Definitions

• a process of coloring a hydrophobic fiber with a dis perse or cationic dyestuff is disclosed using a dye carrier composition containing a carrier which is a solid at a temperature of at least 45C in conjunction with a compound of the formula:
• This invention concerns a dye carrier composition and the process utilizing such carrier composition for the coloring of synthetic hydrophobic fibers.
• Hydrophobic fibers such as polyethylene terephthalate, polyamides, cellulose triacetate, and the like however have been readily dyed with disperse dyestuffs. initially such dyeing was carried out under pressure at temperatures generally in excess of 250 F. Such conditions added greatly to the cost and complexity of the dyeing process because of the equipment which was required. These difficulties have been reduced by the utilization of dyeing auxiliariessknown as carriers which facilitate the penetration of the fiber by the dyestuff by causing a swelling of the fiber.
• hydrophobic fibers such as polyesters, like polyethylene terephthalate sold under. trademarks such as Dacron, Terylene and Fortrel, cellulose triacetates, polyamides and the like.
