Our Sulphur Dye Journey ✦
From producing Sulphur Black to synthesising it from its raw materials, and on to a patented ecological product and a full colour range.
Sulphur Black production begins
MKS DevO starts manufacturing Sulphur Black for the textile and denim industry.
In-house synthesis via DNCB route
Transition to synthesising Sulphur Black from dinitrochlorobenzene (DNCB): full control from raw material to finished dye.
SULTAN BLACK ECO patent
Patent granted for a sulphide-free ecological sulphur dyeing system.
SULTAN® Colour Range launched
Full range of colour sulphur dyes brought to market for denim and garment dyeing.
SULTAN BLACK ECO
SULTAN BLACK ECO, used with sulphide-free reducing agent ECONSIDANT, halves the number of wash baths required compared to conventional sulphur dyeing.
Conventional Sulphur Dyeing vs SULTAN BLACK ECO ✦
The chemical challenge of conventional sulphur dyeing and how our patented drop-in ecological system resolves it.
What happens to the sulphide?
Wastewater leaves the dyehouse at pH 11–14 and must be acidified before biological treatment.
Elemental sulphur precipitates and SO₂ gas must be scrubbed before discharge.
- Toxic, malodorous hydrogen sulphide gas emissions
- Severe odour complaints from the wastewater plant
- High regulatory scrutiny from environmental authorities
SULTAN BLACK ECO + ECONSIDANT
SULTAN BLACK ECO: Patented, non-sulphide Sulphur Black dye.
ECONSIDANT: Sulphide-free reducing agent.
Wastewater Advantages
- Can be acidified without risk of toxic H₂S emission
- After filtration: completely colourless and harmless
- Easily treated and recyclable for process reuse
- Dye lost during washing is recovered for reuse
Drop-in System Benefits
- No change to existing production method
- No new machinery investment required
- No additional parameters to monitor
- Usage levels similar to conventional dyes (same g/L)
- No more odour from the wastewater plant
- No sulphur or SO₂ handling cycle
- Confidence with environmental authorities
