This motor drive system is especially suitable for machine tools the high position accuracy and repeatability. This paper describes about that need of the embroider machine, we want to design position-scanning device for the embroidery machine. At first, to be analysed characteristics of the machine and next designed the LPM. we used the field analysis program, The finite element method(FEM) program tool is employed for calculation the force.

The purpose of this study is to provide basic information about various methods to easily affix unique embroidery effects to clothes due to the current expansion of digital fashion technology. A comparison of design techniques using virtual and real clothing was used to show the visual expression of embroidery designs. Actual embroidery motifs were created using a computer embroidery machine, DTP embroidery motifs were made by utilizing digitalization techniques, and digital motifs were produced. Then patch pocket type T-shirts were produced using each embroidery technique to compare the visual expression effects on clothing. The results of this comparison are as follows: for real clothing color (3.5), texture (4.0), gloss (3.8), and thickness (3.5). It was found that the color and thickness of the embroidery floss was visually sufficiently show the design texture and gloss. In terms of the embroidery design on virtual garments, the resutls of color (3.8), texture (4.3), gloss (3.9), and thickness (3.6) showed a high degree of similarity to the non-virtual results, confirming that digitized embroidery motifs are also a tool that can fully realize unique embroidery effect.

In this paper, the color matching algorithm is Proposed for stitching machine. The matched embroidery color threads are selected by using the proposed algorithm from a computer files which is designed on the computer or scanned from the drawings designed by an artist. The proposed algorithm finds the best matching nearest colors from the given embroidery color threads . The multiple candidates owing to have the equal distance in the CIE color space are further processed to find nearest dominant color. The color dithering method will be useful for reproducing original design with high fidelity.

Silk, polyester, cotton, and wool fabrics were embroidered with varying stitch length of 3mm, 5mm, and 10mm to examine the difference in fabric shrinkage in terms of sewing direction, fabric thickness, cover factor, stitch length, and fiber type. Warp, filling, and bias direction of sewing resulted in no difference in fabric shrinkage. Within the samples with same stitch length, there was less fabric shrinkage in fabrics with higher fabric thickness or higher cover factor. There was larger shrinkage when sewn with longer stitch length. Comparing fabrics with different fiber types but similar fabric thickness, silk and polyester fabrics showed the smallest fabric shrinkage and wool fabrics showed the largest shrinkage. It is shown that similar fabric shrinkage between silk and polyester is due to the similarity in cover factor.

This study aims to expand the scope of use for relics by applying the patterns and characteristics of embroidered fabric pieces, such as gold foil, excavated from the Mireuksa Temple Site in Iksan for fashion products. The artifact was a ra decorated with flower and vine patterns, embroidery using gold and red thread, and the unique stitching of Baekje. The pattern was reconstructed, as the embroidery was not well-preserved. This study used two types of gold-foil techniques: laser-cut and stone-stamp gold foil. Considering practicality, the gloss, toughness, custom production possibility, and design implementation were emphasized. The form of the laser-cut gold foil could be transformed; however, a recognition problem with the machine increased the thickness of the stitching. It was used for half-finished goods and commercial casual fashion. The stone-stamp gold foil was finely implemented, but the design was difficult to change. It was used for half-finished silk fabric for making hanbok po and lattice-patterned silk skirts. Applying the developed gold foil to suitable clothing can further enhance the effect.

In this study, we investigated the necessary mechanical properties of conductive multifilament yarns for fabricating the electrodes of biosignal measurement pressure and stretch textile sensors using embroidery. When electrodes and circuits for smart wearable products are produced through the embroidery process using conductive multifilament yarns, unnecessary material loss is minimized, and complex electrode shapes or circuit designs can be produced without additional processes using a computer embroidering machine. However, because ordinary missionary threads cannot overcome the stress in the embroidery process and yarn cutting occurs, herein, we analyzed the S-S curve, thickness, and twist structure, which are three types of silver-coated multifilament yarns, and measured the stress in the thread of the embroidery simultaneously. Thus, the required mechanical properties of the yarns in the embroidery process were analyzed. In the actual sample production, cutting occurred in silver-coated multifilament rather than silver-coated polyamide/polyester, which showed the lowest S-S curve. In the embroidery process, the twist was unwound through repetitive vertical movement. Further, we fabricated a piezoresistive pressure/tension sensor to measure gauge factor, which is an index for measuring biological signals. We confirmed that the sensor can be applied to the fabrication of embroidery electrodes, which is an important process in the mass production of smart wearable products.

This paper presents an investigation into the development of a fabric electronics based smart bag for festival users of the 2029 generation with customizable tech flaps (music media control/ LED animated graphic functions) based on the application of traditional Korean patterns and goblin patterns in an electric circuit. The investigator took into consideration functional and design strategies to enable custom service according to users' tastes and situations. Based on these considerations, a customizable smart bag platform was proposed in a detachable module based on a computer embroidery machine. The study is significant in that it developed a product that is different from the old PCB smart products in hard form and proposed a new business model.

This study examines decorative features found in the traditional costume of the Miao, one of the minority groups in China, and adapts them for the development of modern Korean-style fashion designs in order to present visual sample data and to introduce techniques. As for the research method, both literature and visual data are examined: the former includes Miao-related books and theses; the latter, pictures from various documents and real-life data in the possession of Seoul Women's University. The study result is as follows: 1. The basic structure of Miao costume is consist of a Caftan-type upper garment and an accentuated lower garment, pleats skirt although they are decorated luxuriously with various techniques such as delicate embroidery and dyeing. 2. Details and trimmings in modern shapes are developed and presented by adding modern materials to satin, twists, cross-stitch embroidery, stripe patterns, geometrical patchwork, machine pleats and smoking, trimmings of fringe & feather, and the border line decoration of coloration, braids, piping, embroidery, belts tied and wound with colorful threads. 3. Detachable accessaries such as front reinforcement strips, back reinforcement strips, belts, decorative aprons and patchwork skirts are developed and designed by adapting highlighted layered effects. 4. The silver decoration used as an necessary by the Miao is suitable for modern fashion design in futuristic sense. Various techniques and decorative features of Miao costume display their true value all the more in modern fashion stream in which ethnic trends draw much attention.
