The relationship between the adsorption of acid dyestuffs on nylon 6 fiber and the chemical structure was investigated by the use of following five kinds of dye; Dye (1) (C. I. Acid Orange 7), Dye (2) (Blue 45), Dye (3) (Blue 120), Dye (4) (Red 99), Dye (5) (Orange 45).<br>Three kinds of nylon 6 fiber which includes amino end group of 9.5×10-5, 5.4×10-4 or 2.5×10-5mol/g, were dyed at 90°C and at pH 3.5.<br>The result was as follows; the adsorption of Dye (1) which had small molecular weight and short molecular chain was completely equal to amino end-group content of the fiber.<br>The saturation of Dye (2) which had the same small molecular weight and short molecular chain as that of Dye (1), was 1/3-1/2 of amino end-group content of the fiber.<br>The saturation of Dye (3) and (5) which had large molecular weight and long molecular chain was lower than the end-group content.<br>The adsorption of Dye (4) which has large molecular weight and long chain showed H type curve.<br>Summary; it is confirmed that the adsorption of dyeson nylon 6 in equilibrium had no linear correlation with the molecular weight and chain length of dyes.
