From the Sector

The Karl Mayer Group is reducing its ecological footprint when it comes to energy utilisation: The Group's largest photovoltaic system to date has just been installed at its headquarters in Obertshausen.

Following the construction of a stable substructure, the first photovoltaic elements were installed on the roof of the assembly hall in Obertshausen on 16 February 2024. This will be followed by the step-by-step conversion of other roofs. If everything goes according to plan, around 6,000 modules will have been installed on an area of approx. 12,000 m² and over 60,000 metres of cable laid by the middle of the year.

"With a total output of 2.4 MWp, we will be able to generate over 35% of the total electricity consumption at the site ourselves," explains Michael Sustelo, Head of Facility Management at the Karl Mayer Group.

ANDRITZ recently started up a new textile recycling line at Sfilacciatura Negro’s plant in Biella, Italy. Designed for processing post-consumer textile waste with automatic removal of hard parts, the tearing line supports the company’s expansion into new recycling segments.

In view of the growing demand for sustainable fibers in the re-spinning and nonwoven industries, Sfilacciatura Negro Biella decided to expand its recycling capabilities. The company has extensive experience in recycling industrial textile waste and already operates two tearing lines. Based on its long-term collaboration with ANDRITZ, it is now stepping into the recycling of post-consumer clothing waste.

The new generation recycling line ANDRITZ supplied to Sfilacciatura Negro is the result of ten years of close cooperation, trials in its technical center, and visits to customer lines in Spain and Portugal. ANDRITZ has tailored a complete line from feeding of sorted waste bales to baling of the recycled fibers. It is designed for highly efficient, energy-saving operation and features automated separation of hard points while maintaining a good material yield. An automated filtration unit is provided for airflow and dust management. Only one operator is needed to manage the entire line up to the recycled fiber baler. The baler can produce film-wrapped and tied bales with a weight of up to 350 kg.

The new Orthopac RXVMC-20 automatic straightening system for forward control of knitwear with strong distortions can remove distortions in textile webs even faster and more precisely.

"With the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the scanner system," explains Head of Sales Thomas Höpfl. Two individually controlled and driven straightening modules with a total of four bow and three skew rollers ensure that the correction of bow and skew distortions takes place in small steps. The control concept is also new. A scanner group at the infeed of the straightening machine detects distortions even before they reach the correction rollers. This way, the rollers are brought directly into position and the fabric is corrected from the very first centimetre. A scanner group at the outlet also detects possible residual distortion, which is corrected at the second straightening module. This enables an even more precise and faster response when it comes to reacting to rapidly changing distortions.

The Orthopac RXVMC therefore shows its full strength when straightening knitwear and distortion-sensitive fabrics. Knitted fabrics are special in terms of distortion dynamics. It is difficult for operators when changing the fabric rolls to join the relatively short fabric webs with weft and loop-straight seams. Before and after unavoidable insufficient seams, the distortion (e.g. right before to left before) changes abruptly. Conventionally, the distortion change is only detected by scanning at the output of the straightener.
 
The RXVMC concept enables a shortened reaction time to jumping distortion, (especially in the case of seams) due to the improved scanning concept with scanning at the outlet and inlet. This reduces knitted fabric outside the straightening tolerance up to 50 percent after each seam. Fewer fabric pieces have to be reprocessed. It guarantees higher quality goods and thus less waste.

ITM Exhibitions will open its doors to host "ITM 2024 International Textile Machinery Exhibition" from June 4-8, 2024. Preparations are in full swing for the organization, where textile technology leaders will bring the latest products together with their visitors for the first time.

The ITM team focused on advertising and promotional activities in order to host thousands of visitors and sector investors from all over the world at the ITM 2024 Exhibition, which halls were almost full due to intense participation demands. In this context; 'ITM 2024 Video', which tells the story of the increasing success of ITM exhibitions over the years and which is eagerly awaited by the whole sector, has recently been published. The video, which was published in Turkish and English on social media accounts such as YouTube, LinkedIn, Instagram, Twitter and Facebook, was viewed by more than 30 thousand people in total and received great appreciation from the viewers.

