The Walter Sweating Fabric Manikin is a specialized mannequin used in the textile industry to test the thermal properties of fabrics. It is named after its inventor, Dr. Walter, and is designed to simulate the heat and moisture exchange between the human body and clothing.
The manikin consists of a full-sized human form made of aluminum, covered with a fabric layer that is tightly sealed to prevent air leakage. The manikin is equipped with sensors that measure temperature, humidity, and air velocity at various points on the body surface.
To test a fabric's thermal properties, the manikin is dressed in the fabric and placed in a controlled environment with specific temperature and humidity levels. The manikin's sensors then measure the amount of heat and moisture that pass through the fabric, providing data on the fabric's thermal insulation, breathability, and moisture management properties.
The Walter Sweating Fabric Manikin is widely used in the textile industry to develop and test new fabrics for a variety of applications, including sportswear, outdoor clothing, and protective gear. Its ability to accurately simulate human body heat and moisture exchange makes it an invaluable tool for fabric research and development.
It measures the amount of heat and moisture transferred through the fabric and evaluates the overall comfort level of the garment. This type of testing is important in industries such as firefighting, military, and outdoor sports where individuals are exposed to extreme temperatures and weather conditions.
