Dyeings (2% owf) were produced on conventional and microfibre nylon 6. 6 fabrics using unsulphonated, monosulphonated and disulphonated 1:2 metal complex acid dyes. When subjected to the ISO 105:C06/C2 wash test, the wash fastness behaviour of the dyeings was related to the degree of sulphonation of the dyes. Aftertreatment of the dyeings using a commercial syntan improved the wash fastness of the dyeings whereas the sequential application of a cationic compound to the syntanned dyeings caused a further improvement in wash fastness.
