Definitions

• these oligomers are in general not dyed, for example by disperse dyestuffs, they turn out On the dyed material in the form of a white dust; this White dust appears particularly in spinning mills and weaving and knitting shops, where it deposits on the machine parts which come into contact with the dyed material.
• the compounds of the Formula I used according to the invention ma be prepared, for example, by esterification of 1 mol of an addition product of 8-24 mols of ethylene oxide and 1 mol of butanediol-(l,4) with 2 mols of a straight chain or branched alkaneor alkene-monocarboxylic acid having 12 to 22 carbon atoms.
• esterification mixtures of the mentioned carboxylic acids may also be used.
• condensation products of the Formula I are distinguished by their essentially simpler application and, in many cases, by an improved dispersing action for the disperse dyestuffs used for the dyeing of polyester materials, which is also maintained when the dyeing process is carried out at high temperature conditions (120130 C.).
• the quantity of the compounds of the Formula I to be added according to the invention for obtaining level dyeings varies between 0.25 and g., in particular between 1 and 3 g., per liter of dyebath; the concentration of the auxiliary agent depends on the depth of the dyeing and on the disperse dyestuffs to be levelled.
• the use of the mentioned condensation products in dyeing according to the invention is not bound to a determined temperature; in general, the temperatures used are within the range of from about 98 C. to about 140 C. and the dyeing is effected according to the exhaust method in the usual manner, optionally in the presence of carriers.
• Dyeings produced without the use of the compounds of the Formula I and which are unlevel, can be levelled by an after-treatment with the said auxiliary agent.
• the compounds are used in quantities of 4 to 5 g. per liter of after-treating bath during a treatment time of 1 to 3 hours at boiling temperature or under high temperature conditions.
• disperse dyestuffs there may be used in the process according to the invention the products known for the dyeing of polyester materials, for example those of the series of azo and anthraquinone dyestuffs.
• EXAMPLE 1 100 kg. of a combed material of polyethylene glycol terephthalate fibers, packed as closely as possible, were dyed at 120 C. for 90 minutes, in a high temperature dyeing apparatus, at a goods-to-liquor ratio of 1:15, with an aqueous bath containing, referred to the dry weight of the goods,
• EXAMPLE 2 A fabric having the tendency to crease formation and a weight of about g./m.'-, in linen weave pattern from yarns having the size Nm 48/2, consisting of polyethylene glycol terephthalate staple fibers of 3.3 d. tex 60 mm. cutting length, a density of the weft of 130 yarns per 10 cm. and a number of warp yarns of 1700 yarns over a web width of 130 cm., was dyed, after the prewashing and thermofixation usual for this kind of goods, for 30 seconds at C. on a winch beck, at a goods-toliquor ratio of 1:30, in the following manner:
• the fabric was entered into the bath which contained, per liter of water, 2 g. of butanediol-(1,4)-pentadecaglycolether dioleyl ester and 3 g. of a carrier on the basis of methyl-naphthalene, and which had been adjusted to pH 5.5 by means of sulfuric acid and had a temperature of 60 C., and the fabric was allowed to run through the bath for 15 minutes. 7
• EXAMPLE 3 50 kg. of texturated polyester rayon, which had been dyed for 1 hour at 125 C. in a high temperature apparatus, at a goods-to-liquor ratio of 1: 15, in an aqueous bath with disperse dyestuffs, were subjected, after completion of the dyeing, without cooling the goods and without intermediate rinsing, to the following reducing cleaning process:
• a bath was prepared which contained per liter of water, in addition to cc. of sodium hydroxide solution of 36 B. and 2 g. of hydrosulfite, 3 g. of a condensation product of butane-diol-(1,4)-pentadecaglycol ether and oleic acid in a molar ratio of 1:2.
• This bath was heated to 90 C. and pumped into the dyeing apparatus in which the dyeing had been carried out under high temperature conditions and which contained the not cooled material of polyester rayon.
• the bath was cycled for minutes at 90 C. and the dyeing was then rinsed with water under overflow until it was free from alkalies.
• polyester rayon so treated showed practically no oligomer deposits, neither in the form of dust nor in the form of solid particles which could have formed by auxiliary agents in combination with the oligomers.
• a process for dyeing, with a disperse dyestufi, fibrous materials of linear polyesters and blends thereof with cellulose or polyamide fibers the improvement which comprises applying to the material a levelling compound of the formula in which R -CO- and R2-c0 are radicals of straight chain or branched alkaneor alkene-monocarboxylic acids of 12 to 22 carbon atoms, and n and m each represent numbers from 4 to 12.
• levelling compound is applied in a concentration of between 4 and 5 g. per liter of after-treating liquor.
• levelling compound is butanediol-(1,4)-pentadecaglycol dioleyl ester.
