- the present invention relates to surface active compositions. lt also relates to the use of such compositions in the dyeing of polypeptide fibres, especially wool, so as to obtain a rapid fixing of the dyestuffs without affecting the evenness of the shades.
- the dyeing temperature can be appreciably lowered, the period of treatment can be reduced and the operation can be effected at a lower pH which is near to the isoelectric point of the material, while obtaining an excellent tinctorial yield as well as general fastness equivalent to that obtained by the prior technique.
- Lowering of the pH of the dyebath is not itself normally effected without difficulties, since a more acid pH considerably increases the affinity of the dyestuff for the fibres and this increase is not compensated by the loweringof the temperature. Lack of evenness was to be feared.
- the process according to the present invention enables uniform shades to be obtained with a variety of anionic dyestuffs used for dyeing wool.
- dyestuffs are characterisedgenerally by the fact that they possess sulphonic or carboxylic groups and consequently may belong to the class of acid dyestuffs as defined in the Colour lndex (Volume l, 1956, page 1,001) or to the class of the mordant deystuffs (Colour Index, page 1,405).
- the dyestuffs described in US. Pat. specification No. 3,547,572 or British Pat. specification No'. 1,001,182 maybe particularly mentioned.
