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.

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.
