The work presented in this thesis is concerned with the nucleation and growth of calcium carbonate (CaCO₃). CaCO₃ deposition on fabrics during the washing process is a major problem, causing fabric damage and harshness. It is important to understand the mechanism of CaCO₃ nucleation in order to control its precipitation. The extent of crystallisation on different model fabrics was first investigated in order to understand the principal factors governing the crystal deposition. Surface topography of the fabrics such as the presence of steps and kinks was found to be the dominating factor for the nucleation of CaC0₃ crystals under the experimental conditions.
