The gossip of “texturgie”: creating new sensitive matters by combining textile textures and high technologies

New knitting machines allow full integration of technology into the garment

The knitting industry has come a long way in the last four years with shoes and wearables leading the charge. Different knitting machine configurations are designed for flat knitting, circular knitting for body-mapped garments, knitted shoes and warp knitting. Some of them are able to produce hybrid knit-weave fabrics that allow insertion of technical yarns.
Elimination of sewing allows high potential for on-demand knitting. The seam-free nature also ensures continuity of the fabric, allowing conductive fibers to wrap around the entire body without interruption for applications in smart garments and wearable technology.

From pulp and paper industry to cellulose-based textile fibre

The traditional textile industry uses thousands of chemicals in various processes of manufacture, including dyeing and printing. Inherent dyeing in the Spinnova process means that the cellulosic fibre mass is dyed before extruding into filament. This avoids the excess use of water, energy, heavy metals and other harmful substances that go into dyeing fibre, and subsequent yarn and fabric processes.
Spinnova’s innovation originates from the pulp and paper industry and develops ecological breakthrough technology for manufacturing cellulose-based textile fibre.

A new function of architecture for a sustainable future

Architects are fond of describing their buildings in the metaphoric terms of the human body. The supporting structure is often referred to as the skeleton that holds it up. The most exciting innovations and serious attention in the construction industries for the past 10 to 20 years has focused on the skin of buildings (the enclosure that protects the insides).
Fabric facades are a vital part of this growth and perhaps the fastest growing segment of fabric architecture production where innovations are most likely to be found. Architect Nicholas Goldsmith, senior principal of FTL Design Engineering Studio, New York, N.Y., affirms this trend in his new book, Mass to Membrane.

A new biosensor to detect the COVID-19 virus

A team of researchers from Swiss Empa, ETH Zurich and Zurich University Hospital has succeeded in developing a novel sensor for detecting the new coronavirus. In future it could be used to measure the concentration of the virus in the environment – for example in places where there are many people or in hospital ventilation systems.
Jing Wang and his team have developed an alternative test method in the form of an optical biosensor. The sensor combines two different effects to detect the virus safely and reliably: an optical and a thermal one.

EDANA Joins Circular Plastic Alliance

EDANA, the association representing the nonwovens and related european industries, has joined the Circular Plastics Alliance, endorsing a vision to deliver on the circular economy for plastics. By 2025 at least 10 million tons of recycled plastics should find their way into products and packaging in Europe each year. This consortium is supported by the European Commission in the context of the European Plastics Strategy and its concrete actions are structured around five deliverables on design, collection and sorting, recycled content R&D and investments and monitoring.
In 2018, EDANA issued a pledge to significantly increase the use of recycled PET (rPET) in nonwovens.

Fashion brands are being urged to dramatically cut their use of virgin raw materials

The call comes in a new report, entitled the Earth Logic Action Plan, which was commissioned by the JJ Charitable Trust and written by a group of academics, business leaders and analysts.
It urges businesses across the global fashion sector to “radically transform” their models, to put nature ahead of short-term financial gain, by reducing their use of virgin resources by 75 per cent by 2030.

Copper nanoparticles being tested for anti-viral textiles

By embedding nano-copper into polymer fibres, such as nylon, via a melt extrusion process, it was found that the antimicrobial effect lasted longer than other similar antimicrobial fabrics on the market, which tended to be surface-coated and therefore lose functionality with each wash.
Pioneering UK manufacturer, Promethean Particles, reports it is collaborating with textile companies and leading research facilities to explore the anti-viral effects of its novel copper nanoparticles designed for use in fabrics and Personal Protective Equipment (PPE) for the healthcare sector.

Temperature-responsive garments that maintain comfort wherever they’re worn

It can be uncomfortable to wear a heavy coat on a day that doesn't need it, as well as a light jacket on a day where more warmth is needed. Skyscrape uses an innovative new type of yarn that's structured to have an exaggerated response to heat variation. As temperature changes, the active yarns in the fabric expand and contract, causing it to bend, increasing or decreasing the thickness of the fabric and its insulative properties. The fabric itself acts as a thermometer.
Creating a textile - that naturally changes shape without wires or sensors - required years of laboratory work, designing machines (weavers, knitters) and developing processes.

Textile microfibres shed fast in everyday wear

New research on the extent of textile microfibre pollution in the environment suggests that garments emit substantially more microfibres when worn than they do when laundered. Whilst as many as 4,000 fibres per gram of fabric were shed in a single laundering, 400 fibres per gram of fabric were emitted in just 20 minutes of ‘normal activity’, suggesting the long-term implications of simply wearing garments could have a far more significant effect on the environment.

The skin: a gateway to the human body

The skin is the largest organ in the human body and one of the primary ways in which humans interact with the world around them. Likewise, many of the ways in which we impact the human body--from the application of heat to soothe sore muscles, to the squeeze of a hand to let someone know you care, are mediated through the skin. Myant Inc., pioneers in textile computing, exhibited at CES 2020 in Las Vegas a full-body interface implemented through textile that creates new ways to holistically understand and communicate with the human body.

How synthetic biology is dyeing the future of fashion

With 20% of the earth’s water pollution caused by textile processing, and 1,800 gallons of water required to make a single pair of blue jeans, companies like Tinctorium, PILI, and Colorifix are turning to synthetic biology for solutions - making bio-based, sustainable alternatives the new vogue in fashion.
Normally, [depositing a dye onto fabric] is done with chemicals or biologically-produced compounds, but without a biological agent. Colorifix lab is using the cells themselves to both produce and deposit the pigment into the fiber, so biology is used for the entire process. It allows to save on water and energy and remove chemicals.

Dying textiles deep colours without water

The textile industry uses on average about 100-150 litres of water to process 1 kilogramme of textile material. Some 28 billion kilos of textiles are dyed annually. DyeCoo, based in Weesp near Amsterdam, is a leader in water-free and chemical-free textile dyeing. Its technology uses (reclaimed) CO2 as the dyeing medium in a closed-loop process. When heated and pressurised, CO2 becomes supercritical, a phase between a liquid and a gas. In this state CO2 has a very high solvent power, meaning the dye can dissolve easily and deeply into fibres, creating a vibrant colour.

There is a high percentage of natural fibres in our water

Researchers from the University of Nottingham have found a much higher percentage of ‘natural’ fibres than microplastic fibres in freshwater and atmospheric samples in the UK. The potential role of natural textile fibres like cotton and wool, as an environmental pollutant, has been speculated on by some environmental scientists, but there has been a general consensus that their biodegradability reduces their environmental threat (in comparison to that of plastic).
But are natural fibres really better for the environment than microplastic fibres?

Selecting the ideal fiber and weave for medical device textiles

Weaving biomedical textile structures, such as straight, tapered, flared, and bifurcated vascular grafts, is an art requiring precision and unwavering attention to detail. The structures are made by weaving, knitting, and braiding, in which two sets of fibers or yarns are tightly interlaced.
Dimensional stability enables structures to retain their shapes for longer periods of time, and low elongation in a woven structure ensures the device serves its intended purpose. Appropriately selecting a biomedical fiber for a given application depends on the performance required of the biomedical device in question.
