Abstract

Moisture Vapor Transport Through Fabrics

Human comfort in regards to clothing systems depends upon the ability of the fabrics and their construction to transmit perspiration away from the body. If the clothing system is inefficient in this regard, the wearer will experience a great deal of discomfort and physiological distress. It is critical, therefore, for the clothing to be "breathable" This project was an attempt to quantify the effect of environmental factors on the creation and transport of moisture/moisture vapor through different fabrics. The physics of the phenomenon will be described. The design and construction of a custom-made apparatus will be reported. The apparatus utilizes a controlled water heater, a humidity/temperature sensor, a fan, and a weighing scale. The results will be reported and discussed.
