A method for treating a textile substrate comprising cellulosic fibres with an aqueous treatment liquor containing a mixture of (a) a secondary hydrophilic sulphonated n-paraffin containing at least 9 carbon atoms, and (b) an orthophosphoric acid triester, the weight ratio a:b being of from 1.4-4.0:1. This mixture of anionic and non-ionic wetting agents is particularly suitable for use in an aqueous medium having a high electrolyte content. |
