Process for the level dyeing of polyacrylonitrile materials of slow, normal and rapid absorptive capacity |
| abstract |
Described is a process for the level dyeing of polyacrylonitrile materials, in which process there is used for dyeing polyacrylonitrile materials that have varying substantivity an aqueous dye liquor containing at least one migrating cationic dyestuff and electrolyte, as well as, optionally, at least one migrating cationic retarder and further additives. This process renders possible a level dyeing of all fibre types of polyacrylonitrile materials by one and the same dyeing method. Generally, no addition of a migrating cationic retarder is necessary. Only in the case of a light-colored dyeing is a very minor addition thereof required. Particularly suitable migrating cationic dyestuffs are those having a more or less delocalized positive charge, the cation weight of which dyestuffs is smaller than 310, the parachor smaller than 750 and the log P (relative lipophil property) smaller than 3.6. |
