COVID-19 has brought to the fore the issue of medical textiles as masks, gowns and other personal protective equipment (PPE) are necessary for safeguarding healthcare workers against virus infections. The use of mask specifically became more widespread among general public and the debate centered around the type of material of the fabric that can minimize spread of the virus from person to person and also be affordable. As the demand for PPEs rose the challenge for the scientific and manufacturing community has been to find a way to provide better protection while allowing for the safe reuse of these items. Team of researchers from University of Pittsburgh - Anthony J. Galante, Sajad Haghanifar, Eric G. Romanowski, Robert M. Q. Shanks, Paul W. Leu - has created a textile coating that can not only repel liquids like blood and saliva but can also prevent viruses from adhering to the surface. Their research titled, 'Superhemophobic and Antivirofouling Coating for Mechanically Durable and Wash-Stable Medical Textiles', was recently published in the journal ACS Applied Materials and Interfaces. Lead author of the paper, Mr. Galante, who is the Ph.D. student in industrial engineering at Pitt, says, 'Recently there's been focus on blood-repellent surfaces, and we were interested in achieving this with mechanical durability.' The coating is unique as it is able to withstand ultrasonic washing, scrubbing and scraping. Prof. Leu, co-author and associate professor of industrial engineering, says, 'The durability is very important because there are other surface treatments out there, but they’re limited to disposable textiles. You can only use a gown or mask once before disposing of it. Given the PPE shortage, there is a need for coatings that can be applied to reusable medical textiles that can be properly washed and sanitized.' Prof. Romanowski, Research Director at Charles T. Campbell Microbiology Laboratory, says, 'As this fabric was already shown to repel blood, protein and bacteria, the logical next step was to determine whether it repels viruses. We chose human adenovirus types 4 and 7, as these are causes of acute respiratory disease as well as conjunctivitis (pink eye)...As it turned out, the adenoviruses were repelled in a similar way as proteins.' Prof. Shanks, Director of Basic Research in the Department of Ophthalmology at Pitt, says, 'Adenovirus can be inadvertently picked up in hospital waiting rooms and from contaminated surfaces in general. It is rapidly spread in schools and homes and has an enormous impact on quality of life - keeping kids out of school and parents out of work. This coating on waiting room furniture, for example, could be a major step towards reducing this problem.' The next step for the researchers will be to test the effectiveness against betacoronaviruses, like the one that causes COVID-19. Read on...

Team of researchers from Poland's Łódź University of Technology (ŁUT) led by Prof. Katarzyna Grabowska, the dean of the Faculty of Material Technologies and Textile Design, have developed a textile charger, which allows to charge phones, tablets, and other portable electronic devices using the power generated by their users' physical activity. Monika Malinowska-Olszowy, the vice dean of the faculty and member of the research team, says, 'The textile charger for mobile electronic devices is an inseparable part of the fabric or knitwear from which it is made, such as clothing...This invention replaces heavy, large batteries and power banks that often contain toxic substances. It is shock resistant and weatherproof. The main purpose of this technology is to ensure its users with uninterrupted access to electricity to sustain the operations of their mobile devices. As a result, this will exclude various problematic processes related to frequent charging of mobile phones or tablets.' ŁUT research has focused on the development of innovative textile inventions. Some of the latest examples include textile clothing for premature infants that is to protect them against dehydration and ensure thermal stability through special layered textile systems, and a prototype textronics solution that allows the integration of muscle-stimulating electrodes within various types of clothing, such as underwear, wristbands and socks, and use it to treat patients with various diseases that require such stimulation, among others.

Financial crisis of 2008 in US became a catalyst for the 'Tiny House' movement. Environmental considerations are also reasons for the popularity of the concept. Tiny house is typically 100 and 400 ft². Modular housing is also gaining ground in the construction world driven by lower costs, more predictability, and a shortage of construction workers. Italian architect Beatrice Bonzanigo is preparing to showcase her miniature house 'Casa Ojalá' in April. Casa Ojalá is a self-contained modular home design, measuring only 27 m² (290 ft²). The circular home can be arranged in 20 different ways by adjusting wooden partitions and fabric walls with built-in ropes, pulleys and cranks. Ms. Bonzanigo says, 'It’s designed to have a minimal impact on the environment around it, and the woods and fabrics used in its manufacture can vary depending on where it is built, for maximum sustainability. Explaining her design she says, 'Ojalá is a word that summarizes the concept of infinite possibilities, hopes related to emptiness and absence, intuition, a key of a door not yet open, a new field of existence, a telescope that brings together and moves horizons, a space of different possibilities and, therefore, a wish that comes true.'

