From the Sector

Biella Yarn’s new Fall/Winter 24/25 collection presents two collaborations. Both collaborations start with one common inspiration: with the clash of different cultures and the distant exotic markets. Rug making, fur-crafts and artisan hand work inspire patterns and textures which are translated into knitted fabrications and 3D designs.

MRC Knitwear Research Lab created these textures and patterns by using a small selection of very classic yarns and working them in special techniques to create rich textural fabrications. Each garment focuses on a special technique and combination of yarns and colours and show how versatile a single yarn can be.

The garments were knitted mainly with Victoria Nm 2/30 (100% Merino wool extrafine, 19.5 μ, anti-shrinkage). Victoria Nm 2/30 was used in an array of different techniques and on different gauges - from 14gg ribs, that have a beautiful drape to more tactile fabrics such as 3-dimensional stitches on 12gg and heavily patterned inlay jacquards on the 14gg Shima Seiki SRY. Within these inlay jacquard’s BaltoroPro Nm 2/28 (70% Merino wool extrafine, 19.5 μ, anti-shrinkage 30% Polyester GRS High Bulk) was selected as an inlay yarn - a special wool blend which helps create bulky 3-dimensional fabrications that remain lightweight. The classic Brisbane Nm 2/60 (100% Merino wool Superfine, 17.5 μ, anti-shrinkage) and new boucle yarn Fluffy Nm 14 000 (81% Merino wool extrafine, 19.5 μ, anti-shrinkage, 19% Polyamide) were worked together in fine plush jacquards to give an effect of shaved patchwork furs.

The structures and patterns were transitioned into the world of 3D designs by Shima Seiki Italia. The design software APEXFiz®, developed by Shima Seiki, not only allows for shaping but also converts them into knitted patterns. By replacing physical samples, virtual samples reduce time costs, and materials that would otherwise be wasted. Yarnbank®, Shima Seiki's platform for yarn and spinning research, has been the primary source of Suedwolle Group's digitized yarns used in the 3D models.

The KARL MAYER GROUP and the Südwolle Group have joined forces in a project to explore the possibilities of merino wool for warp knitting technology. The project was triggered by the increasing demand for textiles made from sustainable and environmentally friendly materials. The cooperation was to develop innovative fabrics from renewable raw materials for use in underwear and functional sportswear. The focus of the work was on the use of wool as a material with excellent comfort properties and the look and feel of lightweight single jersey goods. The natural fiber fabric qualities are not typical for warp knitting processing, so the challenges during the project work were diverse.

Merino wool yarns with good running properties
Regarding the choice of material, the product development team of Südwolle Group recommended the Hidalgo yarn from their product portfolio. The yarn was created using the in-house developed Betaspun technology, in which a filament was twisted around a merino core. When natural fibres such as wool, cotton or silk are combined with sustainable fibres such as biodegradable polyamide as the filament, the spinning process can create durable, lightweight yarns that disintegrate completely without residue after use. The yarns made from the two components also have good running properties for use in warp knitting. "The polyamide content of the yarn increases its tenacity, reduces hairiness and makes it an excellent choice for warp knitting technology," confirmed Gabriela Schellner from KARL MAYER's Textile Product Development Department.

Shape stability paired with single jersey "look and feel"
The Hidalgo yarn, which is made from merino wool, was processed on a warp knitting machine using a carefully thought-out lapping selection to produce a light, soft fabric which, above all, retains its shape. The textile specialists at KARL MAYER had experimented with two different single bar fabric qualities beforehand and had thus adopted a new approach for jersey machines.

The first results are promising. Now more trials are needed to perfect the technique. Development partners are needed, including fabric producers, brands, and garment manufacturers, with whom the fabric qualities, machine equipment and orientation to the end applications can be refined. The KARL MAYER GROUP and the Südwolle Group are also unanimous in their desire to push the boundaries of what is possible with merino wool and knitting technology and to develop new solutions for the textile industry through further project work.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

APEXFiz® subscription-based design software supports the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes. By replacing physical samples, virtual samples reduce time, cost and material that otherwise go to waste. APEXFiz® thereby helps to realize sustainability and digitally transform the fashion supply chain.

Continuing from past editions of Pitti Filati are knit samples produced in collaboration with Italian designer Vittorio Branchizio, as well as samples from SHIMA SEIKI headquarters for assessing the potential of SHIMA SEIKI knitting machines.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

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.

Freudenberg Performance Materials Apparel is expanding its Super Elastic Interlinings Range with the introduction of the apparel industry’s first 100% recycled thermoplastic elastomers (rTPE) base content interlining series. In recognition of the growing use of elastic interlinings in apparel and building on the principles of Freudenberg Performance Materials´ Apparel’s House of Sustainability, these new products speak for high-quality and sustainable solutions.

The new, 100% rTPE base content interlinings are offered in 40-90 g/m2 weights, with wide applicability – from lightweight knit fabrics with applications in leggings and sports bras to elastic woven fabrics that require medium-to-heavy weights, such as denim, maternity clothes, or casual wear. Sustainable without compromising on quality, the new interlinings offer exceptional elasticity and retain excellent recovery capabilities.

The 100% rTPE base content interlinings reduce the need for virgin materials in apparel while also reducing the demand for the extractive practices necessary to produce such materials. Furthermore, the use of recycled components reduces materials in landfills and oceans, in consideration of full-garment lifecycle management.

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.
