nonwoven > knitted > woven and, in doing so, concurred with that of the two disperse dyes on the three types of PET fabric. The uptake of both disperse and direct dyes as a function of time was neither fibre- nor dye-related but was dependent upon some function of fabric construction. It was suggested that fundamental differences in fibre arrangement and porosity in woven, knitted and nonwoven fabrics resulted in differences in accessibility to dye molecules, according to which,
