    Abstract: The present invention relates to a process for producing dyed polyester fibers (C) from a terephthalate polyester (A), at least one polyester-containing additive (B) and optionally at least one component (G). The polyester-containing additive is obtainable by condensation of the monomers of an aliphatic 1,?-diol, of an aliphatic 1,?-dicarboxylic acid and of an aromatic 1,?-dicarboxylic acid. Optionally, chain extenders (V) are also used in the production of the polyester-containing additive (B). For fiber production, the components (A), (B) and optionally (G) are mixed, melted in an extruder and extruded through spinneret dies.

An ethoxylated alkylphenol and other surface-active constituents selected from the group comprising sodium dioctylsulfosuccinate, sodium benzoate, fatty acid condensates, phosphoric ester and alkylpolyalkoxylate may be added to the vehicle. This dispersion compatible with conventional polymers permits obtaining products of a homogeneous coloration, without surface alteration and without distortions.

  • Patent number: 4985041
    Abstract: Compositions for use as dye assistants are formed from a non-phenolic aromatic swelling agent for the fiber to be dyed mixed with just enough dispersant to cause a non-foaming emulsion upon dilution of the dye assistant in water, but not enough dispersant to interfere with the swelling process of the fiber by the dye assistant. Thus, the swelling agent is mixed with the minimum amount of surfactant required for the production of an emulsion and dispersion of the dye with little or no foaming in the dye bath. Formulations can also be prepared having higher levels of water which are non-flammable.

  • Patent number: 4710200
    Abstract: Continuous dyeing of poly(m-phenyleneisophthalamide) fibers using a swelling agent to introduce a dye into the fiber. The dyed fiber has properties of strength and fire retardance approximating the original undyed fiber and is conveniently dyed to an unlimited range of colors with high color yield and relatively good lightfastness at a resonable cost. An aqueous dimethylsulfoxide solution is used as the swelling agent.

  • Patent number: 4272244
    Abstract: A process for dyeing without shrinkage with a disperse dyestuff or an optical brightening agent a fibrous substrate whose fibres comprise a mixture of polyvinyl chloride and acetalized polyvinyl alcohol, in which the substrate is dyed at a temperature from 60.degree. to 90.degree. C. in the presence of a levelling carrier, this levelling carrier being removable when the dried substrate is subsequently submitted to a dry heat treatment for a period up to 120 seconds and at a temperature from 95.degree. to 135.degree. C.

  • Patent number: 4252534
    Abstract: A dyeing assistat containing at least(a) an alkylbenzene or tetrahydronaphthalene (tetralin) or a mixture thereof,(b) an anionic surfactant,(c) a non-aromatic and water-immiscible solvent and optionally also(d) a polar solvent and/or(e) a non-ionic surfactant; this dyeing assistant can be used to promote the migration of the dyes and thus to improve the levelness and dye yield when dyeing synthetic fibre material, preferably polyester, in particular in the temperature range from 80.degree. to 130.degree. C.