“Discover the Future!” in the video prepared with the main theme “Discover innovations, technologies, the future...” and including clues about the ITM 2024 Exhibition, was revealed as follows:
The textile sector is among the souls of the economy with its production capacity, export volume, and contribution to employment. Many R&D centers around the world and in Turkey are breaking new ground by taking their work and innovations one step further every day. Textile technology leaders are developing technologies that consume less water and energy, are easy to use, are software and automation supported, keep up with trends and respect the environment while doing so. Industry stakeholders, especially textile manufacturers, are now curious about the answer to this question: 'What will be the future of the textile industry, which is digitalizing, complying with sustainability principles, and signing groundbreaking innovations? This question will be answered at ITM 2024, which will host the latest innovations, technologies, artificial intelligence-supported machines, software and design excellence devices in textile machinery.

The German companies Brückner, Groz-Beckert, the Karl Mayer Group and Thies invite representatives of the Indian textile industry to a symposium with presentations and discussion panels in Surat, India, on October 11 and 12, 2023. The event will be held at the Marriott Hotel Surat and will focus on the current demand trend for warp knitted elastic fabrics.

The demand for warp knitted elastic fabrics has increased rapidly in the past two to three years. On the one hand, this offers the Indian textile industry new growth opportunities and the chance to establish itself in a leading position in the growing market. On the other hand, the turnaround also holds challenges as the production steps involved in manufacture of warp knitted elastic fabrics are strikingly different from the conventional methods.

In order to provide the Indian warp knitting industry with optimum support in this change, Brückner, Groz-Beckert, Karl Mayer and Thies are inviting participants to a specialist symposium on the subject of "Production of Warp Knitted Elastic Fabric". Industry experts, stakeholders and textile visionaries are invited to share their insights and experiences with the guests.

The aim of the symposium is to provide a platform where knowledge can be exchanged and cooperation intensified. The symposium offers a wide variety of technical presentations as well as best practice examples and showcases technologies and innovations in warp knitting technology.

Those interested in attending the symposium may contact Vinod Kumar (Brückner & Thies), Dipak Panhalkar (Groz-Beckert) or Apurva Jariwala (Karl Mayer) to register.

adidas unveils its new campaign to celebrate the FIFA Women’s World Cup Australia & New Zealand 2023™. The campaign is dedicated to next gen icons Alessia Russo, Lena Oberdorf and Mary Fowler and looks to drive more global attention for the game and inspire other young women and girls to follow in their footsteps.

Marking adidas’ most impactful Women’s World Cup campaign to date, the brand unites its global family of football legends and advocates of the women’s game. Headlined by a series of fast-paced films, the campaign welcomes a star-studded line up of David Beckham, Leon Goretzka and Ian Wright, actor and football fan, Jenna Ortega, as well as Argentina’s World Cup hero, Lionel Messi. They come together to celebrate the skills that Russo, Oberdorf and Fowler are renowned for, from vision and interception to power, creativity and accuracy.

The films are part of a new creative proposition from adidas for the upcoming tournament. ‘Play Until They Can’t Look Away’ aims to platform and showcase some of the world’s greatest football players on the biggest stage – whose skills and passion for the game demand global attention and support.

Set against the soundtrack of SL2’s iconic song, On a Ragga Tip, fans see World Cup winner, Lionel Messi, alongside Mary Fowler, guiding both viewers and Jenna Ortega across the world to Fowler’s home country of Australia , with preparations for the biggest women's sporting moment underway.

Meanwhile, David Beckham and Ian Wright, alongside his granddaughter, Women’s Arsenal FC player, Raphaella Wright-Phillips, are unable to look away in a supermarket as Russo spectacularly weaves her way through the narrow aisles, in her own creative fashion. Finally, Goretzka is expertly interrupted while bowling as Oberdorf whizzes around an arcade, powerfully intercepting balls in each scene to achieve a high score of her own.

