The garment manufacturing industry is a labor-intensive industry, with one of the slowest transitions to automation. Hence, it essential build smart factory based on automated systems improve productivity and allow responsive production in market. In this study, processes for sports bra were established optimized using various machines. For system, computer-based 3D virtual design software, technical embroidery machine, an automatic cutting industrial robot arm gripper, pattern sewing...
Abstract A basic study was conducted to manufacture conductive composite threads for use in textile-type electrodes and circuits smartwear that can be sewn, embroidered, knitted. The two-types of poly(ethylene terephthalate(PET) filament with a circular cross-section(SD), an oval cross-section curved surface(DT), the yarn selected as silver-coated polyamide(AP). samples were produced two-ply PET first twist, then using AP second both processes applied 100, 200, 500, 1,000 TPM. As number...
Abstract This study fabricated and evaluated the textile-type electrodes for application to smartwear that can measure surface electromyography(sEMG). It was manufactured by lock stitch(LS) moss stitch(MS), stitch distance prepared as 1, 2, or 3 mm. The compression property measured using Kawabata evaluation system, sheet resistance skin-electrode impedance were analyzed. coefficient of friction(MIU) MS larger than LS. On other hand, geometrical roughness(SMD) showed a smaller value. When...
Ag/AgCl hydrogel electrodes, which are wet generally used to acquire bio-signals non-invasively. Research concerning dry electrodes is ongoing due the following limitations of electrodes: (1) skin irritation and disease when attached for a long time; (2) poor adhesion sweat; (3) considerable cost disposable use. Accordingly, in film, embroidery, knit forms were manufactured from conductive sheets yarns, typical textile-type electrode materials, using different manufacturing methods...
The smart textile industry has become increasingly interested in products with electronic functions. In these products, sensing and data communication are conducted through conductive circuits by threads. embroidery technology that uses threads as the material for line a circuit, their resistance is an important factor when designing product. main purpose of this study was to derive equivalent circuit model calculation equation consumption according design parameters. effects parameters on...
Wearable 2.0 research has been conducted on the manufacture of smart fitness wear that collects bio-signals through wearing a textile-based electrode. Among them, electromyography (EMG) suit measures electrical signals generated by muscles to check their activity, such as contraction and relaxation. General gel-type electrodes have reported cause skin diseases due an uncomfortable feel irritation when attached for long time. Dry various materials are being developed solve this problem....
This study aimed to establish an automatic sewing process for garment production according textile properties. An feeding system and a self-made template were introduced industrial machine. Two types of stitches performed on fabrics with various physical properties surface roughness using this The appearance, stitch length width, seam strength, efficiency evaluated the conditions, such as presser height speed. In addition, correlation between properties, sewability was analyzed derive...
Textile thermocouples, designed with conductive yarns by embroidery, was developed for measuring of temperature. Electromotive force (emf) them measured in the temperature range between 20℃ and 40℃. The emf embroidered thermocouple linearly increased experimentally Seebeck coefficient 21.96μV/℃. It considered that might be a candidate sensors more setretchable durable properties than metal embedded textile products.
