Textile UWB antennas for wireless body area networks

A new ultrawideband (UWB) textile antenna designed for UWB wireless body area network (WBAN) applications is presented. Unlike previous textile antennas, these antennas offer a direct integration into clothing due to a very small thickness (0.5 mm) and flexibility. We have realized two different designs of textile antennas: coplanar waveguide fed printed UWB disc monopole and UWB annular slot antenna. To our knowledge, these are the first textile UWB antennas reported in the open literature. Measured return loss and radiation pattern characteristics of textile UWB antennas agree well with simulations. Moreover, measured transfer functions show that these textile antennas possess excellent transient characteristics, when operating in free space as well as on the human body. They can operate in the entire UWB band approved by the Federal Communications Commission (3.1-10.6 GHz)A new ultrawideband (UWB) textile antenna designed for UWB wireless body area network (WBAN) applications is presented.

The benefit of textile design research to the textile designer.

If Textile Designers do not embark on and utilise textile research we will be left in a ‘sole less’ vacuum. The following article aims to show the benefit of textile design research to the textile designer. Textile design is increasingly complex, and influenced by a number of factors such as ethical textiles, sustainability, fast versus slow fashion, new digital technology and science. It is therefore necessary for increased research by the textile designer into these areas in order to understand and gain knowledge that can be incorporated into the vast textile industry so that we produce the most relevant cloth and fabrics, that satisfy both consumer and ethical requirements. “Work on good prose has three steps: a musical stage when its composed, an architectonic stage when its built and textile stage when its woven” Walter Benjamin 1892-1940.

A review on the present situation of wastewater treatment in textile industry with membrane bioreactor and moving bed biofilm reactor

Membrane bioreactor (MBR) is one of the advanced treatment technologies used in industrial wastewater treatment due to its various advantages over conventional biological processes. Recently, the application of MBR in treatment of textile wastewater has increased significantly with an effective removal of contaminants. Moving bed bioreactor (MBBR) has been efficiently used for the treatment of different municipal and industrial wastewater during the last decades and it is a relatively novel and effective technology applied in textile wastewater treatment. This review paper presents the situation of MBR and MBBR technology for textile wastewater purification under different conditions and collates results of previous studies during the past years about MBR and MBBR treatment technologies used in textile processes. Both of these two technologies have shown their efficiency, but they still have problems in textile wastewater treatment. To this end, MBR-MBBR hybrid system could be an attractive solution for textile wastewater purification because of the high efficiency and low consumption of energy and spacePostprint (author's final draft

Textile art promoting well-being in long-term illness: Some general and specific influences

The paper reviews previous research into the meanings of textile art-making for people living with long-term illness. Qualitative accounts of the creative process suggest that textile art-making is a multi-dimensional experience. Some practitioners regard textile artwork as a means of coping with discomfort and other symptoms. For a minority, it enables expressions of anxiety and feelings about loss. Nevertheless, participants place more emphasis on the role of textile art-making in rebuilding a satisfactory identity, and restoring autonomy and quality to life. It fills occupational voids following early retirement, and enables social contacts. Textile artwork also stimulates learning and personal development. It remains possible that any creative occupation delivers such benefits. The paper analyses qualitative accounts from seven participants to identify whether textile art-making has any distinctive experiential qualities. As a creative occupation, it seems to be quite distinctive in being readily accessible even to those who do not consider themselves as artistic. Modern textile art embraces diverse techniques and forms, and practitioners’ choice and autonomy are enhanced by having several different projects in process at once. It accepts the use of assistive technology, thereby enabling people with a variety of physical impairments to produce ‘mainstream’ art. It draws upon rich social traditions, facilitating social contact. Many forms of textile art-making are highly time-consuming, fostering a future orientation, and the creative process is often socially visible within the home, with positive consequences for self-image. This study is exploratory. Further enquiry into the distinctive influences of different creative occupations upon well-being is recommended

Green textile dyeing process by using natural dyes: a review

In the textile industry, up to 200,000 tons of dyes are lost to effluents every year during the dyeing and finishing operations, due to the inefficiency of the dyeing process. Today, the textile industry used average six hundred dyes and chemical for the in production of textile dyeing industry (Christy, 2014). Due to the toxicity of dyes and chemicals used in textile dyeing processes has led to both human health and environment directly or indirectly. Therefore, “Go-green” or going green is one alternative way to maintain the sustainability and productivity of textile dyeing industry hence maintaining natural ecological balance in the environment and preserving its natural system and resources. The textile dyeing industry makes a big contribution to the economic growth and has become a massive industry throughout the years. This is because higher demand in the production of synthetic dyes since they are affordable, good colour fastness, has various of colours available and are easy to manufacture. However, the environmental impact arising from these industries aroused attention in today’s society. In terms of pollution, the textile dyeing industries has been condemned as one of the world’s most offensive industry among other sectors in the world. In fact, World Bank stated that textile processing polluted 20% of water pollution globally

Behaving badly? The conservation of modern textile art

Textile conservators are increasingly likely to be asked to treat modern textile artworks. These often present new challenges: they may be made of unusual materials whose deterioration patterns are unfamiliar, they may utilise traditional textile techniques in unusual ways. Modern artworks may be hung in unconventional ways, or be displayed in spaces which are not standard museum venues. It is commonly accepted that it is necessary to gain as much information as possible in order to preserve the artist’s intent when treating modern artworks. Legislation also gives the artist moral rights over his or her work. The issues involved in the conservation of modern textile artworks are illustrated with examples of pieces treated at the Textile Conservation Centre, UK, among others, and with particular reference to a piece by Robert Rauschenberg
