From the Sector

Archroma is showcasing its planet conscious innovations and solution systems at this year’s Colombiatex de Las Américas, being held from January 23 to 25, 2024.

Archroma is using its attendance at Colombiatex 2024 to introduce a new concept that promises to help the region’s brands and mills optimize their productivity, add value to their products and create a positive impact on the environment: Super Systems+.

The Super Systems+ solutions offer great performance, including end-product durability, while meeting sustainability targets with cleaner chemistries that comply with current and anticipated industry regulations or deliver resource savings, or both. Solutions are currently available for popular end-use segments, from denim to cotton and poly-cotton knits.

For black denim with a cleaner environmental footprint, brands and mills can choose DIRESUL® EVOLUTION BLACK to create unique shade and wash-down effects with an overall impact reduction of 57% compared to standard Sulfur Black 1 liquid.* For authentic blue denim, Archroma’s aniline-free** pre-reduced DENISOL® PURE INDIGO 30 LIQ produces coveted indigo colors with the same performance and efficiency as conventional indigo dye, but in a more planet-friendly way.

To embrace circularity and create natural shades on cellulosic-based fibers including cotton, kapok, linen and viscose, brand owners can now turn to Archroma’s patented EarthColors® technology. It makes high-performance biosynthetic dyes from non-edible natural waste, such as almond shells, bitter orange residues and cotton production byproducts, helping conserve natural resources. For next-generation processing of polyester and its blends, Archroma’s ERIOPON® E3-SAVE all-in-one auxiliary combines pre-scouring, dyeing and reduction clearing in a single bath to achieve substantial savings of water, energy and time.

For weather protection and stain resistance that is both economically and environmentally sustainable, Archroma Super Systems+ draw on an extensive portfolio of fluorine-free durable water repellents.

• BIONIC-FINISH®ECO Fluorine-Free, Water Repellent Finishes for Ultimate Performance

In recent years, many scientists have shifted from favoring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. Regardless what the real beginning really was, water was certainly involved in the process some 3,5bln years ago. And since then, Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by turning to those 3,5bln years of experience and by using natural design as springboard. That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Back in 2003, RUDOLF GROUP borrowed from Mother Nature the idea of dendrimers (from dendron, Greek word for ‘tree’), molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multicomponent systems. These hyper-branched polymers attach to the textile and embed fluorine-free, durable water-repellent performance.
In 2021 BIONIC-FINISH®ECO comes as a reviewed and extended family of unique nonhalogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs. Still very much based on patented dendrimer technology, the new and strengthened BIONIC-FINISH®ECO’s product portfolio:

• Provides non-fluorinated and highly durable water repellent textile finishes for high-performance, professional applications (e.g. when brushing resistance is required);
• Delivers highly efficient and durable performance with low application amounts thus not affecting fabric feel and appearance (e.g. when remarkable softness is important);
• Fulfills a range of challenging technical requirements (e.g. minimal impact on flame retardant properties of technical fibers);
• Is suitable for both sportswear and outdoor applications, as well as for casual apparel and fashion clothing;
• Is bluesign® approved, ZDHC chemical gateway certified and compliant with most RSLs;

BIONIC-FINISH®ECO new portfolio includes universal and versatile solutions targeting the most standard requirements, as well as customized solutions that meet more demanding and specific expectations such as improved resistance to dry-cleaning. “None of us can entirely predict where our voyage will lead” says Dr. Gunther Duschek, RUDOLF GROUP Managing Director. “However, BIONIC-FINISH®ECO of RUDOLF GROUP will always be the fluorine-free, durable water repellent for ultimate  performance. As it is today”.

The textile industry, one of the major industrial sectors worldwide, is going through a significant revolution, with changes taking place in various sections of textile processing. Biotechnology and biomimicry, for example, are continuously playing an important role in redefining the influence of the textile industry on society, and so is progress made in auxiliary chemistry, with advances investigated and then applied in almost every section of textile processing.  The outcome is amazingly promising.

Modern, real science is inextricably intertwined with environmental consciousness and they are definitely not mutually exclusive.

