Study of the dual mode mechanism of dyeing nylon with acid dyes, consisting of Langmuir‐type sorption on charged terminal amino groups, accompanied by Nernst‐type uptake, known as “overdyeing,” is subject to complications primarily (but not exclusively) because of structural nonhomogeneity of the po...
