The ITA Group, consisting of the Institute for Textile Technology of RWTH Aachen University (ITA), their research and development service provider ITA Technologietransfer GmbH (ITA GmbH) are proud to announce their new strategic positioning: in order to better respond to actual industrial demands and needs, ITA decided to install a partnership model as of January, 25 2022.

The ITA Group comprises the ITA of RWTH Aachen University, a leading research and qualification research institute with 400 employees in the areas of fibre-based high-performance materials, textile semi-finished products and their manufacturing processes and the ITA Technologietransfer GmbH, the partner of the industry in R&D, providing technology and knowledge transfer, as well as offering comprehensive solutions along the entire textile value chain.

Prof. Dr. Thomas Gries, Director of ITA, explains the new partnership model:” The impact of the Covid-19-crisis has shown once more the importance of long-term trustworthy business relationships. Therefore, we are establishing our new partnership model where we will even more closely cooperate with our actual and future industrial partners, providing them with the latest technologies and innovations from R&D side. We will initiate networking and workgroup meetings, offer access to ITA´s large machine parks and labs, carry out joint partner projects and commonly organized publicly-funded projects as well as training for partner´s employees and HR opportunities.”

Dr. Christoph Greb, Scientific Director of ITA: “We are very happy to initiate this new partnership model where science, research and industry are working shoulder to shoulder in pre-competitive projects on our future projects along the entire value-chain from the fibre to the final component in order to close a missing gap and form innovative paths forward in various industrial fields.”

During an initial session of three Innovation days in hybrid format, ITA successfully introduced in September 2021 the first industrial partner projects which will be carried out, among them “Recycling of composite battery cases”, “Recycling of composite pressure vessels”, “Natural Fibre Composites”, “Textile Structures with focus on biaxial Warp-Knitted Structures”, “Factory of the Future”, “Tapes and Hybrid Yarns”.

The next opportunity to meet with ITA is at JEC DACH in Frankfurt (November 23 and 24 2021).

• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer enterprise development teams and individually for the respective projects." This is how novel and unique lightweight components made of high-performance textiles are created for visionary projects.

Freudenberg Performance Materials (Freudenberg) offers a range of efficient interlinings, tapes and thermal insulation materials for workwear and protective clothing. The materials not only withstand diverse kinds of strain they are exposed to in everyday work and washing procedures but also offer great comfort.

Innovative materials and manufacturing technology
The nonwoven and woven interlinings and tapes stand out due to a number of features, such as increased stability, elasticity, abrasion resistance and wind-blocking properties. Thanks to the sophisticated adhesive technology used by the manufacturer of technical textiles, some products are especially resistant and durable.

Highly flexible and resilient interlinings as well as Freudenberg comfortemp® thermal insulation materials are used for protective clothing, and they do not only protect the wearer from danger but also ensure the wearer’s comfort in any kind of weather. Furthermore, hem and edge stabilisation tapes ensure optimal fit and reflective tapes provide additional safety.  

Active contribution to sustainability
Many products of the Freudenberg Workwear Range consist of a high percentage of recycled polyester coming from post-consumer PET bottles.

• Riri’s SS 2022 collection explores the mind of the future.
• Bright colors, vintage themes as well as timeless designs and attention to detail, combined with concepts that highlight history and processes.

Riri Group’s gaze looks to the future once more, offering a line of accessories where creativity meets cutting-edge technology. This is the scenario spawning the new SS 2022 collection; a range of innovative proposals each representing a different emotional response to the pandemic, an attempt to interpret the emotions, needs and desires of consumers in the coming years.

The Italian-Swiss group, that for almost a century has committed to creating zips and buttons for the world’s most important fashion brands, doubles down on its forward-looking vision. The result is SS 2022 collection, featuring three different aspirational paths to read into the emerging feelings of the “new normal” that is our time and that may characterize the near future.

