A series of 8 dyes was prepared and used to dye nylon 6 and nylon 6,6. The interactions between dyes and methyl-p-cyclodextrin were studied by solubility isotherms, TGA and DTA analysis. Methyl-beta-cyclodextrin was examined as low environmental impact additive in dyeing processes. Methyl-beta-cyclodextrin showed good levelling properties on the dyeing of polyamide fibres. This effect can be due to the formation of complexes between methyl-beta-cyclodextrin and dyes.
