  • Patent number: 4181499
    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.

  • Patent number: 4163642
    Abstract: An improved process is provided for the transfer printing of textile materials. In the process of this invention a heat sublimable dyestuff is printed onto a carrier sheet. The carrier sheet is then brought in contact with the textile material to be printed. Sufficient heat and pressure is applied for a suitable dwell time causing sublimation of at least a substantial portion of the dyestuff from the carrier sheet. The volatilized dyestuff is then transferred and deposited on the surface of the textile material to be printed. The carrier sheet is then separated from the textile material. The printed surface of the textile material is then heated to at least the sublimation temperature of the dyestuff in substantial absence of a convective gas flow, other than the volatilized dyestuff and maintained at this temperature until a given desired degree of resublimation and deposition of the dyestuff from the surface of the textile material to the interior of the textile material is obtained.
