From the Sector

LEIBINGER, ein weltweit tätiges deutsches Familienunternehmen für Kennzeichnungssystemen, hat sein Top-Management erweitert und Christophe Lopez zum Chief Commercial Officer ernannt.

Christophe Lopez bringt mehr als 15 Jahre Erfahrung in der Kennzeichnungsindustrie mit, in denen er zahlreiche Führungspositionen mit Vertriebs- und Marketingverantwortung bekleidete. In der Position als Chief Commercial Officer bei LEIBINGER wird Lopez die kommerzielle Entwicklung des Unternehmens verantworten und den Ausbau der globalen Vertriebs- und Marketingaktivitäten vorantreiben.

Lopez hat einen Abschluss der Ingenieurshochschule INSA Rennes und einen Executive MBA mit höchster Auszeichnung der Management-Universität HEC Paris. Er war langjähriges Mitglied des Executive Committee beim Wettbewerber Markem-Imaje, wo er diverse globale Führungspositionen, unter anderem mit globaler Gesamtverantwortung für den Vertrieb und das Marketing, übernahm und zuletzt als Président des Hauptstandorts in Frankreich über 600 Mitarbeiter führte. Zudem baute er das E-Commerce-Geschäft erfolgreich auf einen Umsatz von über 100 Millionen US-Dollar aus.

Können gebrauchte Textilien recycelt werden? In den meisten Fällen enden sie eher als Putztücher oder Dämmmaterial (Downcycling) statt als neue Kleidung oder Bettwäsche (Recycling). Für Faser-zu-Faser-Recycling muss noch viel erforscht werden. Genau dieser Aufgabe stellen sich nun die Hochschule Niederrhein (HSNR) und weitere Kooperationspartner im Förder-Projekt „KICKup“ (KI-gestützte, chemische Cellulose-Kreisläufe). Das hochschuleigene Forschungsinstitut für Textil und Bekleidung (FTB) setzt sich dabei gezielt mit der Qualität der Alttextilien auseinander.

Im Fokus des Projekts steht die Erfindung einer Anlage, die gebrauchte Textilien je nach Materialzusammensetzung mittels Künstlicher Intelligenz (KI) automatisch sortiert. Die Deutsche Bundesstiftung Umwelt (DBU) fördert diese Forschung mit fast 400.000 Euro. Rund 100.000 Euro davon gehen davon an die Hochschule Niederrhein.

Den Anstoß dafür gab das Textil-Service-Unternehmen Dibella. Hier wird modellhaft untersucht, wie Tisch- und Bettwäsche aus Restaurants, Hotels oder Krankenhäusern am Ende ihres Produktlebens je nach Baumwoll- oder Polyesteranteil einem passenden Faser-Recycling-Prozess zugeordnet werden kann. Hier gilt wie bei der Mülltrennung auch: Je genauer die Gewebe differenziert werden, desto besser lassen sie sich in den Textil-Kreislauf zurückführen und für Neues weiterverwerten.

Bisher wird in den Großwäschereien alles von Hand sortiert. Das kostet viel Zeit und ist wegen der Menge und der mit bloßem Auge nicht erkennbaren Stoffvielfalt eine schwierige Aufgabe. Wie wäre es also, wenn Künstliche Intelligenz und moderne Technik die Alttextilien genau analysieren und ein automatisches Trennsystem die Arbeit übernimmt?

Aufgabe des FTB ist dabei die chemische Qualitätsbewertung: Es analysiert, ob gebrauchte und aus dem Mietservice ausrangierte Textilien aus Baumwolle bzw. deren Regeneratfasern oder aus Baumwoll-Polyester-Mischgewebe noch so gut erhalten sind, dass sie recycelbar sind. Konkret werden für das Projekt zunächst nur weiße Stoffe aus Industriewäschereien untersucht.

Die zu konzipierende Anlage soll im nächsten Schritt mithilfe von Nahinfrarot-Technologie und KI die Struktur und Zusammensetzung der Textilien erfassen, erkennen und sie trennscharf sortieren.
Werden anschließend Baumwoll- und Polyesterfasern voneinander getrennt, kann bei ausreichender Faserqualität der aus dem Baumwollanteil gewonnene Cellulose-Pulp (Zellstoff) für neue Celluloseregeneratfasern verwertet und in neuen Textilien eingesetzt werden.

