In this paper, we analyzed the latest research trends, challenges, and potential applications of next-generation solar cell materials in various industrial fields. In addition, future prospects and possibilities of Smart Textile Hybrid Energy Harvesting Devices that will supply electricity by combining with wearable IoT devices are presented. The hybrid textile energy harvesting device fused next-generation solar cells with tribo-piezoelectric devices will develop into new 'Convergence Integrated Smart Wear' by combining the material itself with wearable IoT devices in the era of the 4th industrial revolution. The next-generation nanotechnology and devices proposed in this paper will be applied to the field of smart textile with an energy harvesting function. And we hope it will be a paradigm shift that evolves into creative products which provide AI services such as medical & healthcare by convergence with the future smart wear industry.

Smart clothing products can experience a decrease in performance and reliability due to various mechanical, biological, and chemical stress factors that occur throughout their life cycle. These issues can hinder consumer acceptance of the products. This study aims to enhance the reliability of smart clothing and facilitate quality control by analyzing and identifying the current status of international standardization for smart clothing and electronic textiles (e-textiles). The focus of this analysis was on the durability test methods in the use environment. Furthermore, similar standards published by different standardization organizations for durability tests were compared in depth. The study showed that a total of 27 international standards have been developed or are currently under development. The current standardization efforts mainly aim to develop functionality and durability test methods for smart clothing and e-textile products. A detailed comparison was made between two international standards (IEC 63023-204-1:2023 and AATCC TM210:2019) specifically in relation to the washing durability test method and the electrical resistance measurement standards (BS EN 16812:2016 vs AATCC EP13-2021), before and after the environmental exposure tests. Based on this comparison, several suggestions have been made and discussed for the future revision of these international standards.

현 의류 섬유산업의 트렌드는 친환경, 무공해, 인체친화, 고감성, 고급스러움 등을 표현할 수 있는 제품으로의 전환이 이루어지고 있으며, 최근 부드럽고, 편안하고, 모던한 특징 및 내추럴한 느낌을 나타내는 천연섬유에 대한 요구가 더욱 늘어나고 있다. 양모 섬유는 천염섬유 중 많은 비중을 차지하고 있는 단백질 섬유로서, 이를 이용한 다양한 직물과 의류제품은 국내외적으로 유명 브랜드 바이어와 지속적으로 내수와 수출이 이루어지는 대표적 섬유이다. 그러나 양모 소재에 특유의 구조와 형태로 소재간 섬도차로 인해 고급섬유에의 복합시 물리적, 감성적 이질감으로 상품화가 제한되고 있으며, 소비자 및 바이어들은 기존 보다 더욱 부드러운 고급감의 양모소재를 선호하고 있다. 이에 천염섬유 중에서도 세섬도 생산의 한계가 있는 양모섬유에 대해 양모섬유의 끝단을 마이크로 분활화 및 세섬화를 가능하게 함으로서 새로운 고감성 및 고급감을 부여할 수 있을 것이며, 본 연구에서는 산 및 초음파 등의 물리화학적 분할 기술을 적용하여 부분적 피브릴화 세섬화된 양모소재에 대한 염가공 특성을 기존 양모소재와 비교 함으로서 개질 양모소재의 제품화 실용성 여부를 검토하였다.

This study is the 2nd report following "A Study on the Characteristics of Material in the Korean Up-cycling Fashion Brands (Part I)" that handled the development of upcycling props using the characteristics of upcycling material. The 2nd report analyzed product types and materials focusing on 21 foreign upcycling fashion brands. It analyzed the characteristics of upcycling fashion materials using the case analysis of coffee bean bag and waste denim based on external characteristics and internal characteristics. We then classified the external characteristics into environment/economic feasibility and availability/mixture and the internal characteristics into historicality/story and originality/scarcity. Five bags were designed and produced for the actual commercialization of fashion products based on such characteristics of materials, with the use of coffee bean bags and waste denim as upcycling materials. This study is differentiated from existing research by its suggestions for the utilization of fashion product upcycling coffee bean bags and waste denim. Also, upcycling fashion products could be competitive products in eco-friendliness and originality that can be a driving force for the sustainable development of fashion industry through the differentiation of existing fashion products.

This study analyzes the current educational curricula in the field of Clothing and Textiles in order to develop appropriate educational methods and courses. We reviewed the curricula offered by 58 Clothing and Textiles Departments at four-year universities in Korea. We analyzed the educational content of each curriculum by dividing all of the courses offered into eight categories. The analysis was based on the information posted on the universities' Internet websites, and the analysis was performed by using descriptive statistics. The results of this study are as follows: First, the educational courses of the Clothing and Textiles Departments are composed of, 36.2% design, 20.4% production, and 14.5% textile categories. In comparison with the results of a similar study conducted in 1999, emphases on the design, distribution, and marketing categories have increased, while the emphases on the production, apparel material, basic knowledge, and consumption science categories have decreased. Second, in the case of the apparel material category, basic knowledge of materials constituted 18.5%, the largest part of the category. The average number of units offered in the area of apparel materials by the 58 Departments was 17 units per year. The curricula were found to vary by regions of the country. The universities located in the Chungcheong region offer more textile material courses, but the universities in the Capital region offer fewer textile material courses than other regions. Departments that are affiliated with universities that emphasize Art and Design have more courses on basic knowledge, dyeing and finishing, and fabric design than other universities.

