METHOD FOR DYEING WITH SULPHUR AND SULPHUR VAT DYES |
| 摘要 |
The invention relates to a method for the dyeing of fibre materials with sulphur dyes with regeneration of the dyeing redox potential, characterised in that during the dyeing process the dye liquor is circulated between the dyeing plant and a connected electrolytic cell and the sulphur dye which is undesirably oxidised in the dyeing vat is cathodically reduced in the electrolytic cell.
