• For cellulosic substrates: standard sulphur dye vat reduction → exhaustion → oxidation (air/bleaching agent) → wet-fastness improvement steps.
• Control oxidant levels carefully to avoid excessive discoloration or loss of shade.
• Test on pilot/production scale to optimize liquor ratio, temperature profile and post-treatment.