Sustainability is evolving into an essential component of fashion and design industry due to environmental concerns. The Brooklyn Fashion + Design Accelerator (BF+DA), a Pratt Institute (US) initiative, is a hub of ethical fashion and design, providing resources to design entrepreneurs, creative technologists and professionals to turn ideas into businesses. Debera Johnson, founder and ED of BF+DA, also established the Center for Sustainable Design Strategies at Pratt Institute and has been integrating sustainability into art, design and architecture programs. She says, 'There are really three things that we're focused on doing. First - redefining the fashion industry around the environment and society...Second - we have production facilities open to designers. Our goal there is to be a local resource for sustainable production and to help educate designers about how to implement strategies around efficiencies and sustainable supply chain...The third and probably the newest part of what we're doing is becoming a research and design center for the integration of technology into smart garments and functional textiles - and, most importantly, with the idea of sustainability alongside it.' Regarding consumer perceptions, she says, 'Consumers need to decide whether they're more interested in saving pennies or saving the environment. Products that are quality are going to cost more. We just have to decide where we stand...At BF+DA, transparency is a big piece of how we do storytelling...' Regarding coming together of technology and sustainability, she says, 'The digitalization is one of them. I also think that biotech is creating really interesting materials in laboratories and not farms...Then you also have things like blockchain to help with traceability...And there's also nanofibers.'

Apparel production is generally linked to environmental issues like water and air pollution, alongwith the land, water and pesticide use related to growing natural fibers. But now research points at the source of another problem created by apparels made wholly or partially from synthetic textiles. Microfibers, a type of microplastic, are shed during normal use and laundering, and remain in the environment similar to plastic packaging that coats so many of the world's beaches, and they bond to chemical pollutants in the environment, such as DDT and PCB. Moreover, the textiles from which they are shed are often treated with waterproofing agents, stain- or fire-resistant chemicals or synthetic dyes that could be harmful to organisms that ingest them. Also, microfibers are being consumed alongwith food and drink. Research review (Microplastics in air: Are we breathing it in? - Johnny Gasperi, Stephanie L. Wright, Rachid Dris, France Collard, Corinne Mandin, Mohamed Guerrouache, Valérie Langlois, Frank J.Kelly, Bruno Tassin) published last year shows that microfibers suspended in air are possibly settling in human lungs. Research led by Richard C. Thompson from the University of Plymouth (UK) in 2004 (Lost at Sea: Where Is All the Plastic? - Richard C. Thompson, Ylva Olsen, Richard P. Mitchell, Anthony Davis, Steven J. Rowland, Anthony W. G. John, Daniel McGonigle, Andrea E. Russell) documented and quantified the occurrence of microplastics in the marine environment. Research by Mark Anthony Browne, one of Prof. Thompson's graduate student, published in 2011 (Accumulation of Microplastic on Shorelines Woldwide: Sources and Sinks - Mark Anthony Browne, Phillip Crump, Stewart J. Niven, Emma Teuten, Andrew Tonkin, Tamara Galloway, Richard Thompson) found - (1) Samples taken near wastewater disposal sites had 250% more microplastic than those from reference sites and the types of microplastic fibers found in those samples were mainly polymers often used in synthetic apparel, suggesting the fibers were eluding filters in wastewater treatment plants and being released with treated effluent (which is released into rivers, lakes or ocean water). (2) A single polyester fleece jacket could shed as many as 1900 of these tiny fibers each time it was washed. Another 2016 study by researchers from UC Santa Barbara in US (Microfiber Masses Recovered from Conventional Machine Washing of New or Aged Garments - Niko L. Hartline, Nicholas J. Bruce, Stephanie N. Karba, Elizabeth O. Ruff, Shreya U. Sonar, Patricia A. Holden) has shown far higher numbers - 250000 fibers. Rosalia Project, a nonprofit focused on ocean protection, led a study of microfiber pollution across an entire watershed (from the mouth of Hudson River all the way to where the river meets the Atlantic in Manhattan). Rachael Z. Miller, group's director, was surprised to find that, outside of samples taken near treatment plants, there was no statistically significant difference in the concentration fibers from the alpine region to the agricultural center of New York state to the high population areas of Manhattan and New Jersey. This suggested to her that fibers might be entering surface waters from the air and from septic system drainfields in rural areas without municipal sewage systems. According to Textile World, demand for polyester has grown faster than demand for wool, cotton and other fibers for at least 20 years. And by 2030 synthetics are expected to account for 75% of global apparel fiber production, or 107 million tons. All textiles, including carpeting and upholstery, produce microfibers. So do commercial fishing nets. But due to the frequency with which apparel is laundered and the increasing quantities of clothing being purchased throughout the world (thanks at least in part to the so-called fast fashion trend), apparel is the microfiber source on which researchers and policy-makers are focusing attention. Krystle Moody, a textile industry consultant, says, 'Outdoor gear is heavily reliant on synthetic textiles due to their performance profile (moisture wicking) and durability.' Jeffrey Silberman, professor and chairperson of textile development and marketing with the Fashion Institute of Technology at the State University of New York, says, 'Price is the big driver behind the use of synthetics in textiles. A poly-cotton blend is generally far cheaper than a cotton one, but doesn’t look or feel appreciably different to most consumers. The motivation is to get natural-like fibers and still be able to get a price point that people are willing to pay.' Katy Stevens, sustainability project manager for the outdoor gear industry consortium European Outdoor Group (EOG), says, 'Initial research suggested that recycled polyester might shed more microfibers. Are we doing the right thing by using recycled polyester that might shed more? It has added a whole other big question mark.' Other studies have found microfibers in effluent from wastewater plants (Wastewater Treatment Works (WwTW) as a Source of Microplastics in the Aquatic Environment - Fionn Murphy, Ciaran Ewins, Frederic Carbonnier, Brian Quinn), in the digestive tracts of market fish (Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress - Chelsea M. Rochman, Eunha Hoh, Tomofumi Kurobe, Swee J. Teh), throughout riversheds (Mountains to the sea: River study of plastic and non-plastic microfiber pollution in the northeast USA - Rachael Z. Miller, Andrew J. R. Watts, Brooke O. Winslow, Tamara S.Galloway, Abigail P. W. Barrows) and in air samples. Two separate studies released in March 2018 revealed that microfibers are found in bottled water sold all over the world. And a study published weeks later revealed that microplastic - chiefly microfibers - were present in 159 samples of tap water from around the word, a dozen brands of beer (made with Great Lakes water) as well as sea salt, also derived globally. Although most research has focused on synthetics textiles, but Abigail P. W. Barrows, an independent microplastics researcher who has conducted numerous studies on microfibers, says, 'Natural fibers such as cotton and wool, and semi-synthetics such as rayon should not be totally ignored. While they will degrade more quickly than, say, polyester, they may still be treated with chemicals of concern that can move up the food chain if the fibers are consumed before they degrade.' The study she led in 2018 (Marine environment microfiber contamination: Global patterns and the diversity of microparticle origins - Abigail P. W. Barrows, Sara E. Kathey, C. W. Petersen) found that in the surface water samples collected globally while 91% of the particles collected were microfibers, 12% of those were semi-synthetic and 31% were natural. Read on...

