• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

Patients as well as air-condition and ventilator systems spread SARS-CoV-2 virus as aerosols which settle on surfaces and remain there infective for more than 72 hours. That‘s why the pandemic has triggered an intensive search for Personal Protective Equipment PPE whose surfaces have antiviral properties, e.g. are able to bind and inactivate adhering virus.

In this context the chemical stability of the materials being used for PPE, polypropylene PP and/or polyester PET, is a challenge. More precisely, the absence of so-called ‘functional groups‘, like -OH, -COO-, -NH3+ at the material‘s surface. These groups are the fundamental basis for surface chemistry – specifically for attaching antiviral compounds onto the surfaces of man-made fibers.

Antiviral surface modification with the basic amino acid Arginine Arg is a new approach to inactivate SARS-CoV-2. - bionic surfaces‘ - development was tested according to ISO 18184:2019 „Determination of antiviral activity of textile products“ at Institute for Virology and Immunology at University Wuerzburg, Germany. - The finding: „[Six hours] incubation on [Arginine] coated NW reduced viral infectivity by more than five orders of magnitude.“ In other words: An amount of, for example, 10.000.000 virus is reduced to 100 (by five orders of magnitude).

- bionic surfaces – has more than 30 years experience in wet-chemical surface modification of man-made polymers like PDMS, PP, PE, PTFE.

• Carbon fibers combined with injection molding replace conventional steel construction
• SGL Carbon supplies innovative carbon fiber profiles
• Serial use in a future high-volume model of BMW Group
• Construction method offers great potential for use in other automotive projects

Already in August, SGL Carbon received a multi-year order from Koller Kunststofftechnik GmbH for the production of novel carbon fiber profiles for serial use in windshields for a future high-volume model of BMW Group.

The profiles are particularly flexible fiber tows, pre-impregnated with thermoplastic resin in various dimensions. They will be compiled by SGL Carbon on the basis of its own 50k carbon fiber at its site in Innkreis, Austria, and subsequently processed by the injection molding experts at Koller to form a skeletal plastic component. The composite component will replace the previous steel-based windshield. Production of the carbon fiber profiles will start in the remainder of 2020 and will then be ramped up gradually over the next few years for the BMW Group model launch.

In the vehicle, the windshield is a connecting element between the roof frames and thus has an important stabilizing function. The carbon fiber profiles add the required stiffness and crash safety to the component. At the same time, they help to significantly reduce the weight of the roof and thus also support the driving dynamics. The injection molding process also enables particularly complex and material-efficient structures. In the BMW Group model, this innovative component concept will cut weight by 40 percent compared to conventional steel designs of the component while creating important space for cable ducts and sensors.

The production of the carbon fiber profiles themselves is also particularly geared to material and process efficiency in large-scale production. The profiles consist of several smaller fiber strands, the so-called rods, and are manufactured using the modern continuous pultrusion process. During product and process development it was one key objective to ensure that material loss during production is almost completely avoided.

"At SGL Carbon, we have been working on the development of thermoplastic carbon fiber profiles for use in injection molding for some time already. This development work is now beginning to pay off. Due to the many advantages and competitive costs, we see a great potential for the technology to be used in other automotive projects too," explains Sebastian Grasser, Head of the Automotive Segment in the Business Unit Composites - Fibers & Materials at SGL Carbon.

"Innovative lightweight construction with hybrid designs has developed into a strategically conclusive concept for Koller Group's OEM customers," confirms Max Koller, CEO of Koller Group. "SGL Carbon's high level of material expertise, combined with the process know-how of KOLLER Kunststofftechnik and KOLLER Formenbau, create the basis for a promising future in innovative lightweight construction technologies. With this order, the BMW Group has confirmed its confidence in the successful cooperation between SGL and Koller; we are particularly pleased about this", said Max Koller.
 
The Koller Group is a globally operating technology company with plants in Europe and China, as well as NAFTA. The Koller Group develops and manufactures lightweight construction, tools and serial components, primarily for the automotive industry.

• Composite textiles for modern mobility
• Extremely lightweight, high tensile components by vombaur

In the snow, on a plane, in an electric vehicle or on a bicycle: no matter where and how we are on the road – composite textiles by vombaur ensure that we make good progress. With materials that are both extremely light and extremely reliable.

