Lenzing and KARL MAYER GROUP collaborate

Updated: Jun 5, 2023

To empower sustainable and aesthetic innovations in flat and warp knits

The strategic partnership strives to increase the adoption of fossil-fuel-free materials with the goal of achieving a greener textile value chain

The partnership will facilitate the adoption of up to 100% botanic and biodegradable fibers and filament in warp knitting machines for sustainable, aesthetic applications

The collaboration aims to encourage climate pioneers to further lower their carbon emissions with the use of carbon-zero TENCEL™ branded fibers while using the STOLL flat knitting machines of the KARL MAYER GROUP

Lenzing, 24 May, 2023 – Lenzing Group, a leading global producer of wood-based specialty fibers, announced a strategic collaboration with KARL MAYER GROUP, a world leader in textile machinery, to enable the smooth adoption of a higher percentage of botanic, biodegradable and fossil-fuel-free materials during textile production in both warp knitting and flat knitting machines.

With consumers being more mindful of the environmental impact of the products they purchase, there is a growing trend among leading brands and retailers to offer products that are more sustainable and aesthetical. This partnership will enable the adoption of TENCEL™ Lyocell fibers and TENCEL™ Lyocell filament yarn in warp knitting machines and further reduce the environmental impact of using STOLL flat knitting machines with the use of carbon-zero TENCEL™ fibers in its fully fashioned flat knitting process. As a strategic collaboration between Lenzing and KARL MAYER GROUP, the partnership represents an important step by the two companies in guiding the industry towards a more sustainable future and underscores their commitment to empowering partners in the textile chain with value-added solutions and innovation in reducing the carbon footprint of their supply chains.

“As a key player in the industry, Lenzing continues to join hands with like-minded partners to pioneer solutions that improve the quality of textile products and enable the ongoing sustainable development and growth of the industry. Through this partnership with the KARL MAYER GROUP, we will inspire the textile value chain to take proactive steps towards achieving their climate goals with easier adoption of botanic and biodegradable materials, meeting the needs of brands and consumers who are looking for eco-conscious products,” said Florian Heubrandner, Vice President Global Textiles Business at Lenzing.

“The KARL MAYER GROUP is a leading manufacturer of textile machinery and always has its finger on the pulse of its markets. In addition to productivity, sustainability has become a key success factor for our customers. We work with pioneers throughout the textile value chain to provide them with solutions that have a low environmental impact. Yarn is particularly important in this respect. Recycled man-made fibres can be used with high efficiency on our machines. We want to expand the range of materials that can be processed to include petroleum-free yarn variants through our cooperation with Lenzing. In addition to more sustainability, this will also open up the potential for new product developments,” explained Arno Gärtner, CEO of KARL MAYER GROUP.

Increasing adoption of fossil-fuel-free materials in Warp Knitting machinery

With more value chain partners and brands opting for sustainable raw materials, we need to ensure that existing equipment or machinery that traditionally caters to fibers or yarn made of fossil-based materials can adapt well to botanic alternatives. The partnership between Lenzing and KARL MAYER GROUP strives to enable fossil-fuel-free materials such as TENCEL™ Lyocell fibers and TENCEL™ Lyocell filament yarn to be processed and optimized on KARL MAYER warp knitting machines and demonstrates the possibilities and varieties that can be created in addition with botanic and biodegradable materials.

Leveraging Lenzing’s technical knowledge of the processing of TENCEL™ Lyocell fibers and filament within the value chain, the partnership also supports yarn makers and spinners in their continuous development and adaptation of yarn for new and different textile applications.

Pave the way for a sustainable textile value chain with upgraded Flat Knitting features

With a shared vision to lower the environmental impact of the production process, the collaboration reduces carbon footprint with carbon-zero TENCEL™ fibers and decreases material consumption on STOLL flat knitting machines. The knitting method has been applied to an ultrafine flat-knit fabric on gauge 20 machines which qualify to be used for making underwear. The fully fashioned process is new to this field as in underwear cut & sew fabrication is established as best practice. Coupled with the adoption of renewable energy sources in textile production plants and effective supply chain management, Lenzing and KARL MAYER GROUP marry sustainability with innovation to empower manufacturers to achieve ultra-low carbon emissions using botanic and fossil-fuel-free fibers during the production process.

Lenzing and KARL MAYER GROUP will be showcasing a series of concept products, technical samples and fabrics at the upcoming ITMA 2023 tradeshow in booths (Hall 2-E212 and Hall 4-B-119) to illustrate the potential of knitting innovation leveraged through the collaboration. From then onwards, textile value chain partners can contact Lenzing and KARL MAYER GROUP to discuss how to achieve greater sustainability in their own operations.
