From the Sector

Alchemie Technology, a leader in waterless, digital on-demand, smart dyeing technology, has today announced its partnership with HeiQ, a leader in textile innovation, as it prepares the production rollout of its NOVARATM digital multifunction finishing solution to the global textile market in Q3 this year.

NOVARA can apply single-sided, or simultaneous two-sided, coating of multiple finishes to specific areas of textile. For example, combining anti-odour and water repellence in one material.

“For example, using NOVARA for single-sided finishing of HeiQ Viroblock required 52% less chemistry, 66% water reduction and 50% less energy, whilst achieving a 99.7% reduction in antimicrobial activity after 15 washes at 400celsius. With the huge demand for high-performance antibacterial, antiviral finishing for face masks, medical apparel, gym wear, home furnishing, mattresses, and textiles for high-risk, high traffic areas such as train, plane seats, and more, our combined technology is critical for increasing protection and reducing environmental impact of these products” says Dr Simon Kew, Managing Director, Alchemie Technology.

NOVARA also enables unique lifestyle product innovations at lower production cost for fashion, sportswear, technical clothing, and upholstery such as combining sustainable odour control, skin care additives, and fragrance finishing, without impacting breathability, hand feel or wicking. It is suitable for finishing all fabric types, from 50 - 1000 gsm, including polyester, cotton, nylon and polycotton.

Devan Chemicals recently added two more products to its range of bio-based textile finishes. One being a softener, the other one a quick-dry finish. Both are derived from vegetable oils and are in line with the company’s latest innovations on bio-based chemistry.

Due to the Covid-pandemic, serving as an accelerator for a worldwide green economy, the textile industry is increasingly seeking more sustainable and products fit-for-circular programs. According to McKinsey & Company, the textile industry will experience innovation surrounding sustainably sourced raw materials and bio-based chemical additives to accommodate increasing consumer demand.

Devan launched its first bio-based technology in 2019 and is fully committed to making bio-based versions of their existing textile finishes. ‘We have put ourselves on a mission to be able to extend our Bio-Based range further”, says Sven Ghyselinck, CEO of Devan. “We wanted to make an even bigger impact on circularity than before, therefore we looked into what fabric producers use a lot: softeners and moisture management systems. Only by focusing more on the large volume products, can we support the industry to have a bigger impact on sustainability. After the growing success of our natural antimicrobial BI-OME NTL, we are proud to now introduce our new natural Passerelle line”.

Passerelle Soft NTL is a durable softness technology based on vegetable ingredients. The technology is wash durable and can be used with natural fibres like hemp, cotton, but is also fit for synthetic fibres like rPES, PA. The bio content of the technology is above 85% (ASTM D6866-20).

Passerelle Quick-Dry NTL is a moisture management technology also based on vegetable ingredients. This bio-based finish enables high wicking and evaporation capability which helps to evaporate water/sweat easier and faster. The technology is also > 60% (28 days) biodegradable according to OECD 301B.

Devan, one of the leading companies in sustainable and functional textile finishes, has been working together with Jeanologia, a global leader in sustainable and efficient finishing technologies for textiles, to reduce further water consumption during the application of Devan’s awarded BI-OME® antimicrobial and R-Vital® skincare range.

With increased attention to climate change and limiting excess water consumption in textile production (whether denim or other textiles), Devan and Jeanologia worked together to evaluate the application of Devan finishes onto garments via the patented e-Flow technology.

e-Flow technology can accomplish a considerable number of finishing effects with the highest quality, a minimal amount of water and zero discharge. The technology uses micronization and nebulization to substitute traditional abrasion process and deliver performance chemistry using nano-bubbles instead of water. It reduces the cost of application, saves the amount of water used and ensures that the correct amount of chemistry stays in the garment and not in the water. e-Flow is the perfect fit for every industrial washing machine. This allows mills and brands to apply Devan’s technologies in a more sustainable way than using traditional application equipment, even for smaller production runs and direct onto garments.

“With the global textile production using 4% of the global freshwater withdrawal, here at Devan we are continuously working on more sustainable solutions”, says Dr. Vanessa Daelman, CTO at Devan. “Next to this, we of course highly value sustainable application methods from Jeanologia, like e-Flow, in order to reduce the excess water usage during textile application. We are delighted that we could work together with Jeanologia and establish that Devan technologies can be easily applied via these technologies onto garments or fabrics like denim and with full retention of functionality. This application method also allows post garment treatment of our finishes, for example an antimicrobial treatment onto already finished garments, which will be increasingly important in a more circular textile world where re-use plays an important role”, Dr. Daelman concludes.