REJOICE
Inspired by sensations of euphoria and breaking free from melancholy through evasion and exuberance, Rejoice is the line that sees in positivity and joy of re-living the answer to the months of pandemic and negativity. The optimism that is to come takes the form of a creative and extrovert style, even when it comes to accessories. The inspiration, a triumph of bright colors and timeless styles, comes straight from the streets of Boca, one of Buenos Aires’ most popular neighborhoods thanks to its combination of colors and creative scene. Thus, the Eloxal rio zip is presented once again: with its aluminum chain and colored teeth, matched with a multi-color effect puller. In the range, we can also find the Nylon zip, featuring changing colors matched with buttons that echo their color variations, or the Filmetal 14 zip, big and with eye-catching writings, embossed on the tape.

REBIRTH
Going back to the future, in a more respectful and responsible way, through a rebirth that comes to be thanks to a closer relationship with nature. In this line history and processes through which the product is made are pivotal to tell a new way to approach the world. The range comprises zips and buttons developed with natural material and processed manually. A return to the basics as well as the constant research to reduce resources use respecting the planet are foundation of this line. Part of the Rebirth line are the copper jeans buttons, with a special water-based paint finishing, transparent and protective, or the hemp-derived bio-plastic eyelets, as well as the galalite buttons, a particular bio-degradable plastic, derived from processed milk proteins. A major innovation are our tapes entirely made of recycled polyester, evidence of the commitment by Riri Group to reuse resources.

TIMELESS
Timeless elegance, essential luxury mixed with the highest quality standards for top-of-therange products. Design, materials and colors featuring in this line break away from seasonal trends to become timeless must-haves, essential yet elegant. Every piece is cared for in every detail, created specifically to leave a lasting mark. Buttons, chains and pullers are either made of gold and silver, or they feature the clean and elegant tone of stainless steel. Among the zips, stand out Metal and Simmetrical with luxury finishings, whilst tapes are made with refined materials, such as leather and satin. Essential yet researched, this range comes with square and oval cuts, with geometry being functional and complementary to a timeless elegance.

• 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.

With their recently installed high-temperature unidirectional tape line, Japan-based composites manufacturer MaruHachi enables new opportunities for high-end applications in demanding market segments like aerospace, automotive or others outperforming traditional materials based on PP and PA which are already widely available.

In the first phase, MaruHachi will produce up to 40 tons/year and focuses now specifically on high-temperature thermoplastic uni-directional (UD) tapes and multi-layer sheet laminates. The material is based on high-performance fibers like carbon, aramid, glass or natural fibers and the matrix can be high-performance polymers like PPS, PEEK or other higher temperature polymers, which are much tougher than epoxies and easy to recycle. With a width of 500 mm, a specific weight from 60 to 350 g/m2, depending on the chosen material, the lines can operate under temperatures up to 420 degrees Celsius. Working under these extremely high temperatures allows for better material properties of the final application, higher performance, increased resistance and integrated high-performance functionalities e.g. by overmoulding.

Since 2017, MaruHachi Group is active in the European market in cooperation with Dr. Michael Effing,the CEO of AMAC GmbH, who advises and supports the company strategically. The established, family-owned MaruHachi Group has a strong history in automotive and medical textiles and has been active in the innovative composites market for more than 15 years.

Toshi Sugahara, CEO of MaruHachi: “For many years, we have already been cooperating with domestic and international partners on high-demand applications and therefore, MaruHachi decided now to invest over 1 million EUR in this new line in phase 1, including a funding participation from the Japanese government NEDO. New developments in phase 2 will be be undertaken by end of 2021 on the downstream technologies like the automated preforming and consolidation. With our new products, we want to contribute to significant weight reductions of the final products, thus improve energy efficiency while offering a cost-efficient and high-quality solution.”

Dr. Effing, CEO of AMAC GmbH confirms: „The focus on the niche of high-temperature products based on PPS and PEEK allows MaruHachi on very demanding high-end applications such as structural frames on space and aircrafts, aircraft seats or engine components etc. The tapes are fully recyclable and can be processed e.g. with high-speed with laser-based tape placement machines and robots.”

• 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."

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.

