Definitions

• polyglycol ether derivatives containing on an average 20 to 70, preferably 25 to 40, ethenoxy (CH CH -O) groups, of primary or secondary amines containing at least one higher aliphatic residue bound to the amino group or water-soluble salts of acid esters which are derived on one hand from polybasic acids and on the other hand from these polyglycol ether derivatives, can be used as levelling agents in wool dyeing.
• levelling agents are conventionally used in an amount of about 0.1 to 8 by weight, advantageously of 0.5 to 3% by weight, calculated on the Weight of the material to be dyed.
• levelling agents of the kind defined above produce very level dyeings on wool fabrics, dyeing of wool yarn with wool dyestuffs, more especially when the wool yarn is dyed in apparatus by the so-called suspension dyeing method, in the presence of the levelling agents refer-red to, the wool yarn generally suffers a varying degree of sticking together, as a result of which the dyeing finally obtained is correspondingly patchy.
• the wool yarn in hank form undergoes practically no sticking and very level dyeings can be obtained by using dyebaths that contain in addition to the wool dyestuff and the levelling agent defined above (a) Paraffin oil in an amount of over 100, preferably of about 150, percent by weight, referred to the levelling agent,
• a silicone defoaming agent in an amount of at least 0.1% by weight referred to the levelling agent.

• wool dyestuffs for example complex chromium or cobalt compounds of monoazo dyestuffs in which 1 atom of chromium or cobalt is bound in complex union to 2 molecules of azo dyestuff, the molecule of the complex compound being free from any acid groups imparting solubility in water.
• wool dyestuffs that contain at least one acid group imparting solubility in water, that is to say a carboxylic acid group or a sulphonic acid group not participating in the formation of the metal complex, such as acid wool dyestuffs that are free from metal bound in complex union; complex chromium compounds, containing sulphonic acid groups, of monoazo-dyestuffs in which 1 atom of chromium is bound in complex union with 1 molecule of azo dyestuff; water-soluble reactive dyestuffs and complex chromium or cobalt compounds of monoazo dyestuffs in which 1 atom of chromium or cobalt is bound in complex union with 2 molecules of azo dyestuff, and the molecule of the complex compound may contain one or more than one acid group imparting solubility in water.
