ABSTRACT:
Textiles, especially polyester, nylon and high-tenacity nylon, are continuously dyed in an organic medium containing a high-boiling, nonionic solvent admixed with one or more lower-boiling organic solvents and at least one dyestuff dissolved in the solvent media. The lower-boiling solvent acts as a carrier to entrain the dye and allows the dye to enter the fiber evenly. The non-aqueous dyestuff medium allows the process to be conducted above the boiling point of water which facilitates dye penetration into the fiber and, in turn, shortens the dyeing process. Atmospheric pressure may be used, thus avoiding the constraints of a batch-type operation of pressurized dyeing procedures, as is conventionally used in this art. Fabric may be dyed in open width under restraint at elevated temperatures thereby achieving uniform coloring of the fabric without shade variations from end-to-end or "tailing". Dyeing the fabric at elevated temperatures with dimensional control allows the fabric to be heatset simultaneously with the dyeing.
