Wearable e-textile near-field communication (NFC) radio-frequency identification (RFID) antennas fully integrated with garments using embroidery techniques, which enables everyday clothing to become ...connective to wireless communication systems, is presented. The e-textile wearable antennas have been designed through full electromagnetic wave simulation based on the electrical properties of conductive threads and textile substrates at the high frequency band, allocated for NFC wireless communications. The e-textile wearable NFC antenna performance under mechanical bending as well as human body effects have been experimentally studied and evaluated; the antennas can operate under significantly bending angle and body effects attributed to its broad operating bandwidth. This is highly desirable and distinguished to conventional NFC antennas; the proposed e-textile wearable NFC antennas can be placed almost any place on clothes and still capable to communicate at the desired operating frequency of 13.56 MHz. The maximum read range of the e-textile wearable NFC tags is measured to be around 5.6 cm, being compatible to typical commercially available metallic NFC tags. The e-textile wearable NFC tags can lead to numerous potential applications such as information exchange, personal security, health monitoring and Internet of Things.
The clothing and textile industry is a resource-intensive industry and accounts for 3 to 10 percent of global carbon dioxide emissions. In addition, the industry is extremely linear and generates ...large amounts of waste. For the industry to move from a linear to a circular economy, several solutions are required along the value chain: upstream by working with resource efficiency, the longevity of textile products, and preventing waste; and downstream with techniques for sorting and recycling. In addition, solutions for traceability and transparency need to be developed and coordinated as accepted methods for sustainability measurements. This Special Issue (SI) "Sustainable Fashion and Textile Recycling" brings together areas of knowledge along the textile value chain to highlight the difficulties and opportunities that exist from both a broader perspective and in specific issues. In this SI, these 11 papers are mainly devoted to new research in traceability, design, textile production, and recycling. Each valuable article included in this Special Issue contributes fundamental knowledge for a transformation of the textile and fashion industry to take place. Numerous studies, solutions, and ideas need to be carried out to create the innovations that will become the reality of our future. Likewise, we need to learn from each other and take advantage of all the fantastic knowledge that is generated globally every day towards a better future for generations to come.
Wearable e-textiles are able to perform electronic functions and are perceived as a way to add features into common wearable textiles, building competitive market advantages. The e-textile production ...has become not only a research effort but also an industrial production challenge. It is important to know how to use existing industrial processes or to develop new ones that are able to scale up production, ensuring the behavior and performance of prototypes. Despite the technical challenges, there are already some examples of wearable e-textiles where sensors, actuators, and production techniques were used to seamlessly embed electronic features into traditional wearable textiles, which allow for daily use without a bionic stigma.

España, de nuevo, se mostraba diferente, haciendo gala de una mayor capacidad de adaptación que Francia, pero adoptando ?una política fiscal de perfil bajo?, sin el margen y la habilidad para innovar ...británica. La enorme demanda que generaba esta necesidad se veía acentuada por las dificultades para cultivar cáñamo en la Europa occidental, que tenía que ser importado en ingentes cantidades desde territorios pertenecientes al Imperio ruso, en el arco geográfico que recorría Europa del Este del Báltico al Mar Negro. Lo hace además desde el escenario del Pacífico y Filipinas, de enorme importancia en las redes comerciales del Imperio español, en cuya coyuntura debe adaptarse a un medio diferente -que lo es también a la hora de construir embarcaciones-, a las sociedades existentes en la zona, a los competidores locales y a los propios colonos españoles, hasta el punto de concluir que los intereses ?del comercio transpacífico? eran capaces de imponerse, en la propia construcción naval, a los intereses militares (p. 259). Julio L. Arroyo Vozmediano (UNED) trae a colación la figura de Thomas Mun, personalidad esencial en la evolución del pensamiento económico anglosajón a partir del mercantilismo clásico -en esencia, la idea de que la riqueza viene del comercio exterior, haciendo de la carencia de riquezas naturales motor de fomento de la industria y el comercio y el reconocimiento social hacia el comerciante- y que tiene su actividad en la primera mitad del siglo XVII.