At RUDOLF GROUP modern, real science means pushing R&D so to constantly explore new technology and innovations that help transform the textile and fashion industries. We work to reduce the overall dependency on traditional and virgin resources.  Getting textile manufacturers as well as brand and retailers on board is key to achieve real change. By 2030 we aim for a significant fraction of our products to be either sourced through paths alternative to the traditional petrochemicals, or by upcycling waste and/or byproducts from other industries.

“This is the kind of genuine, tangible, environmental consciousness that truly defines us and that entails that RUDOLF GROUP has a responsibility for the needs of society as a whole.” Said Alberto De Conti, Head of Rudolf Fashion Division “We have a maniacal attention to the environmental impact of our operations and products. We have truly embedded in ourselves the notion that “sustainability” is a key issue and critical to the long-term survival of our company and of society at large. “

The combination of modern, real science and environmental consciousness leads to what RUDOLF GROUP call aspirational chemistry something unique and something that positions us as shining example and guiding light throughout the industry. That is, in fact, BETTER CHEMISTRY.

Two are the innovations rooted in aspirational chemistry that RUDOLF HUB1922 presents. The first one is our WASHLESS technology and the second one is a brand new launch: LASER SMOOTHER, which supports laser technology and helps creating much better denim looks.

WASHLESS

HUB1922 WASHLESS, which can be applied to both denim and non-denim, is the simultaneous application of
-    proprietary fluorine-free DWR (Durable Water Resistance) based on biomimicry to repel dirt
-    anti-microbial, anti-bacteria and anti-viral, non-migrating chemistry to stop body odour.
The combination of the 2 translates into garments that don’t require to be washed as much.

Life cycle assessment studies on clothes, detergents and washing machines show that home laundering is always the most energy‐demanding period during these products' life cycle, even higher than production or transportation phases.

“WASHLESS aims at changing consumer habits in clothing maintenance to a more environmentally friendly direction and represents a change that is the most feasible and efficient. Making washing machines obsolete is impossible, but even though the technologies in clothes cleaning have improved greatly, the washing frequency has not been reduced. We own more and more clothing and wash it more frequently. This increased amount of washing counteracts the technological improvements in home laundry. “ said De Conti.

It is only by understanding the climate change impact associated with home laundering that product innovations and consumer education can be explored. Studies consistently show that a carbon dioxide reduction of 105 MT and electricity savings of 142 thousand GWh can be obtained by reducing home laundering, on average, by 1/3. This is roughly equivalent to removing 12% of the 140 M passenger cars in the US, or taking 23 coal power plants off the grid. In addition, more than 60% of water consumed while laundering (2,000 billion liters) can be reduced through these strategies.

LASER SMOOTHER

Laser denim is the current dominant technology available to the denim industry to create locally abraded areas, vintage effects, whiskers, patterns, patches, and even intentional holes and tears in a garment. Laser technology uses less water, harmful chemicals (such as potassium permanganate) and energy to create a wide variety of denim looks.

However, laser is not always able to produce the desired look, on the desired fabric, in the desired time. Therefore, chemical companies have been developing laser boosters that can be pre-applied to the garments in order to intensify the effect of the laser to mimic heavier bleaching applications. Unfortunately, laser boosters can create blurred images where the definition is lower and the overall image less natural.

The brand new RUDOLF HUB1922 LASER SMOOTHER is an all-in-one formulation, very easy to pre-apply to garments before laser burning and that return a very natural image which is very similar to the highly desirable hand scraping. Laser smoother can be applied by traditional exhaust or through nebulization and it dries at normal temperature in normal tumble driers.  Advantages of LASER PRIMER are:

•    Remarkable enhancement of the fabric’s characteristics (heightening of material)
•    Overall effect much more natural and similar to manual scraping (craftsmanship dimension)
•    Reduced required laser power to achieve the wanted effect (conspicuous energy saving)
•    A faster laser burning process (significant time saving, depending on the final effect)
•    Any other chemical spray is not required (environmental friendliness)
•    Reduced cost compared to other solution (financial viability)
