【Abstract】 The moisture absorption and thermal properties of hygroscopic exothermic fabrics were researched in this paper. Through the comparative test, the moisture absorption and thermal properties of the fabrics were tested. The difference in the hygroscopic exothermic performance between the fabrics and the commonly used fiber fabrics was discussed, and the hygroscopic exothermic effects and influence of the fabrics were evaluated. The results showed that fabrics can generate heat after moisture absorption,and some common fabrics also had the moisture absorption and thermal properties. Fabrics with excellent hygroscopic exothermicity had the characteristics of slow heating after hygroscopic and slow heat release. Fabrics with hygroscopic exothermicity can reduce the cold and wet stress reaction when moving from warm and dry environment to wet and cold environment to a certain extent. Hygroscopic exothermicity of fabrics were greatly affected by the content, area density and thickness of hydrophilic fibers in the fabrics.更多还原
