Implementation of Steel-based Fabric Panels in a Heated Garment Design

The smart/interactive textile structures that integrate electronics and textile materials have realized their great potential in recent years. The garments, which can heat the body, will possibly be one of the most widely used products as electrotextiles for future use in daily life. In this study, steel-based conductive yarns were used to produce heating panels within the study about interactive electronic heated garment design. Portable power supplies were applied to fabric-based panels to obtain a heating function. In addition to an electronic circuit, a functional garment containing all of the systems was designed and produced. The performance of the heating garment prototype was evaluated on a thermal mannequin by testing in cold weather environments.

Heating behaviors of metallic textile structures

Purpose – The purpose of this paper is to investigate the concept of “electrically conductive fabrics”. The primer applications that import electrical conductivity properties to textiles and clothing are summarized. Also the heated fabric panels produced by steel yarns are evaluated. Single and multi‐ply steel fabrics are applied to electrical current and their heating behaviors are observed and compared.Design/methodology/approach – The integration of electronic components with textiles to create very smart structures is getting more and more attention in recent years. Most of the textile materials are electrical insulators. Hence, various types of fibers and fabrics having reasonably good electrical conductivity are required especially for electronically functional apparel products. The textile‐based materials being flexible and easily workable are the most preferred one in such cases. In this study, the steel yarns are placed in the fabric construction owing to their flexible characteristics. The heati...

Electromagnetic shielding efficiency of nonwoven insulation panels designed with recycled textiles and copper wires

Insulation applications of nonwovens has become increasingly important in the construction and automotive industries since the late 1990s. Besides, recycling and reusing fibrous waste becomes one of the most important raw materials of nonwovens to promote effective use of resources recently. On the other hand, metals are now being increasingly replaced by thermoplastics for housing commercial equipment, due to flexibility, light weight, and low cost for electromagnetic shielding purposes. In this study, we design nonwoven insulation panels containing copper wires with different intensity and length to provide electromagnetic wave protection by using recycled textiles. The method is simple, the material is cheaper, and more importantly, the whole material can be produced by using only waste materials. The electromagnetic shielding characteristics of the panels were measured and discussed. The experimental results indicated that the variation in wire length and amount affects the electromagnetic (EM) shielding property. With this method, the products with electromagnetic shielding effect in certain areas can be developed. In particular, there is a big potential for electromagnetic shielding applications in wide bandwidth, such as 1125–2925 MHz.

Active T‐shirt

Purpose – The purpose of this paper is to realize an electronic circuit design on the fabric surfaces to form a fully integrated functional active T‐shirt structure.Design/methodology/approach – Functional products combining textile, electronics and the software have attracted great attention in recent years. The integration of the electrical and electronic devices on the garment surface using conductive threads is a challenging issue considering conductiveness, long durability, washability and manufacturing process. As an application, a group of light emitting diode (LED) lights controlled by a light sensor, accelerometer and related electronic control circuits were placed on a fabric construction.Findings – The brightness of LED lights is controlled by using a light sensor depending on the perceived ambient light intensity. LED lighting patterns are controlled by means of an accelerometer which senses the physical activities of the wearer, such as walking, running and standing.Originality/value – In thi...

Design Methodology And Performance Studies Of A Flexible Electrotextile Surface

Abstract ‘The smart textiles’ concept has to develop products based not only on design, fashion and comfort but also in terms of functions. The novel electro-textiles in the market open up new trends in smart and interactive gadgets. ‘Easy to care and durability’ properties are among the most important features of these products. On the other hand, wearable electronic knitwear has been gaining the attention of both researchers and industrial sectors. Combining knitting technology with electronics may become a dominant trend in the future because of the wide application possibilities. This research is concerned primarily with the design methodology of knitted fabrics containing electrically conductive textiles and especially in-use performance studies. The structural characteristics of the fabrics have been evaluated to enhance the performance properties.
