Definitions

• wool has normally not been subjected hitherto to a pretreatment in order to be dyed level.
• German Pat. No. 1,290,519 describes a process for the streak-free dyeing of polyamide fibers with reactive dyestuffs, wherein auxiliary agents on the basis of triazine derivatives are added to the dyebath to promote uniform absorption of the dyestuffs.
• auxiliary agents on the basis of triazine derivatives are added to the dyebath to promote uniform absorption of the dyestuffs.
• other auxiliary levelling agents that have a different action and also a different chemical constitution are also added to the dyebaths.
• Level dyeing may also be promoted by a more careful selection of the dyestuffs which are suited for this purpose.
• Me represents a salt-forming cation, preferably an alkali metal ion, and by effecting the dyeing with the reactive dyestuffs in the usual manner, preferably at elevated temperature according to the exhaust method.
• the pretreatment of the fibrous material is generally carried out with a goods-to-liquor ratio of 1:25 to 1:5, preferably 1:10 to 1:15, in the following manner:
• the wool provided in known manner with an antifelting finish and having the form of combed material, of yarn in hanks, of bobbins or of piece goods is heated in a liquor acidified with acetic acid to pH 5, starting at 40 C, within 30 minutes to the boiling temperature with one of the mentionedproducts of the formula (I) in a quantity of 0.5% to 5%, referred to the weight of the dry goods, and" 0.01% to. 0.5% of a non-ionic auxiliary agent, for example an oxethylated nonylphenol, treated for 15 minutes at the boiling temperature and then rinsed warm and cold with water.
• a non-ionic auxiliary agent for example an oxethylated nonylphenol
• triazine derivative of the formula (I) inversely depends on the intensity of the shade to be dyed later on; thus, for darker dyeings smaller quantities of product are applied.
• the wool yarns were dyed on a hank yarn dyeing machine at a goods-to-liquor ratio of 1:15 with the bath aqueous medium may also be effected by impregnation described hereinafter data referring to the weight of (padding, nip-padding, spraying, etc.) and dwelling or d l) i th following manner: y mp gn and Steamingthe aqueous bath having 40 C and a pH-value of 5 It is also possible to apply the compounds of the fordj d i h acetic id) t i d mllla fmm Organic Solvents Onto the Substrate and 0.1 of a non-ionic auxiliary agent on the basis of to remove the solvents during fixation by steaming or 10 the reaction product f 1 l f l h l d suction. 10 moles of ethylene oxide,
• dyestuffs which contain 1 of the product f the f l a vinyl-sulfone group or which form such a group under the dyeing conditions and which react over this group with the reactive groups of the polyamide fibers, for example dyestuffs which contain sulfatoethylsulfone, C1 chloroethylsulfone, methyltaurinoethyl-sulfone or thiosulfatoethylsulfone groups; C
• dyestuffs which react with the fiber of a substituted or unsubstituted acrylamide group, for example dye- I f stuffs which contain a-bromo-acrylamideor B-(2,2,3,- -Q 3-tetrafluoro-cyclobutyl)-acryloylamino groups;
• dyestuffs which contain the following atom groupings as reactive groups: monoand di-chlorotriazine, trichloropyrimidine, monochloro-diflu-oropyrimidine, mono-chloroacetic acid amide, chloroor sulfatopropylamide, alkyl-sulfone-propylamide, dichloro- 3O phthalazine, benzochlorothiazole, dichloropyridazone, Aft h i i t d d th ll i l i t th dichloropyrazine and methylsulfonyl-methylbath, this pretreatment bath was heated within minchloropyrimidine.
• the bath was then heated within 35 minutes to 75 C and the goods were treated for 30 minutes at this temperature.
• the dyebath was then heated within 25 minutes to the boiling temperature and the fibrous material was dyed for 60 minutes at the boiling temperature.
• 2.5 of sodium trichloroacetate were added after a boiling period of 40 minutes to the bath in order to improve the fastness.
• the dyed goods were then rinsed with water in the usual manner at first warm and then cold. A very level brown dyeing was obtained on the wool.
• the third dyestuff listed above may be prepared according to the procedure disclosed in Example 5 of US. Pat. No. 3,802,837.
• EXAMPLE 2 Fully fashioned (confectioned) knit goods of undyed wool, the fibrous material of which had been provided in the form of combed material in a back-washing machine with an anti-felting finish, were pretreated on a paddle dyeing machine at a goods-to-liquor ratio of 1:20 in an aqueous bath in the manner described in Ex ample 1, but using 3 of the product described in said Example, in order to compensate affinity differences of the wool, and then dyed, likewise at a goods-to-liquor ratio of 1:20, in the following manner:
• the aqueous dyebath having a temperature of 50 C was combined with 0.74% of the reaction product of 1 mole of stearylamine and moles of ethylene oxide,
• EXAMPLE 4 Knit goods of undyed wool that had been provided in the form of combed material with an anti-felting finish were pretreated on a jet dyeing machine in the manner described in Example 1 with the product described in said Example in order to compensate affinity differences of the fibrous material and then dyed likewise according to the method described in Example 1 using 3% of the reactive dyestuff of the formula and aftertreated. A level scarlet dyeing was obtained.
• a process for the level dyeing of wool having an anti-felting finish of polyimine or polyamine resin, with fiber-reactive dyestuffs wherein, prior to the dyeing, the wool having the anti-felting finish is pretreated with a compound of the formula in which R is hydrogen or an alkyl radical having up to four carbon atoms, A is phenylene, Z is an anionic group selected from the group consisting of SO (H,Me) O-SO (H,Me) COO(H,Me) SO -CH -CH -OSO (H,Me),
• X is chlorine or the group and Me is an alkali metal ion; and the dyeing with the said reactive dyestuffs is then effected.
