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.
- x is an integer from 5 to 8, preferably 7;
- n isan integer from 6 to 8, preferably 7;
- Z is SO H, OSO H or the alkali salt sodium
- Y is H, OH, SO l-l, OSO H or the alkali salt thereof such as sodium;
- R is C,,H and n is an integer from 1 to 5, preferably 5
- n is an integer from 1 to 5, preferably 5
- a desirable example of the above compound is when xis7,mis7,ZisOSO l-I,YisHandnis5..
- the carrier composition is utilized in the form of an emulsion which is added to the dyebath formulation, printing paste or prescouring bath.
- the solid carrier will be employed at l0 to 92 parts by weight to 8 to 90 parts by weight of the disclosed constituent.
- the carrier composition various additives may be employed.
- a suitable example is a sulfated alkylphenoxy polyethylene oxide or sodium salt wherein the alkyl group contains 6 to 20 carbon atoms such as 6 to 15 carbon atoms.
- a desirable additive is the sodium salt of
- the carrier composition of the'present invention is useful in coloring fibers with both disperse and cationic dyestuffs. For example, it is especially useful in coloring acid modified polyethylene terephthalate (Dacron) with cationic dyestuffs.
- the carrier compound in the present composition will be a solid at normal room temperature and temperatures at least as high as 45 C.
- the term carrier is em ployed in its normal terminology in the art and enc0mpasses dyeing auxiliaries which facilitate the penetration of a hydrophobic fiber by a dyestuff by causing a.
- the dyestuffs contemplated in conjunction with carrier composition includes disperse or cationic types.
- Useful solid carrier components in the present disclosure include o-phenylphenol, biphenyl, phenyl benzoate, phenyl salicylate and napthalene.
- a desirable carrier composition containing this latter additive is a mixture containing to 50 to'90 parts by weight of the solidcarrier such as phenyl benzoate, 3 to 10 parts by weight of the disclosed constituent of the formula: I
- ll ZY CH3(CH2) disperse or cationic dyestuff and at a temperature and for a period of time sufficient to color the fiber.
- a preferred amount of carrier to employ is considered to be from 0.5 to 6 parts per parts of fiber by weight. Generally temperatures of 200 to 210. F will be employed. r
- fiber as used herein is meant to include filaments, bristles and fabrics and the like. it is not applicable to films and/or foils.
- the process of coloring as used herein is meant to include both printing and dyeing using all the usual methods employing carriers'familiar to those skilled in the art. Both roller printing and screen printing are therefore included as well as dyeing by the beck, jig, padder, and other well known dyeing methods.
- a dye carrier composition is prepared by emulsifying 70 parts by weight of phenylbenzoate with 13.5 parts of sodium oleylamylsulfate, parts of ethylene glycol and 1 1.5' parts of water.
- EXAMPLE 3 A printing paste is prepared containing 10 parts of the carrier compositiondescribedin Example l, 2.5 parts of a dyestuff of the formula:
- a dye carrier composition is prepared by emulsifying 65 parts by weight of biphenyl with 15 parts of sodium oleylbutylsulfate and 20 parts of water. 12 lbs. o f the emulsion thus formed are added to a dyebath at C containing 1.5 lbs. of the disperse dye of the formula:
- EXAMPLE 7 Fifty pounds of polyethylene terephthalate knitted fabric is prescoured at boilingtemperatures in a beck with a bath containing 6 percent by weight of the emulsion prepared in Example 6 for a period of 45 minutes. The scouring bath is removed, and the fabric rinsed with cold water. The fabric is then dyed in a bath containing 3 parts by weight of a disperse dyestuff of the formula:
- x is an integer from 5 to 8;
- m is an integer from 5 to 8;
- Z is SO H, OSO H, or the alkali salt thereof;
- Y is H, OH, SO H, OSO H or the alkali salt thereof;
- R is C I-l and n is an integer from I to 5.
- said solid carrier is selected from the group consisting of ophenylphenol, biphenyl, phenyl benzoate. phenyl salicylate, napthalene and mixtures thereof.
- said carrier composition contains between 10 to 20 parts of va sulfated alkylphenoxy polyethylene or sodium salt thereof wherein the alkyl group contains 6 to 20 carbon atoms.
- the carrier composition contains to 90 parts by weight of phenyl benzoate, 3 to 10. parts by weight of the amylester of the sodium salt of sulfonated oleic acid and 5 to 20 parts by weight of the sodium salt of sulfated nonylphenoxy poly (ethylenoxy) ethanol.
