Surface Thermal and Moisture Behavior of Wool Fabrics Treated with Hydrogen Peroxide

Understanding the surface comfort of wool fabrics with modified surface is essential for the application of wool. This work aims to reveal the surface wettability and the surface thermal and moisture behavior of wool fabrics modified by hydrogen peroxide with different concentrations. The water absorbing time and wetting area of the treated fabrics were recorded, and the wick heights were measured to understand the surface wettability of the modified wool fabrics. The thermal resistance and moisture resistance of the treated fabrics were tested, and the dynamic changes of the surface temperature and humidity were traced. It has found that the surface of treated wool fabrics become hydrophilic with enhanced wettability, and the thermal and moisture resistance are enhanced to some extent. Besides, the surface temperature of treated wool fabrics was higher while the relative humidity was lower than untreated in a dynamic moisture liberation process. The results suggested that the concentration of hydrogen peroxide has a significant impact on the surface wettability and thermal and moisture behavior of the treated wool fabrics. This work will provide insights on exploring the application of wool as wettable textiles, such as summer clothing and sportwear.
