From the Sector

The Saxon Textile Research Institute (STFI) will be presenting innovative highlights from research and development at Techtextil 2022, the international trade fair for technical textiles and nonwovens. In addition to a warp-knitted textile façade greening in a modular system and textile lightweight construction elements for the building sector made from hemp as a renewable raw material, the STFI will also be showing innovations from nonwovens research. The project optiformTEX is an example of the nonwovens competence: in this project, the mass per unit area was specifically influenced for the production of semi-finished products in the automotive sector. Furthermore, the Chemnitz Institute exhibits an ecological foam coating for protective textiles. Central highlight of the STFI's presence at the fair is also a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel.

Highlights at Techtextil 2022
The greened façade tile is a system with which large building surfaces can be cost-effectively greened through a simple, modular segment structure. In addition to insulating the building, the system has been created to meet the design requirements of a modern city centre; low-maintenance greening is made possible through functional integration in the textile carrier layer and coordinated plant selection.

Moulded components made of natural fibre nonwovens are increasingly used in the automotive sector. Conventional nonwovens currently have uniform masses per unit area. Technical solutions for load-oriented component reinforcement and the resulting optimised use of materials represent an enormous economic potential. The basic idea of “optiformTEX” was therefore to specifically influence the mass per unit area distribution in the pile before the semi-finished product is consolidated. As a result, a textile-technological process and the corresponding plant component were successfully developed.

Future-oriented materials are offered by developments from the field of renewable raw materials in combination with bio-based resin systems: In the “Gro-Coce” project, an innovative ceiling system was developed by combining sustainable building products and methods. Currently, a high-performance hemp-based semi-finished product as well as the steps for its reproducible production by means of textile surface formation is developed by the research team. Initial application and load tests of the hemp-based semi-finished products on wooden beams confirmed the high performance potential of the natural fibre materials.

Special functional textiles are based on composite materials with coatings or membranes. The previous production of the coatings/membranes poses ecological and health risks. At STFI, solvent-free, purely aqueous coating systems and a technology for their application were therefore developed for the protective textile sector, resulting in a breathable, waterproof and wash-resistant textile coating.

The central highlight of the STFI's presence at the fair is a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel. At the STFI, the robot is part of the “textile factory of the future”, where a play mat is woven and processed step by step along the textile chain.

Maruti Printing transformed its business as the first printer in India to adopt the latest LED-UV curing technology from AMS Spectral UV, a Baldwin Technology Company. The hybrid system, which includes traditional UV modules, has been in production for nearly two years and has significantly expanded the offset printer’s capabilities for its customers, including adding the ability to print on all types of plastic substrates.

Not only does Maruti have the distinction of being an LED-UV trailblazer in India, but it also is first in the market to upgrade a high-speed, high-performance Heidelberg Speed Master 72F+L six-color printer with coating tower—which prints up to 15,000 sheets per hour—with AMS Spectral UV’s high-power AMS XP9-I Series LED-UV and P3 Smart UV curing modules.

Established in 1986 and headquartered in Ahmedabad, Gujarat, Maruti serves customers throughout India, providing offset printing of scratch cards, banners, booklets, brochures, calendars, danglers, pamphlets, posters, stickers and envelopes.

In January 2020, Maruti took delivery of two AMS XP9-I Series LED-UV modules to cure colors in the interdecks. The modules are ideal for the highest-speed curing situations that require consistent peak intensity to the substrate, which is the case for Maruti’s offset printing standard of perfection with every cure.

To cure ink, as well as a growing variety of LED coatings, Baldwin’s AMS Spectral UV modules can be located after print units, or in the press delivery after the coater. When inks and coatings are cured with LED-UV, they become instantly dry via photopolymerization, allowing for printing on any substrate, including plastics and metallized stocks. Plus, work can be immediately finished and sent to the bindery once it comes off the press, without the need for heat, spray powder or drying time.

In addition, Maruti took delivery of two P3 Smart UV curing modules for installation at the end of the press to cure any type of UV coating and expand the company’s scope of coating compatibility to general UV coatings in order to offer its customers the widest range of UV printed choices in the Indian market.

The P3 Smart UV housings are completely liquid-cooled to ensure safe, consistent performance and increased uptime, and modules feature a universal design, so that any unit can fit any print unit location. P3 modules can be changed, inspected and cleaned quickly and easily, without tools, and lamps slide and lock into place smoothly and securely.

The durability of the equipment and its chipset was a critical deciding factor in India’s climate. The latest-generation power-and-control cabinets are dust- and moisture-resistant, allowing them to withstand extreme heat and humidity, as well as powder and airborne contaminants, making the equipment ideal for operation in stressful conditions anywhere in the world. AMS Spectral UV’s latest generation of LED chips, designed for the highest-intensity curing applications, enable the curing of LED inks and coatings at record-setting speeds. They are built with resilient components, and the semi-conductor components are sealed, which allows the chips to work in a variety of rugged environments. Additionally, integrated circuits incorporated into the design electronically protect the LEDs and the entire system.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

Monforts Head of Technical Textiles Jürgen Hanel will take part in the next international webtalk to be held by the VDMA’s textile machinery division on May 20th.

He will be joined by Johannes Lutz, Research and Development Engineer at Pleva, to provide full details of how the latest Monforts coating technology is supported by special microwave measuring systems.

The Montex®Coat magnetic roller coating option allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process.

“This roller provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater,” Hanel said.

Lutz will provide an overview of the use of Pleva microwave measurement technology in coating processes, in addition to the latest developments in electronic evaluation.

To ensure a constant high quality in coating operations it is necessary to accurately measure and control the amount of chemical being applied, and Pleva’s series 700 devices achieve this via contact-free microwave moisture measurement technology which can be supplied either as single- or three-point units, or as a traversing measurement unit.

The free-to-attend webtalk will take place on May 20th from 2-3pm (CEST) and registration can be made here, along with further information.

Flexibility, product uniformity and automation are the keys to success for coating businesses in today’s rapidly-changing technical textiles industry, explained Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.

Introducing the latest Montex®Coat magnetic roller coating option to virtual delegates from around the world at the conference organised by International Newsletters, Hanel explained why this technology makes perfect sense now

“The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” he said. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”

With traditional dip coating systems, he added, as well as with many standard knife coating technologies, there is always a difference in the tension between the centre and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 metres. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.

Cleaner and less wasteful
The contribution of such flexible and resource-saving new technologies to a cleaner and less wasteful textile industry was a key theme at the congress – held virtually across the four afternoons of February 11th, 12th, 18th and 19th – as was digitalization and the many advantages it is providing.

“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the Montex®Coat unit.”

Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.

The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fibre roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the Montex®Coat include the finishing of tents 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 accommodated.

“The World Congress on Textile Coating was characterised by some very stimulating presentations and forums between the speakers and a global audience of textile specialists,” Jürgen Hanel concluded. “It truly reflected the high level of positive changes now taking place in not just textile coating, but the entire textile industry. I look forward to the next edition, which hopefully will be a face-to-face event for even deeper level discussions and debate.”
