From the Sector

Hypetex®, a leader in colouring carbon fibre materials, is delighted to announce that its Hypetex® Kromaskin™ field hockey stick for adidas has been selected as a finalist for the 2022 JEC Innovation Awards.

Hypetex® was commissioned by adidas to develop a market leading hockey stick differentiated from existing equipment not just by its unique pigmented carbon fibre finish, but also by its game changing hitting power and consistency. The patented range of Kromaskin™ sticks, created with support from project partners Textreme® and Marque Makers, was found to outperform competitors in a benchmark study against eight other premium hockey sticks carried out by Loughborough’s Sports Technology Institute (STI).

Hypetex® lead the design, engineering, materials, and production process development for the adidas field hockey stick project. By incorporating the stick’s finish colour within the outermost carbon fibre layer, the stick mould could be adjusted outwards, placing the highly structural spread tow materials right at the outer extremities of the mould cavity, increasing mechanical performance and maximising the structural benefits of the composite materials used.

Whilst the Kromaskin™ surface provides a stunning depth of colour with minimal finishing required after demoulding, the Hypetex® technology, including an epoxy based expanding microsphere system used in the core, delivers significant performance gains on the hockey pitch. In tests at the STI, adidas Kromaskin™ sticks had up to 16% higher coefficient of restitution (COR), meaning they will return more energy and the ball will travel faster. In addition, through the production led design and materials used, the variation in COR was 70% less than the other sticks on test, a significant reduction in the production inconsistencies common with the manufacturing of performance sporting goods.

Strict protective measures will make the industry meeting possible at the International Conference on Cellulose Fibres in Cologne on February 2 and 3, 2022. The latest innovations will be shocased: from hygiene and textiles to non-wovens and carbon fibre alternatives to lightweight construction applications. Online participation is also possible.

Cellulose fibres show an increasingly expanding wide range of applications, while at the same time markets are driven by technological developments and political framework conditions, especially bans and restrictions on plastics and increasing sustainability requirements. The conference provides rich information on opportunities for cellulose fibres through policy assessment, a session on sustainability, recycling and alternative feedstocks as well as latest development in pulp, cellulose fibres and yarns. This includes application such as non-wovens, packaging and composites.

Live at the conference, host nova-Institute and sponsor GIG Karasek GmbH will grand the “Cellulose Fibre Innovation of the Year” award to one of six highly interesting products, ranging from cellulose made of orange and wood pulp to a novel technology for cellulose fibre production. The presentations, election of the winner by the conference audience and the award ceremony will take place on the first day of the conference.

The conference sessions reflect the current topics of industry and research. “Strategies and Market Trends” provides an overview of the rapid development of cellulose fibres and their technological progress across the fibre market. An analysis of the key cost components of these fibres to benchmark against current cost levels will highlight future opportunities and challenges for novel textile fibres. The session will conclude with an overview of the industry's recent strategies to defossilize the fibre market.

The session “New Opportunities for Cellulose Fibres in Replacing Plastics”, focusses on questions such as: “What impact does the ban on plastics in single-use products have on the industry?” and “What are the latest regulatory issues and policy opportunities for cellulose fibres?”. This part of the conference presents new opportunities for the replacement of fossil-based insulating materials with cellulose-based technologies suitable for use in a variety of applications, from aerospace to mobility and construction.

The year 2021 is expected to end on an extremely positive note for the Swiss Group, with an organic turnover record (significantly higher than pre-pandemic levels) and an acceleration of the product range completion strategy: after the addition of Amom, in June, Riri is proud to share the closing of the acquisition and integration into the Group of DMC, a company specialized in the metal components sector for haute couture, more specifically leatherwear. This is another step towards creating a single hub dedicated to luxury accessories, whose goal is to develop a balanced portfolio including zips, buttons, metal hardware, and fashion jewels.

DMC, established in 1976 in Scarperia e San Piero a Sieve, near Florence, has a consolidated experience with major luxury brands and a strategic position, being located close to the Tuscan leatherwear district. Originally a family-run business, today it is a company which combines highly skilled Italian artisan tradition, which has a strong connection in the region, with the use of cutting-edge technologies. Its comprehensive vertical integration system allows for in-house management of all production process phases.

“The addition of DMC to the family” – explains Renato Usoni, CEO of the Riri Group – “is not just a bonus for our offer in terms of product range. It means also a fundamental milestone in the creation strategy of a fully integrated business model”. As a matter of fact, the operation is a further improvement in the Group’s designing potential, increasingly able to provide tailor-made accessories, as requested by each client, achieving very high levels of customization while keeping up massive investments in new technologies, organization systems and sustainability projects with a cross-cutting impact.

“Our Group” – Usoni adds – “is, to all intents and purposes, a leader in terms of innovation, thanks to its state-of-the-art plants, which are located in seven production factories, and thanks to its constant search on emerging technologies and materials”. More specifically, DMC’s proposal – in line with Riri’s – is increasingly focused on the use of sustainable products and on processes with a low environmental impact.

Furthermore, the new company in the Group is committed to integrating the economic development of its business with the ensuing social accountability. Evidence of this attention is shown by its having been awarded the certifications ISO 9001, due to the quality of its processes, products and services, and SA 8000, for its ethical management of human resource. Moreover, every year DMC produces a social report which, in line with what have always been distinctive values of Riri, bears witness to its intent of communicating its achievements clearly and transparently.

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

Examples of this include the development of 3D braided ceramic matrix composite components for aircraft engines, which were researched together with partners in a Horizon 2020 project (EU project AllOxITD). The ongoing Chrysomallos research project as another example, funded under the national aeronautics research programme in Germany, aims to develop a completely new and sustainable high-performance insulator for aircraft cabins based on aerogels. These have a significantly lower weight than the glass fibre mats used up to now, while providing the same insulation performance, and solve the problem of the previously high manufacturing costs of aerogels. The aim of the project is to develop an insulation material with reduced density (reduction of more than 20 percent). To this end, a new type of insulation material based on aerogel is to be developed. The basis is an aerogel fleece (0.06 W/mK at 28 kg/m³), which has already been developed as part of a dissertation at the Institut für Textiltechnik of RWTH Aachen University (Mroszczok, J.: 2019).

The aviation industry is one of the fastest growing industries in the world. Due to this fact and its importance for society and the global economy, it needs to make special efforts towards sustainability. The ISSA, an international multi-disciplinary symposium, aims to address current issues in aviation such as improving aircraft fuel efficiency, promoting the use of biofuels, minimising environmental impact, mitigating greenhouse gas emissions and reducing engine and aircraft noise. ^

Through the award, SARES honours scientists and researchers whose work on sustainable aviation issues has made an important contribution at the international level. The selection is based on the scientific publications of the applicant or nominee, the h-index, i.e. the key figure for the worldwide perception of a scientist in professional circles, the project topics and the project results.

Kai-Chieh Kuo, PhD student at the Institut für Textiltechnik (ITA) of RWTH Aachen University, was awarded the German Textile Mechanical Engineering 2021 Best Master's Thesis Award for his master's thesis entitled "Modification of the tube weaving process of fine yarns for the production of woven ultra-low profile stent grafts". The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (≤20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.

In the Canopy’s 2021 Hot Button Ranking, Kelheim Fibres once again occupies a leading position: With a increase of 2.5 points in the evaluation, the Bavarian viscose speciality fibre manufacturer tied for third place out of around 40 viscose fibre manufacturers worldwide and a dark green/green shirt for the second year running.
