Embroidery technologies are widely applied for developing decorative elements of original design in garments, for integrating threads intended for protection into garments and other articles. Nonconformity of the shape and dimensions of the embroidered element with the designed digital image is influenced by properties of embroidery threads and fibres, by the filling type, density of stitches and other technological parameters. The objective of the paper is to explore the influence made by properties of fabrics and by the direction of stitches of the actual embroidered element on conformity of the shape with one of the designed digital image. For the research, embroidery threads of different purpose as well as three woven fabrics have been selected. For preparation of test samples, round digital images have been designed filling the embroidery area in different stitch directions. Analysis of the results of the investigations has demonstrated that the shape and dimensions of the embroidered element failed to conform to the shape and dimensions of the designed digital image in most cases. In certain cases, e.g. when the stitch direction goes towards the middle of the embroidered element, a defect, i. e. hole, is observed due to considerable concentration of stitches in the centre of the element.
Purpose – Flexible light-emitting textile display is designed with floats for electronic elements covering and electronic contacts insulation what at the same time provides an opportunity to develop aesthetic design of the display in the single piece construction of material. The paper aims to discuss these issues. Design/methodology/approach – Display consists of interwoven electrically conductive yarns, non-conductive yarns and SMD LEDs connected to conductive yarns. Industrial jacquard weaving machine have been used, weave patterns were designed in PC-Edit software. Findings – Weave can be used as a tool to build and evolve electrotextile. Exploring weaving techniques and perceiving electronic circuit as a weave pattern, new approaches can be developed in electrotextile design field. Research limitations/implications – Connections of electronic elements and conductive textile materials still is actual problem what should be explored in further research. Practical implications – Flexible light emitting textile display can be used as output interface integrated into communication clothing by representing different animated images directly on clothing. Display also can be used for accessories, room and auto interior etc. applications. Originality/value – Paper describes method of light source integration directly into textile structure, combining functional and visual design of textile display.
Abstract. Intelligent biomedical clothes combine health problem prevention, comfort, convenience, entertainment and communication with fashion and make everyday life easier. Homecare and healthcare applications wireless, mobile networks and wireless sensors improve the existing monitoring capabilities especially for the elderly, children, chronically ill and also for athletes. Sensor nodes are generally battery-powered devices. Batteries add size, weight and inconvenience to portable electronic devices and require periodical replacement. Nowadays the human power is an alternative and attractive energy source. Energy, which is generated during routine and seemingly insignificant human motions, shows promise as an alternative to power embedded wireless, mobile networks and wireless sensors. This paper describes the prototype of a smart garment and offers several alternative integration places of generator's parts, which are based on the principle of operation of the electromagnetic generator. Seven variants of location are proposed, which are tested and analysed. During the research, analysis of the most optimal placement of generator's part in garment has been performed.
