Huntsman Textile Effects introduces UNIVADINE® E3-3D

Huntsman Textile effects redefines dyeing of polyester including microfiber and blends with UNIVADINE® E3-3D diffusion accelerant
Eco-friendly diffusion accelerant provides reproducible, high-speed polyester dyeing

Singapore – Huntsman Textile Effects introduces UNIVADINE® E3-3D next-generation diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in an environment-friendly way that complies with current and anticipated industry sustainability standards.

The demand for polyester and man-made fibers is booming as sports and athleisure apparel markets expand rapidly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting pressure on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.

Developed by Huntsman Textile Effects specifically to meet these challenges, UNIVADINE® E3-3D diffusion accelerant is low-odor, free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution™ dyeing auxiliaries, it uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.

“UNIVADINE® E3-3D diffusion accelerant delivers across three key dimensions – diffusion, leveling and migration – for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects. “We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

UNIVADINE® E3-3D diffusion accelerant has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.

As a result of this cutting-edge diffusion technology, UNIVADINE® E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products. Reducing exposure to high heat, its Active Diffusion Technology minimizes the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The superior migration support of UNIVADINE® E3-3D diffusion accelerant also increases reproducibility, allowing mills to dispense with additional leveling agents. Polyester, microfibers and blends treated with UNIVADINE® E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by OEKO-TEX® and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products*.

Archroma breaks new ground with new aniline-free* indigo for denim

Archroma, a global leader in color and specialty chemicals, has presented an aniline-free* denim indigo dye at the recent Planet Textiles 2018 Conference in Vancouver, Canada. The brand new dye provides a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.
Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.

Scientific testing has shown that aniline impurities are toxic to humans, causing skin allergies, damage to major organs and genetic defects, as well as being linked to cancer. Aniline is also toxic to aquatic life, which is an issue as two thirds of the 400 metric tons of aniline waste on an annual basis ends up in the environment as wastewater discharge. The toxic chemical is therefore starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers. “We have tested denim garments and found that aniline concentrations are frequently higher than expected,” says Alexander Wessels, CEO, Archroma. “This could put some manufacturers over the limits agreed on their RSLs.”

True to its commitment to take on innovation challenges, Archroma decided to take a closer look at the issue with its R&D experts, and developed an alternative system that is aniline free*.
“At Archroma, we continuously challenge the status quo in the deep belief that we can make our industry sustainable,” continues Alexander Wessels. “By removing a hazardous impurity from the denim supply chain, we aim to protect the workers who create denim, the consumers who wear denim, and the environment with cleaner waterways.” The Denisol® Pure Indigo 30 dye is the latest in a long line of sustainable innovations for denim started in 2009. That year, Archroma introduced its ‘Advanced Denim’ technology which uses up to 90% less water during the dyeing process. “Being not indigo but sulfur based, ‘Advanced Denim’ itself was an aniline free solution too!”, adds Alexander Wessels. For designers and brand owners who long for authentic indigo inspiration, the new Denisol® Pure Indigo 30 now also makes it possible to produce indigo-dyed denim without high levels aniline impurities. Archroma successfully tested Denisol® Pure Indigo 30 at Absolute Denim mill in Thailand. “During the testing everything performed exactly the same as it would with conventional indigo,” says Vichai Phromvanich, Board Member, Absolute Denim. “There was just one important difference: no aniline.”

“We’ve had an overwhelming positive reaction from the industry in sneak previews and during the launch at Planet Textiles,” continues Alexander Wessels. “As a responsible industry leader, we believe it’s important to actively look for eco-advanced solutions that are attractive and at the same time cost-efficient for clothing brands, retailers and end-consumers.”

Archroma will make the Denisol® Pure Indigo 30 dye in the most sustainable way as possible. The new dye will be produced in Archroma’s facility in Pakistan, a plant that made the headlines in 2012 for being what Archroma believed to be the industry’s first zero liquid discharge plant.