Lightweight components for modern mobility
Modern mobility relies on high-tech lightweight components Narrow textiles by vombaur are woven from high-performance fibres. On looms that are specially made for particularly demanding composite textiles: the textile company uses special machines to produce high-tech woven tapes with closed selvedges and elasticated UD tubulars that retain their 0° orientation over the entire length of the component – regardless of the diameter. Since they do not exhibit undesired break points caused by seams or welding, they not only have a particularly high bursting strength, they are also extremely reliable and durable.

Challenging applications
"From snowboards to aerospace – the applications for our composite textiles are demanding; the mechanical, chemical and thermal requirements are extreme," explains COO Christoph Schliefer. "As a development partner, we at vombaur are therefore often involved in product development at an early stage. We specify our woven tapes and tubulars individually for each project to suit the specific task at hand."

High quality raw materials, wide variety of geometries
The variety of shapes is virtually unlimited. vombaur manufactures 3D fabrics for composites in individual special shapes from carbon, aramid, glass or hybrids. Curves, edges, tubulars, spiral fabrics – the shape of the 3D fabrics, like the material itself, depends entirely on the task at hand. Powder or non-woven coatings create additional important properties.

Pioneering tech tex
"Developments in the field of modern mobility are happening at a rapid pace," emphasizes Schliefer. "With our composite textiles for extremely lightweight and high tenacity components, we at vombaur are also pushing these developments forward."

“When it comes to working on new developments, we always start from new ideas and the constant research that starts from a concept that becomes reality, by increasingly raising the bar of sustainability” said Alice Tonello, R&D and Marketing Director of Tonello. “The research for technologies and solutions have always been part of our DNA, is a daily commitment to the environment, the market, our people and all human beings with their needs.  Based on this vision, two revolutionary patent-pending process, are born, Wake and OBleach, that allow to create incredible and totally responsible effects on garments” continued Alice Tonello.

This is how The Laundry (R)Evolution was born: a radically new conception thought to simplify and optimize the entire garment finishing process.

It involves only 2 technologies in the entire finishing cycle, reducing waste and optimizing resources: LaserBlaze, and The All-in-One-System. Metro is used, a software that processes real data, in real time to check all laundry consumption, optimizing processing times and improving performance.

The All-in-One System performs all washing operations by integrating 4 sustainable technologies into a single machine: ECOfree 2, which uses ozone in both the water and air; NoStone® for authentic and pumice-free stone-wash effects; UP, for washing processes with at least 50% less water; Core, a nebulizing system improving performance and reducing water consumption.

In terms of effects, the latest results of the Laundry (R)evolution are OBleach and Wake.

OBleach is the new Tonello patent-pending process which, by using only ozone, “returns to the future” with an authentic, sustainable and cool Bleach.

Wake is the first totally natural dyeing system. In fact, it uses only plants and vegetable waste, organic items like flowers, berries and roots left to dry and infuse, without harmful chemicals additives.

Tonello will be live during DenimsandJeans Virtual Show on October 14th and 15th.

Elastics for power support in medicine and the work environment
People who do physically hard work are relieved; people who are learning how to walk again after an accident or a stroke receive support; people with a handicap gain greater mobility – exoskeletons offer valuable support in many areas. An important component for "power suits": elastics by JUMBO-Textil.

Support construction with and without drive
An exoskeleton is a kind of robot that you wear: a construction of mainly textile components that is slipped over the body and strapped on. Integrated sensors register the body movements. These impulses are converted into electrically driven movements of the exoskeleton, which support or amplify the human movement. In addition, exoskeletons without drive are also being developed: these designs aim to transfer the weight of heavy tools or loads directly into the ground.

Tough requirements, individual solutions
Since the skeletons are worn on the body, the textiles and textile components used here need to be skin-friendly and as light as possible. The body's own temperature regulating systems must not be impeded. The contact surfaces must not create pressure points. And the exoskeletons must be individually adaptable to the user's body measurements.

High-tech elastics by JUMBO-Textil offer solutions for the development of exoskeletons – in terms of functionality, safety and wearing comfort: they hold, clamp, close and secure. They relieve and cushion movements and force impact. They illuminate and forward signals. The breathable narrow textiles stretch in both directions as required. They fit snugly on the body and follow every movement. Full-surface hook-and-loop-ready elastic tapes offer a simple, secure and individually adjustable fastening option. JUMBO-Textil consistently uses components made of plastic or light metal for textile components as fastening solutions. As a solution partner for demanding tasks – e.g., in occupational safety – JUMBO-Textil also developes cooled or heated textiles in collaboration with their customers. Also possible: the development of self-luminous narrow textiles – for additional safety.
