.
