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

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.

Apple Wins Patent for Advanced Weaving Equipment

Apple was granted a “design patent” for Fabric. The U.S. Patent and Trademark Office officially granted Apple a patent for the specialized equipment that will make both regular and smart fabrics that Apple has other patent filings on. Apple envisions standard and smart fabrics will be incorporated into future products from Apple Watch bands to MacBooks, clothing, smartglasses and beyond.

The features of small-scale digital printing applied to the traditional dyeing process

Twine Solutions has created the world’s first standalone digital thread dyeing system which applies the features of small-scale digital printing to the traditional dyeing process. The plug and play machine dyes thread using digital printing technology and can produce any length and colour, whenever or wherever they are needed. The technology is based on waterless dyeing and will feature inbuilt colour software integrated with Coats ColourStitch.

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.
