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

Manufacturing inductive charging coils with textile embroidery technology

Contactless charging with induction coils is an important component of future plug-in hybrid and electric vehicles. It is well known that embroidery technology makes it possible to produce highly complex and sophisticated textile designs on a base fabric with several colours and threads. The researchers around Sathis Kumar Selvarayan, at the German Institutes for Textile and Fiber Research (DITF), have succeeded in optimizing the embroidery process so that it is suitable for the production of textile inductive charging coils.

Advanced textiles offer new forms for flexibility in building design

The Shed arts center recently opened in New York City. The need for flexibility has been transformed into the building’s own aesthetic. Ethylene tetrafluoroethylene (ETFE) pillows create a translucent telescopic outer shell that can be deployed to glide along rails to meet an adjoining plaza, effectively doubling the building’s footprint when it is needed for larger events. Power, lighting and theatrical rigging are all integrated into the soft structure held on a steel frame that acts as a skeleton.

Nonwovens: to be or not to be textiles?

Leaders from the global nonwoven associations held a joint strategy meeting at the IDEA 2019 Conference. The first step in advancing free and fair trade in nonwovens has been achieved with an updated and uniform nonwoven definition recently approved and published by the International Organization for Standardization (ISO) 9092:2019.
The new definition establishes nonwovens without reference to “textiles” as did the previous definition and introduces the concept of an engineered material. The new definition describes a nonwoven as an “engineered fibrous assembly, primarily planar, which has been given a designed level of structural integrity by physical and/or chemical means, excluding weaving, knitting or papermaking.”

An adaptable kinetic wall system awarded in the Textile Structures for New Buildings competition

Eight projects have been awarded in the Textile Structures for New Buildings competition at the Techtextil/Texprocess shows.
The first prize in Macro Architecture went to Rebecca Schedler from the Weißensee Kunsthochschule Berlin. She was awarded for her project Airdapt, in which she developed an adaptable kinetic wall system that offers the possibility of dividing large rooms into smaller working areas that can become more or less transparent and more or less sound-absorbing depending on requirements.
The Bubble won the first prize in the category macro architecture. Attracted by the unusual object, visitors are literally ‘sucked into’ the interior.

Intelligent yarns are attractive materials for future technologies

The applications of conductive threads are wide-ranging. They can transfer electricity and data and thus provide information about the stress on components, temperature or humidity. Embroidered on car seats as touch switches or incorporated into the sole of a shoe, these intelligent threads could replace raw material-intensive plastic switches and cables. This not only makes them significantly more environmentally friendly; they are also easy to process and more pleasant to grasp or wear.

Digital interlooping: 3D printing with SLS to create knitted structures

Mark Beecroft, a senior lecturer at the Manchester Metropolitan University School of Art, is exploring the use of 3D printing in industrial knitting in a process he calls 'digital interlooping'. Selective laser sintering (SLS) can create tubular knit-based structures using nylon (PA12) powder.
Previous 3D printed knitted structure research involved non-continuous printing methods and linked geometries. Beecroft’s work addresses this ‘gap’ in the literature. He believes his approach offers the opportunity for a new method of textile production.

Origami and high-performance textiles for smart human habitats

MoonMars project—architecture plans for smart human habitats and research stations on other planets. They are experimenting with origami and high-performance textiles to create habitats that are compact enough to transport and easy to deploy in extraterrestrial environments.
The MoonMars prototype entrance tunnel was deployed and tested to extreme conditions during the EuroMoonMars 2018 simulation at ESA–ESTEC. The origami structure was designed as a gateway and sub-system between the exo-habitat, airlock system and exo-laboratory.

A new digital thread dyeing system to dye exactly the amount you need

Twine’s system digitally dyes white thread from different manufacturers that can be used for a range of applications, such as apparel, activewear, shoes, accessories, home decor, vehicle upholstery and more. The SnapMatch application captures an image of a sample using a mobile device and Twine’s proprietary algorithms analyze the colour immediately. The user then sends the captured colour to the TS-1800 system for immediate thread dyeing in the desired colour.

Raised consciousness of consumers gives scope for yarn companies to develop their plans

Raised consciousness of consumers worldwide is feeding into priorities already established on sustainability and ultimate disposal of fashion garments, giving scope for yarn companies to develop their plans and spread the word. Pitti Immagine Filati continues to develop and encourage research into yarns and knitwear. Digital sampling is finally coming into its own, seen in action at Tollegno 1900 working with Shima Seiki machinery, Virtual Yarn Project, is ready as a regular tool with verisimilitude of printed fabrics giving the illusion of texture and 3D looks, enabling bespoke designs without vast expenditure. This is seen as a green measure, saving wasted fabric, dye and ultimately time and money.

A unique new silhouette for Museum of the Future in Dubai

In a region that is renowned for pushing the limits in architectural designs, The Museum of the Future in Dubai is one of the most complex composite projects to date, adding a unique new silhouette to the Dubai Downtown skyline. The project combines lightweight carbon and glass fibre prepregs, whose fire performance has been approved by the Dubai Civil Defence (DCD), with a stainless-steel outer cladding to produce the stunning outer skin of the torus shaped building.

Extreme sports require tough textiles

Today’s sport jumpers increasingly want parachutes that allow them to descend at a greater speed but still land where they’re supposed to. That’s accomplished by using smaller canopies as well as fabric that meets appropriate porosity expectations. Nylon may be the established standard for parachute fabric, but how that nylon is produced does change, for reasons of performance as well as aesthetics.
Ropes are certified and verified by third parties, with specific certification depending on the end use of the product. Climbing ropes are conformed to UIAA 101, the standard of the International Climbing and Mountaineering Federation, which specifies minimum performance properties.

Sensing molecular logic: first example of a molecular memory device

By shaking down electronics to the molecular level we would overcome the limitations of microlithography and other techniques and so extend Moore's Law well into the future. Moreover, molecular logic devices might open up new applications and new thinking in terms of what we might do with computation.
UK researchers have demonstrated the first example of a molecular memory device that follows-up storage with logic processing.

Researchers create carbon fibres with uniform porous structure

Liu is an assistant professor in the Department of Chemistry, in Virginia Tech’s College of Science. After tweaking a conventional method of chemically producing carbon fibres, now he has developed a process to synthesize porous carbon fibres with uniform size and spacing. He details this work in a recently published article in Science Advances.
It opens the way about designing materials for energy storage. Now one can also start to think about functionality: we not only use (carbon fibres) as a structural material but also a functional material.

A digitally knitted tapestry with technical functionality at Guggenheim Bilbao

Leading flat knitting machine manufacturer Stoll has helped create and manufacture the textile element of A Tent Without A Signal, a digitally knitted tapestry with technical functionality. Braided with metallic fibres, MOS’s tent doubles as so called a Faraday cage for the future, scrambling forthcoming 5G mobile signals. “It embodies a nomadic typology but denies its traditional formless slack in favor of a taught lofting between two archetypal symbols in plan — the cross and the circle — by means of a digitally flat-bed knitted futuristically fluorescent tapestry, completed in collaboration with ground-breaking textile technology maker, Stoll.”

Double-curved textile reinforced concrete elements

The CurveTex project objectives were the development of a drapable textile reinforcement for a concrete matrix and the production process (con-crete casting process) for double-curved textile reinforced concrete (TRC) elements with continuous fibre reinforcement.
The relevance of this research topic is not only limited to the construction sector, but also affects several textile-based sectors, such as the automotive industry, since the draping of conventional, two dimensional, textile semi-finished products in three-dimensional, near-net-shape preforms often leads to creases or draping errors.