A decade long collaboration between Swiss textile innovator HeiQ and Spanish premium synthetic fiber manufacturer Nylstar, has resulted in the innovation of a revolutionary new premium antiviral and antimicrobial textile with zero pollution sustainable benefits, Meryl® Skinlife Force powered by HeiQ Viroblock Permanent, winner of ISPO Textrends Award for the Best Product.

The new technology is used exclusively on Meryl® Skinlife Force, an hi-tech fabric that combines the silver-ion active principle antimicrobial properties developed by HeiQ and Nylstar’s hydrogen-based technology which allows the creation of yarns with a very strong molecular cohesion structure. The Hydrogen molecular structure makes Meryl® Skinlife Force a high-performance fabric in terms of moisture management and breathability, offering a natural stretch without elastane as well as excellent durability thanks to its continuous and high tenacity filaments. The robust durability of HeiQ Viroblock Permanent is achieved thanks to the silver particles being added directly into the raw polymer of the yarn thereby keeping these properties active for the lifetime of garments. Fabric samples successfully demonstrated a very strong antimicrobial efficacy with over 99.99% reduction of both gram-positive and gram-negative bacteria after 100 washes. Antiviral test is underway.

Both HeiQ and Nylstar will be “exhibiting” at ISPO Munich Online from February 1st to 5th. Nylstar won the Textrends 2021 Award for the Best Product in the Base Layer Category.

Belgian textile innovator Devan Chemicals was lauded by Frost & Sullivan for its antimicrobial technology with proven quaternized silane chemistry, known under its trade name as BI-OME®.

RONSE, BELGIUM – The non-leaching attributes of the technology coupled with its ability to reduce microbial mutation make it a potential candidate for textiles where durability and safe human contact are highly valued.

Based on its recent analysis of the European antimicrobial technology for the textile market, Frost & Sullivan recognizes the Belgium-headquartered Devan Chemicals NV (Devan) with the 2020 European Technology Innovation Leadership Award. Devan’s highly relevant antimicrobial technology addresses issues concerning the contamination of PPE and textiles, including the spread of drug-resistant bacteria, viral transmissions, and hospital-acquired infections (HAIs). Its quat-silane technology, due to its non-migrating behaviour, physically punctures the microorganism cell to destroy it without interfering with cell DNA. Notably, it eliminates the adverse effects of leaching antimicrobials while providing high efficiency in the range of 99.9 percent to 99.99 percent, even after multiple washes.

"By providing non-migrating antimicrobial technology for the textile industry, Devan plugs the safety and performance gaps inherent in current inorganic and organic antimicrobial agents. Its antimicrobial technology, unlike silver- or triclosan-based technology, comprises non-migrating monomers and prepolymers such as organo-functional silane," said Monami Dey, Industry Manager, Frost & Sullivan. "The organo-silane polymers are covalently bonded and polymerized to the textile surface as a coating via padding, exhaust, and spraying techniques. The coating forms a non-leaching reactive surface and destroys the microbes on contact, without releasing harmful components into the environment."

Devan CEO Sven Ghyselinck is very happy with the award: “The best practice award is a nice recognition of the hard work we did in the last 6 months to evaluate the performance against viral activity. It’s great to see our efforts didn’t go unnoticed.”

Earlier this month Devan published new test results confirming the high performance virus-reducing capabilities of its BI-OME fabric coating technology on both unwashed and intensely washed fabrics. The Belgian company has worked closely with a series of international third party laboratories to test different fabric substrates against a wide range of enveloped viruses. Before washing, samples treated with Devan BI-OME score very good to excellent (99% and higher according to ISO 18184) results on virus reduction. Different substrates, like polyester, cotton and polycottons, were exposed to enveloped viruses like SARS-COV-2 (known to cause COVID-19), Feline Corona, Vaccinia (the EU standard for enveloped viruses) and Porcine Respiratory viruses. After 30minutes, BI-OME already reduced 99.96% of the activity of SARS-COV-2.

