NON-AQUEOUS PROCESS FOR THE DYEING OF DYEABLE MATERIALS AT AN ELEVATED TEMPERATURE IN A NON- REACTIVE ENVIRONMENT

摘要

ABSTRACTThe present invention provides a non-aqueous process for thedyeing of a dyeable material at an elevated temperature by con-tacting a dyeable material with a dye composition at an elevatedtemperature in a non-reactive environment. The dye compositiontemperature and the time of contact between the dye compositionand the dyeable material are sufficient to effectuate the dyeingof the material. The dye composition comprises a substantiallynon-aqueous solvent and a dyestuff.
