Textiles play a crucial role in disrupting infections.

Dangerous pathogens such as antibiotic-resistant germs (MRSA) or various influenza and diarrhea pathogens (e.g. EHEC) are increasingly spreading. Hygiene management is essential for many industrial and service businesses.

Reduce risk with 3rd party certification.

Whether verifying antimicrobial effectiveness (against bacteria, yeasts, fungi and viruses) while considering sustainability and durability, comparing detergent effectiveness or monitoring industrial laundries, we work with customers to develop, test and certify textiles, products and processes according to application-specific requirements.

Testing for Hygiene Development and Verification

Application-focused and customized

Our customers include industrial laundries, textile and chemical manufacturers, health care facilities, brands, retailers and manufacturers of medical products, automotive and consumer goods.


Product Development

Tests to develop and objectively prove the efficacy and safety of functionalized products.

We examine materials, chemicals and finished goods in new condition and aged (used) condition by care treatment in household washing machines or in professional textile care.


Proof of Efficacy: Antimicrobial Textiles and Products

We research and test antimicrobial efficacy against bacteria, yeasts and molds or viruses