Australian fashion designer, Mark Liu, advises creative professionals to recognize the importance of studying STEM subjects (Science, Technology, Engineering and Maths) at school. He initiated 'Zero Waste Fashion Design' concept in which every piece of fabric is utilized in a fitting pattern. This process is contrary to the traditional linear pattern-making, which assumes a flat surface - with little account for the body's curves. Mr. Liu says, 'When you start pattern-making with zero waste, you really have to understand how it works to a really intricate level. Traditional techniques weren't really cutting it. I had to look at the underlying mathematics. And the more I looked, the more I found problems that mathematics had answers to but traditional pattern-making didn't.' He created 'Non-Euclidean' system of pattern-making that uses a technique called the 'Drape Measure' to record the curvature of surfaces as an angle measurement in order to create a more accurate design. Advocating STEM for creatives and designers, he also want 'A' for 'Arts' to be included to make it STEAM. Mr. Liu also supports and mentors students of International Grammar School (Sydney, Australia) emphasizing importance of maths. Ksenija Doic, design and technology teacher at school, says, 'They come into a creative subject thinking, 'Perhaps all I need is to have an idea, or be good with colours, or have an artistic side'. But what mathematics is useful for is the problem-solving part. The students who do maths find it easier to do the tasks at hand, because they have an innate knowledge of geometry, of working out curves and tangents.' Wynton Lambert, a student, says, 'Without some of the stuff I learned in maths, I wouldn't have been able to do the sleeve (of the shirt). It was very technical.' Mr. Liu considers STEAM to be the future and says, 'There’s this nice intersection between art and mathematics, and when they come together that's when really amazing things happen.' Read on...

