This study aims to propose various ways to utilize CLO, which focuses mainly on the production of 3D virtual samples, by comparing it with the pattern drafting functions of Four apparel CAD experts, who have teaching experience in YUKA and CLO, participated in a focus group interview, and a basic bodice prototype drafting was carried out by each participant to evaluate the pattern drafting functions of YUKA and CLO. The result of this study showed that the pattern drafting tools of YUKA are subdivided since YUKA is a CAD tool inherently specialized in pattern making. Though CLO provided a relatively limited pattern drafting menu compared to YUKA, it was found that pattern drafting could be accomplished with the help of supplementary tools and functions. This finding suggests that each CAD offers the corresponding tools for the same use of menus or functions in the prototype drafting process. The major difference between YUKA and CLO is that YUKA defines the pattern area by a set of line segments, whereas CLO utilizes an outline composed of closed curves. YUKA provides various specific tools according to the options such as angles, straight lines, and curves, while CLO produces the same results using combinations of a limited number of tools. Compared with YUKA, the advantage of CLO is its user-friendly task environment such as the Windows-based user interface, from the usability perspective. This study concludes that pattern drafting education using CLO would help not only industrial 3D design practitioners but also pattern education in academia

This study attempted to extract and structure the job skills required for 3D designers, which have been recently introduced to the fashion industry. The study aimed to materialize and objectify the 3D designer's job, using a focus group interview for the survey. The 3D designer has the TD task of making 3D virtual samples using the pattern files developed in Pattern CAD. Graphic design and fabric digitization are also major tasks for the 3D designer. CLO is mainly used for 3D virtual sample production, and PixPlant, Substance, Photoshop, Cinema 4D, Daz studio, and 3ds MAX are used for image and avatar editing. As per the job skills required for 3D design work, basic knowledge about patterns and sewing, skill in 3D virtual clothing technology, ability to use various software, and English skills were considered important, in that order. In particular, the need for knowledge about patterns and sewing became more important than the skill in 3D virtual clothing technology itself. To train 3D designers, it was found that not only 3D virtual clothing software, but also education on patterns and clothing construction, CAD developer's curriculum certification system, and 3D designer qualification management were required. In addition, 3D designers are recognized as an essential job in fashion vendors, and the demand for domestic brands is increasing. The biggest limitation of the 3D virtual clothing system is the perfection of the digital fabric. Also, technical improvement is needed.

This study was intended to compare the comfort of wearing each type of commercially available bralette. The trial wearing experiment was conducted on five women in their 20s who wear an average Korean bra size of 70A. The experimental bralettes were of four types: a bralette with both hooks and pads and a bralette without both, a bralette with hooks but no pads, and a bralette with pads but no hooks. The wearing test results are as follows. First, in terms of functional satisfaction, the padded bralette provided the greatest satisfaction in supporting the chest from the bottom up and bringing it to the center, and the bralette without the pad provided the least satisfaction. In addition, the level of convenience of attaching/detaching was about twice as high in the bralette with hooks than those without hooks. Chest compression was found to be greater in bralettes without hooks than in those with hooks. In terms of the pressure on the shoulder strap and on the lower chest band, it was found that bralettes with hooks had a greater sense of pressure than those without. In the appearance characteristics test, the unpadded bralettes scored higher than the padded one in the matter of feeling embarrassed, because in unpadded bralettes, the nipples were exposed underneath the clothes . This study is meaningful in classifying the design of the bralette and evaluating the fit for each design in the absence of prior research on the bralette.

This study had a purpose of further investigating and developing the usage of the eco-friendly functional dye that has physiological and pharmacological functions. This study was implemented complex dyeing method which used both natural dyes such as Gardenia jasminoides J.Ellis colorant, which are the yellow dyes that have high brightness and low chroma, and Xanthium strumarium L. extract. The silk fabrics were used to dye in various methods. They were also used to investigate functionalities dyed fabrics by various treating method, such as their color fastness, antibacterial activities and deodorization, the following were obtained. The fabrics that were dyed with herbs had decreasing brightness as the herbs extract concentrations were increased and had subtly changing chroma. But, because their K/S values were under 0.5, they were not properly dyed. Color fastness differed according to the natural dyes and herbs' complex dyeing order. The Color fastness was good when the fabrics were dyed with the colorant first, and then with the herb. When the fabrics were dyed with mixture dyeing solution, the natural dye and the herb extract, the herb didn't affect the dyeabilities of fabrics as much. When the fabrics were dyed with the mixture of the colorant and the herb extract, the dyeabilities didn't have much changes. However, their color fastnesses were improved a little bit due to the complex dyeing condition. When the fabrics were dyed with the mixture of the colorant and the herbs extract, their antibacterial activities and deodorization were increased.
