Study on the moisture absorption and desorption properties of composite modified fiber-based humidity-controlling material
Uses fiber sheets with plant fibers as main components as the base material for humidity-controlling materials,and modifies the fiber sheets with the high hygroscopicity of inorganic salts to improve their humidity control capability.In order to reduce the loss of inorganic salts,a composite of super absorbent polymer and waterproof breathable film was used to modify the fiber sheets.Moisture absorption and desorption experiments were conducted on the raw materials and the composite fiber sheets in a constant temperature and humidity chamber,and the salt loss of the composite fiber sheet was tested.The experimental re-sults show that sodium chloride can enhance the moisture absorption performance of the fiber sheet,but the salt loss is signifi-cant.The composite of highly absorbent polymer and waterproof breathable film can effectively reduce the loss rate of inorganic salts in the fiber sheet.Among them,using a composite of highly absorbent polymer with the fiber sheets exhibits good humidity control performance,and the salt loss rate is small.
