From the Sector

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

• Session "New Technologies for Pulp, Fibres and Yarns"

Cellulose fibres are a true material miracle as they offer a steadily expanding, broad range of applications. Meanwhile markets are driven by technological developments and policy frameworks, especially bans and restrictions on plastics, as well as an increasing number of sustainability requirements. The  presentations will provide valuable information on the various use-opportunities for cellulosic fibres through a policy overview, a special session on sustainability, recycling and alternative feedstocks, as well as the latest developments in pulp cellulosic fibres and yarns. In addition, examples of non-wovens,  packaging and composites will offer a look beyond the horizon of conventional application fields.

The extensive fifth conference session, “New Technologies for Pulp, Fibres and Yarns”, includes the participation of eight speakers and promises the reveal of various innovations and new approaches. These address the processing of pulp, fibres and yarn, with the aim of realizing most sustainable and efficient solutions. The broad spectrum of topics ranges from processing cellulose with ionic liquids, material farming and chemical modification of pulp to functionalised fibres for feel-good textiles.
