Definitions

  • the present invention relates to a process for the dyeing of shaped articles made of aromatic polyesters or cellulose triacetate in an aqueous medium with disperse or ingrain dyestuffs. More particularly it concerns a process wherein the dyeing is carried out in the presenc of carriers which are naphthalene derivatives of the general formula R CH OR (I) in which R, represent a naphthyl radical or tetrahydronaphthyl radical which may be substituted by alkyl groups with 1-4 carbon atoms and/or by halogen atoms and R stands for an alkyl or acyl radical with 1-4 carbon atoms.
  • carriers which are naphthalene derivatives of the general formula R CH OR (I) in which R, represent a naphthyl radical or tetrahydronaphthyl radical which may be substituted by alkyl groups with 1-4 carbon atoms and/or by halogen atoms and R stands for an alkyl or acy
  • Compounds of the Formula I can be obtained in a simple manner, for example, from chloromethyl-naphthalenes or 1,2,3,4 tetrahydro-6-chloromethyl-naphthalenes by reaction with alcoholates or salts of carboxylic acids in an alcoholic solution.
  • naphthalene derivatives are particularly effective in the Formula I of which R stands for a radical which contains only one or two carbon atoms, for example 1-methoxymethyl-naphthalene, l-ethoxymethyl naphthalene, 1,2,3,4-tetrahydro-6-methoxymethyl naphthalene as well as the formyl and acetyl derivatives of 1-hydroxymethyl-naphthalene and 1,2,3,4 tetrahydro-6-hydroxymethyl-naphthalene.
  • R stands for a radical which contains only one or two carbon atoms
  • the process according to the invention enables shaped articles, for example, filaments, fibres, foils and fabrics Patented Feb. 9, 1971 of aromatic polyesters, e.g. those of polyethylene glycol terephthalate or condensation products obtained from terephthalic acid and 1,4-bis-hydroxymethyl-cyclohexane, or of cellulose triacetate to be dyed with disperse or ingrain dyestuffs in deep shades with a substantial acceleration of the dyestuff absorption.
  • aromatic polyesters e.g. those of polyethylene glycol terephthalate or condensation products obtained from terephthalic acid and 1,4-bis-hydroxymethyl-cyclohexane
  • cellulose triacetate e.g. those of polyethylene glycol terephthalate or condensation products obtained from terephthalic acid and 1,4-bis-hydroxymethyl-cyclohexane
  • the compounds of the Formula I are water insoluble, care'must be taken that they are present in the dyebath in emulsified form.
  • they can be added in the form of solutions in organic solvents, e.g. isopropyl alcohol, to the dyebaths containing an emulsifier or an emulsifier mixture.
  • organic solvents e.g. isopropyl alcohol
  • mixtures of compounds of the Formula I, optionally in combination with known carriers, and emulsifiers to the dyebath.
  • Suitable emulsifiers are primarily anionactive and/ or non-ionic compounds. In general amounts of emulsifiers of 15 to 30%, preferably 25%, referred to the weight of the used compounds of the Formula I or the used mixtures of the compounds of the Formula I and other carriers have proved.
  • Disperse and ingrain dystuifs which are suitable for the process according to the invention are described, for
  • the dyeing of the shaped articles made of aromatic polyesters or cellulose triacetate with dispersion or ingrain dyestuffs in the presence of the compounds of the Formula I is usually performed in a long bath at temperatures of about C.
  • the compounds of the Formula I are liquid, even at temperatures below 0 C. Difficulties as are encountered in the use of crystalline products do therefore not occur. Further remarkable features are the low steam volatility, the absence of annoyance through odour and the nontoxicity.
  • Fibres of polyethylene glycol terephthalate are introduced in a liquor ratio of 1:40 into an aqueous bath containing, per litre, 0.75 g. of the disperse dyestuif l-hydroxy-4-(p-tolylamino)-anthraquin0ne and 2 g. sodium oleyl-methyl-tauride.
  • 4 g. 1-methoxymethyl-naphthalene which were previously mixed with hot isopropyl alcohol are then added with stirring and dyeing is carried out at 96-98 C. for 2 hours. The material is subsequently rinsed and dried. A blue dyeing of very good fastness to light is obtained.
  • Fibres of cellulose triacetate are introduced in a liquor ratio of 1:40 into an aqueous bath containing, per litre, 0.75 g. of the disperse dyestuff 1-amino-4-hydroxy-2- bromo-anthraquinone and 2 g. sodium dina'phthyl-me'thane disulphonate. 4 g. 1-methoxymethyl-naphthal ne which were previously mixed with hot isopropyl alcoho are added with stirring. After the usual dyeing time of 2 hours, a red dyeing of very good fastness to light is obtained.
  • EXAMPLE 3 The procedure is as described in Example 1, but with the difference that the carrier is applied in the form of the mixture described below, which is added to the hot dyebath in an amount of g. per litre.
  • the mixture consists of 80 parts 1-methoxymethyl-naphthalene, 12 parts of the monoethanolamine salt of tetrapropylene-benzenesulphonic acid and 8 parts of the reaction product of one mole o-benzylphenylphenol with 16 moles ethylene oxide. A deep blue dyeing of very good fastness to light is obtained.
  • EXAMPLE 4 The procedure is as described in Example 1, but with the difference that the carrier is applied in the form of the mixture described below, which is added to the hot dyebath in an amount of 5 g. per litre.
  • the mixture consists of 40 parts 1-methoxymethyl-naphthalene, 40 parts 1-acetoxymethyl-naphthalene, 12 parts of the monoethanolamine salt of tetrapropylene-benzenesulphonic acid and 8 parts of the reaction product of one mole o-benzylphenylphenol with 16 moles ethylene oxide. A deep blue dyeing of very good fastness to light is obtained.
  • EXAMPLE 5 The procedure is as described in Example 1, but with the difference that the carrier is applied in the form of the mixture described below, which is added to the hot dyebath in an amount of 5 g. per litre.
  • the mixture consists of 40 parts 1-methoxymethyl-naphthalene, 20 parts benzylphenyl ether, 20 parts diphenyl ether, 12 parts of the monoethanolamine salt of tetrapropylene-benzenesulphonic acid and 8 parts of the reaction product of one mole o-benzylphenylphenol with 16 moles ethylene oxide. A deep blue dyeing of very good fastness to light is obtained.
