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.

it takes only one step to measure the two most important parameters - thermal insulation and moisture vapour resistance. The arms and legs of “Walter” can be motorized to simulate walking motion. The perspiration rate can be regulated by changing the skin temperature and having a fabric skin of different moisture permeability. Since it mainly consists of water, it has a similar weight and heat capacity to a human body, which is also composed of mainly water.

Articulated joints and embedded components to increase usability

Walter Sweating Fabric Manikin is fully hinged and can be placed on the shoulders, elbows, hips, knees and ankles Provides various postures of movement. it providing complete equipment control, fault detection, data recording and analysis functions.

Adaptation standard:

-Nordic standards (eg INSTA 352-355)

-European standards (e.g. EN-511 2005, EN-13537 2002)

-American standards (such as ASTM-F1291 2005 and ASTM-F1720 1996)

-International standards (e.g. ISO-15831 2003)
