Offer

The institute is working as a non-profit research institution in the Free State of Saxony. Process-related and product-related research work covers classical textile technologies as well as innovative technical solutions for a wide range of applications.



At STFI, one important field is investigation into textile structures to reinforce plastic materials. Main application fields of such light-weight materials are aircraft construction, automotive industry and rail car construction.

A variety of machines are available:

* to lay threads into textile structures to reinforce plastic materials
* to process high-grade threads
* to vary fabric-related mass of thread required to withstand the strain in load direction
* to process hybrid ropes and yarns which contain both matrix and reinforcing components and could be transferred into fabrics and profile structures
* to produce fabric-type or ribbon-type structures to reinforce plastic materials and to adapt them to strain
* to vary the laying angle for producing multi-axial knits with up to 10 layers of reinforcing threads
* to develop inhomogeneous materials
* to achieve biaxial reinforced structures of high-grade threads

Future warp-knitting equipment is even expected to allow the production of reinforced structures showing local bulges. As well, profile-type or circular semi-finished products can be manufactured on warp-knitting machines. The accredited test department of STFI runs a laboratory to test semi-finished products of high-grade threads.


Research focus:
- recycling/textile waste (material cycle systems for textile-based mould parts, composites of one polymer type, technologies for reclaimed fiber manufacturing, quality assessment of reclaimed fibers)

- nonwovens/textile films, warp knitting, finishing/coating (technologies and pilot production of fiber nonwovens and spun bond nonwovens, mechanical and chemical-physical bonding methods, three-dimensional stitch-bonded nonwovens for lamination, filters, laminated composites, heat setting)

- textile materials research (light-emitting textiles for door interior linings and door sill cover plates, electromagnetic shielding by means of conductive nonwovens, heat exchanging seat)

- renewable materials/plant fibers (assessment of fibers, investigations on
production of yarn and nonwovens)

- Transfer Center Textile Technology



Competences and Primary Activities:

International competence in technical textiles – nonwovens – protective textiles based on the pillars, which include the Center of Excellence in Nonwovens, Innovation Center of Technical Textiles, Transfer Center and testing and certification services. In the future, STFI will dedicate itself to further specialised tasks in the research and development of technical textiles. In addition to this, the construction of all forms of lightweight textiles is one of our main goals, starting with CFRP semi-finished products to functionally-integrated and process-optimised
manufacturing processes based on textile technologies ranging up
to the development of new hybrid textile material composites. Recycling of processing waste as well as at the “end of life” of these new materials, partially intensive in costs, resources and energy, will become more important.

Key Research Activities:

• nonwoven technologies and technical textiles in the fields of mobile textiles, geotextiles, agrotextiles, ecotextiles, building textiles and lighting textiles as well as textile filters and protective textiles
• textile recycling and smart cycle waste management
• process optimisation on sewage and exhaust air emissions in the textile industry
• landscaping or recultivation of embankments and post-mine landscapes
