The ideal 3d printing setting for innovative gloves

Protective gloves, such as those used for work, sport or household gardening, retrieve their protective function from a special coating. This coating provides abrasion resistance, makes the material waterproof and resistant to chemicals or oil, and even protects against cuts and punctures. Until now, coatings made of oil-based polymers, nitrile rubber or latex have been the main materials used. Using innovative technologies, scientists at the German Institutes of Textile and Fiber Research Denkendorf (DITF) have succeeded in developing a robust yet flexible glove coating using environmentally friendly lignin in a 3D printing process.

Coatings that are subject to mechanical stress always suffer from a certain degree of abrasion that is dispersed in the surrounding area. This is also the case with coated protective gloves.

In order to avoid long-term pollution of the environment, materials should be used whose abrasion particles are biodegradable. The aim of the research project was to improve conventional protective equipment and integrate more sustainable materials.

The biopolymer lignin is a natural component of plant cells that is produced in large quantities as a by-product of paper manufacturing. Due to its properties, it represents an environmentally friendly alternative to oil-based coating polymers.

The scientists developed biopolymer compounds containing lignin, which were used to produce thermoplastic materials that can be processed using 3D printing.

Lignin has few polar groups, which makes lignins hydrophobic and therefore insoluble in water. For this reason, they biodegrade slowly. This makes them particularly suitable for durable coating materials.

Despite this durability, lignin particles that are released into the environment through abrasion biodegrade faster than the abrasion of conventional coatings. This is due to the much higher surface/volume ratio.

The use of 3D printing makes it possible to produce the coating precisely and efficiently. The 3D printing process also makes it possible to adapt the glove to the individual needs of the wearer. This increases wearer comfort and promotes freedom of movement.

The research project shows that the use of lignin not only offers ecological benefits, but that protective gloves coated with it are also particularly durable and resistant. They meet safety standards and at the same time contribute to sustainability in the world of work.

The research project was funded by the Ministry of Rural Areas and Consumer Protection of the State of Baden-Württemberg as part of the Bioeconomy Innovation and Investment Program for Rural Areas "BIPL BW - Innovation" (funding reference BWIN220081).

More safety and comfort for protective clothing thanks to auxetic fabrics

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic structures behave differently here. They have the striking property of not changing under tensile stress or even increasing their width or thickness. These properties are advantageous, for example, in protective textiles or textile filter media. The DITF are researching auxetic fabrics for various applications.

Panty liners prevent bacterial vaginosis

Worldwide, almost one third of women of childbearing age suffer from bacterial vaginosis. This is when the sensitive microbiome of the vagina becomes unbalanced. Such a disorder of the vaginal flora can cause urogenital infections, abscesses on the ovaries or fallopian tubes or premature births. This significantly increases the risk of infertility in women and of contracting a sexually transmitted disease or HIV.

DITF send a signal for climate protection

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have successfully implemented extensive investments in photovoltaic systems at their site in Denkendorf. The systems installed on the roofs of the buildings and covered parking lots have a total installed capacity of 840 kilowatt peak (kWp). The DITF invested 1.6 million euros in this with the support of the state of Baden-Württemberg. The system was ceremonially put into operation on September 17, 2025.

4.2 million Euros for research into textile recycling

Around the world, used textiles are still rarely recycled and pile up into huge mountains of waste. A recent study by the Boston Consulting Group (BCG) drew attention to this problem. However, the low recycling rate is also due to the fact that only a small percentage of used textiles are actually suitable for recycling into high-quality materials and for demanding applications. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are addressing this problem with their research.

Award-winning research for sustainable carbon fibre cycles

Sustainable recycling of carbon fibres is possible through targeted electrochemical surface modification, which makes the sizing of carbon fibres resistant to solvolysis. ITA PhD student Sabina Dann was awarded the MSW Award from RWTH Aachen University for her master's thesis on this development. The award ceremony took place on 12 November 2025 in Aachen.

Kick-off for the Textile Production of the Future: Establishment of a Textile Technology and Development Centre in Mönchengladbach, Germany

The Institut für Textiltechnik (ITA) of RWTH Aachen University, together with its partners, is pleased to announce that it has received approval for its joint initiative, ‘Textile Factory 7.0’. The goal of the project is the establishment of a technology and development centre for the textile industry in Mönchengladbach.

Perfect quality through collaboration: Machinery from Trützschler, Toyota and Murata at Zirve Tekstil

In today’s textile industry, excellence is not achieved by chance – it’s the result of deliberate decisions, technical expertise, and the courage to go beyond conventional paths. The Turkish company Zirve Tekstil has done just that: by combining the best technologies from Trützschler, Toyota and Murata, they’ve created a production setup that delivers outstanding yarn quality – recognized worldwide.
