From the Sector

At ITMA 2023 in Milan from June 8-14 this year, Monforts is organising two free-to-attend seminars and discussions on the potential of green hydrogen as a new energy source for textile finishing, drying and related processes.

Monforts is currently leading a consortium of industrial partners and universities in the three-year WasserSTOFF project, launched in November 2022, that is exploring all aspects of this exciting and fast-rising new industrial energy option.
The target of the government-funded project is to establish to what extent hydrogen can be used in the future as an alternative heating source for textile finishing processes. This will first involve tests on laboratory equipment together with associated partners and the results will then be transferred to a stenter frame at the Monforts Advanced Technology Center (ATC).

To be considered “green”, hydrogen must be produced using a zero-carbon process that is powered by renewable energy sources such as wind or solar. Currently, the cleanest method of hydrogen production is electrolysis, using an electrically-powered electrolyzer to separate water molecules into hydrogen and oxygen. The purity of the hydrogen is also important, and impurities must be removed via a separation process.

“Despite all its advantages, there are obstacles to overcome on the way to widespread, economically-feasible green hydrogen use,” explains Monforts Textile Technologies Engineer Jonas Beisel. “Until there are widely available, reliable and economical sources of this clean power, the cost of producing it will remain prohibitive. The infrastructure is not yet there, and hydrogen also has a tendency to make steel brittle and subject to fracture, which is something that requires further investigation in both its transportation and use in industrial processing.
“Green energy’s potential as a clean fuel source is tremendous, but there is much we need to explore when considering its use in the textile finishing processes carried out globally on our industry-leading Montex stenter dryers and other machines.”

At its Advanced Technology Center (ATC) in Mönchengladbach, Monforts will be carrying out intensive tests and trials to assess the reliability of both processes and final products when different natural gas and hydrogen mixtures – up to 100% green hydrogen – are employed. The results will be closely analysed by the consortium partners because there are many parameters that at this stage remain unknown.

The aim, Beisel adds, is to both reduce CO₂ emissions and – following the rising prices and industry turbulence experienced by manufacturers over the past year or so – to further reduce a dependency on natural gas.

The three-year WasserSTOFF project is sponsored by Germany’s Federal Ministry for Economic Affairs and Climate Action, and with Monforts at the helm brings together industrial partners Pleva and NTB Nova Textil, with academic input from the Hochschule Niederrhein and the Technical University of Freiberg.

• Polynova to gain market share for the GRAFE Group in the Swiss region from November The GRAFE Group, Blankenhain, has found a new sales representative for Switzerland in Polynova Group AG, Risch-Rotkreuz (Switzerland).

The partnership will be officially launched at Fakuma 2021. "Our new Swiss agency specialises in the distribution and production of high-quality technical plastic granulates and has been active on the market for more than 20 years. The company has a large customer base and the necessary technical expertise to advance our goals in this important market. This includes raising our profile, educating people about our product range and ultimately gaining market share," says Stefanie Theuerkauf, Sales Manager for the D-A-CH region. Polynova employs five sales staff and three in logistics, all of whom have a technical background. The company's own warehouse in Rothenburg also ensures the availability of the plastics.

"GRAFE fits perfectly into our product portfolio," says Thomas Weigl, co-owner and responsible for business development at the Swiss distribution company, whose employees recently underwent intensive training in Blankenhain. "Our customers come from the sports goods, housing technology, automotive supplier and medical technology sectors - there are many synergies with GRAFE." Weigl himself has extensive experience in the masterbatch sector and has worked for two companies in the industry - Sukano and Americhem - as managing director. "Swiss companies want Swiss contact persons. We speak the languages German, Italian and French, are on site in the shortest possible time, offer direct contact and understand the needs of the customers and the requirements of the market," he explains. "Polynova is thus faster, closer and more direct." "The Swiss market is large and important for us," reports Theuerkauf and Weigl explains the background: "There are over 300 plastics processors, many are family-run and very technically oriented. The origins of the companies are often in the watch industry and in the production of the smallest precision parts such as gear wheels. In addition, coffee machine manufacturers, medical technology providers and automotive suppliers are important market players. A large number of well-known OEMs are located here."

Even though there are already masterbatch manufacturers in the Alpine country, says the sales expert, no one has the know-how to adjust compounds and masterbatches as perfectly and precisely as the company from Thuringia. In addition to a complete range of colours on practically all plastic substrates, flame retardants, UV additives, thermal stabilisers or lubricants are further examples of the extensive product portfolio. GRAFE is one of the specialists in the modification of thermoplastics and is an innovation driver in the production of colour masterbatches. "The technical possibilities in terms of a state-of-the-art technical centre and production machinery, as well as one of the largest research and development departments in the industry, are also not to be found elsewhere on the Swiss market. Our task now is to bring these to the attention of domestic customers," says Thomas Weigl, co-owner of Polynova AG together with founder Renato R. Huebscher.
