  • Patent number: 4227880
    Abstract: Described is a process for the production of solid dustfree preparations of water-soluble dyes and optical brighteners, which process comprises subjecting the pulverulent dyes or optical brighteners, together with a melt or a solution of ethylene carbonate or propylene carbonate, to a dynamic treatment. The preparations obtained have in particular the advantage that the dust-binding effect is retained undiminished over a long period of time, and that they are completely soluble when used in aqueous baths of dyes or optical brighteners.

  • Patent number: 4222742
    Abstract: The present invention is a dyeing and/or printing process which employs as an additive a composition comprising one or more cations selected from ammonium, Group I and Group II metals of the Periodic Tables due to Mendeleef, one or more carboxylate anions and water, the ratio of the anion to the cation being in the range of 2:1 and 4:1 on a chemical equivalent basis. The additive can be incorporated into the dyeing and/or printing process at various points in the process, for example at the stages of scouring of the fabric, mordanting, levelling, exhaustion, fixing finishing, water-proofing and milling. They are less corrosive to skin, clothing, plastics and metal and hence are safer to the operative and do not promote deterioration of equipment.
