Bio-based polyesters for challenging long-term applications

Current bio-based plastics are often only suitable for short-lived applications, such as packaging, because they have inadequate long-term properties. The new project “Bio-based polyesters for challenging long-term applications” from the Fraunhofer Institute for Structural Durability and System Reliability LBF aims to improve the long-term properties of bioplastics through targeted additivation in order to enable their use in technical applications. To do this, the researchers are looking for companies along the value chain that would also like to substitute petro-based plastics with bio-based solutions in long-lasting products.

In the planned project, bio-based materials will be optimized through targeted additivation to be comparable to petrochemical plastics. In numerous projects in recent years, researchers from the Fraunhofer Institute for Structural Durability and System Reliability LBF have conducted research in the field of plastic additives and can improve the long-term properties of plastics made from both fossil and renewable raw materials. The aim of the project is to replace petrochemical-based technical plastics in a sustainable way based on the knowledge gained so far in material optimization and to implement this along the entire value chain.

Minimal changes in the manufacturing process

The project addresses the challenges of the long-term properties of bioplastics. In a comprehensive literature review, existing data on long-term stability and the stabilizers used are first compiled. Together with the project partners, a specification sheet will be created that defines the material properties to be achieved. Market-available bioplastics and additives will be identified and tested for their properties. The modification of the bioplastics will be carried out by developing new formulations on a pilot plant scale. The aim is to enable material substitution with minimal changes to existing processing methods.

The Fraunhofer scientists are looking for partners from companies along the value chain, starting with manufacturers of plastics and additives, and including companies that want to substitute individual components in their designs, with a particular focus on developers and producers of finished components.

The use of novel additive systems should extend the life cycle of bio-based polyesters.

Securing competitive advantages together: sustainable, sophisticated plastic products

OEMs and manufacturers of plastic components in the construction, automotive, sports and leisure, electrical and electronics, and household appliance sectors who want to replace petrochemical-based plastics with bio-based solutions will gain sufficient knowledge to optimize their own research and development in a targeted and individualized way by participating in the new project “Bio-based polyesters for demanding long-term applications”. They will benefit directly from the latest findings, thereby securing competitive advantages. Raw material and additive manufacturers can expand their existing product portfolio with new applications, and compounders can prepare for future challenges in the use of bioplastics.

High-performance elastomers and plasma polymer coatings to replace fluoropolymers in technical applications: new Fraunhofer project

Users of poly- and perfluorinated alkyl compounds (PFAS), also known as "forever chemicals", are under pressure due to regulatory proposals from the European Chemicals Agency (ECHA). This also affects the use of fluoroelastomers, whose economic significance is enormous. Fraunhofer experts initiated the "HATE-Fluor" project at the beginning of February. Together, they want to develop high-performance elastomer compounds to replace fluoropolymers in certain technical applications.

Sustainable athletic wear made from bio-based Polyethylene

Conventional sports textiles made from petroleum-based synthetic fibres are to be replaced in the future by sustainable, bio-based, cooling textiles. Polyethylene, previously used mainly in the packaging industry, is thus qualified for use in textiles and, as a bio-based drop-in solution, offers a cost-effective, sustainable alternative for the future.

Innovation center for textile circular economy inaugurated

Just over eight months after the foundation stone was laid, the new Innovation Center for Textile Circular Economy was officially inaugurated today at TITK Rudolstadt. Thuringia's Minister President Mario Voigt, TITK Director Benjamin Redlingshöfer, and other guests of honor cut the ribbon to the modern building complex and viewed the premises, which are now ready for occupancy. The “DICE – Demonstration and Innovation Center for Textile Circular Economy” is TITK's largest single investment to date. The Free State of Thuringia supported the total cost of €11.5 million with €8 million in GRW and FTI funding.

Sustainable design of Geosynthetics and roof underlayments made from recyclates

Is it possible to recover plastic recyclates from previously unused waste streams in order to produce high-quality fibers and films? How can bio-based polymer fibers be manufactured so as to allow adjustable biodegradability? These are the questions being addressed by researchers from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in the Zirk-Tex project.

MUNICH FABRIC START: Between Attitude and Sensuality

The future begins where we reimagine it. After seasons of restraint, Spring.Summer 27 marks a conscious counter-trend: optimism, sensuality, and creative freedom are replacing pragmatism and neutrality. Physical presence and individuality are regaining importance – as a response to uncertainty, exhaustion, and algorithmic predictability. The overarching theme of PLEASURE stands for fashion as an emotional space, as an expression of attitude and cultural reflection. Colours, surfaces, and materials become vehicles for self-confidence and joie de vivre.

organIQ seek: smart alternative to potassium permanganate

CHT Group announces new technical findings within its organIQ seek platform that significantly advance the transition toward permanganate-free denim bleaching. Through extensive industrial testing and application research, CHT confirms that organIQ seek can now be used with remarkable effectiveness as a substitute for potassium permanganate in spray bleach, while remaining aligned with sustainability expectations and cost realities in the European market. At the COLOMBIATEX in Medellín as well as at the Exintex in Puebla and the Kingpins Show in Amsterdam the CHT Group will present organIQ seek as an alternative to potassium permanganate.

PERFORMANCE DAYS: Focus topic shifts to the beginning of the value chain

Following the last Focus Topic in October 2025, which placed Textile-to-Textile Recycling at its core, PERFORMANCE DAYS continues to drive the conversation around circularity – this time with an expanded and more upstream perspective. The upcoming Focus Topic, “Textile to Textile: The Role of Collectors and Sorters,” presented during the spring edition on March 18–19, will spotlight one of the most essential yet often overlooked components of a functioning circular textile system: the efficient collection and sorting of post-consumer textiles.

Proven performance, optimised costs – the new RE 6 EL

Nowadays textile companies increasingly need to produce small production runs and respond to market changes with instantaneous pattern changes in order to operate profitably – meaning they require machines that offer maximum flexibility, reliability and cost efficiency. KARL MAYER understands the challenges of the market and is launching its new RE 6 EL. The Raschel machine offers the core strengths of the classic RSE 6 EL and essentially the same performance parameters, but has been further cost-optimised largely due to local production advantages. This makes the newcomer an efficiency champion in production, especially when it comes to frequent pattern changes.