„Unser Ziel ist es auch, die wiederholte Recyclingfähigkeit von genutzten Textilen mit Anteilen von Baumwollregeneratfasern im Hinblick auf ein vollständig geschlossenes Kreislaufsystem zu untersuchen und zu bewerten“, so Professorin Dr.-Ing. habil. Maike Rabe. Sie ist die Projektleiterin an der HSNR. „Gegebenenfalls werden wir dafür neue verbesserte Design-for-Recycling-Ansätze in Materialzusammensetzung und Gewebekonstruktion für die recycelfähigen Textilartikel entwickeln“.

Im weiteren Verlauf des Projekts soll auch ein logistisches Lagersystem für die sortierten Wäschemengen als Prototyp geschaffen werden.

Lotus Teknik Tekstil A.Ş., Türkiye, has successfully started up a complete line to produce nonwoven roll goods for biodegradable, plastic-free wet wipes. This line has been delivered, installed, and commissioned by international technology group ANDRITZ.

The neXline wetlace CP line combines the benefits of two technologies: wetlaid and spunlace. Natural fibers are processed gently to create a high-performance and sustainable wipe. This next-generation wipe, called Newipe®, combines the benefits of spunlace fabric, in particular remarkable strength in all directions, with the biodegradability and softness of a WetlaceTM fabric. It is produced with a lower carbon footprint, has a low lint rate, and does not generate dust during production.

Lotus Teknik Tekstil A.Ş. is a leading nonwoven roll good producer and a member of a group company. The group company consists of 4 companies that operate end-to-end manufacturing including nonwovens, cardboard packings, plastics, and finished wet wipe products. Headquartered in Istanbul, Sapro is the leader in Türkiye and one of the four leaders in the manufacturing of wet wipes in Europe. The company produces, converts, and supplies 161 million sheets of wipes per day for personal, household, and industrial use, exporting 70% of its production to 65 countries all over the world. Sustainability plays a prominent role in Sapro’s business strategy.

From April 25^th to 27^th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

In recognition of his extraordinary engineering achievements in the fields of textile mechanical engineering, textile technology as well as textile chemistry and surface modification of textile semi-finished products, Prof. Paul Kiekens was awarded the title of Doctor honoris causa (Dr.-Ing. h.c.) on April 5, 2023.
 
Prof. Kiekens was a university professor at Ghent University, Belgium, for almost 35 years and thus responsible for textile-oriented education and research. Intensive interaction with European business and science was always particularly important to him.
 
Immediately after the fall of the Berlin Wall, he opened the way for international cooperation in teaching and research in the field of textile mechanical engineering, textile technologies, and textile chemistry for the only Eastern European university research institution with a textile orientation, the ITM (formerly ITB) at the Faculty of Mechanical Engineering of TU Dresden, and provided great and uncomplicated support. A close, lasting and intensive relationship developed, which had a trend-setting influence on the scientific career of Professor Paul Kiekens. This was reflected above all in the expert advice given for major projects.
 
These include, for example, the funded junior research group "Holistic approach to the development and modelling of a new generation of multiaxial fabrics for fibre composites to strengthen Saxon, French and Flemish industry in the high-performance sector" (SAXOMAX) and jointly acquiring the EU project "Large scale manufacturing technology for high performance lightweight 3D multifunctional composites" (3D-LightTrans). Especially in these large-scale projects, intensive cooperation with industrial partners was essential for success.
 
As early as the 1990s, Professor Paul Kiekens had the vision of creating a European network for universities in textile teaching and research. In 1994, the Association of Universities for Textiles (AUTEX) was founded with the aim of establishing teaching and research in the field of textile technology at an internationally respected level through joint concepts. Due to the prevailing cooperation at that time between Professor Dr. Paul Kiekens and Professor Dr. Peter Offermann, the TU Dresden, represented by the ITM (formerly ITB), has been a full member and decisively integrated in the network since its foundation on July 1, 1994. Thus Prof. Dr.-Ing. habil. Paul Kiekens has significantly promoted the international cooperation of the TU Dresden, Faculty of Mechanical Engineering with international university textile research institutions.
 
Professor Paul Kiekens was executive coordinator of AUTEX until his retirement. The internationally renowned symposium takes place annually as a part of AUTEX.

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

According to statistics cited in the International Diabetes Federation Diabetes Atlas, 9th edition, globally, close to a half billion people are living with diabetes and that number is expected to increase by more than 50 percent in the next 25 years.
 
