Trumpler and Archroma launch tanning process for leather production

Trumpler has teamed up with Archroma to offer a leather production process that can be used to produce high-performance leather in a more eco-friendly and cost-efficient way.

The new process DyTan®combines offers an alternative to existing metal-free and chrome-tanned leather. It enables the reliable production of leather with great shavability, color depth and migration and abrasion resistance. Free from metal salts and reactive aldehydes, DyTan® is suitable for a wide range of leather applications, from garment and footwear to automotive and furniture upholstery, for today’s eco-conscious leather producers and consumers.

At the core of the DyTan® process is Archroma’s patented AVICUERO® System, which is based on novel molecules that enable more sustainable leather tanning and dyeing, developed by Archroma in cooperation with leather technology consultant Dr Leather. It enables collagen fibers in the leather to be covalently cross-linked through a simplified process at low temperatures. As a result, the system shows strong potential to save energy and water, while also reducing process time and CO2 emissions by up to 23%.*

The DyTan® process combines the AVICUERO® System with Trumpler’s bio-based fatliquors and retanning agents based on functional biopolymers produced from hydrolyzed shavings – resource-saving technology that Trumpler has been refining for 15 years.

As a global partner of Archroma, the Trumpler Group is responsible for the distribution of the AVICUERO® System worldwide. Delivering technical support and first-class customer care, Trumpler will help leather manufacturers and brands to implement sustainable tanning and draw on its comprehensive product portfolio and process knowledge of tanning, retanning and fatliquoring processes.
 

* Estimations carried out with the Archroma ONE WAY Impact Calculator show energy savings of up to 25% and reduced process time leading to a reduction in CO2 emissions of up to 23%, compared to traditional chrome tanning. They also show significant water savings compared to other metal-free tanning systems1. With the ONE WAY Impact Calculator, customers will be offered personalized calculations for their specific processes.

This new stitchbonding line will enable Romatex to better serve the growing customer requirements in terms of availability of high-quality products.

This will be the third line supplied by ANDRITZ to Romatex in four years. Helmut Höck, General Manager Operations at Romatex, says: “We bought our first line from ANDRITZ in 2017, then another one in 2019. We have been very satisfied with the close collaboration between our companies, the flexibility and reliability of the machines, as well as the excellent service from ANDRITZ over all these years. The experience has been uncomplicated. This has given us the confidence to consider ANDRITZ for a further investment.”

ANDRITZ is one of the global market leaders for supply of nonwoven production technologies, including batt forming equipment for the stitchbonding processes used to make Maliwatt, Malivlies and Multiknit. This segment addresses a variety of applications, including automotive, household, bedding, footwear, wipes, and many others.

Romatex is the leader in Maliwatt stitchbonding in Africa. Its facility is located in Cape Town. One of the company’s key strengths is its product diversification. Today, the company offers a complete range of bed linen, duvets, pillows, and stitchbonded products.

BASF invests in Chinese 3D printing specialist Prismlab

  • Unique, patented 3D printing process enables production of large-scale components
  • First direct investment by BASF Venture Capital in a company in China

BASF Venture Capital GmbH is investing in Prismlab, a leading provider of 3D printing processes and 3D printers, headquartered in Shanghai, China. Prismlab has developed a patented printing process that is characterized by a very high printing speed, high level of precision and lower printing costs. BASF’s venture investment will enable Prismlab to further accelerate its product development and innovation while strengthening its market reach to the global market.

“This is our first direct investment in a Chinese company,” said Markus Solibieda, Managing Director of BASF Venture Capital GmbH. “The trailblazing technology from Prismlab allows large and stable components, such as medical braces and anatomical models, to be 3D printed for the first time. This investment supports BASF’s strategy of actively advancing our technologies and expanding our product offering in the 3D printing sector.”

This investment supports BASF’s strategy of actively advancing our technologies and expanding our product offering in the 3D printing sector.”

“China is transforming from a manufacturing-driven to an innovation-driven economy. This investment in Prismlab reflects our commitment to further expanding our innovation capabilities in China, and BASF Venture Capital plays an important role in helping us identifying potential partners that lead us to success,” said Dr. Zheng Daqing, BASF’s Senior Vice President, Business and Market Development Greater China.

“The 3D printing technology must continue to evolve before it is set to change the world. At Prismlab, we aim to spearhead and accelerate that change by providing solutions through specialized customization. The investment allows us to stay laser-focused on our R&D capability, a key factor to achieve that goal,” said Mr. Hou Feng, Founder and Chairman of Prismlab.

Prismlab has developed a patented 3D printing process, “Pixel Resolution Enhanced Technology”, based on stereolithography (SLA). SLA allows comparatively large components to be produced using light-curing resins. Prismlab’s technology increases the printing resolution without compromising printing speed. In order to increase the amount of energy brought into a pixel, Prismlab’s technology divides each pixel in the resin into several small sections, which can be cured individually by exposure to LCD light. This makes the energy input into each pixel significantly higher than similar processes that expose each pixel to light once. This allows comparatively large and stable components or numerous parts to be printed in the same production step. With the use of LCD light, it also reduces process costs. This advantage opens opportunities in the footwear and furniture industry.

Along with this patented process, Prismlab also markets 3D printers and other related services. The Prismlab technology can be used in various key customer applications, including invisible braces, and anatomical models for medical, and education and training purposes.

SLA uses a laser for layer-by-layer curing of a photopolymer solution to shape the required workpiece. SLA and LCD based printing processes determinate the size, stability, and usability of the components to be produced as they are limited by the size of the light spot and the intensity of the light.
