Dyeing process and dye composition. |
摘要 |
A process for dyeing fibrous substrates which comprises the steps of: providing a fibrous substrate; providing at least one sulfur dye; providing at least one reduction stable direct dye; and applying said reduction stable direct dye and sulfur dye to said fibrous substrate in the presence of a suitable reducing agent. Further, it has been surprising to find that these reduction stable direct dyes can be processed without a sulfur dye present. This results in a process for dyeing fibrous substrates which comprises the steps of: providing a fibrous substrate; providing a reduction stable direct dye; and applying said reduction stable direct dye to said fibrous substrate in the presence of a suitable reducing agent. |