The introduction of the study in the Journal of Textile Science & Engineering also reports that diabetic patients frequently suffer from a combination of peripheral neuropathy and peripheral artery disease, which particularly affects their feet. It further states that it has been estimated that the lifetime risk for the development of foot ulcers in diabetic patients can be as high as 25 percent and that the risk of amputation is 10 to 20 times higher than in non-diabetic subjects.
 
The study was performed by Lawrence A. Lavery, D.P.M., M.P.H., a Professor in the Department of Plastic Surgery at UT Southwestern Medical Center. His clinic and research interests involve diabetic foot complications, infections and wound healing, and he participated in the conception, design, implementation and authorship of the Journal of Textile Science & Engineering study.  

CELLIANT technology is a patented process for adding micron-sized thermo-responsive mineral particles to fibers, in this case polyethylene terephthalate (PET) fibers. The resulting CELLIANT yarns were woven into stockings and gloves containing either 82% CELLIANT polyester, 13% nylon and 5% spandex or for the placebo, 82% polyester with no CELLIANT, 13% nylon and 5% spandex. CELLIANT products absorb body heat and re-emit the energy back to the body as infrared energy, which is non-invasive and increases temporary blood flow and cell oxygenation levels in the body.

The objective of the study was to “evaluate changes in transcutaneous oxygen (TcPO2) and peripheral blood flow (laser Doppler, LD) in the hands and feet of diabetic patients with vascular impairment when CELLIANT gloves and stockings are worn.” While there was not a statistically significant result across all subjects, the study did show that some patients wearing CELLIANT stockings for 60 minutes had an increase of as much as 20% in tissue oxygenation and 30% in localized blood flow. According to the study’s conclusion, “the trends that were observed in favor of CELLIANT stockings suggest that a larger well-designed clinical trial should be undertaken and may provide evidence of clinical efficacy in treatment of the diabetic foot.”
 
The study also notes that “There have been no documented or observed side effects of wearing CELLIANT stockings, and they are relatively inexpensive compared to conventional pharmaceutical interventions.”

Hologenix has embarked on a more comprehensive trial, “Study to Evaluate CELLIANT Diabetic Medical Socks to Increase Tissue Oxygenation and Incidence of Complete Wound Closure in Diabetic Foot Wounds” – NCT04709419, which focuses on the impact of CELLIANT technology to potentially improve tissue oxygenation and wound healing outcomes.
 
“We are excited to explore whether future studies of infrared, with its most common biological effects of increased localized blood flow and cellular oxygenation, could result in a breakthrough in diabetic patients with vascular impairment,” said Seth Casden, Hologenix Co-founder and CEO. “We see a huge potential opportunity with this research for helping to fulfill our core mission of improving people’s health and well-being by potentially reducing the impact of diabetes, and we are actively seeking partners to expand our research efforts.”

After the recent acquisition of Texo S.R.L. which has strengthened the company's presence in the luxury segment, C&S takes a further step forward in the creation of a widespread garment manufacturing hub in the heart of Italy. C&S takes ownership of the Seville brand together with the Bianchetti family, who remain co-owners covering mainly style research and development functions. The Italian style, which amounts to an aesthetic identity and a guarantee of artisan quality, a cultural orientation toward manufacturing excellence and product design, finally to an approach to the market characterized by availability, openness and interaction with the customer.

This acquisition strengthens C&S direct contact with retail, going alongside HAIKURE, PDF and other brands still being finalized, and will be able to generate a profitable exchange with the Style Services Luxe and Style Services Denim divisions, through which C&S stands out as an exceptional partner for all the brands that choose to rely on its experience in the world of jeans, luxury and formalwear.

High quality and Made in Italy trousers, but there is more, the brand Siviglia from the Marche region brings to C&S a wealth of tailoring skills and product construction. Born in Marotta (PU) in 2006 from the Bianchetti family, Siviglia is a reality that has experienced rapid commercial success since its entry into the market thanks to the intuition of the iconic trousers with fabric inserts at mid-thigh inspired by the Spanish horsemen, hence the name that recalls the Andalusian capital.

The success of Siviglia is built on coats, trousers and jeans characterized by fit and linear style, thanks to the continuous research on the product, on the fabrics and on the emerging trends, in a personal reinterpretation of the codes of elegance. The corporate style permeates not only the choice of materials and accessories, but is distinguished by the packaging components and the use of visual and communicative languages in line with the brand identity. By interpreting the contemporary and foreseeing the future needs of a constantly evolving market, Siviglia aims to provide its customers with the best in the broadest sense, including among its qualitative goals the reduction of the environmental impact of productions and materials used.
