Abstract
The apparent diffusion coefficients D of three acid dyes (Acid Orange 7, Acid Blue 45, Acid Red 99) and one direct dye (Direct Blue 71) in Nylon 6 fiber were determined by the microscopic measurement of the distance of advancing front of dye from fiber surface (x).<br>The following results were obtained:<br>1. The method applied here was simple in process, but it needs a preliminary experiment before determining D because the method has narrow applicable range.<br>2. D from this method agreed with that of Hill' s equation, though K is variable with the kind of dyes.<br>3. It is supposed that the greater the molecular weight andthe nnmber of sulphonic acid group in dyes the larger K becomes.