본 연구는 청각적 감성을 만족시키는 의류소재의 개발을 위해, 직물 마찰음에 대한 인간의 감서을 생리반응측정과 심리적·주관적 평가를 통해 파악하고, 직물 마찰음이 갖는 음향특성과의 관련성을 고찰하였다. 이를 위해 직물 마찰음의 음향특성을 분석하고, 직물 마찰음에 대한 감각·감성 표현어(부드러움, 시끄러움, 유쾌함, 날카로움, 맑음, 거침, 높음)를 이용하여 주관적 평가를 실시하였으며, 생리적 반응으로서의 뇌파 및 혈류량, 심박변화율, 피부전도수준 등을 측정하였다. 주관적 감각·감성은 대부분 직물 소리의 크기와 관련이 깊은 것으로 나타나, loudness(Z)와 총음압 LPT가 증가할수록 시끄럽고 거칠며 딱딱하고 불쾌하며 탁하다고 지각하였다. 생리적 반응과 관련하여서는, 부드럽고 조용하며 맑다고 지각할수록 slow alpha파가 증가하였고, 유쾌하고 매끄럽다고 평가할수록 혈류량은 증가하였다. 또한, 높다고 지각하는 소리에 대한 LF/HF는 증가하였다. 마찰음의 음향특성이 생리적 반응에 미치는 영향으로서, LPT가 혈류량의 감소에, Loudness(Z)가 피부전도수준의 증가에 각각 영향을 미치며, sharpness(Z)가 높고 ΔL이 작을수록 LF/HF는 증가하는 것으로 나타났다.

탄성체는 크게 열경화성 탄성체(thermosetting elastomer)와 열가소성 탄성체(thermoplastic elastomer)로 분류할 수 있다. 이러한 탄성체들 가운데 대표적인 소재로 반복하여 재사용이 가능하여 경제적인 소재이며 환경친화적인 소재인 열가소성 폴리우레탄에 대한 관심이 높아져 왔고 그에 따른 연구도 활발히 진행되어 왔다. 이러한 열가소성 폴리우레탄(TPU)은 가공의 용이성과 양호한 물리적 ㆍ화학적 성질 때문에 섬유용 소재에서 엔지니어링 플라스틱에 이르기까지 광범위한 산업용 소재로의 개발을 통하여 사용량이 지속적으로 증가를 보이고 있다.

The purposes of the present study were to investigate the impact of a apparel brand and an ingredient brand on evaluation(perceived quality, favorable attitude, purchase intention) of apparel products, and to examine the differences in evaluations toward apparel products allied with ingredient brands between groups divided by product knowledge and leisure involvement. The subjects were 235 men and women aged 20 to 40. Two-by-two factorial design were employed. A series of ANOVA were used to determine if significant differences existed in evaluations of apparel products. There was a significant interaction effect of an apparel brand and an ingredient brand on evaluations of apparel products. Empirical results showed that ingredient brands would improve the consumers' perceived quality, favorable attitude and purchase intention toward apparel products. In addition, the results indicated that the respondents that had high leisure involvement and high product knowledge were more likely to evaluate apparel products based on the ingredient brand of the products. However, the respondents that had low leisure involvement and product knowledge were more likely to evaluate apparel products based on the host brand of the products.

본 연구에서는 PET 직물의 물성개선과 품질의 향상을 위해 직물 제조 공정 중 제직준비공정인 1TY, P/W, 2-FOR-1공정에서 여러 가지 공정인자의 변화를 주어 염색·가공 공정을 거친 최종 11가지 직물의 역학적 특성치 및 각 공정별 시료의 물성을 측정하여 의류의 감성특성은 Handle, 의복성능 및 봉제성을 평가하여 직물 제조 공정특성이 의류 감성에 미치는 영향에 대해 분석하였다. 그 결과 1TY, P/W, 2-for-1공정에서 균일하고, 안정된 장력으로 제조한 직물은 신축성 및 drape성이 장력이 과다하게 주어진 직물보다 우수하고, 의류봉제시 신장성이 양호한 봉제 범위를 가져 의복 착용시 감성면에서 부드럽고 쾌적한 성능을 가진다. 그리고 공정에서 고장력, 고속의 spindle 회전은 사물성 및 직물의 물성변화를 야기시키고 교략강도의 불안정성으로 최종 직물에서 유연성과 탄력성 및 volume감이 떨어지는 의류촉감을 가지며 또 stiff한 의류 감성을 나타냄으로서 의류용 소재로는 부적당함을 확인하였다.
