An amazing connection
Founding the Deutsche Gerberschule
A standardised and fundamental vocational training for tanners and optimisation of technologies and materials for leather production were the main concerns when founding the Deutsche Gerberschule (German Tanner´s School) in 1889, as well as the Deutsche Versuchsanstalt für Lederindustrie (German Research Centre for the Leather Industry) in 1897, the predecessors of today's FILK.
Freiberg is located in the Erzgebirge (Ore Mountains). The montane region is characterised by mining. In this connection, leather played an important role: The rough material was needed for transport containers, drives, clothing and protective equipment - more than ever with commencing industrialisation. There used to be a lot of tanneries and factories in Freiberg area. Supported by the existing teaching and research culture of the well-established Bergakademie (mining academy) and the nearby Forstakademie (forest academy) in Tharandt, there was an ideal infrastructure in Freiberg for founding the Deutsche Gerberschule in 1889, which finally should ensure, standardise and further develop the quality of the vocational training of tanners.
Deutsche Versuchsanstalt für Lederindustrie Arises directly next to it
Years later in 1897, the Deutsche Versuchsanstalt für Lederindustrie opened in direct vicinity of the Deutsche Gerberschule; the task was to establish a scientific base for the tanning and leather trades in order to meet the requirements of the rapidly progressing industrialisation and the higher demands on the material leather by using more efficient technologies and developing new or better material properties.
With the establishment of synthetic polymers, the search for alternatives started
However, leather was and is available only in limited quantities. Compared to technical materials, the properties of leather can be adjusted only in a limited way, as it is a natural product. With the establishment of synthetic polymers, the search for alternative materials started, thus marking the beginning for the research and development of polymer coated substrates.
Today, both material groups are the focus of research and development
During the 1960s in Freiberg started the development of materials with leather-like properties, as the material to be substituted was best known here. An important part of the research work still focuses on the natural collagen and a selected range of synthetic polymers. Leather and coated textiles and products relating in application and properties would later become the object of innovative activities.

Nature Example Leather
It is unquestionable that leather is one of the oldest materials in human history. One could also argue that it is as old as mankind itself. Even though it has nearly vanished from most technical applications, the look-and-feel of leather as well as its excellent properties such as strength, softness, flexibility, and absorption of vapour capability and water vapour permeability are unique and make it an attractive material today, as it was then. It still plays an important role as either a protective or decorative material for the automotive, furniture, clothing and shoe industries.
With polymer chemistry prospering, the material was gradually substituted by coated textile substrates, an early example of the scientific field of bionics, even if this term was not known at that time. At times of developing industrial mass production, the aim was to produce cheaper materials in much larger quantities. The mid-20th century marks the start of imitating the properties of leather systematically.
Today, coated textiles are only one group of material among the wide range of polymer coated substrate. Their fields of application are just as versatile as their adjustable material properties. Modern composite materials are primarily arranged as multilayers and often have an additional function at the surface, such as electrical conductivity, antimicrobial effect, resistance to strains, or being flame resistant.
