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%.*

DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.
