Since knitted textile products mostly do not require long span of time from the conception to the final products, they have lead the fashion trends during the recent decades. Developments in the textile engineering industries, and computer software and hardware industries have made the 3D virtual clothing software system easily accessible by the fashion/textile industry personnel. The simulated models of apparel products using the state-of-the-art virtual clothing systems are, however, not the replica of real-world garments. Moreover, the garments do not maintain fixed shapes during wearing. Deformations at low external stress lead to difficulties in predicting the behavior of the knitted garments. Therefore, there is a need to compare the differences in appearances, textures, or other related properties between simulated fabrics and actual fabrics. Three knit stitches including jersey, rib, and cable stitches are examined in this study. The differences between fluffy thick yarns and thin yarns are also compared using 3D scanning and surface reconstruction. Obtained three-dimensional data regarding the reconstructed knit specimens would help to build a data base for estimating the behavior of the 3D models of the knitted garments.

Knit industry requires versatile knit designers who have to control whole process such as material select, color, type of machine, technique, structure and shape. In other words, knit designers urgently need to interplay between technology and design aesthetics. It becomes essential to learn and master basic principles of knitting in order to design and develop effectively for innovative knitwear design. The main purpose of this study is to show fresh methodology through examining the various applications of 'Stitch transfer knitting structure' used in women's knitwear design development. Stitch transfer knitting structure is one of the most popular techniques among various basic knitting methods. Eight knitwears were designed and produced with various types of formative applications which differ from existent stitch transfer knitwears of flat and simple style in the market. These are produced by computer knitting machine 'Shima Seiki 122S' and programmed by 'Knit CAD' software. Among various basic stitch transfer pattern, 'Leaf' pattern is selected as a most effective example for this study. This fabric applied to collar, sleeves, body pattern and accessories as formative decoration. It is expected that this study of methodology helps to get open mind and to indicate possibility to develop and show creative and innovative knitwear and knitted textile design.

Textile scientists have regarded the material appearance of natural fibers, especially that of silk or wool fibers, as the benchmark for reinventing the look and feel of the long term, friendly companion of mankind. The appearances or textures of the materials surrounding us in everyday life have long been interesting topics to many people.from scholars to painters. Even the simplest questions may require careful pondering. Why is the silk fabric so lustrous with subtlety? Recently, appearance models have become increasingly important in textile products. They are needed to model and simulate different models. In this study, the optical characteristics of filament yarns and knitted fabrics were investigated using images taken at various angles and illumination conditions. Then the images were analyzed using some image analysis techniques, such as thresholding and measuring luster blobs. The anisotropic nature of the filamentous specimens was studied based on the images acquired at different incident illumination and observing angles with several alignment positions of the fabric specimens. A few cylindrical models were generated using commercially available software, Rhinoceros, and then on the models, a ray-tracing algorithm based on a software, POV-Ray, was applied to simulate the appearance or lustrous images of the monofilament models.

We have made knitwear in a different way from the typical woven pattern; it does not have the dart, even for women's tops. The purpose of this research was to compare the fit and appearance of the torso pattern for circular knitted fabric between virtual try-on garments and real garments. First, a woman in her 20's was scanned by a 3D body scanner, and thus producing a virtual avatar. I prepared knit patterns and created a torso pattern appropriate for circular knitted fabric. Next, I measured the body size of the avatar. The 2D patterns for the torso and sleeves were developed using the Yuka Super ALPHA : Plus. The 3D virtual garments were made from the imported 2D patterns and were then tried on the 3D virtual avatars. Finally, the fit of the real garments and the virtual garments was compared. While the shape of the virtual try-on garments were similar to the real garments, the folding and sagging were different. This study found the length was the same as woven wear. However the actual bust size and the clothing size were the same which is not a typical characteristic of woven wear. In the case of hem measurement, more space was needed than actual body size but less space was needed than in woven patterns.

