Among the components of rotary hooks, a core component of an embroidery sewing system, a study was conducted to apply metal injection molding to the manufacture of a hook body and a housing that was very difficult to mechanical working. The correlation of feedstock, a mixture of binder and SCM 415 metal powder, and properties of the pressure-volume-temperature interrelationship, viscosity, specific heat, and thermal conductivity were measured. Injection molds for the hook body and the housing were developed through injection molding analysis using these properties and conducted injection tests. Optimal injection gate position and number, injection pressure, and injection time were obtained through a comparison of analysis results with the experiment results.

The purpose of this study is to examine the type of stitch and designs of knitwears using handcraft ornament techniques. This paper will also go on to develop and merchandize high value generated by design development. Knit is largely divided into weft knit stitch and warp knit stitch which are respectively woven by weft knitting machine and warp knitting machine. For clothing, circular knit and flat knit are frequently used while plain stitch, rib stitch and purl stitch are perceived as the basic stitches. Denbigh stitch, cord stitch, atlas stitch, which belong to tricot stitch, are the basic of warp knit stitch. There are also numerous fancy fabrics adapting the previously mentioned stitches and these are made into solid pattern and yarn dyed pattern. The handcraft ornament techniques in knitwears design are embroidery, beads, sequin, stone, printing, applique and fringe, etc. By applying these techniques thus creative expression, which cannot be expressed in other fashion items, is feasible. The women's knitwears are tries by mixed and various techniques, develope to high value knitwears, escaping from simple and practical items.

Linear pulse Motor(LPM) are used a field where smooth linear motion is required, and it's position accuracy higher than that of a lead. According to the advantage such as simplicity of mechanical frame, high reliability, precise open_loop operation, low inertia etc LPM is applied largely where it have made motor of this kind more and more attractive in many application areas such as factory automation and high speed positioning. This paper is researched to analyze for thrust force characteristic of hybrid LPM. Both the thrust and normal force are very sensitive to the airgap and tooth pitches of the force and platen. To find the optimal design parameter on the hybrid LPM for the embroidery machine. For the field analysis, the finite element method(FEM) is employed for calculating the force. The reluctance models will be used the magnetic permeance of airgap under static-conditions. The forces between forcer and platen have been calculated using the virtual work mathod.

In this study, we developed a feasible structure of a textile-based inductive sensor using a machine embroidery method, and applied it to a non-contact type vital sign sensing device based on the principle of magnetic-induced conductivity. The mechanical heart activity signals acquired through the inductive sensor embroidered with conductive textile on fabric were compared with the Lead II ECG signals and with respiration signals, which were simultaneously measured in every case with five subjects. The analysis result showed that the locations of the R-peak in the ECG signal were highly associated with sharp peaks in the signals obtained through the textile-based inductive sensor (r=0.9681). Based on the results, we determined the feasibility of the developed textile-based inductive sensor as a measurement device for the heart rate and respiration characteristics.

This research explores the idea of digilog for fashion; it would help to conclude the uncertain mixed-phenomena and words as a neologism and find a fundamental concept that would be a reference for a lot of uncertain new words that have been occurring even this year. Furthermore, this research is aimed at analyzing how digilog has been reflected on the contemporary fashion and directing the ways towards the future of fashion. The digilog fashion design is the expression of a combination of opposite extremes, that is to say the combination of a paradoxical mix and directly-opposed elements. The outward expression of fashion design with digilog can be classified into several ways. First of all, it tends to use the elements of paradoxical expression; for example, applying high-technology to express a primitive and natural material. The analog expresses unprocessed. Secondly, using high-tech machine to express the texture of handicraft or rough embroidery. Lastly, digital printing(DTP) is applied to enlarge the several or the whole parts of a natural object or sensitivity. As a result of the analysis, the inside view of the contemporary fashion with digilog delineate followings; it is the attitude that claims to go back to the past and accepts the combination of nature and high-technology to get calmness in the rapidly changing modern world. And it is the will to fly from the utterly exhausted reality through the recurrence of the past when there used to be a lot of energies and used to live in affluence.

This paper describes the processes conducted in the analysis and conservation of suit worn by Yu Rim (1898-1961). The suit consists of a jacket and pants and is a typical Mao-style suit for independence activists; it is notable in that it was made of domestic wool. Inside the jacket, there is a machine embroidery of the name "Danju," a label of synthetic resin which reads "Daegu citizen's tailor's shop," and buttons engraved with "PUSAN SIN-HUNG." According to our textile analysis, the outer layer is composed of worsted wool while the lining is made from acetate. Damage to the garment from malodor and insects has been repaired, and the suit has been restored to its original shape by a conservation treatment that has reinforced the textiles. This conservation case can provide valuable research data on the preservation of modern and contemporary clothing. In addition, this study also attempts to estimate the date of suit worn by Yu Rim's production by comparing it with woolen suits produced around the same time and examining the clues associated with the relics. This is significant since it enhances the value of the cultural assets and provides detailed information on the historical transformation of domestic suits.
