Dynamic water vapor sorption on lyocell and cotton fibers was gravimetrically investigated at 20 °C. Lyocell fiber showed a higher equilibrium moisture regain of 9.23% w/w at 60% relative humidity compared to 5.54% w/w for the cotton. The hysteresis between the sorption and desorption isotherms for...