Paying respect to those who have gone before, the films are also filled with subtle references to memorable moments that football super fans will revel in, including shirt numbers, iconic tournament balls, plus much more.

Just in time for ITMA 2023 in Milan, the flat knitting machine manufacturer STOLL has launched its new collection COLOR IN KNITTING. It holds a range of knitting techniques that were ideated for novel super fine machine gauges such as the E20.

In addition, STOLL reveals its internal design workflow, showcasing how digital software tools can speed up the design process. The core of this is k.innovation CREATE DESIGN. Through the utilization of STOLL’s jointly developed design software solution, k.innovation CREATE DESIGN, in collaboration with @KM.ON, the shape and structures of a garment, can be digitally created, allowing for its simulation before it is even knitted. The interfaces to various external 3D software tools, allow for a realistic representation of the garment facilitating faster design decisions. Once the virtual knits, made in the CREATE DESIGN software are ready for manufacturing, it will be send to a knitting technician for further processing in k.innovation CREATE PLUS, This significantly speeds up product development while reducing communication issues between designers and technicians.

Sustainability and responsible handling of precious natural resources were key factors driving the development of the latest trend collection, COLOR IN KNITTING. STOLL-knit and wear®, a technique that stands for seamless knitted garments, can play a significant role in reducing waste. In addition, fewer process steps are required in the production chain - with advantages for production efficiency.
For another highlight of COLOR IN KNITTING, the STOLL creatives have worked on imitating different yarn effects with knitting technology such as slub yarn optics or the simulation of fabrics like crepe de chine/crepe georgette

On the occasion of the 150th anniversary of STOLL, COLOR IN KNITTING features a selection of vintage pattern replicates. These patterns can be found in STOLL’s extensive sample archives in Reutlingen. It is impressive to learn that all these former fabric constructions can still be replicated today and also reinvented with todays machine features. This approach showcases the steep progression of technical advancements over the past 150 years.

STOLL´s latest trend collection culminates in the creation of an invaluable resource: the book “Color in Knitting: By Designers, for Designers”. This publication aims to cater to a diverse audience by presenting a comprehensive guide to designing with colors using various flat knitting technologies and will be presented in the chapter "Book release".

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.

• Longer parking times for greater efficiency

Since 2018, Oerlikon Barmag has been offering the market’s only currently available concept for high-end home textile applications using the POY and DTY process. The spinning concept with the WINGS HD winding unit in conjunction with an automatic eAFK Big V Multispindle texturing machine manufactures high-titer yarns with maximum machine efficiency.
 
“We have correspondingly modified WINGS HD in order to once again better align the increased requirements of these special yarns to the spinning process and make everyday production even simpler for our customers”, comments Stephan Faulstich, POY Process Technology Manager. The parking times are extremely short when winding high titers. We have increased the parking times by up to three times in the case of the new WINGS HD models. To this end, the parking time for a 300d/384f yarn, for example, has been increased from a standard 6.5 min. to 15.7 min. – and, in the case of a 400d/192f yarn, from 4.3 min. to 10.3 min. This makes the doffing process more even, hence increasing doffing reliability.

At the same time, the draw unit now has a more flexible design, meaning that two-godet operation is also possible in the case of products with low overall titers. This has a positive impact on the winding unit’s energy consumption.

12 POY packages of up to 600d/576f (final) are produced in the spinning process using WINGS HD 1800. This is made possible as a result of an additional godet, which ensures that the high yarn tensions developing in the process are reduced to the yarn tensions common in the case of the winding process to date. At the same time, the newly-developed suction unit with the accompanying yarn cut-ting device (yarn collecting system) ensures – both during string-up and in the event of a yarn break – reliable handling of the yarn with an overall titer of 7,200 den (final).

Whereas DTY yarns up to 1,200 den and with up to 784 filaments have in the past, as standard, been plied from four POY 300d/192f bobbins using DTY machines, high titers can also be manufactured directly using the WINGS HD take-up machine. Combining the WINGS HD and the eAFK Big V allows all available winding positions to be utilized during texturing.
