Hygiene with a capital H.

When it comes to hygienic cleanliness, textiles and their treatment play a decisive role. This is reason enough for Hohenstein to deal intensively with the subject area of applied hygiene. In the field of textile hygiene this includes, for example, the approximately 400 commercial laundries that are part of the German Certification Association Proper Linen Care e. V. (RAL-GZ 992), as well as our customers like numerous health care facilities and manufacturers of medical products, automotives and consumer goods or textile and chemical manufacturers.


We monitor microbiological conditions to commercial laundries, clinics, nursing homes, doctors’ offices, swimming pools and other areas. We check critical control points in your facility using the following methods:

  • Surface contact samples
  • Drinking and bathing water, process water, water from air conditioning systems for legionella bacteria testing
  • Testing with various bioindicators for washing machines, dishwashers and cleaning machines
  • Determination of airborne microorganism concentration and particle concentration in the air

We offer a wide range of tests to objectively prove the efficacy and safety of functionalized (textile) products. On request, we examine products in new condition and natural aged condition e.g. by care treatment in household washing machines or in professional textile care.

Proof of the efficacy of antimicrobial textiles and articles for domestic use

We study and test antimicrobial efficacy against bacteria, yeasts and molds or viruses according to DIN EN ISO 20743 or ISO 22196 (JIS Z 2801). Learn more.
