Application of sodium benzoyl thiosulphate from aqueous solution to wool and its effect on substantivity of disperse dyes. Part 2: modification of wool with sodium benzoyl thiosulphate

摘要

Sodium benzoyl thiosulphate was applied to wool fabric from aqueous solutions in order to covalently bind benzoyl groups to the fibre and thus impart disperse dye substantivity to the modified wool. The modified wool fabric was dyed with a selected model disperse dye, CI Disperse Blue 56, and the wash fastness properties of the dyeings assessed.
