The Exothermic Effects of Textile Fibers during Changes in Environmental Humidity: A Comparison between ISO:16533 and Dynamic Hot Plate Test Method

The exothermic effects of high regain fiber types have been described before; yet, there not reliable tests to demonstrate these on the human body. Most test methods focus steady-state measurements; therefore, during changes in environmental humidity are typically analyzed or quantified. We conducted a set fabric that shows connection between effect water vapor uptake and its consequence for heat loss through transient conditions. performed ISO:16533 standard test, dynamic hot plate developed by Naylor measure property fabric, connect dots phenomenon. Although method tends show temperature increase fibers, it cannot differentiate hygroscopic (wool, viscose, cotton) (p > 0.001). In addition, sensor size sample folding techniques could impact increase. On other hand, showed greater difference release among (wool 20% higher than 50% more cotton), although relative chamber take time, which might reflect step-wise change humidity. So far, proven be most determining behavior textile fiber. However, still limitations simulate realistic conditions considering an instantaneous environment. This paper reflects comparison two recommends directions accurately address theory under
