Textile chemistry/finishing/functionalization
Plasma torch (left) and atmospheric pressure plasma plant (right) for the surface functionalization of yarns and textile 2D and 3D structures
The primary task of the textile chemistry/finishing/functionalization area is to research the basic relations between properties and effects in fiber materials, reagents, additives, reactive media, and reaction parameters. With modern finishing, coating, and treatment technologies, innovative and highly functional technical textiles are developed for a wide variety of applications, including energy generation, textile architecture, carbon concrete, medical textiles, conductive/sensor textiles or textile high-temperature protection. The core competences of the ITM in the field of textile chemistry/finishing/functionalization are:
- coating of yarns and textile 2D and 3D structures,
- surface functionalization of yarns and textile 2D and 3D structures,
- silvering of textile materials, and
- physical/chemical analytics.
These competences are used in a variety of developments.
Building material of the future – Textile concrete made in Dresden
Multifunctionally finished carbon fiber non-crimp fabrics with warp thread offset for textile concrete
The coating is a fundamental link in the seminal material referred to as textile concrete. To ensure a reliable bond between the mineral matrix and the fiber-based reinforcement component, new sizing and multifunctional coating systems are developed.
Metalizing synthetic and high-performance fibers
Ab ITM-developed wet-chemical metallization method for chemical fibers like polyethylene terephthalate and for high-performance fibers made from glass or para-aramid gives such filament yarns electrically conductive, electromagnetically shielding, sensory, microbicidal, or anti-inflammatory properties, which can be used for a number of applications.

Surface and interface design
Fiber material surfaces modified or functionalized based on chemical and physical methods display highly functional properties like repulsive/adhesive interactions, biological/biomedical activity, temperature-regulating behavior, and weather resistance. The methods used to achieve these are roughly classified as follows:
- wet-chemical methods for the pre-treatment, finishing and coating,
- corona/plasma technology for the treatment and functionalization of textile surfaces, and
- chemical surface activation and functionalization by means of chemical vapor treatment.