This study investigates the social network among authors to improve the quality of Panel researches. Korea Health Panel (KHP), implemented by the collaborative work between KIHASA (Korea Institute for Health and Social Affairs) and NHIC (National Health Insurance Service) since 2008, provides a critical infrastructure for policy making and management for insurance system and healthcare service. Using bibliographic data extracted from academic databases, eighty articles were extracted in domestic and international journals from 2008 to 2014, April. Data were analyzed by NetMiner 4.0, social network analysis software, to identify the extent to which authors are involved in healthcare use research and the patterns of collaboration between them. Analysis reveals that most authors publish a very small number of articles and collaborate within tightly knit circles. Centrality measures confirm these findings by revealing that only a small percentage of the authors are structurally dominant, and influence the flow of communication among others. It leads to the discovery of dependencies between the elements of the co-author network such as affiliates in health panel communities. Based on these findings, we recommend that Korea Health Panel could benefit from cultivating a wider base of influential authors and promoting broader collaborations.

This research explores consumer preferences for materials in different clothing product categories, using web-crawling and text mining techniques. Specifically, the study focuses on the material-related terms found in consumer reviews across three distinct product categories: functional clothing, formal shirts, and knit sweaters. Top-selling products within each category were identified on the Naver Shopping website based on the volume of reviews, and the four most-reviewed products were selected. Six hundred reviews per product were analyzed using the Textom big-data analysis software to determine the frequency of material-related mentions and word associations. The analysis utilized two comparative metrics: product category and usage duration. Our findings reveal notable variations in the material preferences mentioned by consumers across different product categories. The study suggests a need to re-evaluate existing standardized review criteria to better reflect consumer interests specific to each product category. Additionally, an increase in material-related terms in reviews over one month indicates the potential importance of extending the duration of product reviews to enhance the accuracy of information that reflects longer-term consumer experiences with material quality.

Adjusting pressure level in the construction of athletes' tight-fitting garments by reducing the elastic knit pattern is a challenging subject, which influences the performance of the wearer directly. Therefore, in this study, relationship between the reduction rates of the basic pattern obtained from 3D human scan data and resultant clothing pressure was explored to improve the fit and pressure exerted by clothing. 3D scan data were obtained using Cyberware and they were transformed into a flat pattern using software based on Runge-Kutta method. Reduction rate was examined by subjective wear test as well as objective pressure measurement. As a result, difference in the length between the original 3D body scan data and the 2D tight-fitting pattern was 0.02$\sim$0.50cm (0.05$\sim$1.06%), which was within the range of tolerable limits in making clothes. Among the five garments, the 3T-pattern was superior in terms of subjective sensation and fit. The pressure of the 3T pattern was 2$\sim$4 gf/cm2 at five locations on the body, which is almost the same or a bit higher than that of Z-pattern. In the case of tight-fitting overall garment, the reduction rate of the pattern in the wale direction is more critical to the subjective sensation than the course direction. It is recommended that the reduction grading rules of course direction should be larger than that of Ziegert for a better fit of tight-fitting garments. In the case of wale direction, however, reduction grading rule should be kept the same as suggested earlier by Ziegert (1988).

형상기억합금(SMA)-섬유 액추에이터는 소프트 로봇 공학 및 웨어러블 기술을 포함한 다양한 분야에서 큰 주목을 받아왔다. 이러한 부드러운 액추에이터는 SMA와 단순 직물 섬유를 결합하여 개발되었으며, K 루프와 P 루프라는 두 가지 루프 패턴으로 편직되었다. 두 루프 모두 루프 헤드 형상으로 인해 반대 굽힘 특성으로 구별된다. 그러나 이러한 액추에이터 시트의 편직 공정에는 전문 지식과 시간이 필요하므로 편직 루프 작동 시트의 생산 비용이 높아진다. 이 논문에서는 전압을 가할 때 큰 변형이 발생하는 SMA 직물 기반 액추에이터의 변형을 평가하는 새로운 방법을 소개하였다. SMA 재료의 매우 비선형적인 구성 방정식으로 인해 수치 분석을 위한 분석 모델을 개발하는 것은 어렵다. 따라서 본 연구에서는 SMA 재료의 대변형을 고려하면서 SMA-섬유 액추에이터의 초기 설계에 사용할 수 있는 선형 구성 방정식을 활용하는 새로운 접근 방식을 제안하였다. 전기-기계연성 효과를 모델링할 수 있는 선형구성방적식은 ABAQUS의 UMAT을 사용하여 구현하였다. 이 등가 단위 셀 모델(EUC)은 K-루프와 P-루프의 실험적 굽힘 작동 결과와 비교하여 검증하였다.
