From the Sector

The report details sustainability efforts at its Boennigheim headquarters and targets for 2024. Hohenstein has replaced previous environmental guidelines with strategic development in accordance with Environmental, Social and Corporate Governance (ESG) and adopted a sustainability roadmap for the future.

Hohenstein has been implementing environmental and social measures for decades. As the first neutral assessment of these measures in 2019, Hohenstein participated in the ECOfit programme in Baden-Württemberg, Germany. A regular external assessment is to be introduced in 2024.

• Environmental: Overall, energy consumption was actively reduced, and renewable energy use promoted. Hohenstein also collected rail and air travel data to be used in CO2 accounting in 2024.
• Social: Hohenstein actively involved its employees in sustainability activities based on a survey and internal education. In future, Hohenstein will improve the ratio of female managers and implement a training campaign on the company values for employees.
• Governance: Hohenstein management has prioritized good communication through regular colloquia for employees and access to human resources consultation. They intend to intensify the dialogue with employees through further events.

In der Textilverarbeitung ist Infrarot-Strahlung eine bewährte Wärmequelle. Sie überträgt kontaktlos hohe Leistungen in kurzer Zeit. Dadurch kann Energie eingespart und die Produktionsgeschwindigkeit erhöht werden. Letztlich werden die Produktionskosten minimiert. Infrarotsysteme sind sehr kompakt und können eine hohe Leistungsdichte auf einer kleinen Fläche erzeugen. Daraus resultieren kleine Anlagenlayouts und ein geringer Platzbedarf in der Produktion.

• Infrarot-Strahler übertragen Wärme kontaktfrei
• Kurze Reaktionszeiten erlauben eine exakte Temperaturführung
• Optimal abgestimmte Infrarot-Strahlersysteme erhöhen die Prozessgeschwindigkeit, verbessern die Qualität und sparen Energie

Fixierung von Teppich Bahnen bestehend aus Textilgewebe und Bitumen Laminierung
Durch die Verwendung von Infrarot wird stets eine konstante Bitumentemperatur beim Laminieren mit dem Textilsubstrat gewährleistet unabhängig von der Produktionsgeschwindigkeit (sogar nach Maschinenstillstand) und unabhängig von der Umgebungstemperatur. Dadurch wurde das Problem der Delamination gelöst.

Trocknung von Baumwollgewebe auf 2% Restfeuchte
Das System erzeugt eine konstante Restfeuchte bei variierender Produktionsgeschwindigkeit von 10-100m/min und über die vollständige Gewebebreite.
Der Trockenofen ist vertikal aufgebaut, wodurch sehr wenig Platz von nur 1m für 200kW benötigt wurde.

Vorwärmung von Nadelfilz Matten
Das Gewebe wird über die gesamte Produktionsbreite von 5000mm am Eingang des Umluftofens mit einer erhöhten Temperatur (± 60°C zusätzlich) angeliefert, und zwar unabhängig von der Produktionsgeschwindigkeit. Die Prozess Geschwindigkeit konnte auf 12m/min. erhöht werden.
Nahtlose Integration in den zur Verfügung stehenden Platz auf der Produktionsmaschine. Es waren lediglich 500mm in Durchlaufrichtung erforderlich.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

With an investment in an Innovation Center with testing labs and additional production facilities, Carl Meiser GmbH&Co KG gives a clear statement to it’s location in Albstadt in Central Europe. As well this underlines the know-how and the motivation of the whole team. The constructions were already launched. The first buildings for production and a part if the Innovation Center will be ready end of this year. State of the art offices and social facilities will be ready to move in mid of 2019.

“After our suffered setback with the fire in our production facilities in November 2017, this investment will move us much more forward and will give us the motivation to offer our customers even better and more innovative service and products. In long-term view this will creates the base for further growth”, says Jens Meiser CEO of Carl Meiser GmbH&Co.KG. During the last months we already invested in production technology and machines. During the last weeks we changed the complete production organisation to reach a lean product flow.

As well Meiser expanded it’s apprenticeship programme during the last years. At the moment we apprentice new staff members in three different education programmes. It is planned to add a fourth in management in future.

The company Carl Meiser GmbH&Co.KG with it’s brand „MEISER – Know How in textiles“ delivers to the high end underwear and lingerie industry as specialised dyehouse for knitted fabrics. With the brand “NOPMA technical textiles” the company acts as a fast growing development and production partner for the aviation, automotive and furniture industry as well the protection fabric industry. For this industries coated fabrics are developed and delivered to the markets. “In this sector we grow continuous during the last years. We are convinced that our investment in the Innovation Center will support this growth next to our first presence as exhibitor on the fair Techtex in 2019”, says Jens Meiser.

In the approval phase the company was supported by the city of Albstadt in all necessary questions. Fast and possible solutions were found. This shows the Mittelstands-friendly climate in this region in south Germany. The invest is supported by the national programme “Spitze auf dem Land” by the country of Baden-Württemberg and the EU.
