From the Sector

Sächsisches Textilforschungsinstitut e.V. (STFI) has been supporting companies in developing marketable innovations for over 30 years. With a clear focus on sustainability, the environment, health and protection, the STFI offers future-oriented research, textile testing for tailor-made solutions and certification of personal protective equipment. At Techtextil 2026, the institute will present ideas for the textile circular economy and showcase solutions for healthy and safe living.  

Highlights at Techtextil 2026: 
Sound booth – an oasis of calm amid the hustle and bustle of the trade fair 
Chemical recycling of mixed textile fractions produces textile residues that are currently not used as raw materials but are thermally recycled or disposed of. To enable further recycling, STFI is working with Refresh Global to investigate efficient treatment and processing methods for reusing these textile residues. These can be used in sound-absorbing design products, such as acoustic walls or furniture. Nonwoven forming processes are particularly suitable for processing these textile residues. At STFI, the recyclates are mechanically processed on pilot plants on a laboratory or semi-industrial scale before being laid into a non-woven fabric and consolidated. Through appropriate finishing, a visually matching top layer can also be integrated directly onto the nonwoven fabric. The finished nonwoven fabrics are processed into sound-absorbing design products by the project's industrial partner. 
 
Sports belt based on modulated medium frequencies for mobile applications for postnatal muscle building of the deep abdominal and pelvic floor muscles 
A team of companies and research institutions has developed a novel smart textile for stimulating and strengthening the deep abdominal and pelvic floor muscles using modulated medium frequencies (EMA), specifically for mobile use during and after childbirth. To this end, a textile belt was designed using knitting technology that covers the abdomen, thighs and buttocks and integrates electrodes at the relevant muscle zones. The electrodes are washable and fixed in the belt system, and the belt adapts to the user's decreasing body circumference thanks to its textile construction. The miniaturised, battery-powered control unit is attached to the belt and can be operated via a removable remote control. The system is easy to put on, comfortable, intuitive to use and does not restrict freedom of movement. This makes it particularly suitable for home use and everyday postnatal recovery.  
 
Protective trousers protect against stab and cut injuries and attacks by wild boar. 
In forestry and hunting in particular, workers are exposed to high risks of impact injuries resulting from attacks by wild boar. Conventional protective clothing often only offers protection against stab or cut injuries. The STFI has therefore developed a textile concept that adds impact protection to the existing level of protection, thus increasing the overall protection of users in practical working environments. In  tests, the impact of a blow was reduced by up to 20 per cent. We present an example of trousers in which the special impact protection fabric has been incorporated. Depending on requirements, the impact protection elements can also be designed to be recyclable. Specially woven hinges also increase the comfort of the work trousers.  

MC4 – Optimising recycling cycles for carbon and glass fibre composites 
High-performance fibre materials made of carbon and glass have a significant ecological footprint, and not just because of their energy-intensive production. High waste volumes in the manufacturing process and the reuse of raw materials at the end of the product life cycle offer enormous recycling potential for the future. MC4 (Multi-level Circular Process Chain for Carbon and Glass Fibre Composites) is a European project to promote circular approaches for carbon and glass fibre composites. These materials are indispensable in many technical applications due to their light weight and high mechanical properties. The project consortium is working until March 2025 to make the European value chains for carbon and glass fibres more ecologically and economically efficient and will present the development work carried out at the STFI stand as well as at its own stand and show what is technically feasible using selected demonstrators.
