Technical woven and

Knitted fabrics


Competence brochure
Technical woven and knitted fabrics

Technical textiles are used in almost every area of our daily life-, for example in the automotive, sports and medical industries, in the agricultural and geotextile sectors, in protective equipment and other fields of application. Innovative woven and knitted fabrics make a major contribution here, with properties individually adapted to the task in hand. Our team of scientists and technicians develops new and innovative solutions for the demands placed on technical woven and knitted fabrics, both in publicly funded projects and on behalf of our partners. Starting with the selection of suitable materials as well as textile technologies, over the development of the textile construction up to the production of prototypes, we are at your disposal.

We are looking forward to your exciting tasks, technical discussions as well as a goal-oriented technical cooperation with you.

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.

"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.

Car Park


01/2020–06/2022

Weather extremes, such as heavy snowfall in winter, freezing rain or very rapid temperature drops into the frostrange with simultaneously wet surfaces, require the use of expensive and environmentally harmful de-icing salts in order to fulfill the obligation to maintain road safety, which in turn promote chloride impact in the reinforced concrete component and lead to reinforcement corrosion. The use of a surface heating system is obvious here, but is bound to clear limitations in the reinforced concrete component. As a result, the application of these systems results in very long heating and reaction times. Thus, panel heating is not able to react quickly to weather extremes. Due to their material characteristics, non-metallic reinforcements made of carbon fibres (carbon fibres) are an alternative, since they themselves constitute the reinforcement and, due to their high corrosion resistance, can be installed close to the surface. Therefore, a multifunctional solution approach using glass/carbon reinforcements is chosen in the Car Park research project.
