From the Sector

The full potential of advanced coating and finishing technologies for the production of technical textiles will be outlined by Monforts specialists which takes place in Atlanta, Georgia, in May.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the VDMA German Pavilion at the show, at stand 3231 within the Georgia World Congress Center.

A wide range of technical fabrics is now being successfully created with MontexCoat coating units in comination with Montex stenters, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables.

Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be carried out with the extremely versatile system. Solvent coatings in explosion-proof conditions, knife coating, roller coating and screen printing are further options and the MontexCoat has been engineered to enable users to switch quickly from one fabric run to the next without compromising on the economical use of energy or raw materials.

“There has already been terrific interest in the MontexCoat and the range of different techniques it enables and we’re far from exhausting its potential uses,” says Achim Gesser, Monforts Area Sales Manager who will be at the show in Atlanta. “For companies who don’t need such flexibility, the economical coaTTex unit is exclusively dedicated to air knife and knife-over-roller coating.

“At our ATC in Mönchengladbach, Germany, however, a MontexCoat unit has been integrated into a full Montex technical textiles pilot line, on which our customers can run trials of new fabrics and finishing formulations in widths of up to 1.8 metres. This line has been engineered to provide the ultimate in precision coating and finishing in industrial-scale trials.”

To fully demonstrate what’s possible, the Montex line at the ATC is able to treat materials not only at temperatures of up to 320°C, but apply separate coatings on the two sides of certain materials at different temperatures, within a single pass through the machine. To achieve this, the first two chambers of the stenter are fitted with TwinTherm burners for individual top/bottom heating. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment parameters.

“There are many applications where employing two separate temperature treatments is beneficial, such as floorcoverings – where the textile face fabric is treated at one temperature and the rubber backing at another – as well as PVC flooring employing chemical foams, black-out roller blinds with heavy backings or PTFE-coated filter materials,” Gesser explains.

Another key feature of the technical textiles line at the ATC is the Montex stenter’s special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

Monforts also offers the special T-max grease-free stenter chain for high temperature treatments up to 320°C, at machine speeds up to 100m/min and transverse tension up to 2,500 N/m with the benefits of no maintenance and no grease marks on fabric.

“Technical textiles are extremely diverse in their end-use applications but the needs of the manufacturers of very different materials are still uniform in many respects,” says Gesser. “European-built Montex stenters provide maximum finishing efficiency and many of our customers are operating them 24 hours a day over seamless shifts.”

Existing customers include manufacturers in the fields of home textiles, geotextiles and automotive fabrics, as well as functional materials and dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics.

“Techtextil North America is a very important show for us because technical textiles are a key pillar of our production programme,” Gesser concludes. “North America is one of our major markets and we are looking forward to reconnecting with existing and potentially new customers at this always-vibrant show.”

On November 20th/21st, 2024, the second conference on flame retardancy for composite applications took place in Berlin, organised by the AVK - Industrievereinigung Verstärkte Kunststoffe e.V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V.

60 participants attended the international event, which this time focused on the requirements in the construction/infrastructure sector in addition to the transport sector.

In 14 presentations, 18 speakers provided information on new developments, requirements and innovations from the fields of standardisation, material development, construction/infrastructure, public transport, automotive and research & science.

Prof. Schartel from the Bundesanstalt für Materialforschung und –prüfung began with an introduction to the principle and concept of flame-retardant composites. In the following thematic blocks, the companies CTS Composite Technologie Systeme GmbH and Nabaltec AG provided information on new possibilities and developments at the material level of non-combustible fibre-reinforced plastics (FRP).

The implementation of fire protection requirements in the operation of rail vehicles or for load-bearing FRP components played a major role in the area of construction/infrastructure, as did the sustainability of these building materials, which Frank Lüders from DB Systemtechnik GmbH and Kabelan Thavayogarajah from Fraunhofer LBF reported on in their presentations.

The well-known topic of e-mobility took its place in the automotive sector, where Dr. Christian Battenberg from Clariant Plastics &Coatings (Deutschland) GmbH spoke about flame retardants for applications in this field.

The successful event was rounded off by the Research and Science block with two presentations by Fraunhofer LBF and Deutsches Textilforschungszentrum Nord-
West gGmbH & Centre for Nanointegration Duisburg-Essen.

