Sorption isotherms for textile fabrics, foams and batting used in the indoor environment

• An increasing interest in the moisture buffering of indoor surface materials and new tools for calculation of energy demands and indoor climate calls for relevant material properties of all materials exposed to the indoor air. Textile fabric represents a large portion of the surface materials present in dwellings and offices and is therefore of special interest. This paper presents the sorption isotherms for nine fabrics, two foams and one batting, all of material compositions that are commonly found in the indoor environment. The data are fitted to the Hailwood-Horrobin sorption isotherm equation and good agreement is found for all materials. The difference in moisture capacity and hysteresis between different materials is discussed.
