Having researched and tested interactions between humans, climate and textiles for more than 60 years, Hohenstein is a pioneer in developing scientific methods for material and product comfort. We know what matters for human perception and what to test – our WATson heat loss testing device is a DIN SPEC standard for quantifying the evaporative cooling of textiles.
Hohenstein is the world leader in assessing the comfort characteristics of materials, clothing, PPE, bedding, sleeping bags, car seats, furniture and more, used by material developers, manufacturers and brands for comfort optimization.
We investigate thermophysiological comfort:
- How effectively textiles or systems (ie. bedding or apparel systems) retain heat or cool down
- Whether materials are able to effectively transport sweat away from the skin and quickly release it into the environment
We have developed or modified specialized equipment to reliably determine the physical parameters of heat and moisture management. Moreover, we use climate chambers to simulate wear and climate conditions that are adjusted to the environment of use to test for specific application scenarios.
To measure wear comfort (also known as skin sensory wear comfort) we employ methods developed from scientific research to ojectively evaluate subjective sensitivity.
To what extent is wear comfort influenced by garment construction or fit and heat and moisture management? Using our thermal manikins and climate chambers, we determine the heat and moisture management parameters of entire clothing and textile systems - in the expected ambient conditions - during the potential user's movements.
For example, in personal protective equipment (PPE), comfort plays a key role in safety and user acceptance. PPE must be tailored to the needs of the wearer - while working in emergeny environments - and offer optimum comfort during all motion sequences.
The ergonomic comfort of clothing can be further optimized through body movement measurements from 3D scans and 3D data.
- Ongoing research and customized testing on the interaction between bodies, climate and textile materials and products (such as fabrics, clothing, PPE, bedding, sleeping bags, car seats, etc.)
- Quantitative measurement and quality control of individual parameters (heat and moisture management, cooling, skin comfort) for textile materials
- Determination of range of utility of clothing and personal protective equipment (PPE) based on clothing, climate and activity
- Assessment of comfort (heat and moisture management, wear comfort on the skin) of textile products
- Assessment of ergonomic comfort of clothing and consequences of pattern construction and design on wear comfort
- Assessment and advice for comfort-optimized textile materials and products
- Wear trials with human subjects in simulated ambient conditions and sensors for subjective and objective measurements
