The skin model can be used to simulate the production of heat and perspiration by human skin, in order to calculate various physiological criteria for a sample material. At present, the Hohenstein Institute is equipped with seven skin models in its own laboratories, while 20 additional devices made at the Hohenstein Institute are in service world-wide.

Because of the innovative construction of the hybrid yarn HP2G, knitwear made using it has particularly good thermal insulation properties while it also transports sweat away efficiently and dries quickly. This newly developed textile is also less prone to pilling. Fashion knitwear made from HP2G does not suffer from felting and looks as good as new even after being worn for a long time.

About 4,500 customers all around the world benefit from the expertise of the more than 500 employees who are either based at the headquarters in Bönnigheim (Germany), or in a global network of branch offices. Thanks to our expert local teams, we can offer you our wide-ranging portfolio of services to vary from textile testing to contract research in all the main textile producing and purchasing regions of the world.

Innovative workwear made from regenerated cellulose fibres combines various properties such as antimicrobial effect, high mechanical strength, a long service life, ease of care and good physiological functionality. As colour changes after washing and other external influences are excluded, it is also suitable for leasing.

The “skin temperatures” of the  human thermo-regulation model `Charlie’ can be regulated in 16 sections, allowing the measurement of the respective flows of heat. This makes possible varied assessments of thermal insulation in addition to the physiological function of a single garment, a sleeping bed or beddings.

Protective clothing for hot working environments should protect the wearer against damage to their health. By improving the thermophysiological properties and taking into consideration the underwear, wear comfort should also be improved in future.

By combining various materials, a high level of UV protection can be achieved for new types of workwear, while at the same time ensuring good wear comfort and considerable mechanical strength.
