Abstract
Abstract This invention is concerned with a dye carrier and a dyeing process which utilizes said dye carrier. The dye carrier and process are particularly suitable for use in the dyeing of synthetic organic fibers. More specifically this invention is concerned with a dye carrier and process for the dyeing of synthetic organic fibers of the hydrophobic type by the use of a dye carrier which generally comprises biphenyl, methylnaphthalene and an emulsifying agent.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
58 words
The carrier composition of claim 1 containing from about 25 to about 30 percent of biphenyl, from about 69 to about 65 percent of a coal tar distillate containing a substantial percentage of methylnaphthalene from about 2 to 3 percent of a nonionic wetting agent and from about 4 to about 6 percent of an anionic wetting agent.
Claim 2
Dependent Claim
45 words
The carrier composition of claim 1 containing about 25 percent biphenyl, about 69 percent of a coal tar distillate containing from about 40 to about 60 percent methylnaphthalene and 2 percent of a nonionic wetting agent and about 4 percent of an anionic wetting agent.
Claim 3
Dependent Claim
32 words
The composition of claim 1 wherein the wetting agent comprises a mixture of anionic and nonionic wetting agents wherein the ratio of anionic to nonionic wetting agents is about 2 to 1.
Claim 4
Dependent Claim
67 words
The carrier composition of claim 1 containing 35 percent biphenyl, 56 percent of a coal tar distillate which contains a substantial percentage of alpha and beta methylnaphthalene, 6 percent of an anionic wetting agent comprising the isopropyl amine salt of dodecyl benzene sulfonic acid and 3 percent of a nonionic wetting agent which is produced by the reaction of 36 moles of ethylene oxide with castor oil.
Claim 5
Dependent Claim
106 words
A dyeing process comprising the steps of: a. Applying a dyestuff dispersion in a suitable solvent to textile material b. adding a carrier formulation comprising from about 25 to about 40 percent of biphenyl, from about 69 to about 48 percent of coal tar distillate containing a substantial percentage of methylnaphthalene obtained by the distillation of coal tar at 230* to 250* C., and from about 6 to about 12 percent of a wetting agent, to said dyestuff dispersion; and c. applying heat to the carrier dyestuff dispersion of a period of time sufficient to cause the dye to penetrate into the fibers of the textile.
Claim 6
Dependent Claim
71 words
The dyeing process of claim 6 wherein the carrier formulation utilized comprises from about 25 to about 35 percent of biphenyl, from about 69 to about 53 percent of a coal tar distillate containing a substantial percentage of methylnaphthalene, from about 6 to about 12 percent of an emulsifier, and wherein from about 2 to about 15 percent of the carrier is utilized as based on the weight of the textile.
Claim 7
Dependent Claim
85 words
The dyeing process of claim 6 wherein the carrier formulation utilized comprises from about 25 to about 30 percent of biphenyl, from about 69 to about 65 percent of a coal tar distillate containing a substantial percentage of methylnaphthalene, from about 2 to about 3 percent of a nonionic wetting agent, from about 4 to about 6 percent of an anionic wetting agent, and wherein from about 7 to about 12 percent of the carrier is utilized as based on the weight of the textile.
Claim 8
Dependent Claim
67 words
The dyeing process of claim 6 wherein the carrier formulation utilized comprises about 25 percent biphenyl, about 69 percent of a coal tar distillate containing from about 40 to about 60 percent methylnaphthalene about 2 percent of a nonionic wetting agent and about 4 percent of an anionic wetting agent, and wherein 10 percent of the carrier is utilized as based on the weight of the textile.
Claim 9
Dependent Claim
89 words
The dyeing process of claim 6 wherein the carrier formulation utilized comprises 35 percent biphenyl, 56 percent of a coal tar distillate which contains a substantial percentage of alpha and beta methylnaphthalene, 6 percent of an anionic wetting agent comprising the isopropyl amine salt of dodecyl benzene sulfonic acid and 3 percent of a nonionic wetting agent wHich is produced by the reaction of 36 moles of ethylene oxide with castor oil and wherein 10 percent of the carrier is utilized as based on the weight of the textile.
