Abstract:

Fabric staining with food items is an unfortunate, everyday occurrence. The development of stain resistant fabrics has been viewed as a solution to this dilemma. However, quantitative description and information on how food items stain fabrics remain largely unknown. In this study, the thermodynamic and equilibrium properties of how coffee binds on different fabrics were analysed. Gravimetric analysis was conducted which provided a quantitative description on how coffee adsorbs onto different cloths. The principles of adsorption were used to model the binding properties of the different components of coffee. A mathematical relationship was also derived which expressed how fabric surface hydrophobicity affects staining.
