From the Sector

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.

Twelve companies from eight different countries will receive a JEC Innovation Award at JEC Asia 2018. Asia-Pacific is an innovative region that sets the tone for all other regions of the globe. Once again, the JEC Innovation Awards highlight how composites bring solutions considering the new challenges in terms of efficiency, sustainability and life-cycle analysis.

This year, JEC Group awards innovations in the following categories: aerospace (structural and tooling), automotive, commercial vehicles, e-mobility, marine, railway, sports & leisure, infrastructure & civil engineering, industrial equipment, sustainability and additive manufacturing.

The ceremony will take place on Thursday November 15, 2018 at the COEX Center of Seoul (South Korea). Ida DAUSSY (Seo Hye-na), will host the ceremony in front of officials, manufacturers, scientists and composites professionals.

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, will be presenting its innovative denim solutions for manufacturers and brands at DenimsandJeans India 2018, on August 1 & 2, in Bangalore, India.

Just two months after the DenimsandJeans Vietnam show, Archroma will again showcase its unique combination of technologies for denim effects and colors, from fiber to finish, from the authentic roots of indigo to the most innovative and eco-advanced solutions.

At the India show, Archroma’s expert team will also present its coatings and washing solutions aiming at bringing denim creativity to a whole new dimension.

DENISOL®, BRINGING INDIGO BACK TO ITS ROOTS - NOW ANILINE-FREE*
Archroma’s Denisol® range is a newly developed pre-reduced liquid indigo solution that is manufactured in Archroma’s award winning ‘zero liquid discharge’ manufacturing plant in Pakistan. Denisol® Indigo 30 liq is compliant with major official eco-standards and requirements from retailers, brands and fashion leading companies and helps to produce fabrics suitable for current eco-labeling such as bluesign® and GOTS.

Responding to demands for a non-toxic alternative to the dyes that are used for the iconic and traditional indigo blue that consumers associate with denim and jeans, Archroma just announced the upcoming new Denisol® Pure Indigo 30.

ADVANCED DENIM, TOWARDS WATERLESS DENIM DYEING
Consider this: The water needed to produce one pair of jeans is said to be ~ 11'000 liters(1). With approximately 167 million pairs of jeans produced monthly(2), that is 1,837,000,000,000 liters of water consumed every month in the process!
Based on the Denim-Ox and Pad/Sizing-Ox dyeing processes, Archroma’s multi-awarded ADVANCED DENIM, dyeing technology allows savings of up to 92% in water, 87% in cotton waste and 30% in energy, compared to a conventional denim dyeing process.

The technology has been adopted by brands like Patagonia and received the prestigious 2012 ICIS Innovation Award and Innovation with Best Environmental Benefit Award.
