Technical woven and knitted fabrics
Technical Equipment
For the production of textile surface and strand structures from threads, yarns or rovings, the STFI's machine park covers the most important manufacturing processes. Textiles can be woven, knitted, embroidered and braided. In addition, STFI's machinery offers in-house manufacturing techniques such as the Kemafil® process, a strand manufacturing process, or a diagonal (thread) guiding element with which multiaxial knitted structures suitable for stitch courses can be produced. Another component is the expansion or construction of special machines based on customer requirements.

Fields of application
Research News
Bioceramics
Instead of classical, non-degradable and thus durable implant materials, biomedicine is increasingly using bioresorbable materials enabling defect regeneration and supporting the body in self-healing. In the case of bone defects, calcium phosphate bioceramics are advantageous because their chemical composition is close to the mineral phase of the bone matrix – hydroxyapatite (HAP). Since bone tissue is highly anisotropic in structure, research is concentrating on the development of anisotropic bone substitute elements. The focus is on variably dimensionable implants with pore structures that not only allow ingrowth of cells and tissue, but also access by blood capillaries. The aim of this research project was to develop such an implant using textile technology processes.
Art and Technology
"KOMPLEMENTÄR"
"In her artistic works, Theresa has shown how wonderfully one can achieve completely new colour effects in the textile surface with only three different yarn colours. The variation of these yarns in arrangement density and layer makes interesting 3D knits possible. You do not need an infinite number of different coloured yarns to bring a great variety of colours into the surface."
Elke Thiele, Manager Technical woven and knitted fabrics at STFI
Under the title "KOMPLEMENTÄR" ("COMPLEMENTARY"), Theresa Kretsch carried out investigations of colour effects in interaction with the structures of knitted fabrics – the STFI supported her in this project. Theresa Kretsch dealt with the effects of the stitch pattern and the properties of the yarn on reflection, absorption and transmission of light in knitted fabrics. She found that the combination of construction-related effects (moire and traversing) with colour effects of complementary contrasts (increase of luminosity / grey formation / flickering) creates knitted fabrics with a holographic effect. The knitted fabrics form a new thematic field in textile design through the way they combine material, structure, effect and dimension.