Researchers at The University of British Columbia (Okanagan, Canada), Prof. Abbas Milani and graduate student Armin Rashidi, are working to solve the issue of wrinkling when it comes to making textile composites. Their research, 'A multi-step biaxial bias extension test for wrinkling/de-wrinkling characterization of woven fabrics: Towards optimum forming design guidelines', was recently published in Materials & Design Journal. According to Prof. Milani, wrinkling is one of the most common flaws in textile composites, which are widely used for prototypes, as well as mass production within prominent aerospace, energy, automotive and marine applications. Researchers have investigated several de-wrinkling methods and have discovered that they can improve their effectiveness by pulling the materials in two directions simultaneously during the manufacturing process. Mr. Rashidi says, 'The challenge was to avoid unwanted fibre misalignment or fibre rupture while capturing the out-of-plane wrinkles. Manufacturers who use these types of composites are looking for more information about their mechanical behaviour, especially under combined loading scenarios.' Prof. Milani, who is director of Materials and Manufacturing Research Institute at UBC Okanagan, says, 'Composite textiles are changing the way products are designed and built in advanced manufacturing sectors. As we continue to innovate in the area of composite textiles to include more polymer resin and fibre reinforcement options, this research will need to continue in order to provide the most up-to-date analysis for manufacturers in different application areas.'

EDIT (The Expo for Design, Innovation & Technology), the 10 day event held in Toronto (Canada) showcased art, installations and projects, focused on innovation and design to build a sustainable future for the world. It included talks from David Suzuki, Ian Campeau (A Tribe Called Red), among others. Here are 5 selected ideas and innovations - (1) Prosperity For All: Curated by Canadian designer Bruce Mau, the main exhibit juxtaposed Paolo Pellegrin's photos of devastation throughout world, with people and inventions that are helping to combat issues such as famine, refugee crisis, smog and more. It highlighted Smog Free Project (Dutch artist and innovator Daan Roosegaarde's smog free bike that works to purify the air around you while you ride), The Ocean Cleanup (Boyan Slat's creation that intend to remove 50% of the trash found in Great Pacific Garbage patch in just 5 years) and many more. (2) Art With Purpose: Dennis Kavelman, an artist and tech investor, collaborated with the Digital Futures team at OCAD University (Canada) to create a piece of work inspired by Andy Warhol. Expiry Dates works in two phases - It compiles answers from an online questionnaire, measuring your life expectancy against a myriad of points such as your fitness level, whether you smoke, if you're married and more. Then you sit for a self-portrait, which you attach to a QR Code with all your data. In a few minutes your heartbeat appears on the big screen, taken from a reading from your eye, and then your portrait appears along with your predicted date of expiry. Another piece of the installation, titled That's Not Very Many, uses a magnetized digital board to break down those days in months. (3) The New Housing: Living sustainably means looking at where we live and providing affordable housing for all. Exhibit included Mickey Mouse's Home of the Future that was a fully functional shipping container created by students at OCAD. The One House Many Nations home was created by grassroots organization Idle No More, that seeks to provide affordable housing based on traditional indigenous ideas, and consists of two modules that link together, one dubbed shelter and the other service, that can be pieced together based on the family or individual's needs as well as the landscape in which they live. (4) The Future Of Fashion: Fashion Takes Action's Design Forward award was given to a sustainable fashion label Peggy Sue Collection (founded by Peggy Sue Deaven-Smiltnieks), a line of eco-friendly cotton and denim. (5) Waste No More: Keeping in mind the concept of feeding many with minimal impact, Waterfarmers created an on-site aquaponics exhibit to show how fish waste can be used to fertilizer food. The idea is to utilize water that is housing fish to then fertilize plants, providing protein and vegetables in a sustainable manner. Read on...

Researchers from Hokkaido University (Japan) have created 'fiber-reinforced soft composites' or tough hydrogels combined with woven fiber fabric. The study, 'Energy-Dissipative Matrices Enable Synergistic Toughening in Fabric Reinforced Soft Composites' (Authors - Yiwan Huang, Daniel R. King, Taolin Sun, Takayuki Nonoyama, Takayuki Kurokawa, Tasuku Nakajima, Jian Ping Gong), was recently published in Advanced Functional Materials. Researchers combined hydrogels containing high levels of water with glass fiber fabric to create bendable, yet tough materials, employing the same method used to produce reinforced plastics. They found that a combination of polyampholyte (PA) gels, a type of hydrogel they developed earlier, and glass fiber fabric with a single fiber measuring around 10µm in diameter produced a strong, tensile material. The procedure to make the material is simply to immerse the fabric in PA precursor solutions for polymerization. The developed fiber-reinforced hydrogels are 25 times tougher than glass fiber fabric, and 100 times tougher than hydrogels. Moreover, the newly developed hydrogels are 5 times tougher compared to carbon steel. According to lead researcher, Prof. Jian Ping Gong, 'The fiber-reinforced hydrogels, with a 40 percent water level, are environmentally friendly. The material has multiple potential applications because of its reliability, durability and flexibility. For example, in addition to fashion and manufacturing uses, it could be used as artificial ligaments and tendons, which are subject to strong load-bearing tensions.' Read on...
