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.”

Indorama Ventures exhibited the Trevira CS® brand together with 17 Trevira CS partner companies at the Heimtextil trade fair in Frankfurt, Germany, from January 14-17, 2025.

This year Trevira CS is celebrating its 45th anniversary! In 1980 Trevira CS® was launched on the market, at that time a pioneer for permanently flame retardant textiles whose flame retardant properties neither wash out nor are lost through ageing or use. They are characterized by the fact that they meet all essential fire protection standards without the need for a chemical finish. Fabrics made from specially produced flame-retardant polyester can be labeled as Trevira CS after passing a brand test. Samples, brochures, pictures and short anecdotes from 45 years of Trevira CS will be on display in a special area of the exhibition stand, inviting visitors to browse and smile.

In the anniversary year the focus of the Trevira CS® joint stand will be on permanent flame retardancy and the sustainability approaches of Trevira CS fabrics, which are known for their outstanding properties and versatility in the textile industry. Not only will the latest yarn and fabric developments from the 17 partners be presented, the three sustainability approaches from 1. pre-consumer recycling, 2. the Trevira CS take-back concept in cooperation with the company ALTEX Textil-Recycling GmbH & Co. KG in Gronau, Germany and 3. developments from chemically recycled raw material, but also all submissions to the Trevira CS Fabric Competition 2025. This encouraged Trevira CS participants to explore the interfaces between permanent flame retardancy, textile design, functionality and safety and to submit articles for five different categories.

The BREATHAIR® brand, a 3D upholstery material, was also be presented at the trade fair. This innovative and recyclable product has been specially developed for the upholstery industry and offers new possibilities for sustainable and comfortable furniture designs. Thanks to the nature of BREATHAIR®, it can be recycled at the end of its life cycle . Visitors to the trade fair will have the opportunity to experience the unique comfort of BREATHAIR® up close in a seating lab.

The Deja™ brand is an integral part of Indorama Ventures' commitment to long-term sustainability through recycling and bio-based materials. The product portfolio includes chips, as well as various staple fibers and filament yarns in multiple titer and yarn specifications.

In cooperation with Auping and TWE, Indorama Ventures and Deja™ developed an innovative mattress consisting of two basic components. This new design allows for easier disassembly and therefore more efficient recycling. The partnership aims to promote the circular economy and reduce the environmental impact of mattresses. By using recyclable materials and reducing waste, the companies are actively contributing to a more sustainable future.

The European Chemicals Agency’s (ECHA) investigation found that use of non-polymeric aromatic brominated flame-retardant additives pollutes the environment due to their persistence, bioaccumulation and toxicity. These substances are released to the environment throughout the product lifecycle, with waste stage being of particular concern.

ECHA has investigated, as requested by the European Commission, the uses and releases of aromatic brominated flame retardants (ABFRs), and their (potential) hazardous properties. It has also considered possible alternatives and aspects related to recycling and waste management.

The investigation focused on 60 ABFRs that are potentially on the EU market. The key findings are:

• Environmental impact
  Of all ABFRs, non-polymeric additives pose the highest environmental risks due to their tendency to leach from the material. ECHA identified five substances with particular concern, confirmed to be either persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB). In addition, 37 ABFRs are likely to be PBT. Of these, 17 are non-polymeric additives;
• Uses and releases
  ABFRs are used in many applications. The sectors contributing the most to the overall releases are electronics, construction and textiles. Releases from the waste stage are key contributors, particularly when materials are shredded or end up as landfill;
• Alternatives
  Alternatives to ABFRs are available for many uses. These include organophosphate flame retardants and non-combustible materials. However, some organophosphate flame retardants may have similar hazard properties as ABFRs and are prone to leaching. Polymeric ABFR additives are viable alternatives to non-polymeric ABFR additives in many uses;
• Waste management
  Inefficient recycling and waste management systems may increase environmental releases of ABFRs. To address the challenges, ECHA emphasises the need to eliminate problematic plastic additives early in the value chain; and
• Group approach
  Some non-polymeric additive ABFRs are not registered under REACH. Yet, they have been detected in the environment at high concentrations. This suggests potential issues with REACH registration compliance or uncertainty about the plastic composition in imported articles. Therefore, any regulatory action on ABFRs should consider a group approach.

