Neutral dyeing of wool and wool/polyester blend fabrics using sulphatoethylsulphone reactive-disperse dyes

摘要

Two models of temporarily anionic sulphatoethylsulphone reactive disperse dyes were applied to wool, polyester and wool/polyester blend fabrics at different dyeing pH. Maximum exhaustion values and colour yield were observed at pH 7. The results showed that reactive disperse dyes containing bis-sulphatoethylsulphone reactive groups were more convenient for neutral dyeing of wool and wool/polyester blend fabrics if compared with a dye containing a mono-sulphatoethylsulphone group. Excellent to very good wet fastness properties on all dyed fabrics were achieved.