Over the course of one and a half days, the conference provided an important platform for experts from industry and science to discuss the latest developments and challenges in the field of flame retardancy for composites. The high level of participation highlighted the relevance of the topic and underpinned the decision to organise a third round of the conference in 2026.

By establishing touchpoint textile, drupa has created a special forum to showcase pioneering applications in digital textile printing. The highlight will be the Digital Textile Micro Factory – a fully connected, integrated process chain starting with the customer enquiry and design through to large-format digital textile printing.

touchpoint textile represents drupa’s growing expansion into new markets comprising such segments as packaging production, large-format or industrial and functional printing next to packaging production. All of these segments are undergoing the same transformation processes and offer enormous growth potential. The special forum revolves around the opportunities and challenges of digital textile printing, brings together renowned exhibitors, industry partners and brand owners and provides scope for cross-industry cooperation, new projects as well as product and manufacturing ideas. The operational content partners of touchpoint textile include the German Institutes for Textile and Fibre Research Denkendorf (DITF), as Europe’s largest textile research centre, as well as ESMA, the European Specialist Printing Manufacturers Association.

Digital Textile Micro Factory: on-demand and virtual products – on the path towards sustainable production
In cooperation with 12 partners from industry and research the DITF will demonstrate a Digital Textile Micro Factory live at drupa and, hence, a fully connected, integrated process chain from design to finished product. This will present new possibilities for digitalisation and direct customer involvement, for instance in the form of 3D apparel simulations complete with links to design networks for creative input. Digital workflows and virtual products are integrated directly in the manufacturing process. As a special highlight for all trade visitors the technology partners of this Micro Factory will demonstrate an automated on-demand production, textile printing, cutting and sorting – without any manual interaction. Such decentralised and digitally connected design and production chains will enable the textile industry to respond to customers’ requests and trends in a more targeted manner in future. This means, touchpoint textile 2024 technologically points the way to a future without shelf-warmers. In addition, the carbon footprint for the complete process from virtual development to finished product will be modelled and presented at the trade fair.  

2024 will see the design competition “drupa – textile design talents” being held for the first time. This was conceived of by the DITF and will be implemented by the partner Mitwill. This provides up-coming textile designers and newcomers with a unique opportunity to introduce their ideas and visions to a professional audience.

Broad industry support
A project as comprehensive as the Micro Factory requires many strong partners. The companies “on board” here include: Assyst/Germany (3D simulation for digital apparel twins), Mitwill Textiles Europe/France (creative design network), D.G.I. Digital Graphics Incorporation/South Korea, Multi-Plot Europe/Germany (large-format textile printing), LEONHARD KURZ Stiftung/Germany, Zünd/Switzerland (digital cutting), robotfactory/Denmark, Asco/The Netherlands (presenting an innovative buffer solution between digital printing and cutting, automated sorting of cut parts from the cutter by robotfactory) as well as Brother/Japan (for small-format textile printing and bonding technology). Vaude and berger textiles will be sponsoring the touchpoint. Another key partner is the Albstadt-Sigmaringen University that is supporting the project as a conceptual sponsor and which has set itself the clear mission to incorporate these new topics into its curriculum. This means the staff of the future will be geared up to the new challenges ahead.

Another partner of touchpoint textile is the European Specialist Printing Manufacturers Association (ESMA), which is responsible for the lecture programme. ESMA represents industrial, functional and specialist printing and acts as an organiser of educational events in the field of textile printing. At drupa speakers from research, development, and industry will address issues related to printing and finishing techniques, workflows, market developments and sustainability, to name but a few. The focus will also be on trends and applications that unlock ever new potential through the interplay of digital printing and textile printing substrates. The lectures are divided into the categories Research, Finishing, Print Systems & Hardware, Substrates, Inks & Chemistry and Software & Electronics. Assyst, for example, will deliver talks on the virtual development of apparel as well as the research project ECOShoring, which is funded by the “Deutsche Bundesstiftung Umwelt” – DBU (German Federal Environmental Foundation) and focuses on personalised and on-demand sustainable manufacturing. Other speakers represent Adobe, Balta Group, Barbieri Electronic, Brother, Centexbel, CST, DITF, Fujifilm Speciality Ink Systems, HS Albsig, Kornit Digital, Meteor Inkjet, Mimaki, Mitwill, Multiplot, Print-Rite, RWTH Aachen, Seiko Instruments, Tiger Coatings, Xaar, Zünd and the list is updated on regular basis.

drupa will be held at the Düsseldorf Exhibition Centre from 28 May to 7 June 2024.