At this year’s trade fair „SIMAC Tanning Tech“, PFAFF Industrial, together with DÜRKOPP ADLER and the regional agency DAP ITALIA, will present the latest solutions for shoe and leather processing. The fair will take place in Milan from 19th to 21st of February 2020. The joint booth is located in Hall 14, No. C09.

PFAFF News and Highlights:

PFAFF 3806
New integrated workplace for closing rub-down seams, such as heel-, front- and side seams on street shoes, slippers and leg boots. The PFAFF 3806 is equipped with two-thread chainstitch high-speed seamer head PFAFF 5487 with drop feed and variable top feed, high lift and adjustable top feed pressure, which ensures consistently high quality. Reinforcing tapes, which may be applied from top impart greater durability to the seams and prevent fine leathers from being pulled out of shape. Automatic control sequences (via parameter or photocell) reduce the manual handling and increase the process reliability and output.

PFAFF 1591
On the fair PFAFF INDUSTRIAL will show its electronic single-needle shoe post-bed machine with touch-control panel, new thread trimmer for short thread ends (< 5 mm) and new programmable thread tension. The key benefit of “programmable thread tension” is that suitable thread tensions can be applied for different material thicknesses and/or for different seam sequences (as these can be programmed on electronic machines). The tensions can be accessed and/or set via a knee switch or stitch counting. Manual setting of the thread tension, as is common with current shoe machines, is no longer necessary with the programmed thread tension.

PFAFF 8303i
The ot-air taping machine for welding continuous seams on water-resistant, waterproof and breathable materials will be exhibited as “shoe version” with very small/slim post from back. Effortlessly shoe uppers with small radii can be taped. The slim post and the differential feed (via two separate drive motors for the top and bottom feed roller) ensures absolute neat seams and a requested fullness und shaped parts.
 

• Ice, style and performance

These are the keywords which describe the new eclectic creations by the Riri Group for the Fall Winter season 2020-2021: a journey through the winter, its atmosphere and its colours Mendrisio, September 2019 - Première Vision Paris (17 - 19 September) will set the stage for the new proposals for the Fall Winter 2020-21 collection by the Riri Group, a leading brand in the zip and button manufacturing sector for high couture and outdoor apparel. A preview of the new collection by the Swiss group will take place at Munich Fabric Start (3 – 5 September).

COLOURS, MATERIALS AND TEXTURES

Winter landscapes and polar tones have inspired the colours of this new collection: nuances of grey, azure and white remind us of the typical tones of ice; also dominant is the presence of blue, intense and rich in contrast thanks to the attractive green inserts; black interventions are then harmoniously inserted as part of the colour palette, creating an appealing interplay of colour references. Tapes, pullers and chains provide new pleasant tactile sensations and unexpected visual inputs, through the search for always new processing methods the iceberg effect reproduced with a laser system, the texture reminding us of snake skin, from marble effect to horn processing, and freehand diamond turning, as well as the three-dimensional drop varnishing and the stylish mother-of-pearl effect.

NOVELTIES

The guiding thread for the new “Winterstorm” collection is the use of nuanced colours and ‘ice-like’ effects, reminding us of winter landscape and climates, as in the new Decor Cristal zip with transparent chain or in the Aquatyre zip, available also in a new luminescent version. Among the new creations, the Metal 3H zip stands out: the smallest and most innovative in the collection, lightweight and with a streamlined design. The provocations for this fall-winter have reached extreme levels, with a zip made of synthetic fur and incorporated buttons, whose cover can be removed and then reapplied, to face polar temperatures with a touch of glamour. Alongside the most fashionable novelties, the research by the Riri group does not cease to surprise in the outdoor sector also as regards buttons. This is confirmed by Rislide, the snap closure with a nylon body and Zama button. The innovative b-lock pressure button – with high lateral hold – has been restyled with a silicone shaped head in three colours. As part of a collection characterised by style and performance elements, it is definitely worth mentioning Zero, also in its invisible version: this button – thanks to its elegant design, combines practicality and style without compromising on performance.
