The study aims to analyze the mixed characteristics of knit fashion design as demonstrated in Sacai's collection, which promotes hybrid and mesh-up fusion and proposes various knit design ideas. Standards for categorizing mixed phenomena of Sacai's knit design were established through a review of literature and data analysis. The study's data collection period was from 2012 to 2021, and a total of 174 items were analyzed. The following are the results. First is the fusion of traditional knit and contemporary styles expressed through de-constructive design; traditional knit styles are combined with contemporary styles through color, material, and knitting structure mixtures, such as mixing Northern European Aran, Fair Isle, Nordic, and Ropy knit. Second, the Sakai knit design combines male and female styles by mixing materials and details. A deconstructed knit cardigan was matched with androcentric pin-striped shirts worn over layered shirring skirts embellished with chiffon and lace. Third, everyday street fashion style is blended with a formal, elegant fashion style. For example, the front view has a typical everyday appearance, whereas the back view contains florid and decorated details. The style is expressed as a 360-degrees appellation, with one thing in the front and another in the back. Sacai's distinctive expressional characteristics include a mixed and de-constructive style characterized by unexpected design.

The purpose of this study was to confirm the optimal spinning conditions for PLA (Polylactic acid) as a fiber forming polymer. According to the melt spinning test results of PLA, the optimal spinning temperature was 258℃. However, it needs to note that relatively high pack pressure was required for spinning at 258℃. At an elevated temperature, 262℃, mono filament was broken easily due to hydrolysis of PLA at a higher temperature. In case of fiber strength, it was confirmed that the draw ratios of 2.7 to 3.3 were optimal for maximum strength of melt spun PLA. Above the draw ratio, 3.3, the strength of the PLA fibers was lowered. It was presumed that cleavage of the PLA polymer chain over maximum elongation. The heat setting temperature of GR (Godet roller) showed that the maximum strength of the PLA fibers was revealed around 100℃. The degree of crystallinity and the strength of the PLA fibers were decreased above 100℃. The optimal take-up speed (Spinning speed) was around 4,000m/min. Thermal analysis of PLA showed 170℃ and 57℃ as Tm (melting temperature) and Tg (glass transition temperature), respectively.

The MZ Generation likes watching YouTube videos produced by senior influencers despite the big age gap. In addition, the final goal of collaborative YouTube videos between senior influencers and brands is to increase sales. Accordingly, this study examined this interesting phenomenon and aimed to provide useful insights for creating YouTube videos targeting the MZ generation. This study was divided into two parts. Study 1 explored the viewers' perceived benefits by looking at the YouTube video comments of a senior fashion influencer, and then classified the perceived benefits into informational, psychological, and hedonic benefits. Study 2 analyzed the relationships among the viewers' perceived benefits (informational, psychological, hedonic benefits), attitude toward a brand, and behavior intention. Study 2 found that only informational benefits, among the three perceived benefits, enhanced attitudes toward a brand, thereby affecting behavior intention. Based on the results of two sub-studies, this study highlights the importance of informational benefits to maximize the marketing effects employing the collaborative YouTube videos of senior influencers and brands.

In this study, the effect on flame retardancy and various physical properties when TiO₂ was added with a citric acid/phosphate complex acid catalyst together with Pyrovatex CP new (N-methylol dimethylphosphonopropionamide), a phosphorus-based flame retardant, was studied on cotton fibers. SEM-EDS analysis was performed to confirm the surface characteristics and surface element analysis of the flame-retardant treated cotton fibers, and a vertical carbonization test was performed to confirm the char formation capability and flame retardancy according to the phosphoric acid ratio. By comparing the LOI index before and after washing 10 times, the washing durability of the flame retardant solution containing the phosphoric acid catalyst and TiO₂ was tested by LOI index after ten washing cycles. In addition, the influence of the flame-retardant processing on the physical properties were compared including thermogravimetric analysis (TGA), tear strength and whiteness.

차세대 하이테크 스마트 의류는 복합 차원에서의 감성적인 요소를 섬유 패션기술에 IT융합 기술을 이용하여 제공하고 있다. 생체신호를 이용한 감성은 모호하여 정량적이고 객관적인 측정이 어렵고, 그 표현도 제한된 감성 어휘에 의하여 나타나기 때문에 구체적으로 파악하는 것은 어려운 일이다. 이를 위하여 제품의 기능적 측면뿐만 아니라 정서적 감정과 선호도가 반영된 제품의 설계나 디자인 또한 요구되고 있다. 본 논문에서는 생체신호 측정을 위한 웨어러블 기반의 심전도 측정 의복을 제안하였다. 착용자가 평소 자주 입는 티셔츠를 응용하여 답답해하거나 불편하지 않게 제작하고 소매 형태로 신축성있는 소재를 사용한다. 인체의 형태에 따라 의복과 바이오센서의 전극이 안정적으로 밀착될 수 있도록 고탄력 밴드를 이용하여 일자형으로 제작하였다. 심전도 측정 의복을 착용에 의해 수집된 심전도 ECG 파형을 수집하고 심박변화율을 계산하는 시뮬레이션을 개발한다.

In this study, as one of the eco-friendly dyeing methods, indigo, Phellodendron amurense and Caeasapinia sappan were complexed dyed on cotton fabric. For complexed dyeing, the cotton that was pre-dyed 5 times with indigo was dyed 1 ~ 2 times repeatedly with Phellodendron amurense and Caeasapinia sappan. Then the color, tensile strength, density, and color fastness of complexed dyed sample were analyzed and the following analysis results could be obtained. As a result of color difference measurement, the L* value was 22.7 in the sample in which the cotton was dyed 5 times and then the Phellodendron amurense was dyed 1 time, and the K/S value was 15 or higher in all samples. As a result of measuring the strength, cotton fabrics tended to have a slight decrease in tensile strength when complexed dyeing. As a result of measuring the density, the density decreased by 15 ~ 20% in all samples at the warp and increased by 20 ~ 30% in the weft due to the complexed dyeing of cotton fabric. Moreover, the fastness to washing and drycleaning showed good results of 2 ~ 3 or higher, and the light fastness was 4 or higher.

This study developed e-book content in order to use e-books as a tool to provide more efficient classes to learners who are familiar with smart devices and online spaces. E-book contents were produced using Sigil-0.9.10. The development process is as follows. Before e-book development, it is necessary to prepare manuscript files, image files to be inserted, fonts to be used, and e-book covers. After inserting the book cover images, it is necessary to register the table of contents using the title tag and register the free fonts. Also, a style must be created for text or images used in the main text connected to a file containing the entire text. Then, after separating the entire text file into separate files according to each chapter, the text is completed in turn. E-books were produced focusing on hyperlink functions so that educational content and various example images could be accessed. Currently, there is a lack of research on e-books as textbooks in universities within the fashion design major. In the future, if e-book contents are developed according to the characteristics of courses and the level of learners, they can be used as effective teaching tools.
