From the Sector

As part of the European Erasmus+ project AddTex, the partner organisations organised several hackathons at the universities of Boras (Sweden), UPC (Spain), PIN (Italy) and TUS (Ireland) in May. The aim is to connect students with real challenges in the industry and promote innovation in the areas of ecology, sustainability, digitalisation and design. The participants had received basic information in advance through the 45 training videos and training sessions of the free and public Smart, Digital and Green Skills Academy at https://addtex.eu.

The hackathon at the Italian university PIN (Polo Universitario Città di Prato) was organised and held together with the technical textiles department of the Industrieverband Veredlung - Garne - Gewebe - Technische Textilien e.V. (IVGT). Eight teams competed to develop innovative, sustainable ideas in just a few hours for the German family business Schmitz Textiles GmbH & Co. KG, Emsdetten. Schmitz Textiles, an expert in complete textile solutions for indoor and outdoor use for over 100 years, plans to offer exclusively sustainable products in the medium term and is looking for solutions to continuously increase the existing recycled share of yarns to 100 per cent.

Stefan Schmidt from IVGT presented the challenge via Teams Conference: "We are looking for a new business model for textile recycling at awning manufacturer Schmitz-Textiles in order to increase the existing proportion of recycled yarns and go beyond the exclusive use of recycled PET bottles. Schmitz Textiles has had an awning fabric made from 100% recycled polyester in its range since the end of 2023. The medium-term goal is to switch the entire range of awning fabrics to 100% recycled yarns. The company is looking for suitable solutions to achieve this.

In small teams, the 30 students specialising in eco-design, textiles/sales and textiles/technology developed proposals and presented them in five-minute online pitches. Ralf Bosse for Schmitz Textiles and Iris Schlomski for the IVGT acted as the jury and assessed the individual presentations in the categories of degree of innovation, presentation, industrial application potential and potential for commercial success. Each idea presented and each presentation scored more or less points in the individual categories. In the end, the points scored were added up to determine the winning team, which can further develop its idea together with the company. For Schmitz Textiles, these are Eleonora Boccherini, Ilaria Ioja, Giorgio Gacci and Marianna Butera.

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.