This investigation will support the European Commission in deciding whether to request ECHA to prepare a restriction proposal and, if so, what its scope should be. A potential restriction on flame retardants is already included in the Commission’s planning document, the Restrictions Roadmap.

The Candidate List of substances of very high concern (SVHC) now contains 242 entries for chemicals that can harm people or the environment. Companies are responsible for managing the risks of these chemicals and giving customers and consumers information on their safe use.

ECHA’s Member State Committee confirmed the addition of triphenyl phosphate to the list in its October meeting. The substance has endocrine disrupting properties and is used as a flame retardant and as a plasticiser. The committee’s discussion on including the substance was originally foreseen for June but delayed, exceptionally, due to substantial new information becoming available on its properties.

Entry added to the Candidate List on 7 November 2024:

The list now contains 242 entries – some are groups of chemicals, so the overall number of impacted chemicals is higher.

This substance may be placed on the Authorisation List in the future. If a substance is on this list, companies cannot use it unless they apply for authorisation and the European Commission authorises its continued use.

 
Consequences of inclusion on the Candidate List
 
Under REACH, companies have legal obligations when their substance is included – either on its own, in mixtures or in articles – in the Candidate List.
 
If an article contains a Candidate List substance above a concentration of 0.1 % (weight by weight), suppliers have to give their customers and consumers information on how to use it safely. Consumers have the right to ask suppliers if the products they buy contain substances of very high concern.
 
Importers and producers of articles have to notify ECHA if their article contains a Candidate List substance within six months from the date it has been included in the list (07 November 2024).
 
EU and EEA suppliers of substances on the Candidate List, supplied either on their own or in mixtures, have to update the safety data sheet they provide to their customers.
 
Under the Waste Framework Directive, companies also must notify ECHA if the articles they produce contain substances of very high concern in a concentration above 0.1 % (weight by weight). This notification is published in ECHA’s database of substances of concern in products (SCIP).

As a leading company in workwear, flame retardant and defence and security fabrics, Carrington Textiles announced their commitment to sustainability by pledging exclusive support for the Better Cotton initiative with all our products containing cotton.

The announcement was made on the occasion of World Cotton Day on 7th October 2024, an ideal opportunity to highlight the commitment to developing workwear fabrics that not only offer high levels of quality and performance, but also support the production of responsibly sourced cotton globally.

Better Cotton is an initiative that promotes sustainable cotton farming practices to improve the environment and the livelihoods of farmers while ensuring high-quality cotton for consumers.
In 2019-2020, Better Cotton licensed over 2.4 million farmers from 23 countries across five continents. Together, these farmers produced 23% of the world’s cotton.

Better Cotton is sourced via a chain of custody model called mass balance. This means that Better Cotton is not physically traceable to end products, however, Better Cotton Farmers benefit from the demand for Better Cotton in equivalent volumes to those sourced.

When customers buy any of Carrington Textiles fabrics containing cotton, Better Cotton Credits or BCCUs are generated. These BCCUs can be claimed by a registered company directly on the Better Cotton Platform and used to communicate the responsibly source nature of the fabric’s cotton by using hang tags, labels and other marketing materials.

Neil Davey, Carrington Textiles' Managing Director, announced this commitment to sustainability reflecting the company's dedication to reducing its environmental footprint and providing customers with responsibly sourced materials.

Neil stated, "With 99% of fabrics from our FR, workwear and defence ranges containing cotton, this is a huge step towards our sustainability efforts, all of which we are proud to cover in our latest Sustainability Report. This initiative is expected to have a lasting positive impact on our products and the planet."

The second conference on flame retardancy will now take place in Berlin from 20-21 November 2024, organized by the AVK - Industrievereinigung Verstärkte Kunststoffe e. V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V.

