The improved Walter Sweating Fabric Mannequin has been used to study the influence of walking motion on clothing insulation and evaporation resistance, including improved "walking motion" simulation, design and construction of automatic water supply, and real-time measurement by adjusting the pump inside the human body Evaporate water loss and regulate "skin" temperature. Tests on commercial clothing suits show that the measurement of clothing’s thermal insulation and moisture resistance has good repeatability, and the coefficient of variation is generally less than 5%. In addition to heat insulation and moisture resistance, the percentage of moisture accumulation in clothes is a very useful parameter to measure the comfort of clothes.

Sweating Fabric Manikin (Walter)(图1)

Full-body mannequin for enhanced clothing testing
Walter Sweating Fabric Manikin (Walter Sweating Fabric Mannequin) is designed in accordance with ASTM and ISO standards to meet the needs of clothing evaluation research. It provides data for users who research clothing and outdoor equipment. Although our standard 26-zone model meets general clothing or environmental testing needs, Walter can be customized for faster transient response, larger environmental range, or suitable for other research capabilities. In addition, the model can also choose the sweat system, fluid distribution system, reservoir and wicking fabric surface to provide greater flexibility in the test environment.



What's the price?
The new invention-Walter is inspired by the thermoregulation system of human body. With the original use of a breathable fabric to simulate the skin and a water circulation system to simulate the blood circulation, the novel manikin achieved perspiration over the entire body and very high measurement accuracy (viz. a CV of less 5%), yet with a cost of only a small fraction of other sweating manikins developed so far.
