Why It Matters
Disperse dye fails to migrate uniformly into polyester/blends, leaving specks and uneven coloration
Solution Approach
Disperse dye fails to migrate uniformly into polyester/blends, leaving specks and uneven coloration RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Processing Workflow
1
Substrate & Process Assessment
Identify the fiber and process stage (pretreatment, dyeing, finishing) and the performance, hand, and compliance targets.
2
Auxiliary Selection
Match surfactants, wetting and dispersing agents, softeners, fixatives, or pH and sequestering agents to the substrate and bath chemistry.
3
Lab Dip & Dosing
Confirm dose and sequence on a lab dip or pad trial, checking levelness, fastness, hand, and bath stability.
4
Production Validation
Verify reproducibility, fastness, and effluent compliance at scale, and set the recipe and packaging for production.
Recommended Chemistries (5)
Benzyl Alcohol
CAS 100-51-6
Solvents
Dyeing carrier for polyester
carrier that plasticizes/swells polyester so disperse dye can diffuse into the fiber at the boil
Melting Point: -15 °C Boiling Point: 205 °C at 760 mmHg Density: 1.05 at 824 °C
Full Details
Dispersing Agent (Naphthalene Sulfonate Condensate)
CAS 36290-04-7
Surfactants
Dye dispersant
keeps disperse dye finely dispersed in the bath, preventing aggregation and spotting
Full Details
Levelling Agent (Ethoxylated Fatty Amine)
CAS 61791-26-2
Surfactants
Migration and levelling aid
promotes dye migration across fibers for a level shade
Full Details
Ethylene Glycol
CAS 107-21-1
Glycols & Polyols
Co-solvent and humectant
co-solvent/humectant supporting the carrier system (benzyl alcohol is the primary swelling carrier)
Melting Point: -13 °C Boiling Point: 198 °C at 760 mmHg Density: 1.115 at 20 °C
Full Details
Acetic Acid
CAS 64-19-7
Acids & Salts
pH adjustment for enzyme activity
2789 (ACETIC ACID, GLACIAL) · Class holds the bath at pH 4.5-5, the optimum window for disperse dyeing
Melting Point: 17 °C Boiling Point: 118 °C at 760 mmHg Density: 1.051 at 20 °C