In addition to the transport sector, the requirements in the construction/infrastructure sector will also be considered. Components made from fiber-reinforced plastics/composites that are manufactured for these sectors often have to have specific flame-retardant properties. Over the course of one and a half days, 14 presentations will provide information on new developments, requirements and innovations from the fields of standardization, material development, construction/infrastructure, public transport, automotive and research & science.

The lecture titles range from requirements and challenges for low-voltage products to the possibilities offered by new types of ceramifying fillers and flame retardants for e-mobility applications.

The event will be held in English.

Baldwin Technology Co. will join Elmatex GmbH at Techtexil (April 23-26 in Frankfurt, Germany) to demonstrate its TexCoat™ G4 precision spray finishing system.

With Baldwin’s system, the chemistry is precisely distributed across the textile surface and is applied only where it is required, on one or both sides of the fabric. The non-contact technology eliminates chemistry dilution in wet-on-wet processes, allowing full control of maintaining consistent chemistry coverage rates. Plus, pad bath contamination is eliminated, and changeovers are only required when there is a change of finish chemistry.
 
Furthermore, the system offers automated speed tracking, fabric-width compensation, and real-time monitoring to track system uptime, performance and chemistry usage, as well as active care alerts.
 
In addition, the TexCoat™ G4 system can process a wide range of low-viscosity water-based chemicals, such as durable water repellents, softeners, antimicrobials, flame retardants and more. Baldwin’s technology utilizes the same chemicals used in the traditional pad bath, and no special auxiliaries are required. The recipe is adjusted by increasing the concentration and reducing the pickup by a corresponding amount, so that the same level of solids is applied.
 
Some applications, such as durable water repellents, are only applied on the face of the fabric, instead of the traditional method of saturation through dipping and squeezing. Drier fabric entering the stenter means lower drying temperatures and faster process speeds. Single-side applications also open up the opportunity to process back-coated or laminated fabrics in a single pass of the stenter, instead of two passes.

Baldwin Technology Company Inc. will showcase its TexCoat™ G4 precision spray finishing system at ITMA Asia 2023 (November 19-23, National Exhibition and Convention Center, Shanghai). ITMA Asia participants can stop by and see Baldwin’s wide array of TexCoat G4-applied fabric samples from textile mills around the world and experience what precision finishing feels like while learning how the technology eliminates chemistry waste on changeover, saves water, and achieves faster speeds through the stenter frame and relaxed dryer.
 
Baldwin’s team will be available to discuss how the company’s technology can meet the textile supply chain’s sustainability and carbon footprint goals while improving performance and saving money. In the context of a cost-sensitive global economy and an increased focus by brands, consumers and regulatory agencies on sustainability, customers are placing a premium on sustainability-advantage textile production.

TexCoat G4’s non-contact spray technology offers numerous advantages compared to outdated finishing-chemistry application methods. TexCoat G4 processes a wide range of low-viscosity water-based chemicals, such as durable water-repellents –  including PFAS-free, softeners, anti-microbials, easy-care and flame retardants. The company's technology uses the same chemicals as found in traditional pad baths with no special auxiliaries required.

Testimonial videos from Pincroft Dyeing and Print Works and Graniteville Specialty Fabrics along with a video highlighting Baldwin’s partnership with North Carolina State University will also be screened at their stand.

Trevira CS is exhibiting for the first time at CSI Miami (Cruise Ship Interiors Design Expo Americas). Taking place on 6 – 7 June, 2023 at the Miami Beach Convention Center, CSI will bring together buyers and suppliers involved in cruise ship interiors, including interior designers, architects, outfitters, shipyards and suppliers.
 
On the Trevira CS stand, visitors can get an idea of the wide range of flame retardant fabrics suitable for use on board cruise ships. 53 fabrics from 20 Trevira CS customers will be on display that either have IMO certification and/or have been tested to the fire safety standards (FTP Code) required in the marine sector. Trevira CS fabrics are inherently flame retardant, meaning that their flame retardant properties cannot be washed out or lost through aging or use. This is due to the chemical structure of the polyester fiber: the flame retardant properties are firmly anchored in the fiber and cannot be altered by external influences. A surface-applied flame retardant finish is therefore not necessary.

