Definitions

• theprior art has employed in the treatment of the hydrophobic,syntheticfibers elevated pressures with temperatures greater generally than 250 F.
• dyeingunder'pressure at'elevated temperature is undesirable duezto expensive and complex procedures.
• the prior art has also turned-to specific carrier components. These carriers aid in the penetration. of the dye into the fiber by causinga swelling of the base substrate.
• hydrophobic fibers allow satisfactory resultsattemperatures as low as 200 to 210 F although a temperature of 212 F at normal atmospheric pressure ispreferred.
• carrier components for hydrophobic fibers known in the prior art to be employed' with avariety ofdyes.
• typical carriers used by the art up to the present time are various derivatives of benzene and. phenol such as orthoand para-phenylphenol, chlorinated benzenes, xylenes, naphthalenes. toluenes, aromatic esters or ethers, and biphenyl. Nevertheless. many of these carrier components have some drawbacks such as lack of availability, undue toxicity, lack of ease of removal from the substrate, effect on lightfastness of color, or influence of buildup of a heavyshade.
• n is an integer from 0 to 3

• Thecarrier compounds of the present invention are, in most cases, clear colorlesssolids. They are utilized in the form of. an emulsion or dispersion composition which is added to the, dyebath formulation, printing paste, or prescouringbath. Besides the carrier activity they possess a bacteriostatic, action.
• the carriers of the present invention are generally colorless, odorless and non-toxic, or nearlyso. They usually do notgaffectthe fastness other than by improving it, and are either non-foaming or very low foaming. Dyeing processes utilizing, the carrier composition of the present invention exhibit a slow drawing of the dyestuff resulting in excellent levelness and extremely good. utilization or exhaustion of the dyestuff.
• dyestuffs employable in the present invention are well known in the art as disperse and cationicdyestuffs. Illustrative although not limiting of suitable disperse dyestuffs are those listed in the Color Index under the Disperse dye classification.
• a fabrous material includes fibers,,yarns, threads, fabric ribbons, tapes and tabs.
• Thedyestuff andemulsified carrier may be added to a bath at temperatureequivalent to the boiling point of water. A time interval of two or three hours is utilized during; which time the fibrous substrate is contacted with the dyebath composition. Thereafter the fabric is washed followed by drying.
• printing may be carried out in the usual way by adding the carrier emulsionto a paste and'printing the material on a roller or screen printing unit followed by fixing the dye by exposing to steamor. heat treatment.
• thermosol technique may be utilized by padding the material, with a mixture of a, disperse dye-emulsified carrier of the type disclosed herein followed by drying at to 250 C for l to 30 minutes. Alternatively thennofixing may take place with steam injection at temperature-time conditions as 340 F for l to 30 minutes.