Graniteville Specialty Fabrics has set new standards by challenging the traditional pad finishing process. With Baldwin Technology’s spray finishing technology, Graniteville Specialty Fabrics has been able to increase production efficiency, and minimize chemical and water waste.
 
Based in Graniteville, South Carolina, Graniteville Specialty Fabrics produces coatings and coated fabrics that are resistant to water, fire, UV and weather for the military, marine and tent markets. The installation of Baldwin’s TexCoat™ G4 is part of a facility upgrade to maximize production efficiency and capacity in the durable water-repellent finishing and coating line to meet growing customer demand for advanced engineered products.

With sustainability benefits, tracking and process control, and Industry 4.0 integration, the TexCoat™ G4 provides high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. This system utilizes non-contact precision-spray technology, ensuring precise finishing coverage with the exact amount of chemistry. Changeovers (pad bath emptying, cleaning and refilling) are reduced, resulting in substantial chemical conservation and increased productivity.

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO₂ concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

Recreational boaters now have an easy way to be more sustainable following the introduction of a new biocide-free (B-Free) fouling control range from AkzoNobel’s Yacht Coatings business.

The first product to be launched from the new B-Free range is B-Free Explore. It features a specially-developed, unique silicone polymer technology which produces an exceptionally smooth and slick hull – helping to reduce drag.

Fouling is controlled by preventing microorganisms such as barnacles, slime and algae from forming strong bonds with the hull of the boat. Any that do adhere can be simply wiped away by hand or water jet.

“We’ve developed high-performance technology which allows boaters to maintain a clean, smooth hull,” explains Simon Parker, Director of AkzoNobel’s Marine and Protective Coatings business. “It’s based on proven technology and exemplifies the restless spirit of innovation which has been the cornerstone of our International brand for more than 140 years.”

Adds Jemma Lampkin, Global Commercial Director for AkzoNobel’s Yacht Coatings business: “Boaters are becoming more aware of the impact they can have on the environment, but they still require technologies that deliver high-performance fouling control. B-Free Explore provides a stand-out solution for both of these challenges.”

Specially crafted for the leisure boat market, B-Free Explore is the culmination of a five-year development program. It can be applied to new hulls or directly to existing antifouling, without the need for the removal of the previous antifouling coating. This makes it simple for boaters to upgrade from their traditional coatings to the new technology.

The new product is also better for the marine ecosystem. Being biocide-free, it provides a smooth surface for improved hull efficiencies, which can lead to a reduced carbon footprint.

Currently being introduced in Northern Europe, B-Free Explore will be rolled out across Germany, the Netherlands, Norway and Sweden in January 2023.

Baldwin Technology Company Inc. has announced the installation of its TexCoat G4 finishing system at Graniteville Specialty Fabrics, a recognized leader in the production of specialty coatings and coated fabrics. With Baldwin’s cost-efficient and highly sustainable spray finishing technology, Graniteville Specialty Fabrics has been able to increase production efficiency, and minimize chemical and water waste.

Based in Graniteville, South Carolina, Graniteville Specialty Fabrics produces coatings and coated fabrics that are resistant to water, fire, UV and weather for the military, marine and tent markets, and others. The company excels in developing and sourcing custom coatings, and creating specialized technical solutions to meet specific, and often unique, end-user requirements. The installation of Baldwin’s TexCoat G4 is part of a major facility upgrade to maximize production efficiency and capacity in the durable water-repellent finishing and coating line to meet growing customer demand for advanced engineered products.

With extensive sustainability benefits, unprecedented tracking and process control, and Industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. This system utilizes non-contact precision-spray technology, ensuring precise finishing coverage with the exact amount of chemistry for reaching the optimal performance of the fabric. Changeovers (pad bath emptying, cleaning and refilling) are significantly reduced, resulting in substantial chemical conservation and increased productivity.

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, 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.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.
