• oxazolines substituted in the above-mentioned way there are used, for instance, the addition compounds of ethylene oxide and/ or propylene oxide to 2-hexyl-4-methyl 4-hydroxy-methyl-oxazoline, 2,-undecyl-4-ethyl-4-hydroxy-methyl-oxazoline, Z-heptadecyl-4-ethyl-4-hydroxymethyl-oxazolineor Z-undecyl-4,4abis-hydroxy-methyloxazoline.
• the oxazolines can be prepared according to known methods, for instance, according to US.
• Patent 2,504,951 from saturated or unsaturated monocarboxylic acids, such, for instance, as tallow oil fatty acid or coconut oil fatty acid, by reaction with alkylol-amines-( 1,2) containir; at least 2 hydroxy groups, such, for instance, as 2 amino-Z-ethyl-propanediol-(1,3), Z-amino-Z-methyl-propanediol-(L3) or the tris-hydroxy-methyl-aminomethane with splitting ofi of 2 mols of water at an elevated temperature and, if desired, under reduced pressure.

• alkylol-amines-( 1,2) containir at least 2 hydroxy groups, such, for instance, as 2 amino-Z-ethyl-propanediol-(1,3), Z-amino-Z-methyl-propanediol
• hydroxy groups of the substituted oxazolines thus obtained can then be reacted according to known methods, for instance, according to the operating method described in German patent application No. 1,027,672 laid open to public inspection, with epoxides, such, for instance, as ethylene-oxide, or propylene-oxide or mixtures of said epoxides.
• epoxides such, for instance, as ethylene-oxide, or propylene-oxide or mixtures of said epoxides.
• epoxides such, for instance, as ethylene-oxide, or propylene-oxide or mixtures of said epoxides.
• the dyestuffs used and the fibrous material to be treated, the oxazoline compounds used as levelling agents according to the inveution are used in varying quantities. The most favorable amount for each treatment can be easily ascertained .by a dyeing test.
• the oxazoline compounds claimed are likewise excellently suitable for the additional levelling of unequal dyeings.
• the dyeings are additionally treated at an elevated temperature with an aqueous bath containing the oxazoline compound generally under the same conditions under which the dyeing is carried-outQ v
• the levelling agents according to the invention can be applied together with the usual dyestuffs, for the levelling of all dyeings realized on nitrogen-containing fibers and cellulose fibers according to known dyeing methods.
• Nitrogen-containing fibers comprise polyamide fibers, above all protein fibers, such as wool and silk. Most suitable for the dyeing of said nitrogen-containing fibers are, above all, those of the series of the so-called acid dyestulfs.
• cellulose fibers there are used native and regenerated cellulose fibers.
• dyestuffs which may be used for the dyeing of cellulose fibers there are mentioned, for instance, substantive dyestuifs and vat dyestufis which are used in the form of their sodium-leuco compounds.
• a completely unsatisfactory levelling effect is obtained together with a very uneven dyeing of the added yarn.
• insufficient levelling effects are obtained by adding in each case 0.1 or 1.5 g./l. of polyglycol of an average molecular weight of 1000 or 0.1 or 1.5 g./l. of the addition compound of mols of ethylene-oxide to 1 mol of dodecyl alcohol.
• levelling effects are realized by simultaneously using in each case 0.1 or 1.5 g./l. of the addition compound of mols of ethylene-oxide to 1 mol of Z-undecyl-4,4-bis-hydroxymethyloxazoline.
• a distinct levelling effect is observed together with an improved evenness of the dyeing, but no remarkable retardation effect occurs. Only with quantities of 1.5 g./l.
• Example 2 On the same material and in the same Way as described in Example 1 a dyeing is produced with 2% of the dyestulf C.I.6O 010 (cf. Colour Index, 2nd edition (1956)) according to the .IN-process and levelling tests are then carried out as described in Example 1.
• Example 3 As described in Example 1, a dyeing is obtained with 2% of the dyestuff C.I.59800 (cf. Colour Index, 2nd edition (1956)) according to the IN-process and levelling tests are likewise carried out as described in Example 1. With the blank IN-vat and compounds such as the addition compound of 15 mols of ethylene-oxide to 1 mol of stearyl alcohol or polyglycol of a molecular weight of 600 in quantities of 0.1 or 1.5 g./l. in each case, a completely unsatisfactory result is obtained, whereas with 0.1
• Example 4 10 weight units of a Wool gabardine (20 grams) are divided into a larger piece of 4 Weight units (8 g.) and into 6 smaller pieces of 1 Weight unit (2 grams) each, thoroughly Wetted and then centrifuged in a uniform way.
• the large piece of 4 weight units is first introduced into the boiling dyebath containing 1% of the wool dyestuif C.I.24 800 (cf. Colour Index, 2nd edition (1956)), 5% of sodium sulfate and 4% of acetic acid. After 2, 4, 8, 16, 32 and 64 minutes each a small piece of a weight-unit of one is added and boiling is continued for a further 56 minutes, after the last piece has been added. Total boiling time: 2 hours.
• the goods-to-liquor ratio amounts to 1:40 calculated on the total wool material (:800 cc.). Evaporated water is replaced after a boiling time of 1 hour. (Kramrisch test, B. Kramrisch, J. 502. Dyers and Coll., May 1959, pages 242 et seq.)
• the dyestuff is nerly completely absorbed prior to the addition of the last pieces of the wool gabardine, a good levelling effect between the Wool pieces added at first to the dyebath and those added at last can be observed, if in each case 0.1 or 2 g./l. of the addition compound of 12 mols of ethylene-oxide to 1 mol of 2-undecyl-4-ethyl- 4-hydroxymethyl-oxazoline are added in low concentrations.
• Example 5 A previously cleaned cross-wound bobbin (as described in Example 1) is dyed at a goods-to-liquor ratio of 1:10 in the closed apparatus with 0.2% of the dyestuff C.I.70 035 (cf. Colour Index, 2nd edition (1956)) according to the IN-process in the usual manner for 45 minutes at 50-60 C. Per liter of dyebath 20 cc. of sodium hydroxide solution (38 B.) and 4.5 grams of sodium-dithionite are used. The bobbin is badly dyed through and the dyeing is unlevelled.
