Lenzing Group, world market leader in specialty cellulosic fibers and Duratex, the largest producer of industrialized wood panels of the Southern Hemisphere, announce that they agreed on the terms and conditions to form a joint venture to investigate building the largest single line dissolving wood pulp (DWP) plant in the state of Minas Gerais, close to Sao Paulo, Brazil. This decision supports the backward integration and the growth in specialty fibers, defined in Lenzing’s corporate strategy sCore TEN.

The joint venture will investigate the construction of a 450,000 t DWP plant, which is expected to become the largest and most competitive single line DWP plant in the world. Dissolving wood pulp is the key raw material for the production of Lenzing’s bio-based fibers. For the future operation, the two companies have secured a plantation of 43,000 hectares that will provide the FSC® certified biomass. The plantation is fully in line with Lenzing’s wood and pulp sourcing policy. The basic engineering and the application for required permits and merger clearances will now be started.

Lenzing will hold 51 percent of the joint venture which will operate the mill, while Duratex’s share will be 49 percent. The estimated cash investment by the joint venture for the construction of the DWP mill is expected to be somewhat above USD 1 bn (based on current FX rates, net of generic tax refunds and the outcome of the basic engineering study). The joint venture will supply the entire volume of dissolving wood pulp to the Lenzing Group. This step is an essential milestone in the group’s ambition to grow its specialty fibers business.

“Specialty cellulosic fibers are an important contribution to make the global textile industry more sustainable. In line with our corporate strategy sCore TEN we are committed to strong organic growth in this field. We are pleased that with Duratex, a recognized leader in sustainable forestry management, we have a strong partner in this joint venture. Together we will create a very sustainable and competitive raw material base for Lenzing’s global expansion plans”, says Stefan Doboczky, Chief Executive Officer of Lenzing Group.

“Projects of this nature are the result of our strategic plan and of our team’s effort towards drawing Duratex’s future. The Company is known for its financial solidity, high quality, innovation and sustainability; the results of a history spanning over six decades. The partnership with Lenzing for the construction of the largest single line dissolving wood pulp plant in the world is an honor for Duratex. Working with Lenzing, a global benchmark in technology, high quality and corporate governance makes us very proud. We are sure that this joint venture is going to be successful”, affirms Duratex’s Chief Executive Officer Antonio Joaquim de Oliveira.

The final investment decision to build the dissolving wood pulp plant is subject to the outcome of the basic engineering studies and the approval by the respective supervisory boards.

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.

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.

In May 2017, Jochen Adler, Vice-President and Chief Technology Officer at Oerlikon Textile GmbH & Co. KG, presented a Oerlikon Barmag take-up winder as a partial gift to Prof. Dr Thomas Gries, head of the Institut für Textiltechnik (ITA) at RWTH Aachen University. The new Type ASW602 winder, which is equipped with modern control software and user interface, replaces the former institute’s Barmag take-up winder.


Due to this modernisation, ITA has access to a latest generation take-up winder which is used for various research projects. The new winder is applied at ITA’s two pilot melt spinning plants and ensures the transfer of new research and development insights into the pilot scale. Furthermore, this winder has two winding positions and operates with winding speeds between 2500 m/min and 5500 m/min. The new winder is suitable for all kinds of polymers, from polypropylene to polyethylene, polyester, polyamide etc. as well as for the production of several types of yarn, such as industrial yarn, pre-oriented yarn and fully-drawn yarn.
“We thank Oerlikon Barmag for the generous partial gifting and the support during the set-up of the new take-up winder”, says Prof. Dr Thomas Gries. “The new equipment will keep the institute’s machine park on a high and powerful level.” The head of ITA’s chemical fibre department Dr Thorsten Anders adds: “This winder is designed for the needs of chemical yarn research. It allows state of the art technology research and development and pilot-scale production. We will use it for the melt spinning plants in the single- and bi-component spinning process. This way, we can access a wide variety of producible yarn types.“