After washing, a decrease in virus reduction performance of coating technologies is normal and expected. However, BI-OME is confirmed to deliver only a minimal reduction, retaining up to 98.5% virus reduction even when the fabric is washed 25 times.

"Devan is working towards sustainability and green chemistry. For instance, its technology does not contain any harmful solvents such as formaldehyde or polychlorinated phenols and fulfills the regulatory obligations of the EU BPR," noted Dey. "Its commitment to promoting sustainability in textile finishes with a strong focus on GMO-free, kosher, as well as halal certifications, and recyclability has given the company an edge in launching new products at an accelerated pace to match customers’ most pressing concerns and demands."

One of those innovations is BI-OME NTL (natural), a natural, bio-based antimicrobial solution that guarantees an optimal freshness and hygiene for textiles. The active ingredient is the well-known Linseed oil, obtained from the dried, ripened seeds of the flax plant. The active ingredients in BI-OME NTL are GMO free, Halal, Kosher and recyclable.

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, has joined hands with Liberty Textile Mill Limited (Liberty), a leading producer in healthcare textiles to produce high quality personal protective equipment (PPE).

Liberty will be benefitting from Archroma’s specialty solutions for hygiene protection, and well-established technical expertise in the area of medical textiles. Amidst the COVID-19 pandemic, the PPEs manufactured by Liberty are aimed at easing the current shortage of PPEs for medical professionals in Pakistan.

Liberty carries over two decades of experience in medical textiles and exporting them all over the world. Its partnering with Archroma is a major step forward towards creating enhanced protection in the current crisis. With its advanced scientific knowledge and technical expertise, Archroma provides a complete set of specialty chemicals required to produce PPEs, in particular in the area of antimicrobial and barrier coatings. The project will assist in enhancing medical standards in hospitals, isolation centers and intensive care units, in Pakistan and, very soon, worldwide.

“By continuously challenging the status quo, we at Archroma are able to support our customers operating in or entering the area of medical textiles, with a holistic and expert approach to hygiene protection. With our collaboration with Liberty, we are so proud to be able to bring state-of-the art protection to health professionals and the general public,” comments Mujtaba Rahim, CEO of Archroma Pakistan.

“Liberty has a presence of more than five decades with high achieving accolades. Our processing units are fully equipped with latest equipment complying with international standards. We take this new partnership with Archroma as a start of building a strong relationship in the area of medical textiles. The COVID-19 pandemic has given a wake-up call to work extensively towards enhancing healthcare facilities. We are looking forward to new innovations in producing top-class PPEs,” adds Taimoor Mukaty, Director of Liberty Textile Mills Limited.

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.

Many SANITIZED customers particularly value the TecCenter for their development work in odor-management for textiles. SANITIZED offers an innovative product portfolio to meet this demand also including non-biocide additives.

• HeiQ Viroblock by CHT provides effective antiviral treatment on different fabrics
• No infective viruses left after 30 minutes
• For a wide range of protective textile applications

CHT is cooperating with HeiQ by implementing the HeiQ Viroblock by CHT in the textile industry, globally. HeiQ Viroblock by CHT is among the first textile technologies in the world to be proven effective against SARS-CoV-2 in the laboratory.

HeiQ Viroblock by CHT is a textile treatment for industrial use, designed to provide textiles with antiviral and antibacterial properties. The combination of silver antimicrobial technology and vesicle technology rapidly destroy enveloped viruses including coronaviruses. It has previously been tested against coronavirus 229E, another strain of virus in the Coronavirus family.

The latest testing with SARS-CoV-2 virus was conducted by researchers at the Doherty Institute, a joint venture between the University of Melbourne and The Royal Melbourne Hospital, an internationally renowned institution combining research, teaching, public health and reference laboratory services, diagnostic services and clinical care into infectious diseases and immunity. The research project involved a disinfection test protocol that simulated the real-life interaction of small aerosol droplets contaminating clothing. A known concentration of SARS-CoV-2 virus was contacted with the sample fabric for 30 minutes followed by measurement of remaining infectious SARS-CoV-2 viruses. The fabric sample treated with HeiQ Viroblock by CHT had no infective viruses left after 30 minutes. The result indicated a SARS-CoV-2 virus reduction of 99.99% relative to the inoculum control.