This study focuses on the making of African bark-cloth in the Caribbean and the use of plant fibers and pigments in the production and care of clothing for members of the colonized population. The ...material artifact of interest in this study is lace-bark, a form of bark-cloth, obtained from the bark of the lagetto tree found only in Jamaica, Cuba and Haiti. The fibres of the lagetto bark were removed by hand and dried, and the end result resembled fine lace or linen that was used by enslaved and freed women in Jamaica to make clothing as well as a substitute for manufactured lace. Although lace-bark is derived from the bark of a tree, it is different from other forms of bark-cloth. For instance, unlike most bark-cloth, the bark of the lagetto tree was not beaten into malleable cloth. The scientific name for the lace-bark tree is Lagetta lagetto; however, common names and spelling vary across regions. The author argues that a vibrant cottage industry based on African bark-cloth and lace-bark developed in Jamaica in response to economic conditions, and the insufficient clothing enslaved Africans received from their enslavers. Women dominated this industry and it fostered a creative space that allowed them to be expressive in their dress and simultaneously to escape, at least temporarily, the harsh realities of the plantation. The subjects of this study are women of African ancestry living in Jamaica from the seventeenth to the early twentieth century. By the late seventeenth century, a bark industry had developed in Jamaica that was responsible for producing exquisite bark material that was widely popular. The laghetto tree was known in Cuba as the Daguilla, and in Haiti as bois dentelle.
The textile sector is 14% of total industrial production in India and contributes to about 4% of the gross domestic product and earns about 27% of India's total foreign exchange. Worldwide, up to ...10,000 dyes are available and their annual production is above 7 × 10
5
metric tons, which are being used not only in textile sector but also applied in paper, food and pharmaceutical industries. Textile industries in India have been consuming more than 100 L of water to process 1 kg of textiles, and have contributed heavily in polluting surface and ground water resources in many regions of the country. The toxic and carcinogenic effect of untreated textile effluent is well understood. The decolorization and detoxification of industrial dye effluents is most important aspect and is major concern to meet environmental regulations. This paper presents a review of literature on the significance of bioremediation technologies over other physico-chemical methods for efficient removal of textile dyes from industrial waste effluents to improve the fragile ecosystems in different regions of the world.
The present review paper (a) symbolizes the applications of existing conventional physical and chemical approaches for the decolorization/degradation of textile dyes, (b) describes their merits and demerits, (c) emphasizes on the existing literature on microbial decolorization of textile dyes precisely by using bacteria (aerobic and anaerobic conditions), fungi and algae, and (d) involvement of various enzymes from different biological sources for the decolorization of various textile dyes and their mechanism of action.
Over the years, researchers have developed several bioremediation technologies to treat textile effluents, but little effort has been made to put the entire literature review of these technologies in one refereed paper, our review paper is an attempt to compile the existing information on various treatment technologies of textile effluent, so that these technologies can be shared widely for site specific situations.
Print is an exciting and dynamic design area, with new analog and digital technologies opening up a wealth of creative possibilities for designers in textile and non-textile media. Witty, hyperreal, ...and luxurious print designs are being used by fashion designers and in interiors, while fine artists are harnessing the latest technology in their work to stunning effect. This showcase of contemporary print designs from around the world is divided into three key areas: fashion, interiors, and art. In fashion, the book features innovative print designs in haute couture, prêt-a-porter, and accessories from companies such as Prada, Issey Miyake, and Vivienne Westwood. The interiors section shows surfaces and interior products such as wallpaper, upholstered furniture, fabric hangings, and floor coverings, and features a wide range of designers from Marimekko in Finland to Anna Glover in the UK. Fine-art prints and experimental work from international artists and designers such as Cristian Zuzunaga and Liberty Art Fabrics are represented in the final part.
Washability is seen as one of the main obstacles that stands in the way of a wider market success of e-textile products. So far, there are no standardized methods for wash testing of e-textiles and ...no protocols to comparably assess the washability of tested products. Thus, different e-textiles that are deemed equally washable by their developers might present with very different ranges of reliability after repeated washing. This paper presents research into current test practices in the absence of e-textile-specific standards. Different testing methods are compared and evaluated and the need for standardized testing, giving e-textile developers the tools to comparably communicate and evaluate their products’ washability, is emphasized.
