Mixed polyacrylonitrile/cotton fabrics are dyed in a two-step one-bath process involving a first step in which the PAN fibres are dyed with basic dyes and a second step in which the cotton fibres are dyed with direct dyes, the second step being carried out at a lower temperature, at which the basic dyes used in the first step do not migrate. The resulting dyeings have good fastness properties which can be improved further by after treatment with certain fixing agents. |
