Nonwoven Protective Garments with Thermo-Regulating Properties

Abstract

Nonwoven protective garments possess a poor thermo-physiological wearing comfort due to their insufficient breathability. The problem can be solved by applying phase change material (PCM) to the fabrics that the garment consists of PCM is a highly-productive thermal storage medium, which can be used to absorb excessive heat released by the human body under strenuous activities. The heat absorption by the PCM results in a delay in the microclimate temperature increase and hence a substantial decrease of the skin's moisture release. Both lead to an overall enhancement of the thermo-physiological wearing comfort and a prevention of heat stress situations as a serious health risk. Furthermore, the wearing times of nonwoven protective garments can be extended, resulting in an increased productivity.
