Abstract
Investigates the effects of moisture transfer on the compression properties and the volume change of wool, polyester and cotton futon padding by taking a series of creep measurements under three relative humidities and obtaining master creep curves from these curves at 20°C, 65 per cent RH. Discovers that the compression phenomena for wool, which absorbed the moisture from a drying state, were different from those obtained from desorption. Reveals that crimpy fibre assembly showed more volume change and better recovery than uncrimpy fibre assembly at high water content. Notes that the fibre crimp is also an important parameter for wool fibre assembly at high water content as well as standard condition.
