From the Sector

The Top Employers Institute has recognized Autoneum as a Top Employer 2024 in Switzerland. Being certified as a Top Employer showcases an organization’s dedication to a better world of work and exhibits this through their policies and people practices. This year, the automotive supplier's Human Resources (HR) department at its headquarters in Winterthur, Switzerland, took part in the comprehensive survey of the Top Employers Insti-tute for the first time and achieved an outstanding result.

The institute has been auditing companies worldwide for over 30 years. The certification program, which is based on an international standard, makes HR measures and their impact on employee conditions objectively measurable. To achieve this, the Top Employers Institute certifies organizations based on the participation and the results of their HR Best Practices Survey. This survey covers six HR domains consisting of 20 topics including People Strategy, Work Environment, Talent Acquisition, Learning, Diversity, Equity & Inclusion, Wellbeing and more.

The program has certified and recognized over 2 300 Top Employers in 121 countries/regions across five continents.

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.

With the next generation of soft and stretchable electronics, reproducible and stretchable conductive inks are playing an increasingly important role in areas such as smart textiles, medical textiles or wearables. Saralon produces a range of stretchable conductive inks including Saral StretchSilver 500 for e-textile applications.

While electronic applications integrated into textiles gain popularity, printed stretchable conductive inks emerge as a transformative alternative for the complicated approach of weaving conductive yarns and fibres.

Just like choosing the right fabric and additives is vital for smart textile development, selecting the right conductive ink matters too. There are challenges to consider, such as conductivity, ink penetration into the fabric, changes in physical properties most importantly stretchability, printing process controllability, and reproducibility. That's why research and analysis are essential when deciding on the best conductive ink for a project.

Together with the Saxon Textile Research Institute e.V. (STFI) Saralon conducted some performance tests benchmarking our Saral StretchSilver Ink against some competitor product.

Results:
Conductivity:
Saral StretchSilver 500 consistently demonstrated superior conductivity, regardless of line width.

Fluctuations at lower widths:
Both inks exhibited fluctuations at narrower printed lines, but the Alternative Ink displayed significantly higher variations.

Reproducibility Insights:
Saral StretchSilver 500 maintained stable resistance at 2mm and beyond, while the Alternative Ink noticeably struggled.

Elongation behaviour:
Saral StretchSilver 500 harmoniously coexists with the textile. Its application has minimal impact on the fabric's stretching properties, ensuring stability. The Alternative Ink, on the other hand, leads to significant changes in textile’s elongation properties. With this ink, stretching demands considerably higher forces.