In the marine sector, the demands placed on textiles are not only high in terms of fire protection, but also with regards to light resistance and durability. This is particularly true for textiles used in outdoor applications. These must be extremely robust, as they are exposed to moisture and sunlight. To meet these requirements, Trevira CS has launched a range of 30 new spun-dyed, UV-stable filament yarns. Besides color depth and durability, spun-dyed yarns offer another advantage: They are more sustainable because the fabrics made from them can be produced in a more environmentally friendly way than textiles that are dyed in one piece or consist of brightly colored yarns. In fabric production, a large share of resource consumption goes to the dyeing and finishing of fabrics as well as the use of chemicals and water. However, with spun-dyed yarns, these processing steps are unnecessary – the yarn immediately comes out of the spinneret in the desired color, reducing the products’ environmental impact.

The topic of sustainability is also taken up in other Trevira CS products. For example, Trevira CS fabrics are available in recycled versions. They consist of fiber and filament yarns obtained in different recycling processes. Filament yarns are produced using recycled PET bottles, they contain 50% post-consumer recycled material. Recycled fibers are obtained using an agglomeration plant and in further processing steps from residual pre-consumer waste from production. They consist of 100% recycled material (pre-consumer recycling). All flame retardant recycled Trevira® products are GRS (Global Recycled Standard) certified.
Fabrics made from these yarns are marked with the Trevira CS eco trademark. The prerequisite for this is a recycled content of at least 50%. Among the fabrics presented at the Trevira CS trade fair stand are 8 fabrics bearing the Trevira CS eco brand.

The long-term goal in developing sustainable products is undoubtedly to enter a circular economy. For this new path, an innovative Trevira CS product development was launched, producing flame retardant fibers and filament yarns from chemically recycled raw material. In this case, the basic raw material for the chemical recycling was PET bottles, but essentially it could be most any other PET recyclables, such as packaging material or even textiles. Chemical recycling involves depolymerization, a sequence of chemical reactions in which the polymer chains are broken down again into their original components, i. e. the monomers. In a further processing step, impurities are removed. Before the polymerization process is initiated, a small amount of MEG (mono ethylene glycol) is added.

The same technology used to produce the original (virgin) raw material for Trevira CS is also used here. The flame retardant modification is added during polymerization. In this way, the flame retardant properties are indelibly anchored in the polymer.

By recycling valuable materials such as packaging material, waste can be avoided. The raw material obtained from the recycling process is comparable to the original material can be used again in high-quality products.

Baldwin Technology Company Inc. will present its TexCoat™ G4 precision spray finishing system at ITMA 2023.

ITMA 2023 will be held June 8-14 at the Fiera Milano Rho Exhibition Centre (Milan). Baldwin will demonstrate TexCoat G4 as well as its Plasma Pure treater. ITMA participants can stop by and “touch” Baldwin’s wide array of TexCoat G4-applied fabric samples from textile mills around the world and experience what precision finishing “feels” like.  Experts will be on hand to discuss how Baldwin Technology can assist in transitioning the textile supply chain to reach their sustainability and carbon footprint goals while improving performance and saving money.

TexCoat G4 processes a wide range of low-viscosity water-based chemicals, such as durable water-repellants including PFAS-free, softeners, anti-microbials, easy-care and flame retardants, just to name a few. The company's technology uses the same chemicals as found in traditional pad baths with no special auxiliaries required.

In addition to TexCoat G4, Baldwin is offering its Plasma Pure treatment for textiles. The system enhanced and more efficient dyeing, coating and lamination of textiles and nonwovens. Its ceramic electrodes generate an air plasma used to efficiently treat the fabric surface. Key benefits include dramatically improved absorption and adhesion properties of the fabric, boosting productivity while enhancing the absorption properties with an optimized and uniform dyeing result and a significant acceleration of the absorption process. Laminated fabrics benefit from Plasma Pure technology with greater bonding strength.
